Avid, and then 21 days later
Floramite, but don't use in flowering. Insecticides wont work, as mites are not insects, theyre arachnid family.
Avid/
Floramite have a 28 days effective period.
Mites have a 21 days breeding cycle, and this shit will wipe them out, on the first hit if you spray correctly/thoroughly ( follow all directions ). 2 applications are recommended of these 2 chemicals. If anything happens to survive the first treatment ( Unlikely ) the different chemical makes sure there is no immunity to said chemicals.
This stuff also will kill many other types of pests, and is safe to use. 1 place on Ebay has a deal of buying a small amount of either 1, and get the second chemical free. So if you buy 5oz Folramite, you will also get 5oz
Avid, FREE. Can be had for around $30.
Dont mess around and waste your time.
Avid/
Floramite WILL TOTALLY ERADICATE THEM. Until you reintroduce them again. I would also spray anything suspect before I would introduce it into a garden.
CAnt say about any of the other stuff, as Ive not used it.
