How do you kill outdoor ants, common ants and fire ants using Bifen IT?
Bifen IT is an excellent insecticide and is labeled for ants, including fire ants.
The best control will be achieved by using broadcast treatments in combination with mound drenches. This will control present colonies along with foraging workers and newly mated fly-in queens. It is critical either to use high volume treatments or to irrigate prior to application if the soil is dry. Apply 1 fl. oz. per 1,000 square feet when using broadcast treatments. For mound drenches, dilute 1 teaspoon of Bifen I/T
of water and use 1 to 2 gallons of finished dilution using sufficient force to penetrate the top and allow dilution to flood ant channels. Treat a four-foot diameter around each ant mound. Application should be made in late evening or early morning when it is cooler (65-80° when insects are most active. NOTE: A spray rig calibrated to apply 1 fluid oz. per 1,000 square feet of Bifen I/T
in 5 gallons per 1,000 square feet contains the equivalent
dilution (1 teaspoon per gallon) required for fire ant mound drenches in the spray tank.
For other ants, we would recommend a perimeter treatment around your home. You will use 1 fl. oz. per gallon of water.
Please let us know if you have any additional questions.
