Although carpenter ants do not eat wood as termites do, they have powerful jaws and make tunnels in the wood structure of your home. Carpenter ant swarms portend damage to your home and property.

Moisture Ants

They may take up residence near leaks in plumbing systems, an attic or crawl space, or rotting wood in bathrooms or basements.

Moisture ants may also nest outdoors near windows or doors that provide easy access indoors to scout for food.

Aggressive Types of Ants

Nuisance Types of Ants

Ants don’t have to be destructive to be an ongoing nuisance and concern. There are nearly 1,000 species of ants in the United States. Their skill in building large colonies and finding food inside your home can become exasperating for homeowners.

Argentine Ants

These tiny creatures love to invade homes in search of sweets and water. Argentine ants establish supercolonies that may have over a billion ants.

This is because Argentine ants have multiple queens – as many as 300 queens for every 1,000 workers.

Bigheaded Ants

Bigheaded ants also create super-colonies with multiple queens.

Citronella Ants

Ant Control - Croach - Kirkland, WA - Types of Ants - Citronella AntThese yellowish ants would most likely go unnoticed if it wasn’t for the swarmers (winged ants) who leave the nest to mate and start their own colonies.

While swarming, citronella ants will sometimes enter your home.

Field Ants

Field ants can vary in color, from a yellow to a red and sometimes red and black. They are very common to find outdoors but will go indoors to forage for food.

Field ants do not have stingers but will bite if they feel threatened. Some field ants spray formic acid into the wound, which can be very painful.

Ghost Ants

Ghost ants are tiny with a dark head and thorax and a pale abdomen.

They will sometimes build their nests inside your home inside walls, behind baseboards, or even in the soil of potted plants.

Ghost ants require a lot of water and are most commonly found in kitchens and bathrooms.

Odorous House Ants

Odorous house ants have multiple queens and multiple nesting sites making them hard to get rid of. They often build nests indoors near water and sweets.

Also known as sugar ants, they have a serious sweet tooth and are not shy about strolling your kitchen in search of treats day or night. They have a distinct blue cheese or coconut odor when crushed.

Pavement Ants

Brown to black in color, pavement ants can be found nesting in cracks in pavement such as sidewalks, driveways, or patios.

They love to forage inside for all the delicious food you have to offer.

If open food packaging, trash cans, crumbs or spills, or pet food is regularly available, pavements ants can become a serious problem.

Thief Ants

Thief ants will live anywhere and eat almost anything. They particularly enjoy greasy food like potato chips. They are known to steal food from other colonies, hence the name.

Once they get into your house it is hard to manage them because they are so tiny at only 1/16-inch long. No snacks are safe as thief ants can get into seemingly sealed or contained items.
