If you are deeply troubled by insects, our insect killer will be the perfect choice for you! The mosquito killer attracts insects into an electronically charged high-voltage metal grid and kills them without exception. Plus, it does not use any chemicals, so it's non-toxic and odorless, which is great for babies and pregnant women. Simply place the lamp against mosquitoes as close as possible to the insects and light it, then it will do the rest of the operation. No assembly required.
