Prudence from Fallbrook,ca writes,

Can this product be applied and will it leave a residual if sprayed on concrete or brick window sills?


Hi-Yield 38-Plus Insect Control is labeled to be be applied at entry points of the structure such as window frames, doorways, porches, patios and foundation. plication rate may be needed to ensure adequate coverage. Residual control will vary depending on exposure of the treated area to weathering conditions (temperature, sunlight, moisture). Retreat on a monthly schedule while Insects are likely to be active.

For Outdoor Perimeter Applications: Spray a 6 to 8 foot wide band of soil around the perimeter of the house. Treat the foundation wall to a height of 2 to 3 feet. Use a spray volume of 2 to 10 gallons of 0.5% emulsion per 1,000 square feet.
