Fruit Flies a problem?

Just wondering if fruit flies would eat the plants. We have a big fan inside the grow room, and my brother did point out the idea that they wouldn't be able to fight the fan power. We don't have hundreds, but a can of food or a beer gets left out over night every so often and we get a few. -_-

What do you think?

Make a fruit fly trap with a wine bottle and a sheet of computer paper... they work slicker than puppy shit...

+Rep for your speedy help, im just not sure if I understand how it works.

fruit flies are generally fairly benign, but the same conditions that breed them will give rise to fungus gnats (which look really similar at first glance). <-these guys lay their eggs in your soil, and the larvae munch on your roots. a good way to tell the difference is that gnats are generally a little bit smaller than fruit flies, and look black compared to fruit flies which are generally reddish brown.

Roll the bright white paper into a long skinny cone and put about 2 inches down in bottle neck... it will uncurl but remain a cone.... flies are drawn to wine but cannot figure out how to get out... they will die a fairly quick death... in a day or two...

what a great idea^! (i've always been 'small hole in saran wrap' myself, but this is better!)
my MIL told me if you put a couple drops of dishsoap in the wine/vinegar/fruit juice left in the container it coats their wings when they try to drink and they drown quicker so i do that too.

Do the flies perefer red or white?

i don't think it matters. other stuff that works are wine vinegars, balsamic, sugary liquers, beer, fruit juices (<-although these can mold so you have to change them everyday).

well now that i'm 'able to roll a joint' i'm gonna go do just that....

I heard about the beer thing, put a small dish out with a little bit o beer in it and the flies will start to come. I did just that and I dont think it attracted anymore flies than the yellow fly strips I was using, but maybe these flies dont like canadian beers ( it was Labatts) maybe I should try some real American beer like Yeungling or something? And personally I would rather drink the wine as opposed to give it some gnats whom I despise, I mean I would rather drown in wine myself and just poison those little fuckers LOL!
