How To Track Down And Kill A Carpenter Ant Nest In Your Attic

Late spring is the time carpenter ants emerge from their nests and start devouring wood. If they get into your home to eat, they can destroy joist boards, rafters, and other pieces of wood throughout your house. The best way to get rid of the carpenter ants is to find their nest and destroy it. If you are a homeowner suffering through a carpenter ant invasion this spring, here is how you can locate the nest and destroy it.

You Will Need:

  • Flashlight
  • Stethoscope
  • Drill
  • Pesticides

Follow the Carpenter Ants

Carpenters ants like to spread out during the day as they forage for food and it is extremely hard to tell which direction the nest might be by just watching them walk back and forth. You have to wait until evening to really tell where the ants go when the work day is done. Ants will travel together as they march back to the nest and this is the time you should follow them to see where they go.

As evening falls, walk around the exterior of your home to see where the ants are gathering. Take a flashlight with you if it's getting too dark for you to see well. The ants may climb up trees and you might think that this is where they live, but they once they walk up a tree, they can then go onto an electrical or cable wire that takes them right into your house or attic. Make a note of where they are entering your attic from the wire and then go inside to where they came into your house.

Locating Nest

The ants might be hard to spot in your attic, but you will be able to hear them with the help of a nurse's stethoscope. Crawl to the edges of the rafters and start placing the stethoscope on the boards. Work your way around the attic until you hear the distinctive sound of the carpenter ants moving around and chewing on the wood.

Killing the Nest

Drill little holes in the wood just big enough to fit the tip of the hose that fits onto the spray nozzle of a can of pesticide so you can apply the material in tight places. Attach the hose to the nozzle and stick the end of it into the hole you made in the wood. Spray the pesticide into the hole until the nest is saturated—you'll see the pesticide coming back out of the hole when the space for the nest in the wood has been filled up. Filling the nest with pesticide should only take a few seconds. Make sure the pesticide you use will leave a residue to eradicate any ants that come into the nest after you have finished spraying.

Keep a look out for carpenter ants for the next few days. If you see more foraging around the house, it means you have more than one nest around your home. Repeat the procedures to find and destroy any other nests. For more information, contact companies like All Seasons Pest Control.
