Should You Get Rid of Mud Dauber Wasps?
Mud daubers rarely sting humans and only do so if handled roughly or attacked. For this reason, it is often advised to leave them alone and not get rid of them. They get rid of flies and spiders and are generally harmless to humans. Birds also get rid of the mud daubers naturally. But if you do decide to eradicate them yourself, they are the easiest wasps to deal with because they don’t attack in a swarm like the more “social” wasps that protect their nests do.
When deciding whether to get rid of them, consider whether their location is near enough to human traffic that it causes an annoyance and whether the benefit of them getting rid of the spiders is worth having the daubers around.
