Once you’ve done all of that, you may want to use one of the below control methods to minimise the risk of a future infestation. Remember to check up on your plants daily and to repeat treatment at least twice to avoid having the mites coming back.
Next, create some extra air circulation in your grow area. Spider mites hate windy conditions.
Once you’ve pruned your plants, consider hosing them down gently. This will help remove any remaining mites and will also help prevent another infestation. You may want to hose them down periodically if you find you’re dealing with mites on a regular basis.
Remember, spider mites like hot and dry conditions. So, before you get started on any kind of countermeasure against a colony, try bringing down the temperature in your grow room (if possible, bring them down past 20ºC or 68ºF but be careful not to damage your plants).
