These work!!! I had my 2 units 2 yrs before using them; this year we had record numbers of mosquitos, including lots of the large striped black ones. Even with wearing insect repellent, we were getting multiple bites soon after siting or walking outside. I wish I'd used these in prior years - they are awesome!! And no chemicals or zappers! Our property adjoins a seasonally swampy area, and these work!! Reviews recommended leaving them up for a few weeks before expecting noticeable reduction. By the 2nd day, we noticed substantial reduction. We've had them up about 5 days. As expected, we still have mosquitos, but noticeably fewer every day. We plan on leaving them up all season, and are ordering a 3rd unit. Next season, we should see even fewer; we dump about 1/2 cup of mosquitos every other day, and those will NOT be reproducing for next year. And we will hook up the units much earlier in the season. Looking forward to being outside & enjoying our yard this summer!!

As other reviews caution - these units work by drawing mosquitos to the unit; and they do a great job of attracting mosquitos to their destruction - so don't put them close to where you si, putting yourself in the path of the mosquitos en route to the unit

This thing works awesome in fact I'm going to get another one I live on the water on an acre and can barely sit out at night without getting destroyed by bugs now I get hit maybe one or two times I think if I throw another dynatrap in my backyard maybe a small one on my porch it would almost eliminate all of mosquitoes

Best for indoors even close to people. Low noise, pro bugmane and no toxic debris exploded into the air. I placed something in between the uv LEDS and anyone's eyes to block direct view of dangerous uv light. I plug it in to a surge protector to help prevent surges from killing it and to extend its service life.

I had one of these given to me by a member of my family because they thought it had stopped working. The bulbs were burned out that's all that was wrong with it, replace these bulbs and it works great. The bulbs really do work to attract insects

These glue cards are way better than the cheaper aftermarket cards. The have a thick layer of glue that will trap all sizes of insects unlike the cheaper ones that are more like a sticker with a super thin layer of adhesive.

I only buy these real ones now that I've seen the difference in quality.
