Wasp and Hornet Killer, Bees and wasps build new nests every year, they do not re-use the old nests.
I had the same problem in my old apartment- they were in my bedroom- I called maintenence and they did all they could do- they vacuumed, sprayed, everything. It was scary- I was allergic to bees. I finally bought a new wall unit with my own money because my landlord refused. I don't think you can do anything else...
