Introduction

Mosquitoes have been described as the most dangerous creatures on Earth.

Aedes mosquitoes may carry yellow fever and dengue fever. Culex mosquitoes may carry several
strains of encephalitis (including St. Louis Encephalitis, Eastern Equine Encephalitis and West
Nile Virus), and Anopheles mosquitoes may carry malaria.

Male mosquitoes do not bite. The real risk is from female mosquitoes which bite when in search
of blood to provide protein for their eggs.

Scientific research over the past 50 years has shown that female mosquitoes find their prey
using a combination of sensory cues including light, shape, color, heat, vibration, sweat and
other by-products of human activity.

Using that research and with the benefit of extensive field testing (including tests by the United
States Department of Agriculture in Gainesville, Florida), Mega-Catch has developed one of
the worlds most advanced mosquito traps: the Mega-Catch ULTRA Mosquito Trap.

Features of Mega-Catch ULTRA Mosquito Trap

The Mega-Catch ULTRA Mosquito Trap has been designed for outdoor use only. The ULTRA
can operate unattended for long periods. It can be programmed to start and stop according
to peak mosquito activity in your area. It features an electronically controlled diode lighting
system that produces intermittent light at oscillating frequencies selected to coincide with
spectral sensitivity peaks for many mosquito species. It also features a low-intensity U.V. or
black light Bulb.

Mosquitoes attracted to the ULTRA by visual and other cues seek to land on and probe specially
designed surfaces and enter the Trap where they are collected in the Catch Bag or Liquid Catch
Container.

The ULTRA also features the Mega-Catch Variable Quantity Slow CO

Gas Release System.

2

Use of this attractant system is entirely optional. The system enables the ULTRA to replicate
a key element of human respiration by releasing small quantities of carbon dioxide (CO2) gas
at an exponentially decaying (negative) rate over fixed intervals to produce a concentration
gradient in the air plume emanating from the lower part of the Trap. The CO2 plume will, in
optimum conditions, attract mosquitoes from a distance of up to 150 feet (45 meters).
Mosquitoes are able to navigate their way to the Trap by following the CO2 gas plume up wind.

CO

is a natural product and is used extensively in the beverage industry to aerate (put bubbles

2

into) the likes of beer, softdrinks and sparkling mineral water. CO2 is able to be purchased from
gas supply outlets throughout the U.S.A. and elsewhere (see page 13, CO2 Gas Suppliers section).

Quantities of CO2 gas released by the ULTRA can be adjusted between 5 settings by a simple
touch of the Gas Select Button on the Programmable Timer. A 20lb (9kg) CO2 Gas Cylinder
used at the recommended settings should last for up to 4 months (see page 12-13, Operation
of Variable Quantity Slow CO2 Gas Release System section).

Initial Set Up Instructions

Before attempting operation of your ULTRA Trap, follow these instructions:

1. Remove the Trap from the carton.

2. Remove the box containing the Stand from the carton.

3. Assemble the Stand (see Page 9 - Stand Assembly Instructions section).

4. Remove the box marked Accessories from the base of the carton.

5. Fit the External Skirt to the outside of the Trap by sliding the skirt on from the top of

the Trap so that the opening is directly in front of the Door (see Page 18 - Fitting of

External Skirt section).
Note: Failure to position the Skirt correctly will result in a NIL mosquito catch.

11. Hang the Trap from the hook on the Stand in the direction shown in the Stand Assembly

ULTRA Trap has two mosquito collection methods: a dry-catch system using a

Catch Bag and a wet catch system using a Catch Container. In most circumstances the
wet-catch system offers superior catch performance to the dry-catch system. The dry­catch system using the Catch Bag is better for mosquito species identification.

base of the Fan inside the Trap. The Catch Bag has an elastic top to facilitate attachment
(see Page 16, Mosquito Catching Systems section).

Container two-thirds full with fresh water. Add 2 or 3 drops of liquid detergent / soap
to break the surface tension of the water. Also add 3 or 4 teaspoons of a non-diet
(sugar-based) soft drink. Then place the Liquid Catch Container in the Trap using the
locating feet on its base.

touch the exposed holes on its surface. Place the strip inside the Trap (see Page 22,

has been completed.

until Door clicks into place. Lock the Door using one of the two Keys provided with the
Trap and then remove the Key. (NOTE: Removing and reinstalling the door is designed
to require a reasonable amount of force to make it difficult for children.)

