What are these?
 

Showing up on a couple place on the house- very hard to remove

Mud wasp nest and pupa

Yup, mud daubers, they make nests in our garage and behind our shutters. They don’t bite and are harmless but make a mess. Hit them with some wasp and hornet killer and wait a couple days and scrap away their nests and sweep up the remains. Easy peasy.

:eek: the other day I went to clean off a couple of these where the wasp had left and there was a hole in one end. A nasty looking spider had taken up residence in it and startled the heck out of me.

Actually the wasp puts the spiders into the mud tube so when the larva are growing they have something to eat.

Invasion of Body Snatchers...run away

They DO bite. Even though Wikipedia says they rarely bite, and only if they feel threatened, I’m here to tell you they can feel threat if you even approach there area and have no idea they’re there. I went to water my plants and got bit in the calf. It was painful and I had a welt on it for most of the day, though I sprayed the area with alcohol. That’s when we noticed that we had a nest on the eaves above where the pots were.

They can also nest in your bushes. We find a nest every once in a while when our landscaper trims...

If you don't like using wasp & hornet spray, Mix two tablespoons of dish soap into a cup of water and spray; the soap plugs their breathing pores and kills them nearly instantly.

Daubers

Yes they absolutely sting .. like a wasp

Look like mud daubers nests. Very common.

THX! great tip i will use next time, i'd not heard of that 1 before

i use a spray bottle of water and a tooth brush to remove the nest.
