Let us know. I love gadgets that zap stuff. Put dunks in our barrels today. 3 do not seem to manage well with the screens, and the blood-suckers are thick in there. We store over 2000 gallons for our market-garden/CSA sideline.I might try one of those thermacell gadgets, that would help on the deck. I have also had someone tell me he got good results with those smoking coil repellent things.
