Screen all entrances for 24 hour. Duct tape any cracks, etc.

No bees get out. No wasps get in.

If it is extremely hot, use a division board feeder or bottle top feeder with water.

After 24 hours, the wasps lose interest. Open reduced entrances then. Or better yet, make a robber screen for the entrance. Michael Bush has descriptions of robber screens. Also good info on robbing, which applies to wasps as well.

Yellowjackets and robbing by bees becomes a shark-like feeding frenzy very fast. Stop it immediately.
