Carpenter Ant

December 8, 2014

Family Structure

  • Mature in about two months
  • Immediately start enlarging the nest
  • First year broods are small, with only 10 to 20 workers
  • Quickly matures to thousands in the colony


  • Approximately 1/4″ to 1/2″ long
  • May occur in several colors, although the most important species are black


  • A member of one of the largest ant species
  • Name comes from the fact that they “chew” passageways in wood
  • As they chew, they place the debris outside the nest in piles that look like sawdust
  • These piles, called “frass,” may be first visible sign of carpenter ants
  • Left unchecked for a period of time, these passageways can become quite large
  • Like homes built in heavily wooded areas or low, shady places where the ground stays damp
  • In your home:
    • Around a sink in the kitchen or bathroom
    • Around plumbing leaks, clogged gutters and downspouts
    • In any dark void – hollow curtain rods, hollow-core doors, ceilings, dead wall space, etc.


  • Scavenge your house for food crumbs and insects
  • First thing they do is look for food
  • Carpenter ants do not eat wood
  • Eat thick sugars like jelly or honey, fruits, meats, grease, fat, and other domestic foods
  • Will also eat insects (dead or alive) or any other type of organic matter
