Up close look at ants and wet substance. Pioneer Pest Management talks about how to help keep odorous house ants out of your Portland OR or Vancouver WA home.

Odorous house ants are a very common pest in the Pacific Northwest. They can be identified by their black or dark-brown bodies and by their odor—a rotten, coconut-smelling stench that emits when they’re crushed.

Although odorous house ants are not particularly dangerous, they can contaminate food and trigger allergies. For these reasons, here are some tips from Pioneer Pest Management to help keep odorous house ants out of your home.

Eliminate Moisture

Like many pests, odorous house ants are attracted to moisture. They will nest near stacks of firewood, near hot water heaters, and beneath leaky plumbing fixtures. Make sure to repair dripping faucets and leaky pipes to eliminate standing water.

Seal Entry Points

Odorous house ants are tiny. To ensure they don’t get into your home, seal any cracks or openings around your foundation, windows, and doors.

Trim Landscaping

Sometimes odorous house ants will use branches or plants to get into homes. Prune branches and plants to keep them away from directly touching your house. It’s also a good idea to store firewood piles on a raised structure at least 20 feet away from your home.

Keep Your Home Clean

Odorous house ants are attracted to sweets, dairy, meat, and even pet food, so don’t leave food out and clean up spills immediately. We recommend storing your food in airtight containers. It will keep unwanted pests out and keep your food fresh.
