There is a few good way just depends on what stage your at look up and research dr.doom and einstein oil those sorta things will work good
i keep two wolf spiders in my closet garden. they took care of my spider mite and black gnat problems and now im growing insect free. best thing is, they only eat meat and dont spin webs around my ladies.
Well the ladybugs are a mite killer on there own so you shouldn't have used both what did you expect I had spider mites on my last grow 3weeks into bud and that was my only option at that point because you can't spray the plant Down with other chems so sorry if you had Abadan experience with it. Dr doom worked for me and worked well use it once then again 3 days later to kill off eggs that hatch JMO
but soome neem oil...spray the plants once a week with the neem mixed with water. it will take some time but get rid of them.. the perythen bomb work good but you have to get three and bomb every three days until your out of bombs.. then follow up with neem.. the plants love the neem anyway so making a habit of spraying once a week is a good preventive measure..
Unfortunately my pet Rose Hair Tarantula is to big for a spider mite problem. I had a spider mite problem about a month or so before harvest and needed to get rid of them fast so I used Azamax. It works great and is safe to use right upto harvest day.
