Self Defense: Wasp Spray A Church worker in a high risk area was worried about a robbery while they counted the collection. She asked the police about pepper spray. They told her to get wasp spray instead. The wasp spray can shoot up to 20 feet away and is a lot more accurate, while with the pepper spray, they have to get too close & could overpower you. The wasp spray temporarily blinds a robber until they get to the hospital for an antidote.
