@Myfriendis410 has a good method for controlling spider mites 
Here’s what @Niala suggested months ago and it works:
Spray the entire plant with a 50/50 solution of distilled water and 3% peroxide. Pay particular attention to the undersides of the leaves and the soil surface. If you have a fabric pot, spray the pot too. Wait 48 hours then apply “Captain Jack’s Dead Bug”. It’s a bacteria toxic to pests but takes about 5 days to work. Leave that on for 5 days then repeat with peroxide/water and so on.
Once you have them you should plan to treat for them. They are in your area and you will never really get rid of them. This is the most benign and effective way to kill them and is safe all the way to harvest.
@Sutton @MattyBear You can purchase in other products other than Captain Jack’s Deadbug Brew contains Spinosad "spin-OH-sid. Spinosad is derived from a naturally occurring soil dwelling bacterium that was collected from an abandoned rum distillery on a Caribbean island in 1982. This unique bacterium was defined as a new species when it was discovered and it has never been found in nature anywhere else in the world.
Since being discovered, Spinosad has become a leading pesticide used by agriculture world wide in the production of organic produce. Today, thanks to Captain Jack’s Deadbug Brew, Spinosad is available to the homeowner.
