Using spearmint gum, red pepper, orange peels, cinnamon, or other herbsĭrenching a nest many times with an insecticidal soap solution is sometimes effective in forcing an ant colony to relocate.Pouring gasoline in a nest (it is dangerous and causes environmental pollution).These methods are NOT effective to get rid of ants: Common examples of available insecticides have active ingredients such as: Insecticides used for treating the exterior of a building may be a liquid or granules. This control method is temporary and is not a long term solution. If it is not clear where the ants are entering, then treat a 2- to 4-foot wide area around the entire building. If ants are entering only through one area of the house, you can spot-treat that area. If the nest cannot be found, in some cases ants can be kept out of the house by applying an insecticide barrier around the exterior of the building.Retreatment of nest sites may be necessary if above-ground activity resumes after the initial application.Common examples of active ingredients include bifenthrin, cypermethrin, gamma cyhalothrin, and lambda cyhalothrin. You may need 1/2 gallon or more of mixed material to treat large nests. Liquid insecticides can work if they are soaked into the nest.Granules and dusts are most effective, these products contain active ingredients such as permethrin or deltamethrin.Be sure to select a product that has directions for treating lawns. Outdoor nests can be very difficult to get rid of without applying an insecticide. Tolerate ant nests in lawns when possible. Diligent observations can pay off as locating and treating the nest directly is often the most effective way of controlling ants.Īnts can also be a nuisance in lawns because of the mounds they produce, especially if they are abundant. In some cases, ants may need to be observed for 30 minutes or longer to locate a nest. When the nest is found, it can be treated. For some ants, such as carpenter ants, this works best at night, just after sunset. The nest may be found by watching where the ants go. You can encourage foraging by setting out attractive food.Īnts usually take regular routes to and from their nest by making a chemical (pheromone) trail. Many ants enter homes from outside nests as they look for food. Because different species may be treated differently, be sure an ant problem is correctly identified before attempting control. It is often challenging to recognize ants from a picture. The colonies of some ant species contain just one queen while others have multiple queens.They have very large abdomens and can live for a number of years.Queens have wings but break them off after mating.Queens are the largest members of the colony, often two to three times larger than workers. Their sole purpose is to mate with the new queens they die shortly afterward.They are found in older, large colonies.They have wings and a small head with large eyes.Males are generally the same size or larger than the workers. The reproductive members of the colony are the males and queens. The workers take care of the work in the nest, including expanding the nest, food gathering, caring for the eggs and larvae, and defense of the nest Some ants vary in size and are divided into major (large) and minor (small) workers. Different castes have different responsibilities in the nest. Typical ant castes, from left to right: queen, winged male, major worker, minor workerĪnts live in colonies and are divided into different castes: workers, males and queens. The presence or absence of simple eyes (ocelli) on the head.Īn ant’s biology can also help identify them, such as where they are nesting and when they swarm (when females and males fly out of their nest).The number of segments in the antennae and whether a club (enlarged segment at the tip) is present.
