How to Get Rid of Carpenter Ants
Carpenter Ant Treatment Guide
There Are Multiple Treatment Method Options
After you have located the areas that have been infested by carpenter ants you will need to select the treatment method that best fits your needs. There is a wide variety of carpenter ant control products and methods available due to to the wide array of areas that carpenter ants can infest.
Indoor Baiting and Spraying
If you see the carpenter ants and perhaps even some debris they have left behind but you cannot access the nest directly, we recommend you use a combination of carpenter ant bait and a non-repellent spray to eliminate the colony. We recommend using three key products to effectively get rid of ants:
Indoor Carpenter Ant Bait
You should place bait in areas where carpenter ant activity has been noticed. It is important to avoid purposefully putting the bait in the middle of an ant trail or on to the ants themselves. This will make the ants avoid the bait and make the baiting ineffective. Instead put the bait near ant activity or next to ant trails. To help keep ant bait fresh and off of surfaces we recommend placing the bait in the bait plate stations provided in the kit. Some examples of places where the bait can be placed are:
Indoor Carpenter Ant Spray
We recommend using a non-repellent carpenter ant spray to supplement baiting. We make this recommendation for two reasons:
Using the included straw applicator, apply the spray directly into cracks and crevices along baseboards, under appliances, around door frames, window frames and in areas where utilities (cables, pipes, wires) enter into the structure and other areas where ants have been entering your structure.
Direct Nest Treatment
If you are able to find the actual carpenter ant nest, you can treat it directly to eliminate the nest quickly. There are a couple of ways to treat the area. If it is in a wall void you can choose use foam or ant dust to fill the void thoroughly. If the nest is located in, say, a wood beam, you can choose to foam or dust that area that as well.
Wall Void Treatment
If the nest is located in a wall void, you can choose to open up the wall by cutting out pieces of sheetrock, or you can choose to drill holes through the sheetrock into the infested areas to apply the chosen product. If drilling holes into the wall or opening the wall is not possible or not desirable, you will want to follow method 1 for eliminating your carpenter ant infestation.
Foams:You can choose to purchase ready to use foam products that come with a small flexible hose and a nozzle to help apply the product to the correct areas. For larger jobs, you can choose to purchase a non-repellent concentrate spray, a foaming agent and a foaming device to apply the foam. Non-repellent foams do work a little bit slower than dusts but they offer the benefit of expanding in the void to cover more area.
Dusts:You should choose a dust that is labeled for carpenter ant control. You will need a hand duster to apply the dust to the void or to the gallery if the nest is located in a piece of wood. Dusts do tend to kill the ants a bit faster than foaming but you may need to drill more holes or open the wall a bit more to make sure you are getting even coverage.

Outdoor Sanitation and Preparation
If you find that you have ants crawling around the exterior of your home or structure you should also consider treating outdoors to avoid a new infestation indoors. Just like treating indoors, you must eliminate or change the environment around your home which made the carpenter ants find your property attractive to start with. Sanitation means more than cleaning up food that has been left out or sweeping up certain areas. Sanitation for carpenter ant control means altering or eliminating the things that carpenter ants need to live. Pests of all kinds require three essential needs to exist on your property:
Outdoor Baiting and Spraying
Carpenter ants can nest in a wide variety of places outdoor so the treatment that is needed will vary. We will outline the most common treatment methods but if you find yourself facing a unique treatment area, please contact our customer care team to speak to an expert.
Use Outdoor Carpenter Ant Spray
You will need a hand pump sprayer or a backpack sprayer to apply Termidor. You will mix 0.8 fl oz of product with each gallon of water. Most folks will need 1-2 gallons of finished solution to complete the perimeter application. You will need to apply the Termidor solution one ft up the foundation and one foot out onto the ground to build a barrier. You can also apply the solution around window frames, door frames, places where cables, pipes or wires enter the structure and any other place where you have noticed ants crawling or trailing on the structure. You cannot spray Termidor out in the yard as a broadcast spray, and you must limit applications to once every 6 months.
You should note that Termidor is formulated to have a slow kill time to allow the ants to spread the product around the colony, and it can take several weeks to see the full results.
Use Outdoor Carpenter Ant Bait
If the ants are further away from your home or spraying is not desirable, we would recommend using a carpenter ant bait granule. Carpenter ant bait granules can be broadcast over wide areas but studies show the baits work best if put in small teaspoon sized mounds near the areas where activity has been noticed. Carpenter ants usually forage during the night so it is recommended that you apply the bait just before sunset on a night when rain is not expected. As the carpenters ants forage they will pick up the bait and take it back to feed the colony. Over a few weeks, the colony will be eliminated.
