Ants Living In Walls? Here Is Our Guide On How To Deal With Them

1. What ant species live in walls, and what do they eat

There are a variety of ants that you can find living in walls. These include carpenter ants, sugar ants (a common ant species), and Pharaoh ants.

Each type of ant lives in different conditions and feeds on different things.

Carpenter ants live in moist wood and can even eat the wood itself. Sugar ants live in sweet food and drink spills.

Pharaoh ants live in warm, dry environments and eat anything from meat to sweets.

It is fair to say that most ants will eat sweet stuff if they are available, so it is essential to keep your kitchen and other areas of your home clean and free of food spills.

Ants in your walls could indicate that a food source is easy to access near the infestation.

Find it, and remove it.

2. Signs of an ant infestation in your walls

  1. Ants marching in single file lines from inside your wall (visible ant trails)
  2. Small mounds of soil near the wall.
  3. Piles near your wall that look a little like sawdust.
  4. Flying winged ants inside your home.
  5. A few ants are coming from the external-facing side of the wall.

4. How to get rid of ants in the wall permanently

  1. Ant traps. Ant traps with pesticides are the easiest way to get rid of ants in wall spaces. The ants will pick up the bait and take it back to their nest, killing multiple ants with just one trap.
  2. Remove the food source. Ants are attracted to food, so remove all food sources from the vicinity of the ants in the wall. This is vital – if they can’t access food, there is no point in them being there!
  3. Use a homemade solution. Mix a detergent solution (1 tablespoon of dishwashing liquid to 1 quart of water) and spray it on the ants in the wall if you can get to them. If not, spray all ants that you can see. Other ingredients that are good to get rid of ants are vinegar and lemon.
  4. Use a pesticide spray. Spray a pesticide (such as Raid) on the ants in the wall. If it is a significant infestation, you might want to consider drilling a hole big enough to spray pesticides into the wall to get better access to the nest.
  5. Seal off entry points. Use caulk or expanding foam to seal off any entry points that ants may be using to get into your wall. Ants are tiny, and it is easy for them to find a way in and out, but by limiting this, you reduce the chances of them getting in and out of your walls.

5. DIY methods for getting rid of ants in your home

I said it a few times, but the best way to get rid of ants in your home is to find the nest and destroy it.

Usually, I would pour boiling water over the nest, but I don’t recommend that for an ant nest in your wall!

You can use the following items to get rid of ants:

  1. Vinegar
  2. Lemons
  3. Borax (and honey)
  4. Diatomaceous Earth
  5. Spray with soap – as I mentioned above, use a spray with water and soap and apply generously.

7. Prevention tips to keep ants out of your home

There are many ways to keep ants out of your home. For example, some people use chemical deterrents, while others use natural methods.

There are also several everyday household items you can use to keep ants away.

Here are some tips to keep ants out of your home:

  1. Close entry points: This is vital. Close off the entry points, and they can’t get into your home.
  2. Remove things they are attracted to: This includes food and water. Remove easy access to pet food. Try not to leave pet food in bowls for long periods, especially if you will not be at home.
  3. Use chemical deterrents: Many products on the market can be used to deter ants from entering your home. Products like Terro work by luring the ants to a bait station, where they will then die.
  4. Use natural methods: If you don’t want to use chemicals, you can use natural methods to keep ants out of your home. One way is to sprinkle cinnamon or black pepper around the entrances to your home. You can also put Vaseline around the edges of your doors and windows.
  5. Clean regularly: Ants leave trails for other ants to follow, usually food.
