The western yellowjacket is a versatile wasp. It will nest in the ground, in tree trunks, or under the eves of porches. As with most of the creatures around, I tend to adopt a live-and-let-live approach. However, when this yellowjacket bars entry through an occasionally used doorway by attacking visitors, I draw the line: the hive has to go.
Western yellowjacket wasps are building a hive on the lintel above an entrance doorway, and then terrorizing all who dare to pass by. This is war.
