Wasps are nasty, I'm afraid when encountering any kind of wasp—trying to run as faster as possible. I had a nest in the yard. While my kids were playing there, they disturb the wasp nests. It was a horror. My kids were running and screaming that they were coming; they were coming. It was hilarious, and at the same time, I was horrified. Shortly, I had to look for solutions to get rid of them. I read here that the best solution is to buy Viper Insecticide, mix it with water, and pour it into their nests. It worked perfectly.
