I have a bee story to contribute to Bee Watch, but fair warning, it will give you the willies...
In 1984, my parents bought an old Victorian house, but it was a fixer upper. It had been "in the family" for years, before the family decided to sell it, so it really hadn't had any upkeep for years either. Well, there was a secondary chimney from when there used to be a fireplace in the kitchen back in the "olden days." Since the chimney was unused it became a yellow jacket's nest for who knows how many years. So my Dad calls a few exterminators who come out and say, "They can't do anything about it, it's too dangerous, try a beekeeper." So he calls a couple beekeepers who come out and say, "It's much too dangerous, try an exterminator." So this back and forth continues, until someone suggests a "bee bomb" that my Dad could place in the bottom of the chimney, and that it might take a couple.
So my Dad gets the bee bombs and carefully opens the door at the bottom of the chimney in the basement. And it's all clogged up with dead bees, bee droppings, old parts of the nest that had fallen down. He emptied tons and tons of 5 gallon buckets of bee crap. Puts in a bee bomb, come back a couple of days later, and has to empty more buckets of dead bees. Looks at the chimney and it doesn't seem to have had an effect on how many bees are flying in and out of the top of the chimney. Three or four bee bombs later, and finally, no more bees flying around. So at that point, my Dad got up on the roof with a 10 ft pipe and started jamming it down the chimney to break up the nest. He thinks it must have been about 8 ft deep. So of course that was who knows how many more buckets of bee crap that had to be cleaned out of the bottom of the chimney.
And the fun thing, they came back the next year and tried to rebuild the nest so he had to do another round of bee bombs, and finally got it all cleaned out.
