Avid and Floromite vs Spidermites!!!!!!

Hello all, Ive just got me some Avid and Floromite to take on and kill these little buggers that are trying to wreak havoc on my babies.

My question is, what do i use first? do i use them together or what? i know to how much to mix but does anyone have any thought on how best to tackle these mites?

thanks all
