What does a carpenter ant look like?

Carpenter Ants are one of the largest ants. They are usually 1/4 to 3/8 inch long. Most often they are black in color, however, they can be reddish or yellowish in color, as well. They have a pinched waist and elbowed (or bent) antennas. They have a single bump or node between the abdomen and thorax. Also, if viewed from the side, their thorax is evenly round.

How did the carpenter ant invade my home/business?

Carpenter ants are a common sight around Southern Wisconsin and Illinois businesses and homes throughout the year. Although their natural nesting sites are in trees, carpenter ants can also invade and live indoors. Carpenter ants are active indoors during many months of the year, usually during the spring and summer. When ants are active in the house during late winter/early spring (February/March), the infestation (nest) is probably within the household. When carpenter ants are first seen in the spring and summer (May/June), then the nest is likely outdoors and the ants are simply coming in for food. Nests are commonly found in porch pillars and roofs, window sills, and wood in contact with soil.

How can I tell if I have carpenter ants?

In the spring, carpenter ants send out large swarms of winged adults for reproduction. If there is a nest already inside your home or business, swarms of winged insects often are seen trying to escape through a window. This is usually the first clue that there is a problem. Other telltale signs are piles of wood particles or shavings and large black ants in and around the house. Also, if it's quiet, you might hear these carpenter ants inside the walls.

Can carpenter ants harm my family or employees?

These pests are not a harm, but can be a nuisance.

Can carpenter ants cause damage to my property?

Carpenter ants rarely cause structural damage to buildings, although they can cause significant damage over a period of years because nests are so long lived.

How does Batzner get rid of carpenter ants?

Batzner Pest Management service professionals are highly trained to find evidence of the ants' existence and then to locate and destroy the nest or nests. Carpenter ant control can be difficult. Carpenter ants make their homes in a variety of sites. The nests can sometimes be located by the presence of small piles of sawdust, or frass. This frass consists of wood shavings or other material excavated from the ant's nests, as well as tiny fragments of dead ants and other insects. The presence of frass is a good sign that a nest is nearby. Carpenter ant frass is usually pushed out of a small hole in the nest chamber. Most infestations are difficult to find, since the point of entry may be quite a distance from the location of the nest.

A Batzner Pest Management Service Professional will perform a treatment directly to the carpenter ant nest to eliminate and destroy the nest.

What steps can I take to control or prevent carpenter ants myself?

The best way to keep carpenter ants out is to make your home unappealing to them -- keep your property or home free from water-damaged or damp wood.
