I had spider mites a couple of times. I think because I had an outdoor veggie garden and tracked them inside. I got pretty paranoid about it and stopped wearing outdoor shoes to visit the indoor grow, and in summer I was even changing to pajamas before visiting the indoor girlz. Monterrey garden insect spray (active ingredient Spinosad) kills them during veg, but I wouldn't want it on my flowers. I tried vacuuming the webs and bugs off the colas, which works to knock the population down, but causes windburn. Smoking a few bugs is better than smoking chemicals.
