Light traps are designed to attract various flying insects, with moths and flies being among the most commonly captured. These pests are naturally drawn to light due to their behavior and physiology. Many nocturnal insects, including moths, rely on natural light sources, such as the moon, to navigate during their nighttime activities. When artificial light sources are used in traps, these insects often become lured in, making them easy targets for capture. Flies, particularly those in the families of houseflies and fruit flies, are also strongly attracted to light. These pests are often found in environments where light is present, as they frequently frequent areas with food or organic matter, which can coincide with locations where light traps are set. The attraction of light traps to moths and flies showcases the effectiveness of this pest control method in monitoring or reducing populations of these insects. While other pests like ants, termites, cockroaches, and fleas may be involved in different types of pest management strategies, they do not share the same affinity for light and are not commonly captured by light traps.
