Every once in a while I hear the rumor that wasp spray is great for self defense as a pepper spray alternative. The theory is the long stream allows it to reach far and in a precise manner. I’m going to say it up front, this is false and this rumor needs to stop.
Wasp spray does not have anywhere the same amount of “stopping power” as pepper spray.
Here’s a very conclusive test showing the differences between a tool designed for self defense, and a tool designed to deal with insects.
When it comes to trusting your life in a self defense tool, only trust tried and true methods, not hearsay rumors on the internet.
