actually, we try to control errant Drosophila by taking Erlenmeyer flasks
filled with some Drosophila food (or the occasional banana skin), leaving
them open for a few hours, attracting a bunch of flies, and then capping
the flask and sticking it in the freezer. It isn't perfect, but it keeps
the wandering population down.
