If you are dry(who isn't) and have any Spidermites I would throw the threshold advice out he window. Spray now, don't wait. You are going into a weekend, by Monday you could have a mess. Spray the headlands and around waterways at a minimum. The inside could be ok. If it was me I would spray everything.
Spidermite threshold ?
