| Fruit flies |
This time of the year, when your counter if full of ripening fruit and the compost bin is loaded with peelings, seeds, and all the residue of the wonderful produce available this season, we find a problem pest flying around. That annoying little creature we call the fruit fly.
Whitney Cranshaw, Colorado State University Cooperative Extension Entomology Specialist gives us this information about the fruit fly.
"Vinegar flies, also known as small fruit flies, commonly develop in overripe or decaying fruit and vegetable matter. They are minute, light brown flies with orange-red eyes and rarely are they found very far from the fruit bowl. Numbers tend to build in late summer. If conditions are suitable and food is present, they may breed indoors.
Although associated with fruit, developing vinegar flies actually feed on yeasts. To eliminate a vinegar fly problem, use up overripe fruit, refrigerate it or discard it. At the same time, give attention to other breeding sites. Vinegar flies may, for example, breed in the moist residue that remains in the bottom of beer bottles or soft drink cans, as well as in other areas where moist organic matter allows for yeast growth. After all such food sources are removed, some residual adults may remain for a week or so, but ultimately will die out."
Also clean sinks and drains, empty indoor compost pails and set out baited traps. Here's and article on how to make your own fruit fly trap: lancaster.unl.edu/pest/resources/fruitflytrap.shtml
