Although there are thousands of different ant species, there are relatively few that we usually see as pests. The most common are listed below. If you are looking for information on carpenter ant control, see our separate page on carpenter ants.


Only 1/8 inch long, the tiny black pavement ant is very common. Large numbers of pavement ants are often found in sidewalk joints and under stones and concrete slabs. Pavement ants do not cause structural damage or present risks to humans, but they are an annoyance inside the home.


About 1/4 inch long, citronella ants swarm in the late winter and early spring. Because of their swarming, they are often mistaken for termites. Unlike termites, citronella ants are simply a nuisance and do not cause structural damage. Citronella ants are so named for the pleasant citronella odor they give off when crushed.


Worker ants are 1/16 inch long and the queen is 1/8 – 1/4 inch long. Both workers and the queen are a yellow-brown color. Pharaoh ants come from the tropics and require artificial heat in order to survive and reproduce. They tend to live in large heated structures like apartment buildings and hotels. The pharaoh ant is one of the most difficult ants to control.


The flying ants we commonly see between July and August are, in fact, sexually active male and female black garden ants. They wait all summer for the perfect conditions to perform their nuptial flight. Once some ants begin to fly, other ants detect their chemical smell and join them. These swarms last all day. Black garden ants can bite if you come into contact with them, which can sometimes cause allergic reactions.

Signs of an Ant Infestation

  • If you see an occasional ant, it may be a scout looking for food and may not indicate the presence of a nest. Continuous or numerous ants, however, is a sure sign of an infestation.
  • If you have exposed food in your home, none of it is safe from ants. This includes leftovers on the counter, pantry food in loosely sealed containers, or even food in your pet’s food dish. If any of your exposed food is overrun with ants, it’s likely you have an infestation.
  • If you see ant mounds close to your home, especially along exterior walls, it may signal an ant problem. Keep in mind that even if the mounds are small, there are hundreds or even thousands of ants below the surface.

Ant Facts

It has been estimated that the total number of individual ants alive in the world at any one time is between one and ten quadrillion (short scale). According to this estimate, the total biomass of all the ants in the world is approximately equal to the total biomass of the entire human race.
