I haven't had to repel bees yet, but I've had to repel or deter other animals. The mothball recommendation comes up now and again, but I haven't had success with it.
Pack rats are very common where we live. I've got a running battle with them in the garage. If I make the mistake of leaving anything loose on the work bench, it will vanish in the night, only to turn up again months later when I clean out a pack rat nest from some hideaway in the garage. And for some reason they love my wife's pick-up truck. During the spring and summer they regularly try to build nests on top of her engine block, and equally regularly chew the wires off the distributer. Pisses her off big time.
Anyway, several people suggested mothballs as good repellants, so we tried it. What we discovered was that the damn packrats would just carry the mothballs back to the nests. Probably helped them control fleas or whatever, but it sure didn't scare the rats away.
I've heard of mothballs being recommended for keeping dogs and cats out of gardens, but I've also heard stories of dogs digging up the mothballs and cats completely ignoring them. I think the mothball manufacturers must have an advertising agency that promotes goofy uses of mothballs.
My favorite repellant story, though, involves a wolf and some hot sauce. I had a couple wolves, and tried to plant some trees in their yard. But the trees (in 5 gallon pots) would get chewed down and dug up as fas as I could plant them. Someone suggested Louisiana Hot Sauce as a cre for the problem. Sounded good to me, so I got some hot sauce, diluted it a little and put it in a spray bottle, and planted the next tree. As soon as the tree was in the ground I soaked it with hot sauce. Meanwhile, the male wolf walked up and watched the entire process. When I stepped back, he went up and sniffed the sauce-soaked tree - and licked it a couple times. Then he walked over to me, sniffed the spray bottle - and started begging for it. Might as well have doused the tree in salad dressing as far as he was concerned. I gave up on the tree planting - figured there were enough trees there anyway.
