Home made fly trap ingredients?

[Enchanted]

I used a 1.25lt soft drink bottle and added...

1 cup sugar
1 cup white vinegar
1 banana peel

Then fill the bottle up until it's 2/3rds full and give it a shake. Then take the lid off and hang it from a tree, they said it will take around 1 week to ferment. Ours has SO many flies in it and no smell

Maybe I didn't put enough banana in? Hmmm, will tweak and see what happens.

I saw that honey one too - am going to try it
