One thing to note is that this zapper is loud and very bright so if you are using it indoors, you will want to put it in an area you can avoid. Our top pick is the Starbar Fly Terminator Pro, a powerhouse trap that can catch 35,000 flies, horseflies, deer flies, and gnats before it needs emptying. We tested this product at home and found that the ultraviolet light attracted flies as well as mosquitos, gnats, and beetles.

The like charges contained inside the mylar strips repel each other which causes the mylar itself to expand as a result. In summary, the charge of the wand (positive or negative) becomes the same as the charge of the belt just after it contacts the first roller at the bottommost position of the fly stick. The belt then, being either positively charged or negatively charged, travels to the wand end of the stick where it contacts the second roller (which is made of a suitably chosen material different from the first roller), and due to the triboelectric effect the belt then gains a negative or positive charge (opposite to before).citation needed] Flypaper loses its effectiveness over time when it dries up or becomes covered with dust, and it should be replaced regularly. Great for barns, houses with chickens, and more, this trap can house thousands of flies and doesn't need to be changed for 30 days.

If flies are ruining your outdoor activities, the original Flies Be Gone Fly Trap is a convenient, inexpensive, and easy way to reduce their numbers quickly.Catchmaster Clear Window Traps are perfect for catching sunbathing flies at one of their entry points. We also found it to be effective very quickly, in fact, we spotted flies trapped inside an hour after installing it.
