I live in upstate New York. Every year we start seeing carpenter ants crawling around the living room. We usually see about 5 or so a day in the living room around this time of year and then more like 15 or so a day around the rest of the house towards April and worse through the summer.
I believe there are nests in the house somewhere. I think there is probably one in the cavities around a window in the living room as my wife had seen one or two go behind the trim under the sill and disappear. I have gone into the basement and seen ants crawling in the space where the tongue and groove subfloor don't quite meet and I think they are getting through the entire distance of the house this way. The 5/16" thick oak flooring upstairs does not quite meet the baseboard in some places and we have also seen ants come from the gaps.
I have two trees out front that are infested with them and need to come down this summer. My house is bordered by deep woods on two sides and has had pine tree branches laying on the roof when I bought it. I have since did some major branch trimming.
I know these things have satellite nests but I don't believe the nest in the house is a satellite because of how early in the year I see them, I think its the real deal. In the past I have tried baiting with every bait concoction I have read about, spraying the outside foundation with a perimeter spray and spraying nooks with drione dust. It seemed like the drione dust just ticked them off and forced more into the house.
Anyone have any success with locating and getting rid of these pests?
