About Ants
The number one nuisance pest in North America, ants make up the majority of local pest problems. Varying by species, the average colony is made up of anywhere between 300,000 to 500,000 ants. With the capability of surviving more than seven years, it’s no surprise that they are likely to take up residence in your home.
Ants are one of the most prevalent insects, with more than 10,000 different species throughout the world. Ants are social animals that live in groups, or colonies, with a colony having as many as a million ants in residence. Three types of ants live in the colony:
- Queen: The queen is the largest ant in the colony. Her role is to reproduce, laying thousands of eggs over the course of her lifetime. Depending on its size, a colony can have one or multiple queens.
- Female ants: Also known as worker ants, females are responsible for finding food, caring for the queen’s offspring, and maintaining and protecting the colony. Other than the queen, female ants do not reproduce.
- Male ants: The singular role of the male, also called a drone, is to mate with the queen.
What do ants look like?
Ants are generally red, dark brown, or black. They range in size from 1/8” to 1/2”, though some species can grow as large as an inch. Their bodies consist of a head, thorax, abdomen, six legs, bent antennae, compound eyes, and strong jaws known as mandibles. The ant’s anatomy resembles a figure-eight, with a constriction between the thorax and abdomen. Queen and male ants have wings, though most common varieties do not usually fly. Ants don’t have ears, and “hear” through vibrations. They also lack lungs and instead process oxygen through holes called spiracles. Ants have two stomachs — one for food they consume and another to hold food to take to the colony.
Ants mature quickly, going from egg to larva to pupa to adult in a matter of weeks. Males typically live less than a month, dying shortly after mating. Worker ants live for up to 3 years and the queen can survive as long as 30 years. Once the queen dies, the colony is unable to survive because it is unable to replace her.
What are the unique characteristics of ants?
Ants are omnivores, feeding on anything from seeds to other animals. They are very organized, often working together in large groups to build their nest and gather and transport food. Depending on the type, an ant can carry 10 - 50 times its own body weight. Ants communicate by emitting chemicals that warn of danger and potential food sources. As they travel, they discharge pheromones to mark their trail, which is why you often see ants marching in a line.
DIY Methods of Ant Control
While the most effective way to prevent or address an ant infestation is to call in pest control professionals, you can also try these do-it-yourself methods:
- Place natural repellents like coffee grounds, peppermint oil, and lemon in areas where ants are likely to enter. This will keep ants at bay, but will likely not resolve the source of an ant problem.
- Clean with a solution of equal parts water and distilled white vinegar, which ants dislike.
- Poison ants with bait stations or topical solutions from a home supply store. Ideally, the worker ants will take the poison back to the queen and eradicate the colony. However, in many cases, the workers die before they ever get back to the nest, so the poison doesn’t make it to the source of the problem.
What can you do to prevent ants from settling in your home?
Ants are driven by a search for food, water, and shelter. While it may be impossible to stop every ant, following some basic guidelines can help prevent an invasion:
- Avoid leaving food, dirty dishes, or food particles where ants can get to them. Though they aren’t very selective, most ants are drawn to sugary, fatty, or greasy foods.
- Use gap sealant or caulk to seal cracks and openings around windows, doors, and pipes so ants can’t enter your home.
- Remove debris, rotting logs, and lumber from your yard.
- Repair leaks and dry out moist areas in your home.
