We live on a lake in central California. There is good news and bad news. Good News - the lake is brim full this year. Bad News - mosquito heaven! We needed some relief if we wanted to enjoy the warm evenings unmolested. This baby rocks! I hung it off the eves about 6 feet from the ground between our house and our friends next door. After reading the instructions, warnings, and some of the other reviews, I did not use the attractant they supplied just to see what happened- I could always add it if needed. At first (May) it was getting just a few bugs, but now (July) holy moly!! I kid you not, in the morning (it's on a timer to run 5:30 PM to Midnight) the entire grid is totally packed with mosquitos. We couldn't believe it the first time it happened! We had no idea there were that many critters! The big plus is we can sit out side and enjoy it now, both on our side seating area as well as our neighbor's back patio. This thing is a keeper! Dead mosquitos by the thousands! I love it!
