Group of pavement ants on pavement. Pioneer Pest Management serving Portland OR & Vancouver WA talks about how to help prevent a pavement ant infestation.

Pavement ants are a common nuisance pest in the Pacific Northwest, especially in summer and although they’re known to form colonies near pavement, they’ll also invade your home if given the chance. So how do you help prevent that from happening? With helpful tips from Pioneer Pest Management of course!

What are Pavement Ants?

Pavement ants are small, dark brown to black colored ants that have parallel lines running down their backs. They typically feed on honeydew, insects, fats, meats, and starches, but will eat nearly anything, including pet food. While pavement ants have the potential to sting, they rarely do. However, they can contaminate food through the waste they leave behind.

Pavement ants are social pests. They’ll form colonies ranging in size from 3,000 to 4,000 in size, having several queens. Once they gain access to your home, they’ll nest under your flooring, within walls, or even in your insulation.

Signs of a Pavement Ant Infestation

Seeing worker pavement ants in your home is generally the best way to identify if you have an infestation. These pests typically invade homes after sunset while foraging for food. In fact, they’ll leave their colony as far as 30 feet away while searching for food. Other indicators include excavated soil (outside your home) and swarmers (in spring).

How to Help Keep Pavement Ants Away

  • Eliminate sources of standing water like plumbing leaks and pet bowls
  • Trim back shrubs at least 18” away from your home as ants will use them to gain entry inside
  • Caulk cracks in your foundation, and around windows and doors
  • Take out your indoor trash regularly and make sure your outdoor trash cans have properly sealed lids
  • Maintain cleanliness, removing crumbs and spills immediately
  • If you store firewood, keep it away from your home as ants and other pests like to nest in wood
  • Don’t leave any food out, including pet food. Instead, store your food in airtight containers. This will help keep your food fresh and help deter pests
