If you want to raise fruit flies get this:
- apple vinegar
- lots of sugar
- baking yeast (or brewing yeast, doesn't matter which one)
- (optional: potato stuff, bananas, other fruits)
Put everything into a plastic cup, mix it properly with a teaspoon, then put some cotton on top of the mixture (so the fruit flies have a place to sit on) and use a nylon sock to cover the cup (after you've attracted around a dozen fruit flies).
This recipe is foolproof, doesn't mold, rarely gets mites and the fruit flies love it. It'll take a few weeks to start rolling but within 3-4 weeks you'll start getting a ton of fruit flies.
I use a similar recipe I got off the internet to culture my flightless fruit flies. I was wondering what the purpose of the vinegar was. Does it help with mold prevention?
The recipe I have is bananas, apple sauce, white vinegar, oatmeal. I used this recipe because I had all the products on hand. I know there are many variations to this recipe.
fruit flies are also known as vinegar flies. they just like it.
That is the first time I ever heard them referenced as that.
