If you ride in during the summer (who doesn’t???), there may be times when you’re putting bug repellent spray on.
DEET-based products harm synthetic fabric, so opt for a DEET-free bug spray if you don’t want any surprises.
I’ve used picaridin-based products, and they seem to work as good, if not better, than DEET.
If you use permetrin on your gear/clothes never let cats sleep on them - while they are fine with low doses higher ones are much more dangerous to them than to us.
