Ants are social insects that live in colonies. Ants are omnivorous with some species feeding on sugary foods. While others prefer fatty or high-protein foods. Ants can be aggressive and are capable of stinging and biting. The red imported fire ant is of specific concern in Nevada because it’s sting can cause severe allergic reactions and even death in some people. Few ant species in Nevada form nests indoors, however, there are a couple of exceptions. Most ants dwell outdoors and enter homes and other structures to forage for food. Sanitation is very important since ants are attracted to attractive foods and grease. Ants are a year-round problem and should be routinely protected against.
