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?
I doubt the holes are big enough for wasps, maybe not even for bees. But if so: Bees are likely to stay, wasps might move on in autumn (?) So, without harm, it depends on who came to live there but maybe without harm isn’t an option. You could wait until it seems abandoned and fill the holes then.
I’m having wild bees in my hotel and they come only in periods and don’t stay
Really depends on the type of bee
Many wild ones are solitary bees