Instructions. To achieve this, hold the Trap in an upright position so that the top of the
Trap is next to the hook on the stand. Then swing the bottom of the Trap outwards
(through an arc of about 45 degrees) and you will see that the top of the Trap will fit
through the gap in the hook. This is a design feature to prevent the Trap falling off the
stand accidentally.

Gas Suppliers section). Having obtained a CO2 cylinder, connect the

2

Low-Pressure Gas Regulator (supplied with the Trap) to the Gas Cylinder ensuring
beforehand that the O ring on the Gas Regulator is properly in place and undamaged.
Then connect the Regulator to the Trap (see page 11, Connecting the ULTRA to the

CO

Gas Supply section). Slowly turn on the CO2 gas checking for leaks. Set the gas

2

setting using the Gas Select button on the Programmable Timer (see page 12-13,

Operation of Variable Quantity Slow CO

Gas Release System section). Setting #1

2

is low. Setting #5 is high. (NOTE: you will need to reset the gas setting if the power
is turned off).

13. Your

ULTRA Trap comes with a low-voltage transformer and a 60-foot (18-meter) low-

voltage extension cord with weatherproof connectors. Plug the extension cord into the
Trap connection turning the connector clockwise until tight. Plug the extension cord
into the transformer cable turning the connector clockwise until tight. Then plug into
the power supply. (NOTE: The connectors are designed to be a tight fit to ensure that
they are weatherproof.)

14. Turn on the power. A display should appear on the face of the Timer. (If it does not,
see Page 14-15, Operation of the Programmable Timer section). Set the Timer to
"ON" for continuous running or to "AUTO" to program operating times. See Page 14­15, Operation of the Programmable Timer section for programming instructions.

15. If the U.V. Bulb inside the Trap is not on then turn it on by touching the switch on the
Programmable Timer which is marked U.V. Tube. When the Trap is operating, the Fan
should be running, the four Diode Lights should be flashing intermittently, the U.V. Bulb
should be on (unless switched off) and the Trap should click every 75-80 seconds. If
the Trap is not operating correctly then re-read these instructions or refer to page 28
Problem Solving section, or email us at [e-mail].

What Your Mega-Catch Mosquito Trap Will Do

Your Mega-Catch Mosquito Trap is designed to reduce mosquito populations, but it will not
permanently eliminate them. Operate the Mega-Catch Mosquito Trap daily for several weeks.
Over this time you should notice a decline in mosquito numbers. This means your Trap is doing
its job. (NOTE: Rain will probably result in a new infestation.)

The Mega-Catch Mosquito Trap is not designed to compete with humans in close proximity
eg: at a barbecue. If you are planning an outdoor function, operate the Trap for several days
before the function.

NOTE: Your Mega-Catch Mosquito Trap should be used in conjunction with other sensible
control measures designed to manage mosquito problems.

Installing and Siting the Mega-Catch Mosquito Trap

Installation of Trap:

Your Mosquito Trap comes fully assembled. To install, first follow the instructions on Page 3

- Initial Set Up Instructions section.

The Initial Set Up Instructions assume that you have decided to install your Mega-Catch
Mosquito Trap on the Stand that is supplied with the Trap.

Alternatively, you may choose to install the Trap on a Mega-Catch Trolley which can be
purchased as an optional extra (see page 7-8, Mega-Catch Trolley section).

Alternatively you may decide to hang the Trap from a tree or a fixed post using a chain, nylon
rope or wire connected to the attachment hole at the top of the Trap. We recommen a height
of around 3 feet (1 meter) from the ground to the top of the Mega-Catch Mosquito Trap.
However, you may need to adjust the Traps height depending on the type of mosquitoes you
are catching.

Your Mega-Catch Mosquito Trap is supplied with a 60-foot (18-meter) low-voltage extension
cord with weatherproof fittings. To avoid the cord posing a tripping hazard or being damaged,
(e.g. by a lawn mower) we recommend that, if possible, it be placed 2-3 inches (50-75 mm)
underground. This can be easily achieved by using a spade which is inserted into the ground
and moved backwards and forwards to create a shallow slit trench into which the cord can
be pushed before the ground is replaced by standing on the top of the slit trench.

