You can get rid of carpenter ants by using insecticides and sprays in different forms such as baits, liquid concentrates, foams and dusts.


  • Non-repellent insecticides – These are used as perimeter sprays.
  • Baits – They are applied on carpenter ants trails.
  • Dusts – They are used in galleries and voids.
  • Foams – They are used in galleries and voids.

Inspection – The first step to controlling ants is through inspection. You should carry out some inspection to determine if the ants are inside the house or outside the house, or if you have a satellite colony or a colony inside your house.

Determine control measure – After completing the inspection, identify foraging trails and nest locations. Now, decide which control measure to use.

Prevention – Lastly, try as much as you can to prevent invasion. You can do this by ant-proofing your yard and home by clearing your lumber piles, rotting trees as well as fixing plumbing leaks.

Baiting procedures for ants in recessed areas and foraging ants

Carpenter ant baits should be used immediately after inspection. The ant baits are made to attract ants. On the other hand, foraging carpenter ants takes the bait back to the colony and thus killing the whole colony.

Things to note
Never use repellant insecticides together with baits, because repellants drive carpenter insects away, and thus they may render the baits useless. But you can use non-repellant insecticides where the baits are placed.

It is also crucial to get rid of other competing sources of food such as pet food and bread crumbs, because they may interfere with the bait.

Don’t use liquid insecticides on a wall void. If you want to treat wall voids and other hidden spots where ants stay, drilling a number of small 1/8 inch holes, and then pour a residual insecticide dust on these areas.
