I'll BET that's not the first time someone has mixed up similar pump spray containers, autistic or not.
  I use Bullfrog Bullfrog Mosquito coast Sunblock and Repellent in one.
  It's water/sweat proof and doesn't contain DEET.
I carry 100% Deet for worse case scenarios, but the Bullfrog will do the trick most of the time and having then combined simplifies things.
  I don't want to be bitten alive or burned while on a trip. Either one or both can make for a miserable time :(
