I have Carpenter ant damage at my house where an old deck meets the house. How would you recommend getting rid of them?
If you have damage you should be seeing ants. And if you’re seeing ants, trailing them to the nest would be easy and suggested. In all cases like this the first thing you need to do is dust with DRIONE. You’ll see this listed in our CARPENTER ANT CONTROL ARTICLE. It will provide quick control since it penetrates all spaces and voids effectively. I suggest you watch the video as this demonstrates why it’s so effective to use for spaces.
I also recommend spraying the foundation with some TERMIDOR to make sure you have a barrier in place that will get any stragglers or other nests you may have missed.
