JORGE'S RX: Spider Mites!
Fri, Oct 01, 2004 3:32 pm
Thank you for all the assistance from your books and articles in HIGH TIMES that have helped me grow medical marijuana under California’s Proposition 215.
I have a 6’ x 8’ outdoor shed that I divided into flowering and vegetative rooms with a 400w HPS lamp in each. There is an exhaust fan, a Green Air Products propane CO2 generator and the room stays between 80°-85°. My first crop was beautiful, but the last two have been inundated by spider mites. I tried BANG (pepper-based insecticidal soap spray) and a solution of isopropyl alcohol and water. The plants are looking better, but the foliage is damaged and buds are suffering. Even after cleaning the entire space with bleach and repainting, the mites are getting back through the intake duct.

Dear Grimace,
Spider mites are worst in climates such as yours that seldom freeze. A freeze kills most eggs outdoors, and dry air from a heat system keeps their reproductive cycle slowed down. Your attention to cleanliness must continue. Put a very small mesh silkscreen over the intake, and wet it down regularly with insecticidal soap. Mites have a very difficult time passing through a miticide-treated wet silkscreen. Smear Tanglefoot (a sticky trap gel) around other possible unsealed small entrances. Spray all around the shed with a strong miticide, to lay out a demilitarized zone. The all-out war starts inside for any mite that is unlucky enough to enter.
Always dip clones in miticide before moving them into the flowering room. There are quite a few miticides available that work well. Two of the best are aerosol pyrethrum and neem oil. My favorite brand of neem is Einstein Oil. The trick to killing spider mites is to make sure the spray touches them. Tilt plants up on their side and spray leaf undersides where mites and their eggs reside. Miticides approved for food crops must come in contact with mites and eggs in order to kill them. If spray only touches the top of foliage, mites are not affected.
Keep the entire room clean at all times, so there is nowhere for mites to hide. Inspect for mites daily and spot spray anywhere you find them. Eggs will continue to hatch for weeks, and new mites must be killed before they get a chance to lay more. Keep up a rigorous eradication for at least 6 months, and you should have the problem well under control.

but if you wanna be a pro mite-slayer, dip your clones in floramite right after they root and before you put em under the big lights. then treat with einstein oil mixed with dish soap every couple weeks, and spray with floramite again right before you flip to flower. through the first 20 days of flower, keep neeming em with einstein oil and NO dish soap, it wont hurt the taste or fragrance of your flowers, believe me. just dont treat within the last 2 weeks. and if you really wanna go crazy, get tanglefoot or petroleum jelly and smear it all over the stalk of every plant (mites get caught in it and die trying to get up to the rest of the plant). you also HAVE to have a silkscreen over the intake sprayed with floramite so the bastards cant get in your room. wear a lab coat into your room every time and hang it outside your door so you dont brush the mites from your friends' gardens and your front yard hedges all over your plants. predator mites, in a big garden, take up to a year to take control, and if you're doing 4 runs a year, this is unacceptable. ladybugs do little to NOTHING, dont listen to hippies. pyrethium works fine if you're bombing an empty room, but as for the spray, its not very good. as for the strips.. are you kidding? maybe for some little kid who can dip his 3 plants in ice cold water every day and chant his plants to sleep might find a couple mites on the strip every once in a while... MAYBE. and there is NO electric device that kills mites in a whole room, what you're talking about is a deionizer, and they DO help with mold (a little). ive never tried c02 for mite control, but im guessing it doesnt work, ive never heard of using it for mites. the only way to kill mites, at least up in mendo/humboldt area where the mites are mutated to super-mites is to spray them with crazy poisons and chemicals. this is from YEARS of experience, and it is correct. we've tried everything and this is the only way that works PERIOD. chor boys up, custies down!

They're cheap and efficient. Just try to keep them contained if your grow is indoors. Don't want 'em all through the house, believe me.

look at the leaves, the first noticeable sign of SpderMites are little brown spots on the leaves....
have a good look on the underside of the leaves, you should see little orangey dots or black dots, they sometimes move, these are spider mites.
A few ways to get rid of them.... if you are still in vegetive then a good bug spray will be fine. Grab each stalk from the bottom running your hand upwards, this exposes the underside of the leaves and spray.. dont be shy, drown the fucker. Repeat 3 days later to make sure you get the eggs, also to be sure I usually do it a 3rd time....also a good folier feed, I use wormliquid and soda water, will help the plants to recover
if you are in flower, I found the best way is to consult your outdoor garden... Lady bugs are spidermites worst enemy they will eat eveything, eggs and all. A few lady bugs in the grow room will devour all mites with in days.... This is the BEST method and one I use when I get them.
Prevention is better than the cure... mites only usually get into the room from you.. so be very careful in future entering the room. Also mites usually come from around the house , check your garden around the house and treat them too...

sprinkle cinnamon on the floor, helps reduce mite's and ant's and other critters from traveling across the floor.
Garlic spray works but not on the eggs....Pyrethrins sprays work but leave a residue that makes some people feel run down when smoking bud sprayed with it....Dish soap works ,add a few drops or more to a spray container of water.Spray plants in the veg room..don't spray buds with this mixture... Dish soap also leaves a residue on the leaf.Wash or toss the leaf.

"No-Pest" strips DO NOT work on mites (read the label). They can't fly.
GC mite is good too, if you want to spray.

