Always bag your helmet if you are not wearing it.
Always bag your helmet or put it out of reach of anything that crawls or swarms. I took a nap at a rest stop with my helmet sitting on a picnic table and rode the next 10 days with ants crawling across the inside of my visor and occasionally chewing on my ears to defend "their turf"! They finally all disappeared as I learned whenever they were on the visor to open it up and blow them off. Since then I have always been careful to never lay my helmet anywere it might get infested, or bag it.
Imagine an arachnophobe at 70mph in traffic with a spider crawling across the inside of their visor! Not a welcome distraction for anyone and I would hate for someone to be taken to the hospital because a creepy crawly decided your helmet vents made a great home.

Reason: Needed more dramatic affects!
