There’s even the old Marx brothers joke “time flies like an arrow; fruit flies like a banana”
The fruit fly trap taught to me by an entomologist friend is baited with wine, suggesting the fruit flies want fermenting fruit
The trap: get a plastic fizzy drink bottle; bigger is better
Cut off the top. The cut piece is a cone
Place the cone (the top piece) upside down on the rest of the bottle
Sticky tape the joint
Bait with cheap wine or leftover wine or beer. The bait is poured down the funnel into the trap
Her tastes were revealed in the description of baiting the trap — she specified red wine, but I have tested with various booze and fruit flies have no taste, they’ll go for anything. You could probably extract bait from the sourdough starter you made in lockdown and kept alive despite never making bread after that first try

Doesn’t even have to be actual booze. Apple cider vinegar + a drop of dawn dish soap works a treat.
I guess not everyone has easy access to booze