FIG 1 - Trap Positioning

Siting of Trap:

For the best performance from your Mega-Catch Mosquito Trap, first determine the source
of the mosquito nuisance (Mosquitoes breed in wet areas like streams, marshland, wooded
areas and gardens). Then use these rules to site the Trap:

Rule 1: Place the Trap between the mosquito source and areas of human activity.

Rule 2: Place the Trap as far away from people and as close to the mosquito source as possible.

(Attract them to the Trap and not to you.)

Rule 3: Place the Trap upwind of the mosquito source but only if you can comply with Rule

1. (Mosquitoes sometimes use the wind to navigate.)

Rule 4: Place the Trap in a predominantly shaded area. (Most mosquitoes avoid direct sunlight.)

Rule 5: Place the Trap in a location protected from rain and strong wind. (Mosquitoes dont

fly in strong winds.)

Rule 6: If severe weather conditions are predicted then store the Trap out of the weather.

NOTE: For optimum performance place the trap in a predominantly shaded area (located between
your dwelling and the source of the mosquitoes) which is protected from rain and wind. (Mosquitoes
do not fly in strong winds or severe weather conditions.)
For maximum stability the 'U' shaped leg at the back of the stand should be pointed in the direction
of prevailing winds. The wire staples supplied with the trap (or a cinder block placed on the back of
the stand) can be used to increase stability.

Mega-Catch Variable Quantity Slow CO2 Gas Release System

Mosquitoes find their prey using a vast array of sensory signals including light, shape, color,
heat, vibration and various chemical compounds produced by humans and other animals. One
of these compounds is carbon dioxide or CO2. Most conventional traps rely on CO2 gas to attract
mosquitoes. They usually achieve this by burning flammable liquids like propane. Carbon dioxide
gas is one by-product of that combustion process.

Mega-Catch Traps on the other hand need no CO

to attract mosquitoes. Using advanced

2

design features and sophisticated electronic components, Mega-Catch Traps exploit a wide
range of sensory signals to attract mosquitoes.

Mega-Catch also offers its own carbon dioxide attractant system using its patented Variable
Quantity Slow CO2 Gas Release System. The latest version of this system is now a standard
feature on all Mega-Catch ULTRA model Traps.

Use of this attractant system is entirely optional i.e. while the system is designed to increase
capture rates it is not essential to the effective operation of the Trap. Even without the system,
or with the system turned off, your Mega-Catch ULTRA Mosquito Trap will catch significant
numbers of mosquitoes and other biting insects.

Conventional Traps which burn propane release CO

gas in a continuous stream as part of the

2

exhaust gases from the propane combustion process. Mega-Catchs Variable Quantity Slow
CO2 Gas Release System is designed to replicate a key element of human respiration by releasing
quantities of pure CO2 gas at an exponentially decaying (negative) rate over fixed intervals to
produce a concentration gradient in the air plume emanating from the lower part of the Trap.
Mosquitoes use this concentration gradient to navigate their way to the Trap.

The Mega-Catch system is able to release more CO2 (and in a cleaner and purer form) than
propane burning traps by using carbon dioxide in the same cylinders as those used by the
beverage industry to aerate (put bubbles into) the likes of beer, softdrinks and sparkling mineral
water. CO2 gas in this form is able to be purchased from hundreds of gas supply outlets
throughout the U.S.A. and elsewhere (see page 13, CO2 Gas Suppliers section).

ATTENTION: DO NOT OPERATE THE ULTRA TRAP INDOORS

10

Connecting the ULTRA to the CO2 Gas Supply

Before attempting to use the Variable Quantity Slow CO2 Gas Release System you must first
follow these instructions (also see figure 3.2 below):

Push gas line firmly into black collet fitting
in panel on rear of Mega Catch unit

Wheel to turn gas flow on / off

Gas Cylinder

Push gas line firmly
into orange collet fitting
on regulator unit

Low pressure
CO2 gas regulator

FIG 3.2 -Connection of trap to CO2 gas cylinder

1. The ULTRA comes with a low-pressure CO

gas regulator and a length of low pressure

2

gas line to connect the Regulator to the Trap.

