Wasp question (live, mold, best)

[vasleta]

I have had carpenter bees on my porch. This evening, I witnessed a skinny black and white wasp go into their holes and throw out their larvae. The larvae stayed alive for a few minutes and died. What species does that?? I tried googling but came up empty. They were definitely not resin bees.

Update, one of them is in my bee trap. I'm told by an entomologist that it's probably a four-toothed mason wasp.

That's a fearsome sounding name.

We recently installed a new front door, after having the old one for 30 years. The old one had normal wood mouldings but the new one has "engineered" wood (basically sawdust and glue, best I can tell). Never had a problem with carpenter bees in that location before, but the new door had been in only a couple months when I noticed a pile of sawdust. A carpenter been had drilled a nice, neat, circular hole in the brick mold. I'm not sure what made the simulated wood attractive to the bee, when regular wood never did. I have a treated wood top railing on my deck, and carpenter bees seem to love treated wood. You'd think the chemicals used to treat the wood would kill them, but they apparently like it.

Uhh, yeah, otherwise known as the HORNET.

Kill. KILL. KILL!!!

The carpenter bees, while they do drill holes, are much more beneficial to the environment. Wasps and hornets have no real redeeming value. They are a plague.

I only use PVC brick mold now. It's rot proof, paintable, and will last forever.
