Dude! Sucks! I’m very sorry to hear that! I’ve gotten to the point where I just assume they are present, but dormant or my weekly IPM is keeping them at bay.
Im still using Nube’s spray and haven’t seen anything in a while. I make sure to hit them weekly in veg. In flower I got nothing. Actually, I remember colocowboy over on riu mentioning spraying flowering plants with alkaline water, then acidic water on rotation daily. Never tried it, but sounds like it might keep populations low enough to get through harvest.
