Insect Light Traps attract flying insects by using Ultra-Violet light. Flying insects are drawn by the U.V. light and are either trapped on adhesive glue panels or electrocuted on an electrified grid. Light Traps work 24 hours a day, seven days a week. They catch a variety of flying insects including house flies, bottle flies, yellow jackets, moths and beetles that contaminate food, affect our health, and are irritating. Insect Light Traps are the best continuous tool for flying insect control, working 24 hours a day, 365 days a year.
