Fruit flies lay eggs in the skins of fruit, including bananas. When the bananas are ripe, that’s the signal for the larvae to eat their fill and molt into flies. Bananas release ethylene gas when they’re ripe, which signals the flies to hatch and eat, as well as signaling other fruit within range to complete the ripening process.

Fruit flies have a very short life cycle, so if you don’t provide anything else for them to lay eggs in, they die off when the original fruit is gone.

this subreddit hasn't been for that for many years. it's just for good explanations. there's no requirement that you use a slick metaphor that kids would understand. it's explained in Rule 4

Fruit fly like banana. Born from banana. When no banana, no fruit fly.

Most times the eggs of the fruit flys are on / in the fruit. Leave it too long and the eggs will hatch and you will get flys. These are harmless and fine to eat, infact you have probably eaten hundreds of fruit fly eggs in your life.

Or consider this, you have eaten many bugs and you're still alive. Hunter-gatherers can survive on bugs and they're fine.

Show them whose on top of the foodchain (and rinse your food).

Thank you did not realize this. Does washing your fruit not rinse them off?

Fruit fly trap - mix a little vinegar, water, and dish detergent together. Leave it out in the open. Worked for me.

when fruit ripens this creates vinegar, fruit flies are attracted to vinegar because this usually means ripe fruits are near, when the fruit flies disappear I just assume they've left to search for another source of vinegar
