hornetSome hornet species can look similar to yellow jackets, but hornets are larger and thicker. Hornets are slightly less aggressive than yellow jackets and like most wasps, hornets can sting multiple times with a very strong painful sting. Hornets build warped ball shaped nests the size of a football or soccer ball in eaves, attics, and building, including bushes, trees. It’s generally considered unwise to try to remove a hornets’ nest without experience. While most hornet species are yellow and black, there are also white and black hornets.
