I think I can blame the cherries for my fruit fly infestation. I plucked some ripe cherries and carried them inside in a plastic bag. I cut one open and taste-tested it. Yuk! Sour! So I decided that the birds could continue to eat them. Trouble is, I forgot about the bag until all these nasty little flies starting turning up. I discovered the bag about three days later (don't ask), and tied the top in a knot and put it on my garbage to go out. Somehow the little, um, larvae got out, so I had to bag everything up triple before putting it out. Eww! I have the creepy-crawlies just thinking about it! I tried the yellow sticky mats. I hung one on a hook to one side of my sink. A couple days later I came home from work, and I notice my Ragdoll sitting by the back door looking pitiful and not wanting to move. When I tried to examine him he walked away, and he had the yellow sticky mat glued to his butt! He'd also somehow gotten a plastic grocery bag glued there, too. And he'd been walking around all day like that. No wonder he felt pitiful. I bet all the other cats were laughing at him.

If they are tiny gnats. It's more likely that they are fungus gnats. Too much water in the soil causes the right conditions for these things to thrive, let the soil dry out. Also do a search for fungus gnats on GW for treatment options. Also as Kevin stated identify then treat. Mark This post was edited by habjolokia on Sat, Nov 16, 13 at 12:56

what really worked for me is yeast. i noticed that the fruit flies really liked to hang around bread. so i proofed some yeast (overly warm water, sugar, and yeast) amounts don't matter, but don't be too stingy on the sugar. i also found that when i put the mixture in a medium blue bowl vs white they were way more attracted. i also kept a spray bottle nearby, and would spray them into the mixture as they hung around the sides of the bowl. i must have got thousands over a month. change the water/yeast mixture when there are too many fruitflies. plus once the yeast has proofed, spray it down a bit or stir it so that the yeast isn't frothy on top. excuse the lower case - i have a broken arm. carol

Sadly, my digital camera is busted. I was hoping the description would seem familiar to someone... guess not? If I can lay hands on a camera from a friend, I'll see if I can post an image.
