Will Hi-Yield 38-Plus work for cockroaches?

what is concentration for cockroaches


Hi Yield 38 Plus can be used outdoors only for cockroaches (do not use indoors). According to the product label: Mix 1.6 fl Oz. (3 1/4 Tablespoons) of this product per 1 gallon of spray solution to make a 0.5% spray emulsion. 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. If mulch or debris is present, a higher volume application rate may be needed to ensure adequate coverage. Note: 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. If you need to treat indoors we recommend our Roach Control Kit #2. This kit comes with all of the necessary products needed to treat an indoor infestation and enough product to use outdoors to stop new roaches from moving in.
