Washington DC Carpenter Ant Treatment


Carpenter Ant

How To Identify A Carpenter Ant Infestation

Appearance - Carpenter ants are usually large and black colored, with bent antennae, a narrow waist, and longer front wings. Carpenter ants are often confused for termites which have straight antennae, a thick waist and four wings all the same size.

Behavior - Swarmer carpenter ants have the ability to fly, and often are sent out from an existing parent nest to create a new satellite colony. When they find a location to nest, you may start to see holes in the wood of your Washington DC home, such as in the walls or on your porch. Termites can leave mud in the excavated areas, so it does not look smooth. Unlike termites, carpenter ants do not eat wood and will leave wood bits and dust behind as a sign of their current residence in your walls.

Why You Might Have Carpenter Ants

Carpenter ants seek out damp and rotting wood to live within. They like to live in tree stumps or fallen, rotting logs where moisture is present. Parts of your home that are exposed to the elements are most susceptible to carpenter ant damage.

Reasons To Treat Your Carpenter Ant Problem Immediately

Carpenter ants tend to be a nuisance, and an untreated colony can pose a threat to the stability of your Washington DC residence. Too much burrowing into the wood could compromise the integrity of some housing structures. Satellite colonies may pop up if a nest is left untreated for an extended period.

Getting rid of carpenter ants ensures that your home will stay safe from their burrows. Professional carpenter ant control is the most effective way to kill carpenter ants and stop their colonization in its tracks.

Call us today to treat or prevent your carpenter ant problem so you and your family can rest assured the structural integrity of your Washington DC home will be safe. We are the top Washington DC carpenter ant control company.
