Identify Pest: Big Ants, Carpenter Ant Infestations, and Carpenter Ant Problems

If you find a big ant in or around your property, you may have a big problem.

Carpenter Ants are a common New York pest problem. A Carpenter Ant infestation can be every bit as destructive as termites. That is why it is important to identify pests like these and get rid of Carpenter Ants as soon as you know you have a problem. If you see even one big ant, call for help.

Carpenter Ants Are Wood Destroying Insects

Ant Pest Control Service Long Island | NYC | Rockland County | Westchester CountyCarpenter Ants, like termites, destroy wood. The damage they cause can be expensive, (like ruining furniture) to devastating, (like weakening the wooden beams that support the floors, walls, and roofs of your home or business). Unlike termites, Carpenter Ants don’t eat wood; instead, they use their sharp mandibles to rip wood apart to build nests, called Galleries. These hollowed out Galleries can severely weaken weight bearing wood beams. Carpenter Ant colonies can contain as many as 40,000 individuals with satellite colonies of 4,000 Ants each. In these numbers, the damage to your property can happen fast and cost thousands.

Signs of a Carpenter Ant Problem

Detecting a carpenter ant infestation isn’t always easy. You can sometime see small holes in wood and piles of sawdust like pencil shavings, but these are not always easy to find. If you have large numbers of large ants in your home, you might have a problem. Some people report being able to hear the ants inside their walls. Carpenter ants will sometimes swarm (often in late winter or early spring) when a colony has outgrown its original nest. A swarm caught inside your home is not a pleasant thing to experience! Getting a professional inspection is the only sure way to stay ahead of these demolition experts.

Identifying Carpenter Ants

Not all Carpenter Ants are alike. This species of pest has a population broken into castes. At the top is the queen, who may or may not have wings. Reproducing males also have wings and smaller heads than the queens. The vast majority of ants in any colony are the worker castes of sterile females. Carpenter Ant workers are either major workers or minor workers. The major workers are larger, sometimes reaching 3⁄4 of an inch long, who guard the nest and forage for food. The minor workers are noticeably smaller, about ¼ inch long. Their role is expanding the nest and caring for the young. The Ants can be found in different color morphologies from deep black that can appear almost purple to rusty red—sometimes one individual will display several colors.

Carpenter Prevention and Treatment

Keeping Carpenter Ants out of your home or business is important. Don’t store firewood near your structure. Inspect it before you bring it inside and burn it right away. Keep tree limbs from hanging over your structure or touching its walls, eliminating a potential highway for ant scouts searching for a new nesting site. Watch out for high moisture situations (after large storms). Ants love moist semi-rotten wood.

If you find a colony or suspect you have a carpenter and problem, get professional help. If you try to treat Carpenter Ant infestation yourself, you might just move the problem from one place in the structure to another. We use special treatments that specifically target Carpenter Ants and have the equipment to deliver these treatments directly into voids in the wood where the ants are living.
