I do apple cider vinegar and water in a narrow necked water bottle with a few drops of dish soap. The smelly malic acid of the vinegar attracts them, the narrow neck makes it hard to fly out and the soap breaks the surface tension of the water so they drown.
Boiling water down the sinks also kills them as they breed in there
How are you making them?

I’ve done apple cider vinegar and oil this time. I did a shallow container this time because none of the traps in tall glasses I made worked.
I might chuck it out and start again with the water, vinegar, and soap. When I’ve used oil I think I’ve put too much in and covered up the smell
