My parents bought me the Mosquito Deleto as a gift after I built my pond. I guess they thought the pond would breed mosquitos. (I actually think I have less mosquitos after the pond was built.)
For me, this product is just a waste of propane. I only found about five mosquitos and a dozen other bugs stuck to the sticky paper device after operating it several months last summer. The propane waste is bad enough, but you also have to buy the attractant and the replaceable sticky paper traps - and the refills are not cheap!
It might work better in areas that have higher mosquito populations, but I will not waste the propane to ever use it again.
