These “things” are adhering to the stucco on the outside of the house. They are very hardy. No amount of hose spray will bring them down. I have eliminated other things like wasp nests before. Never seeing anything like this.

Dear Bugged in California,
This looks to us like a Mud Dauber Nest. Mud Daubers are beneficial wasps that are not aggressive. There is no need to hose it away.
