Thank you! I'll have to go to one of the nurseries shortly and see if they have some of those available.
As of right now, I have a bunch of milkweeds growing around the raspberry bush. They appeared on their own, and although they're in some weird spots, I leave them there because the pollinators love them so much. I just put some materials in that area two days ago as well, in hopes the carpenters will find some use in them.
That area of the yard is admittedly a bit messy, but there's always a literal cloud of different insects hanging out over there in the warmer months, so clearly they're happy with it how it is. I had some more honeybees over there the last few days, and a few different butterflies.
There is another large bush nearby, though I'm not sure what kind it is. On the other side of that bush, is a corner with a small tree. I think I'm going to dig out that corner for a pollinator garden.
I like having the little carpenters around. They haven't been problematic in any way so far. Once in a while one finds it's way into the house, but it doesn't bother me. I just scoop them up and return them outside.
Aside from being fun to watch, they do an excellent job taking care of my fruits and vegetables too!
