Bifen IT can be sprayed 3 feet up the side of the house, and 3 feet into the soil all the way around the perimteter foundation of the home. When treating for fleas, you will need to apply under decks, under trees, in places where leaves or other yard debris accumulates or areas where dense shrubbery exists. There is little need to spray open, sunny areas, dry and dusty areas or hard surfaces such as patios or driveways as fleas will not be able to develop in those areas. When treating for noseeums, you want to focus on treating those same areas, along with the understands of tree canopies, interior of shrubs and bushes, and damp areas in your lawn.
