I am in NC near charlotte. I found a week ago, carpenter ants on a few trees outside and today I noticed termite tubes and sawdust on a fence right beside my home. We had bait stations for termites. I checked them 2 months ago and they were fine and I checked again today and the bait was gone. I put out boric acid on the fence and where the bait stations were. Should I do anything else??? I have not seen anything inside the home yet.
Forget the bait stations for now. The simplest and most direct approach that will solve the problem immediately will be to treat the fence with some TERMIDOR. If you read up on how it works in our TERMITE CONTROL ARTICLE, you’ll learn this active is ideal for termites and can be used to protect homes, fences, trees, etc. And it handles CARPENTER ANTS too so you’ll get the added advantage of covering all the pests you’ve seen around the fence with one spray.
