There's a good side and a not-so-good side to those annoying fruit flies hovering over the peaches and bananas in the kitchen.

The good side: The three-millimetre-long fly's genetic similarity to humans and its lifespan of 60 or so days helps us study the progress of long-developing diseases.

Dr. Gabriella Boulianne, a senior scientist at the children's hospital in Toronto, says 70 per cent of the genes that cause disease in humans are found in fruit flies.

The not-so-good side: Each of us has probably eaten hundreds of thousands of drosophila eggs or larvae. But don't worry, says Steve Marshall, professor of environmental biology at Guelph University. Flies won't survive our digestive juices.

The flies plant hundreds of eggs on fruit, inside garbage cans or on open wine bottles. When the eggs hatch, the larvae burrow into the fruit or yeasty environment, where they cocoon until they hatch. This process takes about a week and then your kitchen is full of the invaders.

The best way to banish fruit flies, Marshall quips, is to stop buying fruit, since most already have eggs or larvae on them. Drosophila can live for days in the refrigerator. Marshall recommends eating overripe fruit first.

As annoying as the bugs are, we should remember they help turn organic material back into soil, says Cynthia Scott-Dupree, a professor at Guelph University.

Here are six tips to help reduce the population:

-Wash all fruit when you bring it into the house to get rid of as many eggs as possible.

-Put fruit in the fridge during the warm months. Two days in there will kill any leftover larvae and eggs; keep them there to prevent attracting further flies.

-Move organic compost away from the house.

-Wash all recyclables, particularly wine, beer, pop and vinegar bottles, and keep them out of the kitchen.

-Discard rotting or overripe fruit into an airtight container, not an open garbage.

-Clean kitchen drains with bleach.
