Ants are the most common pest problem reported. These tiny scavengers will enter your home or business looking for moisture and an accessible food source. Moisture, sweets, and conducive nesting sites are common attractants. Check out our collection of pictures and information on these very small but difficult critters.

Odorous House Ants

Description: Odorous house ant workers are brown to black and 1/16 to 1/8-inch long. The best identifying characteristic is the rancid butter smell these ants produce when they are crushed, hence their name. When alarmed, the workers scurry around with their abdomens raised in the air.

Carpenter Ants

Description: The carpenter ant, Camponotus pennsylcanicus, is in the east and C. modoc in the west are the most thoroughly studied species in the U.S. They are among the largest ants found in the U.S., ranging from 1/8 to ½ inch long, the queens are slightly bigger. The workers of an established colony vary in size.

Pavement Ants

Description: Pavement ants are 1/16- 1/8 inch long with a dark body and lighter colored legs. They are easily identified by the narrow, parallel grooves on their heads and thoraxes.

Pharaoh Ants

Description: Pharaoh Ants are very small: workers are about 1/16 inch long. They range from yellow to light brown. They can be distinguished from the thief ant because they have a three-segmented club at the end of the antenna.

Argentine Ants

Description: The Argentine Ant is a relatively small ant (the workers are about 2.5 mm in length and the queen is about double that size), light brown to dark brown in color and have one node on their pedicel.

Acrobat Ants

Description: Acrobat ants get their name from their habit of raising their abdomen above their head, especially when they are disturbed. When they are viewed from above, the abdomen is heart-shaped. Most species are less than 1/8″ in length. Many give off a disgusting odor when disturbed.

Thief Ants

Description: Thief Ants are very tiny ants, workers are never more than 1/16- inch long. Thief ants are yellow to light brown and look much like Pharaoh ants.
