How to use Termidor Foam on Carpenter Ants in my ceiling
For a couple of weeks, I have seen residue of something in my ceiling. Turns out it's carpenter ants- I have found a few dead on the floor and seen 2 or 3 climbing up the wall to a gap between the drywall and the molding. Upon looking outside, there is a small hole in my roof (shingles) at the very corner that probably made it easy for them to get in without even making any holes. Could I spray the foam into the hole in the roof, or should I drill holes from the inside drywall? I can't tell if they are in the insulation in the roof, or in the insulation of the exterior wall of the house- but my exterior walls are brick.
Answer:
Termidor Foam will treat for carpenter ants if injected into the bored holes. You will need to drill into the infested area and apply the foam. Termidor Foam expands rapidly creating a dry foam that can be applied in the voids, harborages, galleries, and nests where insects are found. The foam generated has an expansion ratio of 30:1. In about 5 seconds 1 oz. of product becomes approximately 1 quart of foam.