2. Check to ensure that the O-ring on the Gas Regulator is properly in place and

undamaged. (Note: the gas pressure setting of the Gas Regulator has been set in the
factory and cannot be adjusted. For this reason the knob on the Gas Regulator is
redundant, i.e. turning the knob has no effect on the operation of the Gas Regulator).

3. Attach the Gas Regulator onto the threaded section of the Gas Cylinder and tighten
firmly using a suitable sized wrench. Note: if the threads do not match then contact
your gas supplier (see page 13, CO

Gas Suppliers section).

2

ATTENTION: Do not turn on the CO2 gas supply from the Gas Cylinder until you have
fitted the low-pressure Gas Regulator. Direct contact with liquid CO2 may result in injury.
CO2 Gas Cylinders (empty or full) which do not have a low-pressure Regulator firmly
connected should be securely locked away out of reach of children. We recommend that
CO2 Gas Cylinders be moved around using a Mega-Catch Trolley which has been specially
designed for this purpose.

11

4. Push one end of the gas line firmly into the orange collet fitting on the Gas Regulator
unit. Push the other end of the gas line firmly into the black collet fitting in the panel
on the rear of the Mega-Catch unit (see figure 3.2). Gradually turn on the CO

gas by

2

turning the wheel on the top of the Gas Cylinder in an anti-clockwise direction.

5. Check for gas leaks from the Gas Cylinder, the Regulator and the gas line using a small
quantity of liquid detergent/soap thoroughly stirred in some water (simply brush or pour
this over the items to be checked). A gas leak can be detected by the appearance of
bubbles. If a leak is detected then turn off the CO

gas by turning the wheel on the Gas

2

Cylinder clockwise. Then disconnect the Gas Regulator and check that the O ring seal
is in place and is undamaged and then repeat the process. If there is still a leak from
the Gas Cylinder or the Gas Regulator refer to your gas supplier (see page 13, CO

Gas

2

Supplier section.) or email us ([e-mail]).

6. To remove the gas line simply use two fingers to push the sides of the plastic collet
fitting inwards then, using the other hand, firmly pull the gas line out of the collet
fitting. If the line is damaged replace it. If however the damage is restricted to the end
of the line simply cut out the damaged area. (Note: the collets are the orange fitting
at the Regulator connection and the black fitting at the Trap connection). See figure

3.2.

ATTENTION: BEFORE INSTALLING OR REMOVING THE GAS REGULATOR ALWAYS ENSURE
THE GAS IS TURNED OFF BY TURNING THE ON/OFF WHEEL ON THE GAS CYLINDER
CLOCKWISE.

Operation of Variable Quantity Slow CO2 Gas Release System

You can adjust the quantity of CO2 gas being released from the ULTRA Trap by a simple touch
of the GAS SELECT button on the Programmable Timer. When the power is first turned on the
Trap automatically selects setting # 1 which is the lowest gas usage quantity. The GAS SELECT
button should be touched once to move to the next setting (indicated by the red light glowing
on the setting chosen). Touch the GAS SELECT button for the number of times necessary to
move to the setting # you wish to select.

Remember to reset the setting # after each time the power is switched off.

On setting # 1, a 20lb (9kgs) CO

recommend that the Trap be operated for no more than 8 hours a day at times so as to coincide
with peak mosquito activity. This might be increased to 12 hours a day if you are experiencing
a particularly heavy infestation of mosquitoes.

12

Gas Cylinder can be operated continuously (i.e. 24 hours per

If you operate your Mega-Catch Mosquito Trap in accordance with our recommendation of
no more than 8 hours per day, then you can expect a 20lb (9kgs) CO2 Gas Cylinder to last as
follows:

Gas Select # Approximate Duration

# 1 In excess of 1 year

# 2 125 days

# 3 45 days

# 4 30 days

# 5 22 days

We recommend that you choose setting # 2 or # 3 for normal Trap operation. In preparing for
an outdoor function, you might wish to operate the Trap on setting # 4 or # 5 for a limited
period, e.g. 12 hours per day for 2 or 3 days.

CO2 Gas Suppliers

Mega-Catch Mosquito Traps equipped with the Variable Quantity Slow CO

Mosquito Catching Systems

Your Mega-Catch Mosquito Trap comes complete with a Catch Bag and a Liquid Catch
Container. You may choose to collect mosquitoes using either of these systems.

