How to Get Rid of Carpenter Ants in Walls


When a carpenter ant nest is located in a
wall void, you’ll need to open up the wall before applying a foam or dust product. There
are two ways to open a wall for treatment. The first way is to cut away pieces of sheetrock.
The second way is to drill holes through the sheetrock into the infested areas. Holes should
be ⅛” inch wide and extend 2 to 6 feet on either side of where the ants are entering.
This will increase your chances of directly contacting the nest and queen. For small areas, choose a ready-to-use foam
product that comes with a small flexible hose and nozzle for quick and easy application.
For larger jobs, a foaming agent AND foaming device will be needed to apply the foam. Non-repellent
foams work more slowly than dusts, but offer the benefit of expanding in the void to cover
a larger area. An additional benefit of the non-repellent foams is how the active ingredient
is spread through social interaction to eliminate the entire colony. For dust treatments, be sure to choose a product
labeled for carpenter ant control. You will need a hand duster to apply the dust. Insert
the tip of the filled duster into the drilled holes and apply evenly. Dust will cause the
ants to die faster than with foam, but you may need to drill more holes or open the wall
more to make sure you are getting even coverage. And it’s that easy with the expert help
