How to Get Rid of Carpenter Ants Outside

There are a variety of strategies you can deploy to solve a carpenter ant infestation. Here are our top five methods for getting rid of carpenter ants:

Use Toxic Bait to Get Rid of Carpenter Ants Quickly

If the carpenter ant colony is concealed or inaccessible, this strategy is highly recommended. Head to your local hardware store, buy poisonous gel bait for carpenter ants, and combine it with a teaspoon of sugar and a teaspoon of milk.

Apply the poisonous bait to entice the carpenter ants out of their nest; they will grab the bait and take it back into the nest. If applied correctly, this method will get rid of an entire carpenter ant population in three days. This is one of the most effective ways to achieve total carpenter ant control.

It is critical to treat carpenter ants with slow-acting bait. If the bait kills carpenter ants as they are returning to the colony, the thousands of ants still inside the nest won't be affected. Select a bait that takes roughly three days to work.

Never spray insecticide on carpenter ants emerging from the nest. This will not affect the ants that are still inside the colony and may even cause them to spread out and build more nests if they detect danger.

Tamper-proof bait stations offer a safe alternative for administering poisonous baits if you have pets or young children.

Treat Nests with Direct Dusting

This technique works best when you have easy access to the nest and can directly administer carpenter ant dust to the queen and the entire ant colony. Purchase carpenter ant dust, then apply it to the nest as directed on the packaging.

To get rid of carpenter ants quickly, try D-Fense Insecticide Dust. It is an effective and fast-acting chemical dust, but it does contain toxic chemicals that could be harmful to children’s and pets’ health. Ensure you apply it safely and correctly with a duster.

Try Boric Acid

Boric acid is a powerful chemical that can quickly get rid of a carpenter ant infestation. To use this technique, visit a garden supply store to get boric acid.

Mix powdered sugar in a ratio of roughly 1/3 sugar to 2/3 boric acid. Pour the mixture into bottle caps and place them wherever you see the carpenter ants.

The ants in the nest will be killed when worker ants bring the acid back to the nest. Boric acid penetrates the ant's body, which then dissolves inside the ant.

Get Rid of Carpenter Ant Scent Trails

Pheromone trails are essential for the movement and discovery of food sources by carpenter ants. You can successfully eradicate this “treasure map” leading them to your home by cleaning surfaces ants have walked on.

Disrupt these scent trails by wiping surfaces with a cotton ball dipped in essential oils such as tea tree, cedarwood, or citrus.

Alternatively, prepare a solution consisting of one part liquid dish soap and two parts water, then transfer the mixture to a spray bottle. You can also use a solution that consists of equal parts water and white vinegar. Spray the mixture over the trails or inside the nest if you have located it.

Apply Diatomaceous Earth

Diatomaceous earth is a natural substance that gets rid of carpenter ants and other insects by dehydrating them. Diatomaceous earth is an efficient insecticide for getting rid of carpenter ants because it breaks down the ants' tough exoskeleton.Unlike other desiccant products, diatomaceous earth is available for purchase and application in the comfort of your own home because it is a completely organic pesticide.

Be very careful when handling this product because breathing in the dust could damage your lungs. While it is safe for pets and children, you should still exercise caution.

Apply diatomaceous earth in the same manner as boric acid dust: drill holes measuring one inch in diameter every six inches and then blow the dust into the holes.

When applied correctly, diatomaceous earth has the potential to get rid of carpenter ant nests naturally and quickly.

Identifying Carpenter Ants

What are Carpenter Ants?

Carpenter ants are naturally found in several areas around the world. They construct their distinctive, smooth nests outside in wet, decaying wood. They do this by removing pieces of wood to make galleries—pathways through the grain of the wood that lead to various nesting locations.

Nesting sites for carpenter ants can be found anywhere inside that has a natural cavity or hollow, including doors, window sills, tree branches, and wall voids.

How to Inspect for Carpenter Ants

Step 1 - Make Sure You Have Carpenter Ants, Not Termites

Verify that you are dealing with ants and not termites. Carpenter ants are large insects that can be black or dark brown in color and have three body segments and six legs.

They have antennae that curve inward. Reproductive carpenter ants have wings, but worker ants do not. Termites, which are a much more serious problem, have straight antennae and light-colored bodies.

Step 2 - Look for Frass

Frass resembles sawdust and is produced when ants drill into wood to construct their nests. It will appear to be a mound of light wood shavings, but it may also contain pieces of debris and waste.

If you notice this around your home, it is a clear indication of an infestation, and you need to take action to get rid of carpenter ants.

Step 4 - Place Bait in the Area

To find the nest, lure the ants out with bait, then follow them back to their nest. Place small pieces of honeydew melon or other sugary fruits near the suspected location.

Step 5 - Follow the Ants to the Nest

When you see the ants take the bait, track them back to their colony. You will likely see them entering through a crack in the wall, floor, or doorway.

If the nest is visible and accessible, you can eliminate it directly.

If the nest is difficult to find or access, consider using poisonous bait to eliminate the colony rather than trying to locate and destroy it manually. This process typically takes around three days.

How to Prevent Carpenter Ants from Coming Back

Once you successfully get rid of carpenter ants, the last thing you want is for them to return. Below are four crucial tips to prevent a future infestation:

1. Remove Clutter from Your Home

Get rid of clutter and mess to prevent carpenter ants from using it as a nesting place. Clean thoroughly, repair any leaks that could cause wood to rot, and remove any potential hiding spots.

2. Make Sure Your Home is Sealed

Prevent ants from entering your home by using caulk to plug cracks in the foundation and crevices around entry points. Install screens on doors and windows to keep carpenter ants out.

3. Clean Up Any Natural Debris Around the House

Reduce the height of any tree limbs that hang directly over your home by cutting them back. It is important to get rid of carpenter ants on trees around your home because they could enter on overhanging limbs. You should also remove any weeds, old wood piles, and natural debris, because they may be housing an ant colony.

4. Sweep Up Food Crumbs, Clean Spills, and Fix Any Leaks

Ants require sugar, protein, and water to survive. Keep these essentials away from them by maintaining a clean home.

Ensure no crumbs are left on floors or countertops, and clean up spills immediately, especially those involving sugar. Eliminate any standing water and fix leaking faucets.