Our research has shown the Liquid Catch Container system to be more effective. This is because
when the Mega-Catch Mosquito Trap is operated using a Liquid Catch Container, the air
plume emanating from the bottom of the Trap is humidity enriched.

Depending on local temperatures, evaporation may mean that it is necessary to replenish water
in the Liquid Catch Container weekly or even more frequently. The Catch Bag system requires
less frequent attention and therefore may be your preferred mosquito catching system. Smaller
biting insects (eg: no-see-ums) are best caught using the Liquid Catch Container because the
mesh size on the standard Catch Bag may be too large to capture them.

Using the Liquid Catch Container

To prepare your Mega-Catch Mosquito Trap, follow these steps:

1. Ensure that the Trap is switched off by disconnecting the power

(Attention: High-Speed Fan inside the Trap may cause injury if the power is not
disconnected.)

2. Unlock and remove the Lockable Door.

3. Slide the Liquid Catch Container out from beneath the Fan. This container has locating
feet on its base.

4. Fill the container with water until it is approximately two-thirds full. Add 3 or 4 drops
of liquid detergent/soap and stir thoroughly. This breaks the surface tension of the water
ensuring that mosquitoes drown upon capture.

5. Add 3 or 4 teaspoons of a non-diet (sugar-based) soft drink. This duplicates the fructose
content of nectar on which mosquitoes feed.

6. Reinstall the Liquid Catch Container into the Mega-Catch Mosquito Trap. Replace and
lock the Door and remove the Key for child safety. Reconnect power.

7. Before removing the Liquid Catch Container, remember to disconnect the power to your
Mega-Catch Mosquito Trap so that the Fan is not operational. Dispose of the contents
well away from your dwelling so as to not attract ants.

It may be necessary to replenish or replace the water solution in the Liquid Catch Container
at weekly or more frequent intervals to take account of evaporation. This will depend on
relevant climatic conditions.

16

Using the Catch Bag

To prepare your Mega-Catch Mosquito Trap, follow these steps:

1. Ensure that the Trap is switched off by disconnecting the power (Attention: High-

Speed Fan inside the Trap may cause injury if the power is not disconnected.)

2. Unlock and remove the Lockable Door.

3. Reach inside the Trap and stretch the open neck of the Catch Bag around the corners
of the base of the Fan just above the Fan Safety Guard (see figure 5). The Catch Bag
has an elastic neck to facilitate attachment.

4. Replace and lock the Door and remove the Key for child safety. Reconnect power.

5. Before removing the Catch Bag, remember to disconnect the power to your Mega­Catch Mosquito Trap off so that the Fan is not operational. Then pull the drawstring
tight so that any mosquitoes that remain alive cannot escape. Crush the top of the
Catch Bag down on its base to kill any mosquitoes that do remain alive. Dispose of the
contents well away from your dwelling so as not to attract ants.

Mosquitoes collected in the Catch Bag will usually die very quickly without access to
moisture. In cooler climates they may live for a longer period. In times of heavy infestations
of mosquitoes, it may be necessary to empty the Catch Bag on a regular basis in order
to ensure optimum operation of the Trap.

Fitting of External Skirt

Your Mega-Catch Mosquito Trap comes with an External Skirt which fulfils two important
functions. First its color and texture provides a visual attractant for several species of mosquitoes.
Secondly, it acts as a baffle directing the air plume out of the bottom of the Trap.

There are two methods which you can use to fit the Skirt (Method One is the easiest):

U.S. Design Patent No 449,091

FIG 6 - Fitting External Skirt

External Skirt

Hook-and-loop fastening

Method One:

1. Place the Mega-Catch Mosquito Trap on a table or other flat surface.

2. Slide the Skirt on from the top of the Trap (over 2 corners initially) with the elastic band
at the top.

3. The Skirt is properly fitted when the elastic band is seated over the lower horizontal
rib, just below the inlet holes (see figure 6). The opening in the Skirt should be located
at the front of the Trap so as to facilitate removal of the Door without having to remove
the Skirt. The hook-and-loop fastening on this opening should be closed when the Trap
is running.

