How to effectively get rid of carpenter ants

Share via

Bugs! The mere mention of them can make some shudder. But when it comes to carpenter ants, the fear is not just about their creepy-crawly appearance; it's also about the damage they can cause to your home. These large black or red ants may look harmless, but they can wreak havoc on your property by burrowing through wood and causing structural damage.

To effectively get rid of carpenter ants while ensuring the safety of children and pets, there are several strategies you can adopt. These methods focus on both the eradication of existing ants and the prevention of future infestations, utilizing natural, safe remedies and careful application of pesticides where necessary.

Identifying carpenter ants

Firstly, identifying carpenter ant activity is crucial. Look for signs such as piles of sawdust and small, winged ants, which indicate the presence of carpenter ants. These insects tend to form parent colonies outdoors in moist, decaying wood, with satellite nests inside your property in similar conditions​.

Natural and safe remedies

If you have a small infestation, you may be able to eliminate carpenter ants without using chemicals.

For a chemical-safe approach, consider the following:

  • Diatomaceous earth: This natural, non-toxic powder can be applied directly to nests to eliminate ants without posing a risk to your family or pets​.

  • Soap and water solution: Mixing water with dish soap in a spray bottle and applying it to affected areas can kill carpenter ants by breaking down their exoskeletons. Adding a few drops of essential oil, like citrus, can enhance its effectiveness​.

  • Borax and honey trap: This involves placing a mixture of borax and honey where ants are active, which they will then carry back to the nest, effectively killing other members of the colony​​.

  • Bottle trap: A homemade trap using a water bottle filled with a mixture of water, baking soda, borax, and powdered sugar can attract and trap ants, providing a safe and effective solution​​.

Professional pest control methods

While the above methods can be effective for small infestations or as preventive measures, larger infestations, especially those involving the parent colony, might require professional intervention. Pest control experts often use a combination of baits and time-release pesticides containing fipronil, focusing on eradicating both the satellite and parent colonies to prevent re-infestation​​.

The professional process involves:

  • Assessment: A thorough inspection of the property to identify key areas of activity and potential entry points.

  • Treatment plan: Based on the assessment, a customized treatment plan is devised for effective eradication.

  • Application: Pest control experts will use specialized equipment and techniques to apply pesticides in targeted areas, minimizing risks to people and pets.

  • Follow-up: Follow-up inspections and treatments may be necessary to ensure complete eradication.

Preventive measures

Destroy their habits

Carpenter ants are attracted to moist, decaying, or hollow wood. They excavate the wood not for food but to create passageways for their nests. Unlike termites, carpenter ants don't consume the wood, but their nesting activities can weaken structures over time. Signs of an infestation include sawdust-like material (frass) near wooden structures, the sound of rustling within walls, and sightings of large, winged ants, especially in spring.

To prevent future infestations, consider the following:

  • Sealing cracks and crevices: Use caulk or foam sealant to seal any openings or gaps where ants can enter your property.

  • Minimizing moisture: Regularly check for leaks and moisture buildup in and around your property, as this can attract carpenter ants.

  • Proper outdoor storage: Keep firewood, lumber, and other wood materials off the ground and away from your home to discourage nesting.

  • Regular inspection: Regularly inspect areas where carpenter ants are most likely to enter or nest, such as attics, crawl spaces, and decks.

Carpenter ant FAQs

Q: Are carpenter ants harmful to humans?

A: While they do not bite or sting, their nesting activities can cause structural damage and pose a threat to the safety of your property.

Q: How long does it take to get rid of a carpenter ant infestation?

A: The length of time needed to eliminate an infestation can vary depending on the size and severity of the infestation, as well as the methods used for treatment.

Q: Will repairing water damage deter carpenter ants from nesting?

A: Yes, repairing water damage can reduce the attractiveness of your property to carpenter ants, as they are drawn to moist environments for nesting. Ensuring your property is dry and well-maintained can be a deterrent.

Q: Should I remove trees and shrubs close to my home to prevent carpenter ant infestation?

A: While it's not necessary to remove all vegetation, it's smart to trim back trees and shrubs that directly touch your home's structure. This prevents easy access for carpenter ants and other pests from entering your home.

Q: How often should I inspect my property for signs of carpenter ants?

A: It's recommended to inspect your property at least once a year, preferably during spring or early summer when carpenter ants are most active. However, if you live in an area prone to high moisture or have had previous infestations, more frequent inspections may be necessary.

Q: Is it necessary to remove all carpenter ants found in my property, or can some be left alone?

A: It's advisable to remove all carpenter ants because even a few left behind can start a new colony. Left unaddressed, they can cause significant structural damage over time.

Carpenter ants can be a nuisance and a threat to the safety of your home. However, with proper identification and effective treatment methods, you can get rid of them. Effectively dealing with carpenter ants requires a combination of understanding their habits, choosing the right elimination method, and implementing preventive measures. Whether you opt for pesticides or natural remedies, consistency, and attentiveness to potential entry points and conditions favorable to ants are key to keeping your home carpenter ant-free.
