Just a thought. Check your helmet before you put it on particularly if you leave it in the aircraft.
Insects are on my preflight list now.
You are absolutely right. Just like the cowboys in Westerns shake out their boots before putting them on to prevent scorpion bites!
I have had a cockroach in my helmet, but not because of storing inside the helicopter, of course. But a bee in my bonnet I haven't suffered fortunately. Flies in the cockpit are a distraction, especially on short finals, or in bad visibility, when you want to pull cyclic to avoid what you perceive as a bird.
Any clues on how to reduce spiders weaving their webs in the cockpit and cabin, anyone?
