And for anyone who wants rid of wasps,(not supporting killing them for no particular reason) Dawn mixed with water, spray and stomp. It works very fast. We had to clear out about 30 small nests that were in and around our educational birds pens as they were being constantly bothered. It was also a risk to those caring for the birds. It was a safe way to get rid of them and not risk using chemicals around the birds. Spray right on the hive/nest, when adults are at it. They will start to fall immediately and U can stomp them safely.
