Liz: trust me if this worked I would carry a bowl of water with one of these in it everywhere I went, and a bat and a flock of swallows. My sister in law swears by mayonnaise, when she ventures out she smears this environmentally friendly substance on her face and arms, when she comes back you can see the "#@%?X!! vermin" stuck at the point of entry which is not a pretty sight.

Liz,

My home sits on a quarry/pond. The architect had put mosquito fish in, and I get next to NO bites all year in the area of the pond. However, near my front door I put a small recirculating water feature in a year ago, and I see mozzies there all the time.
