Its not all that effective for mosquitoes. Moths sure, it's effective. But I fully wasn't expecting to trap a sparrow. This bird suffered. While I'm not a fan of sparrows, I'm wholly against inflicting suffering. This is a huge design flaw.

Such little bulb so important to a bug zapper, easy installation!

Hi All, So I bought this thing back in 2017 and I'm just now writing a review because I'm absolutely frustrated with the, not poor performance, but the no performance on Mosquitos. I bought this unit because I live in West Texas and I am sick and tired of being eaten alive by Mosquitos. Hooked it up and it caught tons of moths at our old house. My wife finally had me take it down because it wasn't working. Well here it is in 2021 and we bought a different house. This year for some reason we have had and continue to have a very wet summer and the Mosquitoes are out in droves. For example last night I went outside around 7:30 PM, (still light outside) to clean the pools filter, (maybe 10 minutes total) and in that short period of time I was bitten 15-20 times, (nothing like itching bumps all over to encourage a restful night of sleep). So I decided to try to hook this thing up again to see if it works. So I got it out of the garage and hooked it up in the back yard. Now you did read the part where I said there are Mosquitos in droves, like clouds of them. The unit ran all night long and it caught a ton of moths, and a few other little bug, but it didn't catch one single itty, bitty teeny, tiny Mosquito, NOT ONE!! This thing is total junk, and it does not work as advertised. I see some positive reviews, not sure where those are coming from, maybe the Mosquitoes are smarter in West Texas. Somebody should probably sue them for false advertising PLEASE do yourself a favor and avoid this device like a plague of Mosquitoes. And it's not cheap, I paid $110.00 dollars for it. Itchy in Texas Update: I called the company prior to posting this review to see if maybe I had a defective unit or if there was something I could do to make it work better. They only suggestion is that I buy their expensive packets of attractant to try and lure mosquitos into the trap, which of course even if it works has to be replaced every 30-60 days. I read reviews of the attractant and a lot of people claim its worthless. This device is a complete scam and I am considering filing a complaint with the BBB and other consumer protection agencies. I will never buy another product from DynaTrap again.
