Really the only game in town for refills but they work. Last 3-6 weeks. We keep our 'trap' by our pet water bowl to keep the mosquitoes from laying eggs in it. (yes ... ew!) My plan is working! No complaints or regrets.

These are great, the only part that is gross it the clean up. I've seen a noticeable difference in the number of mosquitos. I live in a heavily wooded, tree, shade/bush area (see pictures). My biggest recommendation is to make sure you get rid of any sitting water that reduced our problem by 50%. I had to drill small holes in our roof gutters as they weren't draining completely. Another issue I think some people who complain about it not working need to read how to effectively deploy these. I put this device in areas where I get flocked by mosquitos (it's near our pool equipment, prior to deployment I'd get 10-15 on me within seconds) but about 20ft away from where we will be. Most mosquitos don't travel more than 25-40ft from where they hatch. The instructions say to put this 20ft from where you will be, so I put this in vegetation that sits near the pool where I think many of the mosquitos come from. I then went on the other side of the pool and put another Dynatrap about 20ft from where we would be. I have a huge yard (1.5acres) so I figured having two would be enough. We get a TON of bugs, fyi. The mosquito lifecycle is around 6weeks so for maximum effectiveness this needs to run for 5 more weeks but I'd say I'm happy with my purchase. Remember that these are only as effective as how you deploy them! Also make sure the area doesn't have a competing light source. So this is in an extremely dark area at night with no other light so it is a huge beacon. Good luck.

It catches mosquitos with lure packet but does get other bugs unfortunately. I keep it near my deck so I can check it daily. It didn't catch mosquitos until I added a scent packet which should come with it, imo. I did have to save a few bees but overall it does get some of those pesky bloodsuckers. It took 2 weeks to start attraction attracting them. Very quite machine with purple led light. You do need to plug in. Moths definitely like it!
