I found a product(expensive but very very very thorough)that I use for my home and for my RV (parked at home). It is TERMiDOR, the same product used by termite companies to "bait' wood and kill entire termite colonies. I located this at a "Do It Yourself" Pest control center. I have been using it every six months for 18 months and have NO ants, fireants, carpenter and and insects in general around the home and RV. Works by having ants carry product to colony and killing all. Copied this from their site.
1 Termidor SC 20 oz. (Makes 12- 24 gallons ) 100% termite-free in 3 months . Termidor SC is a non repellent for ants and carpenter ants. Outside use only. (Web Only) about $58.
Please research use around pets, I have no pets.
