ENVIRONMENTAL HAZARDS: Do not apply to treated, finished  
drinking water reservoirs or drinking water receptacles, 
when the water is intended for human consumption.
FIRST AID
Have the product container or label with you when calling a 
poison control center or doctor, or going for treatment. You  
may also contact the National Pesticide Information Center at 
1-800-858-7378 for emergency medical treatment information.

    of water for 15-20 minutes. 
    Call a poison control center 
or  
    doctor for treatment advice. 
If Inhaled:   Move person to fresh air. 
    If person is not breathing, call 911

DIRECTIONS FOR USE
It is a violation of Federal Law to use this product in a manner 
inconsistent with its labeling. 
BONIDE® Mosquito Beater® WSP is a highly selective 
microbial insecticide, effective against mosquito larvae in 
standing water. The active ingredient, Bacillus thuringiensis 
subsp. israelensis (or Bti) kills mosquito larvae upon 
ingesting. BONIDE® Mosquito Beater® WSP will not harm 
fish, amphibians or other [beneficial] aquatic organisms.
BONIDE® Mosquito Beater® WSP can be applied to 
any containerized water site except, 1) New York State 
Waters, 2) treated, finished water reservoirs or drinking 
water receptacles, when the water is intended for human 
consumption. Use BONIDE® Mosquito Beater® WSP  
to control mosquito larvae in livestock watering troughs, 
containerized water gardens, flower pots, rain barrels, roof 
gutters, bird baths, tree holes, unused swimming pools or 
spas, discarded automobile tires, and any other containerized 
location around the home or other buildings where water 
can collect [and form a breeding ground for mosquitoes] and 
remain for extended periods. 
BONIDE® Mosquito Beater® WSP is provided in a watersoluble pouch to be placed directly on the surface of the 
water to be treated. The pouch will float on the water surface 
and dissolve within a few minutes, releasing granules coated 
with Bti. [These granules then slowly release the long-term 
Bti larvicide.]
HOW TO APPLY: 
[APPLICATION RATE] 1 pouch (0.2 oz.) will treat up to 50 
sq. ft. of water surface. [An area approximately 7’ x 7’] When 
using multiple pouches to treat larger areas, distribute the 
pouches uniformly on the water surface to ensure adequate 
dispersion of the granules. Lower rate (1 pouch/50 sq. ft.) 
can be used in clear water, against low larval infestations or 
young larvae (from egg hatch to mid-third instar). When larger 
larvae (late third
 instar to early fourth instar) predominate, 
larval populations are high, or water is polluted and/or algae 
are prevalent, use the higher rate of 2 pouches per 50 sq. ft.
The following table can be used as a guide for determining 
how much BONIDE® Mosquito Beater® WSP to use in a 
particular situation. Application rates for areas smaller than 
50 sq. ft. are listed after the table.

SMALL AREA APPLICATION: To apply this product to small, 
specific areas such as bird baths, tree holes, flower pots, 
etc...trim off a corner of the pouch and sprinkle granules onto 
the area to be treated, at the following rates:
AREA TO BE TREATED
1 to 12½ sq. ft. 
12½ to 25 sq. ft. 
25 to 37½ sq. ft. 
QUANTITY TO USE
¼ of a pouch 
½ of a pouch 
¾ of a pouch
Application can be repeated every 7 to 14 days, as needed, 
if environmental conditions favor continuous breeding of 
mosquitoes. Longer periods of mosquito suppression may 
result where sufficient numbers of aquatic parasites or 
predators of mosquito larvae are present, since these are 
not affected by BONIDE® Mosquito Beater® WSP and 
contribute to overall reduction in mosquito populations.
