How To Identify And Eliminate Carpenter Ants


What is a carpenter ant?

Carpenter ants have six legs, two antennae, and three main body parts. They are mostly black, with some reddish areas. You will typically see carpenter ants traveling together in large numbers, on invisible highways, in your grass, on your walkways, and inside your home. They have strong mandibles and use them to excavate their way through wood and wood structures to use it for nesting. Typically these ants are black, red or brown, or varying combinations of red and black. The workers in the colony can range between 1/8 to 1/2 an inch in length and the queen up to 5/8 inches in length.

Why do I have them?

carpenter ant colony will normally be established in decaying wood and only then will they move into more sound wood. It is fairly typical that if you discover a nest inside your home that it is a satellite colony that was started by a larger colony located somewhere outside your home. Ants prefer to be outside and the reason you will find them indoors is that they are foraging for food. Carpenter ants are very determined insects and will find many ways to get into your home - entering through eaves, door frames, window frames, plumbing, and utility lines.

Are they dangerous?

Carpenter ants are not usually known as biting insects, as the primary concern with these pests is always their capacity to cause structural damage to your home.

Carpenter ants are particularly difficult to eradicate because they can have a network of many nests that are all interlinked. If one of the nests is missed in the treatment process then the ants can rebound and reform - that's why our carpenter ant program includes all the necessary inspections and treatments to eradicate your carpenter ant problems.
