Here is the easiest way I have found to keep Spider Mites and other predator bugs out of the growroom, without using other Predator Bugs or pesticides or mixing an organic solution in the kitchen.
Go to a Pharmacy and buy a spray can of Lice Spray " like RID or Store Brand " the active ingredient is " Pyrethrem. "
This is a plant compound and yes it has some petroleum in it, like most things these days, but it is a lesser evil, that will keep everything away for the entire grow and do no harm at all to the plants or you and is cheap and available anywere........Pest Strips are extremely TOXIC and should not be used for your plants and especially for you.......dichlovorus, the active ingredient in Pests strips is a horrible toxin!
Simply spray the outside of your pots with this spray and then spary some on a napkin and wipe the inner base of each pot, above the soil line.
works every time and you do not have to spray it thick as a little goes a long way and will leave a slight dry film, that will kill just about any Predator Bug, that crawls across it.
