I’ve got lots of parasitic wasps making themselves comfortable on my balcony.

NOPE, not in the 5 star insect hotel I crafted JUST FOR THEM 😤

Last year, I removed a few screws I had drilled into the (gypsum?) wall, but was too lazy to also remove the hollow-core wall plugs and fix them.

Some wild wasps saw the opportunity and moved in, taking the burden off my shoulders to do the job 🤷

Now, I’d like to restore the wall to its old glory, before my landlord catches me doing stupid things 👀

But also absolutely don’t want to harm any innocent bees or other friendly critters. I want them to move out when they’re ready.

I also think many just didn’t make it, but I don’t know how to check that.

When would it be the best time of the season to seal them off?
