Don’t Let Carpenter Ants Renovate Your Home!

Carpenter ants are the most common ant pest found in the Northeastern United States. They cause structural damage when they excavate wood for nest sites. Unlike termites, carpenter ants do not eat wood, but rather scavenge on dead insects and collect sugary secretions (“honeydew”) produced by other insects such as aphids. Carpenter ants are a nuisance pest when workers are spotted inside foraging for food and when winged swarmers are found inside.

Did You Know … ?

  • Wood is Not-So-Tasty: Carpenter ants tunnel through moisture-damaged wood and spit out wood shavings. The resulting waste piles look like sawdust and often include ant body parts.
  • A Numbers Game: There are approximately 24 species of carpenter ants that are pests in North America; nine of these species are present in the northeast.
  • Hanging Out: Carpenter ant larvae are clumped together by J-shaped hairs, and cling like Velcro to the roof of their galleries.
