i use them, they seem to be a good preventative measure, another thing you can do is get a shopvac of the sort and it sounds crazy but if you have a severe infestation you can just stick the hose around your plants and suck the bastards up, after you do that, fill your tub up with COLD water and flip your infected plant upside down and submerge everything green and then kinda shake the whole thing underwater, they get shocked and they will fall off from the shaking, sounds corny, but it works ..... follow that up with a sns -217 treatment ( all natural) , then a week later give em a shot of azamax... dont forget to clean your grow area top to bottom with a mix of water and bleach in a squirt bottle, spray everything ! , rinse and repeat and you are on your way.... cleanliness is next to godliness... peace, happy killin
p.s. everything i just wrote is in the event that you notice spidermites in veg, i would not spray a budding plant with anything.... i have done the submerge method and the other treatments with clones i get from shady characters who dont give a fuck about mites, i do,,, they suck balls
