This ingenius, hulking, $200 electric mosquito-catcher can nuke 1,200 bloodsuckers a night:
The trap uses a strip of octenol (to generate a scent that resembles breath), a UV bulb, and flashing LEDs (oscillating frequencies determined to coincide with spectral sensitivities of many mosquitoes). When mosquitoes get close to the trap, the patented airflow system that disperses the attractant sucks the insects inside, where they are collected in a mesh catch bag or a liquid catch pan that is easy and safe to empty.In a USDA suburban test, our trap captured up to 1,200 mosquitoes in a single night and diminished mosquito populations over an entire acre.
Update: Mr Jalopy sez, "this homemade carbon dioxide yeast brewing machine sounds like a great way to lure mosquitos to their demise. Same premise as the aforementioned $200 device, but without the 'LEDs oscillating frequencies determined to coincide with spectral sensitivities of many mosquitoes' which frankly sounds like bullshit to me."
Jonderson sez, "The advertised rate of 1200 bugs per night is not even half of what one single bat will eat (roughly 3000 per night). Put up a $10 bat box and you can virtually eliminate mosquitos from the area entirely."
Update 3: Scott sez, "That bats will eat thousands of mosquitos each night is a myth:
Studies have shown that while bats devour a huge number of insects,
mosquitoes are only a small part of their diet. A study of fecal pellets of
bats in Indiana conducted throughout an entire summer revealed that the
primary food items were beetles, moths, and leafhoppers.
Update 4: David sez, "There are over 1100 bat species worldwide, making up some 20% of all mammal species. Some bats eat fruit; other bats suck blood. Some bats (in Indiana) don't eat a lot of mosquitos; other bats in the Southwest eat tons."
