Scented Wax to keep the asshats away?

Hi,

There's this wasp sized gap in the frame of my bedroom window that I can't use any permanent means to seal. (College apartment housing) There was a yellowjacket problem because of a nest nearby. Last semester dozens of the yellowjackets got in the apartment and multiple bastards woke me up at odd hours of the night by stinging me. Really fucked w/ my anxiety and I spent hours and a lot of money looking for humane ways to deal with the issue.

I blocked the gap with triangular prism crystals by shoving the smaller part in. I previously tried cloth and cinnamon oil, but they still got in. They should have a hard time burrowing through crystal. But I also want to deter them with scents. I have some scented candle wax that is mainly cinnamon, but it also has clove and vanilla. Will this work?

Edit:

TLDR: Would a cinnamon, clove, and vanilla scented piece of wax deter wasps?
