The only non-herp products I use for herps are:

Deli cups (as water dishes in my rack)
Nix (diluted in water to make a mite spray, I was in a pinch)
Travel blow dryer (to warm f/t rats right before feeding them)
Kitchen scale
Tupperwares for soaking snakes in
Salad tongs (getting things out of the cages of aggressive snakes)

That's about all I can think of for now!
