We have recently found several carpenter ants in our house. We live in Saskatchewan, Canada and it is currently very cold outside. I recently purchased an old barn beam from the US to use as a shelf in our house. Yesterday I noticed a carpenter ant crawling out of a hole in the beam! We very quickly removed the beam from the house and I am fairly sure that the beam was the source of the ants. I am now wondering if they will have nested in our house. Will removing the old wood remove the problem or do we need to be concerned about a nest in the house?
The beam was in the house for approximately 2 months. In that time we have seen a total of 5 ants (3 with wings, 2 without). The house is new and there are no moisture issues, however we do have spray foam insulation in the floor joists between the basement wall and main floor.
Thanks for your help!
