Where do fruitflys come from?

Question

We just got back from a week away on vacation, and we left a small amount of fruit on the counter. When we came back, there were fruitflys all over the fruit. My question is - where did they come from? There were no fruitflys in the house when we left, the windows were all closed, and no one has come in the house for a week. Did they just smell the fruit getting old from outside the house, and then travel from a neighbours house? Where they in the fruit the whole time? Do they hide in a corner of the house, waiting, hoping for fruit to get old?

Answer 1

you should always wash your fruit before eating.Because the eggs are already on the fruit before you buy them or pick them.Wash them really good and don't leave lying around as this causes the fruit flies.They are so hard to get rid of.Try putting a wine bottle with a bit of wine in the bottle,on the counter they will fly in there and you can cork it and get rid of them.
I hope this helps.

Yeah fruit flies. i'm in a Drosophila lab (fruit fly). The eggs have already been laid on your fruit and fruit flies have a incredibly short technology time. After the egg is laid and it takes a pair of million day at room temp. (25C) to hatch right into a universal instar larva. that's a universal instar larva for ~ a million day, then 2nd instar for ~ a million day, and 0.33 instar for ~2 days. It spends this time merely eating nutrition and turning out to be. in the time of late 0.33 instar the larva will crawl to a drier section and pupate. It continues to be interior the pupal point for ~5 days. Then it ecloses into an grownup fly. those flies additionally attain sexual adulthood after basically ~4 hours from eclosing.

the eggs are laid on the fruit whilst it is still growing in the fields
