Organpipe Mud Daubers are pests.

These wasps create larva rearing mud tubes in which young develop. The Organpipe Mud Dauber nests occur between brick and wood trim and resemble organpipes. A female will typically lay several eggs in a single pipe and will have three to six pipes per nest.

Most Organpipe Mud Daubers feed on spiders.

If provoked this wasp uses its stinger.
