if you have spider mites you can treat the surrounding area's with a product called suspend SC look it up on the net,..mix .25oz w/ 1gallon of water and spray on soil lightly...it'll take about 1 week to knock them out but they will die...also you can look into a product called cb80, it contains Pyrethrems which will kill on contact... not sure if it's safe with mj but I spray it on nadle plum bushes etc, doesn't hurt those..just be careful...also soap and water will kill them (50/50) you really have to be careful. just read the label,..if you need any help w/ bugs message me..I'll help. peace out
