How Do Bug Zappers Work on Flies?

Bug zappers work by zapping insects with an ultraviolet light. UV light is attracted to insects because it is shorter wavelength than regular light. Because of this, insects such as fruit flies and mosquitoes are attracted to this light and fly into the zapper. Most bug zappers use shatterproof UV tubes to emit this light.

Bug zappers trap a variety of insects, including aquatic and parasitic insects. Eventually, these insects are eliminated, which can affect the ecosystem as a whole. Many fruit flies and other insects depend on insects to survive, so the zappers can have detrimental effects on them. For example, the zappers may eliminate the beetles that are the food source for songbirds.

Other solutions to fly infestations include insecticide baits. These lures are available in several forms, but all use a safe chemical called tricosene. Glue traps are very effective at attracting and killing flies. Unlike bug zappers, glue traps do not use electricity and are more targeted. While they can be ugly to look at, they are effective in killing flies.

Bug zappers are most effective at zapping flies, but they are also effective against other flying insects. Bug zappers can be used during the day as well. The light inside the house makes the bug zapper more effective than it would be outdoors. However, if you are using the bug zapper outside, you may want to consider a bug zapper with a removable tray to catch dead insects.