Method Two:

1. Hang the Mega-Catch Mosquito Trap from the Stand (see Page 3 - Initial Setup
Instructions section - paragraph 11).

2. Slide the Skirt up from the bottom of the Trap (over 2 corners initially) with the elastic
band at the top.

3. The Skirt is properly fitted when the elastic band is seated over the lower horizontal
rib, just below the inlet holes (see figure 6). The opening in the Skirt should be located

18

at the front of the Trap so as to facilitate removal of the Door without having to remove
the Skirt. The hook-and-loop fastening on this opening should be closed when the Trap
is running.

NOTE: Failure to position the skirt correctly will result in a NIL mosquito catch.

The Skirt is not manufactured from a U.V.-resistant material but this will not be an issue if
the Trap is operated in shaded conditions as recommended. The Skirt can be reversed should
one side begin to fade from exposure to U.V. light. The Skirt is a consumable item and
replacements can be obtained from your Authorized Distributor.

Care of Your Trap

Your Mega-Catch Mosquito Trap requires very little maintenance. The Catch Bag and Liquid
Catch Container should be cleaned and washed when required.

Heavy catches of mosquitoes may result in a build-up of material in the internal casing and
blade tips of the Fan. There may also be a build-up of material on the Fan Safety Guard. If this
happens use the following cleaning technique:

1. Ensure the power to your Mega-Catch Mosquito Trap is disconnected. (Attention:

High-Speed Fan inside the Trap may cause injury if the power is not disconnected.)

2. To remove the Trap from the Stand, tip the Trap on its side and slide it off the hook.

3. Unlock and remove the Lockable Door. Then lay the Trap on its side with the Door
opening being face up.

4. Reach inside the Trap and remove the Fan Safety Guard (attached to base of Fan) by
turning it counterclockwise (see figure 6).

5. Using a small sponge (1 x 1 x 3 or 25mm x 25mm x 75mm) and warm soapy water,
reach into the Trap and carefully clean the inside casing of the Fan and the Fan Blades.
When dry, spray the inside fan housing and the tips of the fan blades with a coat of
TEFLON-based dry lubricant spray.

6. Ensure that water is not allowed to enter into the Fan Motor. Never hose water into
the Fan.

7. Clean and then replace the Fan Safety Guard.

8. Leave the Trap to dry for at least 24 hours before reinstalling it on the Stand and
recommencing operation.

The casing of your Mega-Catch Mosquito Trap is made from polypropylene, which is extremely
strong and durable. Its appearance is best maintained by a plastic protector of the type used
on plastic car fenders. Do not use wax.

In order to prolong the life of your Mega-Catch Mosquito Trap store it and the Mega-Catch
Stand in a dry place when not in operation. Your Mega-Catch Mosquito Trap should be
serviced at the end of each season (see Page 23 - Maintenance and Repair of Your Trap
section).

Replacement of U.V. Blub

The U.V. Bulb is a consumable item and replacements can be obtained from your Authorized
Distributor. To install a new U.V. Bulb refer to Page 23 - Maintenance and Repair of Your
Trap section.

Mega-Catch Octenol Fragrance Strip

Some, but not all, mosquito species are attracted to minute quantities of a chemical called
octenol (1-OCTEN-3-OL). Each Mega-Catch Mosquito Trap comes with a Mega-Catch
Octenol Fragrance Strip.Use of this fragrance strip is entirely optional.

To install or replace the Octenol Fragrance Strip:

1. Ensure the power to your Mega-Catch Mosquito Trap is disconnected.

2. Unlock and remove the Lockable Door.

3. Remove the Mega-Catch Octenol Fragrance Strip from its pouch and be careful not
to touch the exposed holes on its surface. Place the strip inside the Trap in the position
shown in figure 8 below. Replace and lock the Door and remove the Key for child safety.

Reconnect power.

Wash your hands after this procedure has been completed.

Mega-Catch Octenol Fragrance Strips should be effective for up to 30 days depending on
weather conditions. Mega-Catch Octenol Fragrance Strips are a consumable item and
replacements can be obtained from your Authorized Distributor.

NOTE: Octenol can improve the rate of capture of some mosquito species. Other species [e.g.
the Asian Tiger Mosquito], may not be attracted - or even repelled- by octenol. You should
determine what is best in your area by experimenting without the Mega-Catch Octenol
Fragrance Strip in place.

ATTENTION: Keep Mega-Catch Octenol Fragrance Strips out of reach of children. Read
directions and Important Safety Instructions carefully before use.

