This unit catches at least 200 insects a night, but maybe 10 are mosquitos, and the balance is small moths and incests that are not a problem. I used the lights and attractant. My unit had a 6ft cord, not 10ft.The unit is hanging under my deck with a good line of site across the backyard. It does need to be located under cover,and not be exposed directly to the weather.I bought the unit 6/25/2010 and I just missed my chance to return the unit in the 30 day return window offered by Amazon.There was no information on where to put the attractant. I placed it under the fan base in the trap area. I will place the next packet by the lights and see if works any better, since I cant return it. I will continue to use Cutter Backyard hose spray insecticide every few weeks to try to keep these Georgia mosquitos under control
