CAUTION
Chemical can blow and drift. Apply on calm days. Otherwise,
sprayed chemical can drift up to 150 meters, causing unintentional
contact.
A full tank of Yard Shield mixture will cover 15,000 square feet.
Aim blower at the ground, bushes, shrubs, hard-to-reach places, and
mosquito breeding grounds. For best results, position blower 3 - 6 feet
from area to be treated and use blower at wide open throttle.
Progress at a normal walking pace, sweeping blower in a side to side
motion, always overlapping passes. Avoid walking directly into spray.
Apply until surfaces are wet but not dripping. People and pets may
safely return to area after application is dry.
Yard Shield will remain effective for up to 3 weeks, as long as surfaces
remain dry. Precipitation will wash Yard Shield away.