Optional Accessories

1. Battery Terminal Power Cable

The Mega-Catch Mosquito Trap can be operated using a 12-volt car battery as a power source.
Your Authorized Distributor can supply a factory-approved Power Supply Cable complete with
positive and negative alligator clips.

NOTE: Failure to connect the red positive + connector to the positive battery terminal and
the black negative  to the negative battery terminal can result in major damage to your Mega­Catch Mosquito Trap and may void your warranty.

2.

Cigarette Lighter/Car Accessory Terminal Cable

The Mega-Catch Mosquito Trap can be operated from your vehicles accessory terminal using
the factory-approved Accessory Cable. Your Authorized Distributor can supply a factory­approved Accessory Cable.

NOTE: Failure to use only the factory-supplied Cable could result in damage to your Mega­Catch Mosquito Trap and may void your warranty.

22

Maintenance and Repair of Your Trap

Opening the two halves of the Mega-Catch Mosquito Trap will be necessary for the following
purposes:

 Replacement of U.V. Bulb (The U.V. Bulb should last for approximately two mosquito

seasons, but, as with all light bulbs, life expectancy is variable depending on actual
usage and climate.)

 Annual service (At the end of each season, the Internal Plates, heated reflective surface

and Fan should be cleaned using warm soapy water and allowed to dry thoroughly.)

 Battery removal (The Programmable Timer contains a Nickel-Cadmium Battery. This

must be disposed of correctly when the Trap reaches the end of its life.)

Opening the Trap (refer to figure 9.1):

ATTENTION: Always disconnect the power to your Mega-Catch Mosquito Trap before
opening the Trap.

The two halves of the Trap are held together with 12 stainless-steel screws and nuts - six
facing one way and six the other way.

Place the Trap on a table ensuring the Programmable Timer is on the side facing down. Remove
the six screws facing toward you using a hex-head screwdriver.

Then turn the Trap over (so that it is "timer-side" up) and remove the remaining six screws and
nuts.

Then lift the top half of the Trap away from the bottom half as if it was hinged at the top. The
top half should now be "timer-side" down on the table and still connected to the bottom half
by electrical cables.

The Top Plate holds the Mega-Catch Control Box (upperside of Top Plate) and the U.V. Bulb
and holders (underside of Top Plate). (NOTE: the Mega-Catch Control Box is a sealed unit
and must not be opened.)

The Bottom Plate holds the heated reflective surface (upperside of Bottom Plate) and the Fan
(underside of Bottom Plate).

FIG. 9.2  Replacement of U.V. bulb

Replacement of U.V. Bulb (refer to figure 9.2):

Remove the U.V. Bulb by twisting the tube gently until it is able to be removed. Then slot a
new U.V. Bulb into the connector ends and twist the tube gently until it is firmly in position.

Reinstallation of Plates:

You should not have any reason to remove the plates from the Trap. If however you do, merely
slot the plates back into the ribs so that the Control Box is on the upper-side of the Top Plate
and the Fan is on the under-side of the Bottom Plate. There are arrows on each plate that
points to the back of the Trap (i.e. the half that does not contain the Timer) when the plates
have been properly installed.

Connection of Wires:

You should not have any reason to remove any of the electrical connections except as part
of the battery disposal process (see Page 26 - Removal of Timer section). All electrical
connections are by push-in pin connectors. Provided these are not forced it is not possible to
plug any connector into the wrong connector hole.

There are three connector holes on the underside of the Top Plate. The two smaller two-pin
connector holes are for the Fan and Heater Cables. These two connections are interchangeable
so it doesnt matter which of these two connector holes the Fan and Heater are plugged into.
The third connection on the underside of the Top Plate is a three-pin hole and fits only the
U.V. Bulb Connection Cable. The connection holes into the Control Box on the upperside of the
Top Plate are all different sizes and fit the remaining cables.

Re-assembly of Trap:

With the Top and Bottom Plates in place replace the "timer-side" or top half of the Trap ensuring
that each plate slots into the locating ribs. The 12 screw holes should now be aligned for
replacement of the screws and nuts. Hold the nuts into the pre-formed hexagonal holes and
carefully screw in the screws.

(NOTE: Do not overtighten the screws. This could cause the nuts to rotate and damage the
pre-formed hexagonal fittings in the plastic housing.)

