How to Keep Carpenter Ants Out of Your Home

Abell Pest Control How to get rid of carpenter ants in your home

Carpenter ants are more than just a nuisance—they can cause serious damage to your home’s wooden structures. Contrary to popular belief, these ants don’t eat wood; they chew through it to build nests and tunnels, making their colonies harder to detect until significant damage is done. Here’s how to spot, prevent, and manage carpenter ant infestations.

Where Carpenter Ants Are Found

Carpenter ants typically nest in damp, decaying wood, making wooded areas the perfect environment for them. Their colonies often start in rotting stumps or fallen trees, forming a “parent colony.” From there, worker ants may venture out to create satellite colonies, sometimes moving into homes and outdoor wooden structures like decks or sheds.

Spring is prime time for carpenter ants, as the combination of warming temperatures and rainy weather creates the damp wood conditions they love. If you spot ants indoors during late winter or early spring, they may have already established a colony inside your home.

Common Hiding Spots in the Home

Once indoors, carpenter ants are usually found in areas where moisture accumulates. These include:

  • Under Sinks or Around Tubs: Water leaks can soften the wood around pipes and create an ideal nesting site.
  • Window Frames: Poorly sealed or cracked windows allow moisture to seep into the surrounding wood.
  • Basements and Crawl Spaces: Dark, damp environments are perfect for carpenter ants to settle and expand their colonies.

Tips to Keep Carpenter Ants Out

  1. Inspect Your Home Regularly Do routine checks around your home, especially in moisture-prone areas like sinks, bathtubs, and windowsills. Look for leaks, wood damage, and signs of ants such as sawdust-like material (called frass) or discarded wings. Repair leaks immediately and replace any water-damaged wood.
  2. Remove Rotting Wood Outside Look around your yard for rotting tree stumps, logs, or old wooden structures. Even if they appear ant-free, they could become a nesting site in the future. Dispose of them properly to prevent potential infestations.
  3. Trim Back Trees and Bushes Tree branches that touch or hang close to your home can act as highways for carpenter ants. Trim them back regularly to minimize access to your roof, siding, or windows.
  4. Seal Gaps and Cracks Use caulk or weatherproof sealant to close off cracks and crevices in your home’s foundation, walls, and window frames. This can block potential entry points for carpenter ants and other pests.

By staying proactive and addressing moisture issues early, you can protect your home from carpenter ants. Regular inspections, repairs, and yard maintenance go a long way in keeping these destructive pests out of your living space.
