Reoccurring Spider Mite Problem

The last three or fours harvests out of the place im living at has a horrible spider mite problem and i need help. We've been bombing with grow and bud bombs. Been spraying with azatrol and now we got some shuttle, really hardcore make your skin boil(literally, ouch) shit. None of it works. Lady bugs just die when they come near the plants, 0nly the mites survive. I need some tried and true ways of getting rid of these a holes, I don't want to see my babies suffer anymore..

If you turn a room off between harvests, in the cool or cold environment, Spider Mite just sleep happily, dormant, waiting your wake up and feed "next crop".

If you keep a light on, turn off all fans, let it get real hot, they all hatch, spray them down or stick in a sacrificial lamb [spare dope plant...] for them to infest and spray the place down every other day with a strong mix of Insecticidal Soap.

If you are having ongoing problems with Spider Mites, I guess you are spraying with water and insecticide, not water, insecticidal soap and insecticide, you must use the soap to reduce surface tension and actually get the whole leaf wet. You will never kill all the spider mites without it.

Just one month ago a mate destroyed a SM plague with a 1x application of Torque. So as to not F--- about, he had the room all hot and unextracted for a week, then I arrived and made up the solution in a bucket and dunked the babies directly in it, upside down, right to the stem base. Not one SM has shown up since.

good drown

there are some other kinds of bugs that eat spider mites, they sell them on amazon.
why do the ladybugs die when they get close to your plants? that may be a problem since you are going to smoke these plants
im guessing you use soil, and that how they come in each time.
 
hmm. i'd like to try the dunking its seems like the best way. Shuttle can't be purchased around here without a farm or nursery license. I stepped on a drop of the diluted mix after it had dropped on the ground and my feet and legs got boils all over them, its really gnarly stuff and since it can only slow down the spider mites progression, im getting a little worried

is your room sealed? do you have CO2? up the CO2 ppm to 8000-10,000 and nothing but your plants will live through it. not even you. do not fall asleep in your grow room during this process, or you will not wake up.

seriously, though... this method is 100% effective.
 
the room reminds me of an intel clean room and thats how i've been intending it to be. I have 10mil plastic cover on floors with panda film coating everything else. It makes it nice to clean between harvests, which i thoroughly do, but they seem to keep coming back. It all happened when i started working on a commercial op. the mites were like impervious to everything, They guzzled the azatrol and took baths in neem oil. and then a security leak led to having about half of the plants crammed into various places around the whole house....now im cursed with SM!!!!!!!!!!!!!!! smoking as we speak, FML!!!!!

I used neem oil when I got them. I used 2 oz. of the 70% conc. per gallon and sprayed all plants from every angle until they were thoroughly soaked, massive dripping, and after 4 days did the same thing to kill the hatched babies. If you don't spray again you won't get rid of them, you have to spray again after 4 days.

I haven't seen one since, Neem oil is cheap too.

Yes floramite is the best option, but if you do it you must do it right, we dont want mites building up resistance to floramite like they did to avid.
 
You could stick an ozone generator in the room when the plants are down for 2 or 3 days - but make sure there are no living things that you want to stay in the room and turn off all extractors/inductors as ozone is pretty dangerous stuff. It will kill the spiders, and you dont have to worry about smoking something which gives you boils when you take your next crop down.

You might be having a problem with them getting behind or under all that panda-- Believe it or not, you will get better reflectivity if you take it all down, and paint everything flat white--
Then I would use floramite....or try another one I heard is very good, called Judo--

Floramite is the best at killing SM =i have used it for a couple years and have hardly seen any mites,I spray the plants down before going into flower room if they need it or not

for predator mites to work conditions have to be perfect i guess, I tried everykind(before i found floramite) and nothing helped,ladybugs were a joke>if anyone has had luck with ladybugs lemme know

I've never tried any of the systemics, I'm just too scared. Neem oil works wonders, but results vary hugely depending on the technique you use to apply. One friend has great success washing both sides of the leaves by hand. He sort of holds a bowl of solution under the leaves and dips and swishes them around. Getting the undersides of the leaves soaking wet is the main point. Dipping works great when the plants are fairly small. You can also dip with a stronger than stock solution (let stand 5 minutes) and rinse after with a water dip.
 
I've tried everything in the book for spider mites. The only thing for clearing out a room that works 100% is filling the room with co2 to kill them off.
