Query: Cost me a buck a bug.

It killed a few mosquitos, but very few and at a very high cost.I live in the NE, (Massachusetts), and ran the unit from April to fall. Moved the unit trying to find sucess twice, but never saw the catch bag more than a third full in a month of trying. This season the cost of propane is $22 a refill and the bottle has to be changed less than every three weeks. I get a big grin from the guy I buy the bottles from, and I'm probably going to hell for what I'm doing to global warming.Mosquito magnet is very over-rated.
