Yellow jackets in a/c box

[HMBdave]

Hello all,

Wife and I had our TH delivered back to our home this afternoon from the dealer and as I was showing the driver to where I wanted it parked, I noticed that yellow jackets were quickly moving toward and into the a/c unit on top. I am out in the country and I have seen these yellow jackets all over my property but I was I bit disturbed by them trying to make a home in the a/c unit.

Does air actually get drawn in from there into the trailer?
Is this something I need to worry about? If yes, what can I do to prevent it?

The yellow jackets often seem to find a home under the covers of the air conditioners. Just a week ago my son had a blower wheel fail and when removing the A/C cover he discovered three active nests. He used some industrial bee spray to kill them. He also pulled the cover of the second A/C and found the same thing in that unit. He was stung once getting rid of those nests.
