My helmet fits fairly snug to my head size, so I tore out the pads and velcro and wear a Headsweats sweat-vac skull cap. The skull cap helps protect my fairly bald head from the sun, and gets washed a couple of times per week. I have a bunch of these so there is always one dried out and ready for use. This would eliminate the "spider hiding under the helmet pad" problem too. I hang my helmet inside a bike locker at work. I have not seen any critters inside, but you never know.
