Why wasp spray should not be used for defense
1. There’s no research to suggest wasp spray would stop an attacker.
2. Using a pesticide in a manner other than according to labeled directions is a violation of federal law (the Federal Insecticide, Fungicide, and Rodenticide Act).
3. It is illegal (finable offense) for anyone to recommend a use other than the labeled use.
4. Personal liability is likely to be significant for a person who deliberately sprays another person with a pesticide.
5. Pesticides such as wasp spray have not been tested on humans. Direct human toxicity data comes from records of accidental exposures and suicide attempts.
6. Poison control records document an amazing number of people who have accidentally sprayed themselves or innocent bystanders when using aerosol cans. An emergency situation may exacerbate that reaction.
No successes?
So, yer sayin' you'd be better off just to shoot them.
