Wasp and swarm traps.

[Stlnifr]

If a wasp takes up home in a swarm trap will the bees still try to use it or will they leave it alone because of the wasp.

Will the lemon grass oil be a deterrent to the wasp and keep them out of the trap

[AllenF]

Wasp and bees do not get along.  If wasp take up, you take them out.

[Michael Bush]

The bees won't move into a wasp nest.  You will need to remove them.  They also won't move into a finch nest (the other thing that seems to move into my bait hives).
