Wasps can attack people and the Bulldogs who own these people. Learning to understand these pests is the first step in being able to control them, while at the same time, enjoy their benefits. Hornets, Yellow Jackets and Polistes may sting, if you go near their nests. Mud Daubers and Cicada Killers usually will not sting unless you touch them or get them caught in your clothes. The various chemical poisons on the market can be more harmful to you and your bulldog when used in controlling the various species of wasps.
Some states have restrictions on the use of certain pesticides.
If you haven't yet been convinced to use more natural forms of control, it's important to check with your State and or local Extension Service to learn what regulations must be followed. The various traps that are on the market are quite good, but expensive. Homemade traps are just as good, cost next to nothing and are simple to make. They can be a fun and useful craft project with children. I've tried several wasp bait products on the market, and yet find one to work as well as my homemade method.