25

Removal of Timer

The Mega-Catch Mosquito Trap contains one Nickel-Cadmium Battery, which is used to
energize the Programmable Timer. This battery is fitted in a sealed compartment at the rear
of the Timer Unit. This battery must be recycled or disposed of properly.

To Remove the Timer Unit (refer to figure 9.3):

Having opened up the two halves of the Trap:

1. Disconnect the cables from the Timer to the Mega-Catch Control Box by pulling the
Timer Cable Pin from the Control Box

2. Using either your fingers or a screwdriver, lift up the two locating arms at the top and
bottom of the Timer and then push the Timer Unit out from the inside of the Trap.

Disposal of Timer

It is illegal in many states and environmentally undesirable to dispose of the Timer Unit
containing the battery in municipal trash. A fee has been paid to the Rechargeable Battery
Recycling Corporation (RBRC) to collect these batteries and recycle them rather than incinerate
or bury them. For information on our battery recycling program, call our toll-free consumer
assistance number 1-800-231-9786 or call RBRC at 1-800-822-8837 for instructions on proper
disposal.

Frequently Asked Questions

1. Will my Mega-Catch Mosquito Trap permanently eliminate mosquitos in the area?

No. There is no single silver-bullet to eliminate mosquitos. The best you can do is devise an
effective mosquito management plan for your area, using the best available control strategies,
including one or more Mega-Catch Mosquito Traps.

2. How often do I need to operate my Mega-Catch Mosquito Trap?

Before using your Mega-Catch Mosquito Trap note the time of day when mosquito activity
is greatest. If, for example, this is in the morning and the evening, then you should set the Trap
(using the Programmable Timer) to operate at these times. Where your mosquito problem
involves night time biters, we recommend operation of the Trap between 7pm and 11pm and
4am and 8am. If mosquito activity is all day, then you may need to operate the Trap 24 hours
per day until the mosquito population declines.

3. Is the Mega-Catch Mosquito Trap harmful to me or my pets?

No. The Mega-Catch ULTRA Mosquito Trap can be used outside around humans and pets
provided it is operated in accordance with the instructions in this operation manual. Ensure
you read the Important Safety Instructions at the start of this operation manual. Do not operate
the ULTRA Trap indoors.

4. How many traps should I buy for around my house?

This depends on the size of your property. Generally we recommend one or two Traps depending
on the number and location of mosquito breeding areas on your property. A Mega-Catch
ULTRA Mosquito Trap can, in favorable weather conditions, attract mosquitoes from up to 150
feet away.

5. Will Mega-Catch Mosquito Traps catch biting flies?

The Mega-Catch ULTRA Mosquito Trap will catch sandflies, black flies and biting midges (no­see-ums) and some other biting insects.

6. Can I stop my Mega-Catch Mosquito Trap from catching moths?

The Mega-Catch ULTRA Mosquito Trap incorporates a low-intensity U.V. Bulb that emits light
at a frequency our research has shown to attract certain mosquito species. Unfortunately it
can also attract small quantities of non-target species like moths. If this is a problem, the U.V.
Bulb can be switched off by touching the U.V. Tube button on the Programmable Timer.

27

Problem Solving

If your Mega-Catch Mosquito Trap fails to operate:

 Check that the Power Cable is properly connected to both the Trap and the mains, and

that the power is switched on.

 Check that the power cable has not been damaged, e.g. by a lawn mower or animals

(squirrels, dogs or racoons).

 Check that the Programmable Timer is set to the "ON" position.

 Check that the Programmable Timer, if set to AUTO, is set to operate at the time you

are checking its operation.

If these steps fail then email us at [e-mail] - or call the Service Centre number
shown on the separate Warranty Certificate.

If the lights in the Mega-Catch Mosquito Trap come on but the Fan fails to operate:

 Check whether there has been a build up of material in the Fan and/or Fan Safety Guard

which is preventing the Fan blade from turning (Refer to Page 19 - Care of Your Trap
section).

If these steps fail then email us at [e-mail] - or call the Service Centre number
shown on the separate Warranty Certificate.

NOTE: Do not attempt to access the internal electronic components of your Mega-Catch
Mosquito Trap. Opening of sealed units will void your warranty.
