How to Identify Carpenter Ants

The 2 most common types of carpenter ants are the black carpenter ants and the red carpenter ants. Carpenter ants are larger than most, with their size ranging from 6 to 25 mm lengthwise. Their bodies are divided into 3 sections, with a slim waist separating the upper and lower body. Carpenter ant’s antennae are also sectioned and bent. When a colony is mature, a generation of swarmers is produced. Swarmers are both male and female and their purpose is to reproduce and form new colonies. 

Signs you Have Carpenter Ants in Your Home

The most common signs that you have a carpenter ant problem in your home are: 


  • Damaged wood  
  • Sawdust piles
  • Discarded wings: near windows.  
  • Forager ants
  • Audible sounds: rustling in the walls or hollow sounding wood when tapped.

 

You may see more live ants in the evenings as that’s when they are most active.   

Best Ways to Prevent Carpenter Ants

It’s vital to take preventative measures so that you minimize the risk of  infestations. The following are preventative measures you can take: 

 

  • Eliminate moisture: Carpenter ants are attracted to damp wood since it’s easier for them to chew through, so it’s best to repair any leaks or moisture problems within your home. 
  • Trim vegetation: Keep tree branches, shrubs, and vegetation away from your house to prevent ant highways. 
  • Seal entry points: Seal cracks and gaps in the foundation, walls, and windows to prevent ants from coming into your home. 

Remember to also store firewood away from your home and inspect it before bringing it indoors. Make it a point to regularly inspect wooden structures for signs of damage so that any issues can be resolved immediately.   

How to Get Rid of Carpenter Ants?

Locating and treating the main nest is the first step in effectively eliminating carpenter ants. Some of the most common ways to get rid of carpenter ants on your own is to use bait specifically made for carpenter ants, and mix it with a sweet substance. The worker ants will bring it back to the colony, where the other ants will eat it and die. 

If you suspect an infestation it’s best to call your local pest control professionals so you get the most accurate identification, precise treatment, and long-term elimination.
