FRUIT FLIES

The humble fruit fly is useful if you want to do genetic analysis, but it is a right pain if you live in an ordinary house in a Danish summer. Being so small, it is almost impossible to keep them out of the house if you buy fruit of any kind. And because they lay so many eggs in a short life-cycle that lasts only a few days, one fly can quickly lead to a lot more.

My wife attempted a solution today, whereby she opened all the windows in the kitchen and hoped that the strong wind would blow the fruit flies outside. It failed.
