Fucking fruit flies
The only reason I'm writing this is because I've seen other members of this sub complain about fruit flies.
I am a very tidy person by nature. I get a rush of dopamine putting dishes in the dishwasher. Despite that I had a super bad fruit fly problem. Google says apple cider vinegar is the way to go but that shit is expensive. A good alternative is to put out bowls of water, regular vinegar and a banana peel. Put a plastic bag over it, cut a few holes in the plastic and within about 72 hours they will all be trapped and dead.
Also you should be eating bananas as much as possible anyway because of the potassium. Sometimes the texture is too much so just blend it up with maybe some peanut butter for protein.
