Features:

• INSTANT INSECT ATTRACTION & ELIMINATION: This bug zapper emits a 365 nm wavelength, which has been scientifically proven to be highly attractive to insects, as it falls within their natural viewing wavelength. As flies, mosquitoes and any other flying insect can't resist approaching the light source, they get immediately zapped.
