DynaTrap DT1260SR Mosquito & Flying Insect Trap with Pole Mount (1/2 Acre) $65 + free s/h

I picked this up from Costco in late spring and have been using it the past few months. At this price, I would suggest picking it up.

Like others have mentioned, it doesn't target mosquitos as well as the advertising makes it seem (they're not particularly attracted to UV, mainly CO2). However, depending on placement, I have found that it can be fairly effective at cutting down on their reproduction rates, especially when used consistently over a month long period.

When I placed it between my house and my patio area, it caught a metric boatload of bomber beetles and moths. Occasionally I'd have a fly or a wasp, never seen a bumble or honey bee or some of the more beneficial insects. While it does catch a large number of insects aside from mosquitos, most aren't really that beneficial and are also pests (beetles, noseeums, gnats, etc). About the most beneficial thing I've seen are the moths, but they're largely just pollinators and it won't really wipe them out entirely (they have relatively short life spans anyway). Plus, when I empty the trap, I put in in a bird feeder dish / bowl and the birds flock to it and still eat their food anyway, so it's not as big of a disruption to the ecosystem as some would make you think.

When I placed it further out near the woods my property backs up against, that's when I saw a significant increase in effectiveness in catching mosquitos and other pests vs number of beneficial insects, especially if it's an area that stays wet or has standing water. I wish they had a solar powered model which would make it easier to have an ideal placement, but since these require electric outlets, I needed to have a long outdoor rated extension cord to power it back there. As such, I keep it in the spot between my patio and house where I have an electrical outlet. It has cut down significantly on flying insects like the annoying bomber beetle and gnats, and I have also noticed a drop in mosquitos (but don't expect to not see a single one or never get bit). Using this alongside other normal measure like citronella candles or bug spray makes it much more effective and pleasant experience. I'd buy it again just for the reduction of annoying beetles and other insects.

I've also seen people using attractants to make it more effective, such as people placing fruit in the basket or mosquito attractant.

everything except mosquitoes.

Did you manually strip and search all your guests for mosquito bites?

Remove the light. That is the most dumbest thing. Good insects are attracted to it. Go online and find a reputable reseller of Lurex3, Octenol, or R-Octenol consumer mosquito lure/attractant. R-Octenol is the best if choosing just one.

If I had the time, I would build my own bug zapper focused on mosquitos. No lights. Large electrified zapper cylinder, 3 foot diameter, 6 feet tall, black. Lurex3, Octenol, or R-Octenol release tabs inside. 20lbs propane tank hooked too a windproof igniter with auto shutoff nearby to spread CO2. Bye bye female biting mosquitos. Collapse the local water colonies.

ok well most people have neighbors.. and they arent going to like the loud zapping ALL NIGHT long especially during the summer time when some people like to sleep with their windows open.. just sayin

Then you probably live in a city location zone with noise ordinances. Like dog barking. So you couldn't use a zapper after a certain time anyway.

Have you tried fogging your area? Might not be perfect but it does lessen. Do it like one a month or after rain.
