I do not envy your situation. Get a few tiki torches and use an oil like this. This is the kind of thing my family used to do and it should help at least ward them off. Other than that, go full scorched earth tactics (BURN EVERYTHING) or wear a bee suit.
That's shitty man. Try the torch and let me know how it works for you.
For the fuel for torches I guess I'd start by looking at using fuel for tiki torches. Not sure how it would work in a bowl but whoever you're getting for your pyro work should know.
