@Murph75 - regarding the milk. I was having some mild success with it, but found something g even better. Baking soda + water. Idea is to get the pH above 8 and apply as a foiler spray. I defoliated then sprayed the adjusted water. WPM was gone the next day. Milk worked, but also dried on the fans, so gives you a false positive, and makes it harder to spot any you might have missed.
Both seemed to work, but after some experimentation, I like the basic water spray for WPM in my garden.
Good luck
