Carpenter Ants

Carpenter ants are common in North America and are some of the largest ants on the continent. Most species are black, but some are brown, red and black or completely red. In nature, the carpenter ant is actually very beneficial in that it feeds on other pests. However, these ants love to inhabit wet wood and can infest hollow doors, wood kitchen cabinets and window frames. While they don’t eat the wood, they are known to tunnel into the wood to build their colonies and will eat human food within your home.

FAQs about Carpenter Ants:

Where am I most likely to find carpenter ants?

Carpenter ants prefer moist areas and may construct their nests anywhere in the home including walls, ceilings, attics, doors, sills, shingles and insulation. Carpenter ants are most active during the night when they forage for food.


Are carpenter ants hazardous to humans?

Yes. Since carpenter ants are attracted to foods such as honey, jelly, fruit and meat, they can carry disease germs from one area to another. Although they do not sting, they can inflict bites.


Do weather conditions affect the size of a carpenter ant infestation?

Yes. Warm, moist weather presents ideal conditions for carpenter ant colonies to establish themselves.


How can I tell if I have a carpenter ant infestation on my property?

The presence of worker ants in your home is one of the first indications of an establishing carpenter ant colony. Check all areas where you suspect moisture. The presence of frass (chewed wood similar to sawdust) is an indication of an active nest. Any flying insect in the home is cause for concern and a professional in pest control should be consulted.
