The invasion of Carpenter Ants has begun. Please call our office and set up a Free Inspectgion.People tell us they sprayed for Carpenter Ants every year and they go away.But now this year they aren’t going away. It sounds like you might have a nest within the structure. Once a Queen starts a satelite colony inside the structure it takes about 3 years for the colony to mature. Each year the size of the colony increases and the visable sitings of Carpenter Ants increase as well. Most people tell me the same story, I had a few ants I sprayed and they went away. The following year the same, and then by the 3rd and 4th year the have to call. Spraying yourself could make the problem worse.Again best thing is to have a Nature’s Way Pest Control Technician provide a Free Inspection. Thanks!
