One more thing try the sticky fly traps. I had them so bad at one point and those helped a lot.

White wine works too. Plastic wrap over the top with several small holes. If you've got lots maybe set out a few bowls or glasses of assorted bait.
Love the boiling water in the drain suggestion. I'll be trying that.
Good luck!

Last week I just bought "Hot Shots" from Walmart. There are 3 cans in a package and you have to leave the house for awhilebut they work great. I usually set them off before we go to church, open the windows when we come home and go out for lunch and come home to a peaceful house!! It may be a cool house but definitely worth it.

DH found a pretty little fruit fly catcher at the grocery store. It is made out of glass and sits on the counter. It has some liquid that sits inside a little rim that holds the liquid. There were extra packets of liquid that came with it. We always have problems with fruit flies in the summer when we have a lot of fruit sitting out and it is warm out.

I used the Hot Shots hanging fly killers from Walmart -was in a single hanging white piece of plastic. You just hang it where the fruitflies are and that's it. It said for outdoor use - so I opened a window and made sure there was no food out. Within an hour they started dropping all over dead. Only needed it in the house for 1-2 days and they have been gone since. Hung it outside my kitchen door after.
Used this after nothing else was working.

Add a couple of drops of kitchen soap to a small container of water/vinegar. The flies go for the vinegar, but get caught on the suds. I sit several of these in my kitchen and found lots of flies on the suds every couple of hours. I did finally find that the flies were coming from a plant that I had. I sprayed the plant, but finally got rid of it. No more flies. - Cynthia

I have tried almost all of these except the bug bomb because we have a bird that would not make it (ok really I wouldnt' mind if that happened it's a hate hate relationship :) I did get the sticky strips and put them up in our pantry I hope this helps I have not see it this bad!

I use fruit flies in experiments all the time. They are notorious breeders (very prolific). The best trap I ever used was to place a funnel on a jar or glass (in my case a beaker) and add APPLE CIDER VINEGAR. Make sure there is at least 3/4 inch between the tip of the funnel and the top of the vinegar. Those little suckers fly in and can't get out. We use something similar when we are etherizing them except for the ether, of course.

This is one of those cases where you catch more flies with vinegar than honey. They are not really attracted to sticky strips, bug bombs are not a good idea and usually ineffectual on these little guys,

I had a terrible time with those flies earlier this year. Couldn't use sprays because my foster son has asthma--besides you have to spray them directly to kill them :| I tried the vinegar (both cider and white), didn't work. Fly paper only caught a couple -- most of them were smart enough not to lite on the sticky part. Someone told that if you put a penny in a cup of water that would get rid of them. Supposedly this is what they do in restaurants...I tried it--the flies disappeared but I don't know if it was the penny in the cup or all the other remedies I was using... :roll:

We do the dish of fruit fly trap but there is more than vinegar in it I think. They drive my hubby insane so he is the one that takes care of it.
