Bifen IT can be sprayed around the perimeter of your home. It can also be sprayed around window frames, door frames, utility entry points as well as on ornamental plants, shrubs, and trees. As the pests come in contact with the treated areas they will make contact with the residual that will eventually affect their central nervous system and succumb to the effect of the chemical. We recommend watching our video on Outdoor Perimeter Pest Control Treatment for a better example of the areas that need to be treated.
