For the price, a "Wasp and Hornet Killer" promises a 20' ling jet and seems to be a good alternative to comparable sized pepper spray (or bear spray for that size),
e.g. $6 for Enforcer-16-oz-wasp-hornet-killer-spray vs. $40 for an 8 oz. can of bear spray.

However, the MSDS indicates that it is largely a petroleum based solvent (>95%) - sort of like kerosene - and the rest is the active systemic insecticide, which does not sound promising for the purpose of repelling bears and dogs.

Has anyone experienced the effects of being inadvertently sprayed by Wasp killer or paraffin based paint thinner or kerosene? Of course, it will not compare to Capsaicin but would it be sufficiently irritating and blinding to escape a bear?