'vapo-strips' are like no-pest but are impregnated with a gas-off poison. avoid these- they're toxic.

tear everything out and bleach or hydrogen peroxide the shit out of the space. then heat up the room for a few days empty. this'll speed up their life cycle, make'em all hatch and starve to death. you could use a bug bomb after a day or two i guess but i don't really like them; pretty nasty. the longer you leave your room fallow the better. two weeks minimum with lotsa heat the first week. your environment must be spotless: no refuse around or hiding places.
then get a decent intake filter and treat it periodically with miticide.
if you can't afford to shut down and your plants need it now:
'end-all' is a great pyrethum based concentrate that is sprayed on(observing good spray technique : under sides). it is the only product that i've seen work completely. everything else just beats them dowm a bit.
'avid' is a nasty systemic. it is illegal in some countries including canada. i have seen it used over a year or so and the mites did build up a tolerance to it (damn darwinism). best avoided.
'neem' is nice and organo but is relatively slow and ineffective. it's also kind of a bitch to work with. warm it up a bit and add some liquid soap (just a few drops per litre) or it will seperate. oil and and water.
shake your spray bottle constantly between spraying.
pyrethums (sp?) are derived from crysanthemums. look for concentrates and mix it up yourself; the aerosols are pricy in comparison but convenient
good-luck and cheers from BC

Avid costs $150 for a 50ml bottle but you only need 3-4 drops in a 1 quart spray bottle full of water....
wear rubber gloves when applying the chemical, spray in a well ventilated area and apply on young plants because it takes 2 months for the chemical to dispurse out of the plant spray top and bottom of leaves spray

BEST TIME TO SPRAY IS ABOUT AN HOUR BEFORE LIGHTS TURN ON.IF YOU CANT DO THAT THEN TAKE THEM OUT OF THE LIGHT SPRAY LET SIT TILL DRY AND RETURN TO LIGHT. IT IS KEY TO SPRAY UNDER THE LEAVES. MITES LOVE TO CHEW ON THE VEINS OF THE PLANT SO BE EXTRA CAUTIOUS. SPRAY EVERY ETHER DAY FOR TWO WEEKS. AFTER THE TWO WEEKS SPRAY 2 TIMES A WEEK FOR A MONTH. AFTER THE MONTH IS UP SPRAY ONCE A WEEK. THIS PROCESS SHOULD TAKE ABOUT SIX MONTHS. THAT MIGHT SEEM LIKE A LONG TIME SO DONT GET DISCOURAGED CAUSE IF YOU DO THOSE LITTLE FUCKERS WILL WIN.
HAPPY GROWING THE GROWTECH

The insecticides are ok in growth cycle, I won't use them in flower. I couldn't get rid of the little f_______. Then I realized I was carrying them in myself. I used to carry water in milk jugs, let it sit to be rid of chlorine. I got rid of them and always take water directly to rooms. Once got a bad infestation and used jugs filled with water, they crawled in and drowned. Finally got rid of them for several years, this year because of company I had to break up Mothers' room. Stupidly set them outside during day and in flower room at night to get 24 hours light for them. Guess what? I have spider mites again. I'm going to try the flour and milk recipe, too late for chems.
Keep it clean and be careful about what you carry in and good luck.

1. 1 gallon water
2. 1 cup allpurpose flour
3. 1 cup milk
Mix together very well, pour
into a squirt bottle, lay plants on side and spray UNDER
THE LEAF. Spray once daily for 2 weeks on all plants. Make sure you keep the rest of the mixture cold until use.
You can use it until the 2 week of flowering.

The only sure cure is Floramite..
it should work with just one application..do not spray once flowering starts and if you have to do not spray for 21 days before harvest..
please wear propper gear for protection..

get a hand full of the spiciest pepers, dried out and ready to eat. a spoon full of vinegar and a spray bottle full of clean water...get a bowl, add the vinnegar and a Quart of water,grind up and throw in the peppers. leave over a day or so...REMEMBER. you need about 5-10 peppers...After the next day spoon up the solution and add it in your spray bottle, and mist your plants, more in affected areas... ALSO WORKS ON HUMAN HAIR WITH LICE OR HAIR MITES... FOR ALL YOU DREAD LOCK LOVERS... this technique should keep your plants chemichal free, tasting great ready to smoke...

1. Buy a one gallon sprayer
2. Buy "Shultz" professional bug spray. In yellow bottle, look under active ingrediants, make sure "Pyritherans" is the active ingrediant.
3. Buy "Neem-Oil"
4. buy dish soap.
5. Fill one gallon sprayer with 3/4 of water.
6. add one big or two small bottles of shultz. This will kill bugs.
7. add four tablespoons of neem-oil. This prevents ability to breed.
8. add one tablespoon of dishsoap. This aids in thick neem-oil distribution over evtire leaf surface.
9. close sprayer. Shake very well before every use. Spray EVERY THREE DAYS, NO MORE, NO LESS.
10. For severe cases use a little more shultz. When you see no bugs, KEEP SPRAYING EVERY THREE DAYS TO PREVENT RETURN, and use a little less schultz.
11. Do not over spray plants, will harm them. Focus half spray on bottoms of plants, other half on top. When you see no bugs, just lightly spray. See bugs spray the hell out of everything. More shultz, harder on plants. Less shultz no problem.
12. This is safe to use up to a few days from harvest. All ingrediant labels claim safe to use on edible vegitables.

First i bushed out a clone to about 1 foot tall and maybe a foot wide, actually thats on the big side but whatever. I put it in my flowering room with no safers soap on it at all. I then put in the rest of my clones with a good soaking of safers soap. Naturally the mites thought the untreated plant tasted much better and completely ignored my new clones and infested the untreated plant. I sprayed my new clones heavily every other day with the safers and the sacrificial lamb weekly very lightly just to kill some but not upset their new home too much. After my new clones where thriving with only extremely managable signs of mites, if any at all, i then removed the poor ravished lady and her new tennants and put her way outside to die alone. I now spray weekly with safers and have a beautiful flourishing garden again with very little signs of pests.
If you have a room with flowering plants already infested, do the same thing, spray your good plants and sacrifice one. Good luck! Legalize it.
