We found carpenter ants digging in our second story deck. We called a pest control company that sprayed Termidor around the perimeter of our house and all over the second story deck. The skies opened and drenched everything about an hour later. The ants disappeared within a day or two. Two weeks later we are seeing ants inside our sunroom (we did not have them there before. The sunroom is built on stilts with a lattice base. The pest control company sprayed the base of the lattice but not the foundation poles or under the sunroom (which includes the actual foundation for the house). We purchased Maxforce gel bait and Advance bait and plan on putting them out once they arrive. Will the Termidor on the deck last? I've thrown several ants onto the deck? What else can I do? I really thought the Termidor would take care of everything. Should we also be spraying our lawn? I've seen winged ants outside near our house.
Termidor SC is a great exterior product for ants including carpenter ants. It will last for six months as a topical outdoor application but can take some time to fully eradicate as the ants carry it and transfer to other colony members. You will be able to get rid of Carpenter Ants more effectively if you can locate where they are coming from. They are the most active at night between 10AM-4AM. We do recommend treating with the Maxforce FC Carpenter Ant Bait and the Advance Carpenter Ant Bait. These baits will be extremely effective. The granules should be applied when dry outside and you are not expecting any rainfall within 24 hours of application. The bait gel can be applied directly to indoor cracks and crevices once every two weeks. Carpenter Ant Control Article
