Getting rid of flies is a wonderful idea. Almost every day now, a fly gets into my room with the computer. It flies onto and in front of the screen and annoys the heck out of me.
Let us know how well this machine works. Also, it seems to trap the and not kill them. The machine says "Electronic Fly Trap" so is there a zapping element in the central chamber?
Good luck with this.
Another idea, why don't you hang a mosquito net over your door when you open the door. That will keep most of the flies and other insects out.
No, there is no zapping element. You either release them outside or allow them to starve to death in the chamber.
