fuel vent cover - slip on
 
could be an option for Summer flying to keep the big bugs out.

slip on fuel vent cover

Certainly *looks* cooler than my little discs of aluminum window screen, prosealed on my vent openings. Not sure it would be as effective, though. We have bees & wasps in my area that are quite adept at plugging a 1/8" hole.

if it is plugged, pop it off, throw it away, put on another and go.

You must not have the same critters in your neck of the woods. The ones down here start building several to many inches up the tube, and work their way out.

Besides, the whole point is to avoid the plug.

Not sure about Mississippi mud daubers, but I've found their Virginia cousins are completely stymied by a piece of safety wire bent in the shape of a large bobby pin (for friction retention) and shoved into the pitot tube. Easily pulled on preflight like a dipstick to check for mud/bug guts - but I never see any.

Like Charlie I have screen mesh over the fuel vents, but I think the wavy safety wire trick would work as well. I had several instances of aborted takeoffs due to invisible wasp clogs in the pitot before I did this. Fuel vents had screens from day one.

screens and this plastic piece can freeze in the Winter. Better to have it open in the Winter.

Screen insert
 
Steve,
For those who are concerned about smaller insects, they could also embed a micro screen between the plastic and the vent fitting.
