Mud Daubers: Gentle Wasps That Rarely Sting

Mud daubers (dirt dobbers) are wasps but extremely non-aggressive. Stings only if handled. They provision nests with paralyzed spiders—beneficial spider control.

Coexistence

• Nests on porches/eaves are harmless.
• Remove old nests in winter if desired.
• No control needed.

You're both right: they're wasps that don't sting.
