Protecting Your Home from Carpenter Ants: Prevention and Treatment in Mill Creek

Keep Your Home Safe from Carpenter Ants

Carpenter ants may not get the same headlines as termites, but if you’re a homeowner in Mill Creek, they deserve your full attention. These large, black or reddish ants do more than just crawl around your kitchen looking for crumbs. They can chew through wood to build their nests, weakening your home’s structure in the process.

As the leading pest control service provider in the Mill Creek, we’ve seen firsthand how quickly a few carpenter ants can turn into a costly repair bill. Whether you're noticing signs of activity or just want to stay ahead of a potential problem, here’s what you need to know about preventing and treating carpenter ants.

Why Carpenter Ants Are a Serious Problem For Mill Creek Homes

Unlike termites, carpenter ants don’t eat wood. Instead, they tunnel through it to build nests and satellite colonies. Over time, this activity can cause serious structural damage to walls, beams, and other wooden elements of your home.

The real danger is that they often go unnoticed for months or even years. By the time you see a few ants in your kitchen, they may have already built a hidden nest inside your walls or attic.

How to Spot the Signs of a Carpenter Ant Infestation

Carpenter ants are most active at night, which makes them hard to catch in the act. But there are warning signs to look out for.

One of the clearest signs is frass. This looks like sawdust and is left behind as the ants tunnel through wood. You might also hear faint rustling inside walls, especially in the evening. If you notice large black ants (usually around half an inch long) indoors during spring or summer, it’s time to investigate further.

Seeing winged ants near windows or doors is another red flag. These are reproductive ants, and their appearance often means the colony is mature and expanding.

The Role of Moisture in Attracting Carpenter Ants

Mill Creek’s damp climate plays a big part in carpenter ant infestations. These ants are especially drawn to soft, moist wood, which makes water-damaged areas around your home prime targets.



If you have leaks in your roof, around windows, or near plumbing, that moisture can create a welcoming environment for nesting ants. Make it a habit to check crawl spaces, decks, and window frames regularly. Fixing even small leaks quickly can go a long way in keeping your home off their radar.

How to Keep Carpenter Ants Out of Your Home

Prevention is always easier than treatment. Start by trimming trees and shrubs so that branches don’t touch your roof or siding. Carpenter ants often use these natural bridges to get inside.

Inspect the outside of your home for cracks, gaps, or holes, especially around windows, doors, and foundation walls. Sealing these up with caulk can help block entry points.

Also, be mindful of where you store firewood and building materials. It's best to keep them elevated and away from your home to prevent ants from nesting nearby and eventually making their way indoors. For more expert advice and early intervention, our Mill Creek pest control team is here to help you eliminate these pests before they become a bigger problem.

Cleaning and Yard Maintenance Go a Long Way

Like many pests, carpenter ants are always on the hunt for food. Keeping your home clean and your yard well-maintained helps remove some of the attractants that draw them in.

Vacuum regularly, wipe down surfaces after meals, and store food in sealed containers. Outdoors, remove piles of leaves, dead wood, or debris where ants can hide and build colonies. Keep mulch a few inches away from the foundation to avoid giving ants a soft entryway into your home.

Why DIY Ant Treatments Often Fall Short

It’s tempting to grab ant spray from the hardware store when you spot a few scouts in the kitchen. The problem is, these sprays only kill the ants you can see. They don’t reach the nest, which means the infestation continues out of sight.

Worse, disturbing the colony without fully eliminating it can cause the ants to split and form additional satellite colonies in other parts of your home. That’s why most DIY methods offer only temporary relief and sometimes make things worse.
