I know the answer is going to completely gross me out but I have to ask. Where the h*** do fruit flies come from?

There's no simple answer really. But mostly, dampness. Any stagnant source of water (like a rarely used drain) is a breeding ground for them. Do you have an infestation?
If you do, the only thing you can really do is be patient. I brought a lab home with me for a long weekend (the lab was a fruitfly study), they got out and I ended up with fruit flies EVERYWHERE. I was going nuts, I would set up "traps" and then when they weren't expecting it, come and attack them with sprays. But their life cycles are short, so if you get rid of breeding grounds, you'll prevent future progeny. If you suspect a breeding ground, cover it with saran wrap, and tape it down, they will come to the surface.

Ewww. My brother is a vegan and they have incessant fruit flies. Not fun. I say just get rid of anything fruity from everywhere but the fridge and you'll be rid of them very quickly.

I don't have a problem or infestation I am just curious to know where they come from. They seem to come out of nowhere.

Probably eggs on the surfaces of stuff and then when the conditions are right, they start to grow. I should know this one, but I never cared much for fruit flies... Ask me about Daphnia instead... :D Their eggs can stay dormant for centuries... They swim with their "antlers". (sorry for the hijack, I got carried away.. :o )

Here I found this:

"They're native to most areas of the country," says Colorado State University entomologist Whitney Cranshaw. "They come from outdoors."

They come when they smell your peaches rolling across the ripeness line.

Fruit flies prefer a diet of yeast, that marvelous microbe that eats fruit and spits out alcohol. Since flies disdain unripe fruit, and since that is precisely the sort of colorful paperweight that supermarkets tend to distribute, it's more likely that your Drosophila melanogaster came from the great outdoors than from the grocery store.

Here's a fruit fly FAQ page... They can become addicted to crack... :eek: :D

LOL this is from a site about cultivating fruit flies...
Caring for your fruit fly culture is very easy. Basically, you don't have to do anything. The fruit fly culture is completely self-contained and needs no cleaning or special care.
I can hear it now... "My fruit fly is itchier than usual. Could it be allergies?" :D

fruit flies are every where here, yo ucant excape them, we jsut try and eat the fruit fast replacing it with fresh as often as possible.

the fruit flies are so bad ehre you cant travel between states with fruit and in NSW you cnaq only go half way up the state with fruit, they search your car if their suspicious, but most ppl are good. its funny when you drive through the fruit fly zones you see heaps of ppl on the side of the road eating their fruit so it does not go to waste, i do this also, but try to plan trips and fruit so i dont have to eat a bag of apples at the border or exclusion zones... :D

That's messed up mel. Canada is so huge and I think we are free to travel with whatever in our vehicles-- except maybe open alcohol and illicit drugs... :D. Well, and maybe not rats in Alberta... :D

oh no its for the good of every one. basicalyl this is a huge country, we have many industries that would be devistated by the fruit fly, such as our bananas and apple industries.

certain growing areas have worked hard to minimise fruit fly in each area to protect crops, the last thing they need is me sneaking in an apple that has eggs and then getting into their fruit.

even if you fly you msut get rid of fruit at the airports...its basically like state to state quarantine.......and so far has provwen effective, we have minimal outbreaks here which is great (ah except in my kitchen) :eek: :D

We also have travel restrictions here in the US. I'm not sure if there are any others, but anyone travelling into California gets stopped at a checkpoint and asked about fruit.

I still think they are on it, the lifecycle is so short that everything moves at high speed. If there were eggs on it and it was left out they would hatch very quickly.
