Any organic options to be rid of them?

I’ve posted this several times but I don’t think many are using neem oil. Cuke beetles and powdery mildew used to be my nemesis. The last two years I’ve sprayed weekly and by mid July no cuke beetles.
It works two ways- it makes the beetles “ think” they are full after taking a bite and it also interrupts the life cycle so they can’t reproduce.

You mix a tablespoon of neem oil and a few drops of dish soap in a quart / litre of water. A little goes a long way.
