Holy cow! This thing is amazing! If you ever wanted the power of Thor, the God of thunder, to zap all those pesky bugs and mosquitoes out of the air. You can't, but this will do. After the first few nights of using this bug zapper, I went out to check to see what it killed, 80-90% of the bugs killed were mosquitoes (that I can see). I'm sure there are many others that dropped onto the ground. It is not as loud as most people would like you believe about electric bug zappers. It sounds as loud as any of the birds in the trees make. I didn't even use the mosquitoes attractant that was provided and it still kill a bunch of mosquitoes. I'm contemplating buying some more and put it around the yard. This is the best!!!
