A glue trap is a type of pest control device designed to capture small animals, such as rodents and insects. It consists of a flat surface coated with a strong adhesive that immobilizes the target when they walk across it. Glue traps are often used in homes and businesses to monitor and control pest populations without the use of poisons. These traps are typically placed in areas where pests are frequently seen, such as along walls or near food sources. While they can be effective, some people criticize glue traps for being inhumane, as captured animals may suffer before dying.
