Set a trap. Apple cider finger mix dish wash detergent stir and let it sit by in a container where they are all at. They get attracted by the smell then hit water and sink.

I tried something very similar, did catch a bunch, but not all of them, and then they multiply so fast 😭😭

Came here to say this. Took a few attempts but it's an absolute bloodbath when it works. Counted over a hundred after a week
