What Does Carpenter Ant Damage In Lewisville Homes Look Like?

There are 18 recorded species of carpenter ants in Texas and most of them do not cause much damage to our homes. When they get in, they create nests in walls, ceiling, and floor voids—not within wood timbers. But, there is one species of carpenter ant in Texas that can be particularly troublesome. It is the black carpenter ant, known scientifically as Camponotus pennsylvanicus. If ants of this species find ideal conditions on your property, they can do a lot of damage to your home, over time. Granted, this damage isn't nearly as bad a subterranean termite damage, but it has unique properties that can make your home susceptible to water damage, sun rot, and other weather-related issues. Let's look at what this damage looks like and how it can be a problem for your Lewisville home.


Are you seeing wood that is splitting? It is sometimes difficult to tell the difference between wood rot and carpenter ant damage. If you have wood that is splitting or caving in on a deck plank, you might have a carpenter ant infestation. This kind of damage can increase the damage the sun and the rain can do to these timbers, so it is important to have your infestation addressed quickly.

Tiny Holes

Are you seeing tiny holes in your deck, fence, porch or wood siding? When tiny holes appear in wood, they might be kickout holes created by carpenter ants. Ants don't eat wood. They chew galleries in it. When they do, lots of sawdust (called frass) is produced. This frass is pushed out of kickout holes. Look for this fine sawdust on the ground, floor, or stuck to the wall. You won't have too much trouble with secondary issues from tiny kickout holes, but when carpenter ants create larger holes, rainwater can get in.

Larger Holes

Unlike subterranean termites, carpenter ants don't have a problem exposing themselves to the air. So it is possible to see a hole created by carpenter ants. It is often difficult to tell the difference between a carpenter ant hole and a hole created by rodents or some other pest. If you find a hole that is in a damp location or is in the corner of a window or door frame, you may have a carpenter ant problem. Holes created by carpenter ants shouldn't be very large. They don't have any reason to create large holes to expose their tunneling. Most of the time, these holes will be small (chewed) gaps near the floor that give the ants a large opening to go in and out of a wall nest. Since these holes are usually created in damp locations, this can lead to mold, fungi, algae, and other problems within your home. It can also let rainwater in, which can cause wood rot.
