Hi - Your site is a great resource. Wondering if you have an opinion on a carpenter ant problem we're having. We live in Connecticut in a 7-yr-old house and have a sudden, bad interior carpenter ant problem. It started 6 weeks ago, almost instantly, with about 100 ants in our kitchen over one weekend (starting with a rotting peach on counter). We hired our local, reputable exterminator. We used this local company before - when we lived in our last house - and they successfully treated multiple problems (ants, carpenter bees and mice). We hired them this time for the flat rate carpenter-ant service ($300) where they will treat the ant problem until resolved or as needed until the end of the year. The exterminator has been to the house 4 times now in 4 weeks doing various treatments - including pressurized vapor treatments under the siding, perimeter ground treatments around exterior of house (liquid and granular) and a minor gel spot treatment in kitchen area. We have also done regular whole-lawn treatments on our own and we applied our own drione dust behind cabinets in kitchen. But the problem is persistent. We vacuum up 2-10+ ants per day in and around our kitchen, every day, in the month since we've started the treatments. The exterminator cannot find the nest and we can't help them find it either. We've done exhaustive searches in our house, examining everything we can - the whole kitchen, basement and attic, we've even pulled up decking to search under porches and pulled down insulation to search along foundation, and drilled holes behind some kitchen cabinets to look for ant nests or sources.
The exterminator's best guess is that the ants are coming from an outside nest, but I think they are coming from a nest in the house (b/c of the steady, daily flow of ants, and b/c we can't find any ant concentration anywhere around our yard).
What could we or our exterminator be missing? What can we do to find the nest or to get rid of the nest without finding it?
Thanks in advance for your input!
