Amazon.com Review:
Flowtron's lantern-style insect killer uses nontoxic ultraviolet light to eliminate mosquitoes, biting flies, and other insects over a 1/2-acre area. The insect killer is cleaner and safer than its chemical counterparts, and its patented nonclogging killing grid eliminates the grid clogging that can short-circuit the unit or cause flare-ups of insect remains. The insect killer features high-impact construction and a protective outer enclosure to prevent children, pets, birds, or wildlife from contacting the charged grid.

Rating : - It works, but not very efficient
I used this insect killer for fruit flies. After an entire night, I found some dead flies and the condition was better,but that's only a little part of all the flies. By the way, this thing is so noisy...
