Getting Rid of Carpenter Ants in the House

Once you have discovered and assessed the damage caused by the carpenter ants, it is time for you to take necessary steps to get rid of them. Below are a few steps to combat the carpenter ant infestations:

1. Finding the Nest

The first step to treating the carpenter ant problems is to find the old and new satellite colonies first and eliminate them.

  • Check the infestation where the wood is likely to be damp and cold

As we have mentioned above that carpenter ants reside in damp and decaying wood; it is time to locate their nest in your house. Carpenter ant nests inside the house in damp places such as badly sealed windows, behind bathroom tiles surrounding the bathtubs and sinks, inside hollow doors, under subfloor insulation, in attic beams, wooden porch supports, and columns. You should do routine checks around your house for old and moist wooden spots because carpenter ants might make it their home.

  • Check for infestations by listening for ants in your walls

Sound detection is helpful in finding a carpenter ants infestation. Be vigilant of dry rustling noises, often made by an active colony of ants. Tap on the suspected wood lightly and press your ear to it. The slightest vibration will startle the carpenter ants. You will hear a rustling sound made by ants as they begin to perform random actions.

  • Spotting the worker ants help you locate the ant nest

The most efficient way to spot the carpenter ants is to keep an eye out for worker ants in your house. Worker ants can be seen foraging for food. Use a flashlight covered with a piece of red film and follow their trails. If you find one nest, make sure to search for addition satellite colonies nearby.

  • Remember that ants will travel far while foraging

The carpenter ants might be coming from the outside. Keep in mind that carpenter ants travel far in the search for food. If you see them foraging for food in your kitchen, they might be coming from your attic, porch, window sills or they might be coming from the tree in your yard.

  • Carpenter ants go looking for food primarily when it’s dark

The type of food carpenter ants is attracted to include sweet food, fats, protein, pet food, and honeydew. The carpenter ants are the most active at night time. In the search for food, they leave their nests fifteen minutes after sundown. Most foraging happens between sunset and midnight. A trick to catch the carpenter ants is to place food around your house to attract the ants. Once the ants come to get the food, you can easily follow their trail.

  • Use the toxic bait method

Baits are slow-acting toxin combined with an attractive food source. If you cannot find the nest, then place these toxic baits only around the suspected areas (such as carpets and doorways). Carpenter ants baits can take some weeks or months to work. Do not spray insecticide on the baits, because that will stop the ants from eating the baits. If the carpenter ant swarms the bait, it is a good sign. It shows that the bait method is working. Make sure to clean the bait after 24 hours, whether the ants have eaten it or not. Leaving the baits for a longer period can be a danger to the health of children.

Ant-dust is more efficient in killing the ants as compared to baits. Make sure that you have made enough hole in the infested area for better

  • Try a boric acid bait

Boric acid is also a product to combat carpenter ants problem. It is an odorless, non-staining powder readily available in stores. Like toxic baits, boric acid is a powder that contains food substance to attract ants. Eating boric acid kills the ants because it works as a stomach poison. While eating, carpenter ants dabs into the powder which sticks to the ant’s legs, it then enters into their crevices and cracks, gradually leading them to their death.
