Bumpy also has screens for the ports and me bought screen material last year by the yard at our local harware store "PINI" and fashioned a few screens for our forward hatch and companionway. However, I am also going to buy a few double wide baby buggy bug nets for about 10 dollars each. they have elastice around the bottom so can pull down over an open hatch. It was suggested that you could weight them down with fish weights pined on the bottoms or buy cheap link chain and glue to the bottoms to hold in place.
also, I read that you could spritz the screens at night to deter bugs from heading in that direction. We don't use lights that much at night. Book lights and battery candles to keep the light low.
We also used the bug fans and they did seem to work, but I will try one down below, or hang just inside the companionway.
I also found these patches, I think at REI, that looked like a giant bandage and no smell.
I was told that mint oil and eucalyptus oil work well in wax burning candles, but I think I am going to try the products that were mentioned above. I know I will smell good.
