Where do fruit fly's come from?

Question

Whenever I buy strawberries they appear about 2 days later, do they look through the window and tell their mates to come along or do they already have eggs on the strawberries when you buy them? YUK

Answer 1

entoaggie is right about the strange places that they can breed, like sponges and any wet moist environment. check your garbage, compost, and unlikely places like onions (they looooove to breed on onions) and other vegetables. if your windows are open and they smell the fruit then they will just fly on in (you know that Shania Twain song, "Come on over, come on in, eat up my berries, eat up my fruit.."). there is a chemical (I think it is ethyl acetate) that they are strongly attracted to. there is nothing you can do about it if they are coming from outside except close your windows or screen them. you can provide a diversion for them (a big bottle of vinegar, wine, or orange juice does wonderfully) and they will even get stuck in there and drown.

btw, it's impossible for the fruit flies to come from the strawberries themselves. it takes 10 days for the egg to develop into an adult fruit fly. and I don't think you would have bought strawberries that had pupae all over them (hmmm.. these strawberries have a nice nutty crunch to them.. ewwwwwww. :-)) p.s. why don't you put the strawberries in the fridge?

good luck

Answer 2

You could be bringing them in on the strawberries, if they are from a farmer's market or organic vendor. From a grocery store, though, that is unlikely, as their produce has usually been treated and thoroughly washed.

You might have an infestation that began elsewhere. They'll occur in the strangest of places...I once experienced an infestation in my old apartment that I could not track down the source of. I threw away all exposed food, cleaned out the drains, and yet there were still fruit flies everywhere. I was at my wits end...then, one day, I noticed a little wiggle in my sink sponge. Turned out the flies were laying eggs in the sponge, and the maggots were growing up in the moist environment, feeding on the food scraps that came off the dishes. Talk about gross....

Answer 3

they arrive from eggs that were laid by employing fruit flies. The eggs are contained in the fruit. The eggs are microscopic, so that you won't be able to see them. before the discovery of microscopes, scientists fairly theory that fruit flies come from fruit and that maggots got here from rotting meat. yet whats up... they used to imagine that the international develop into flat and that the Universe circled round the Earth.... the following is a sturdy technology challenge. educate that the Earth is round. arise with conclusive info. you may in basic terms use gadgets that are latest in a classic kin .... (and also you would possibly want to't use an encyclopedia or a laptop. you need to go back up with the info on your own. The Greeks did it over 2000 years in the past... imagine you may?)

Answer 4

The eggs are on the fruit when you buy them.
I am fascinated to hear that there are people who can keep strawberries for 2 day.

Answer 5

As the people above have said they are attracted to overipe fruit. They are the simplest of fly there is unfortunatley they breed like crazy but don't live long. I think they are called "Drusilia".

Answer 8

fruit flies are outdoor flies they wait for fruit to just pass over the ripe stage and then they come in lay their eggs. if you go to discovery.com "skinny on skinny" there is a good answer to this question.

Answer 9

They certainly enjoyed my home made wine. They usually appear around this time of year, as things begin to rot in Autumn and they get turned on by this - says a lot for my wine, but it kept me afloat for weeks....................
