Electric fly killers, sometimes called "fly lights", are a very effective way to catch and kill flies. Blue or green UV lamps attract the insects, which then encounter a live grid that electrocutes them. Fly lights are non-toxic and can be used in every location. MS Schippers offers a full range of electric flytraps for every situation, from a small and simple fly light for domestic use right up to dust and water resistant fly killers for insect control in animal housing.
