Another use for wasp spray that I learned in the medical field is for protection against criminals. I keep a can of wasp spray in my car and in my bedroom. If sprayed at an intruder, aim for their face. The wasp spray will temporarily blind them for at least
five minutes giving you time to flee. Unlike pepper spray where you have to spray up close, wasp spray is meant to be sprayed at a distance of 20 to 30 feet. This is good to know if you break down where you may be unsafe.
