Question: what happens if you block a wasps nest?
Answer: DO NOT BLOCK THE ENTRANCE TO A WASP, HORNET OR BEE NEST! Blocking a nest is one of the worst ways to deal with a wasp problem. By doing this, the wasps are confined in a tight space and will quickly become agitated. If blocked in, wasps can chew through plasterboard, wood, and various other materials to find a way out.
