Phantom Termiticide Insecticide has a residual of at least 4 weeks. If you were to reapply before that, that would be over-treating and would not allow the product to work properly. It could also help build resistance to it, where it would work less and less.
Phantom is labeled for use indoors on cracks and crevices. Outdoor applications are limited to spot and crack and crevice treatments around door frames, window frames, eaves, attic vents, and holes where utilities enter into the structure not out in the yard. Please be sure to review the product label for more information and complete application instructions. Also, please take a moment to review our Termite Guides for helpful tips on eradicating this pest.
Phantom Termiticide Insecticide is a non-repellent but could become a repellent if applied too heavily.
