Developed to be the most effective glueboard flylight on the market, EdgeTM is designed around patented* glueboard technology to catch significantly more flying insects than traditional glueboards. As the glueboard is inserted into the flylight it self-folds at the desired points, creating a unique form around high efficacy SynergeticÂ® UV bulbs. This unique design forms edges, proven to be more attractive to flies, maximizes useful UV light output, and creates a 30% larger glue area than traditional glueboards, creating a staggering 31.5% increase on a normal catch rate!
