Greg from United States Iowa City Iowa writes,

How often do I need to spray around the perimeter of my house with Termidor for carpenter ants?

I have your two kinds of bait and wondering what else to do to prevent carpenter ants from coming back. Your advice and products worked great last year. Just trying to prevent and maintain this year.


We are pleased to hear that the advice and products recommended to you were effective for your treatment. Termidor SC can be applied once (every six months) topically on the exterior perimeter of the house for treating carpenter ants. Please let us know if you need anything else.
