    Ok, so I am writing this in an attempt to cover the bases on treatments and cures for our most common enemy the spider mite AKA the borg.

    Spider mites are tricky little creatures in the sense that they can sneak in undetected, and build up a considerable army before being noticed. they can track there way in on people, plants, animals, wind, etc.

    The problem is that these little buggers have the uncanny ability to
    A. reproduce
    B. stunt and eat the hell out of your babies
    C. become immune to different treatments and chemicals that we throw at them.

    Now it seems that the key to beating the borg is continued treatments with multiple different kinds of chemicals and oils.. I am going to outline the various treatment methods ..

    at the first sign of spider mites you should take action, and it is advisable to take precautions even if you do not have any that you can see.

    If you have clones the best thing to do is get a bucket of WARM water and make a combination of neem oil and safer soap or additive free dish washing soap. You want the water to be warm so that the neem oil will break apart and mix throughout the water. DO NOT dunk your plants in until the water has safely come back to room temperature.

    The safer soap will not only act as a wetting agent to help coat the plant but also weakens the exoskeletons of the lil buggers. The neem oil will make them immobile so they cannot move and suffocate them.

    Dunking is the most effective method while they are smaller because it coats everything from the ground up, but this is a very effective spray as long as you dont have super mites.. we will get to that later.

    You should spray every three days, the undersides of the leaves or dunk every three days depending on size. This is the most eco friendly and safest method of treatment. This is what you should try first.

    Next which for some works wonders for others not so much is pepper spray.. Many people will put one tablespoon of cayanne pepper in a 9 part water 1 part additive free dishwashing soap to make a pepper spray, or you can buy some at the store called hot pepper wax.

    This works pretty well as an added weapon to your brigade to help combat the lil buggers especially if you have the red spider mites. I do not know exactly why this works but I would guess it is because it gives them indigestion and they shit themselves to death.. (kidding)

    then we have diatomaceous earth which is basically like fossil dust which is very jagged. it cuts the spider mites apart as they crawl across it and dehydrates them. I have personally never used it but I hear it is really good for when your plants are in veg. You do not want to use it during flower because the particles will stick to the bud and can cut up your throat and lungs if you smoke it! you will want to mix this with some form of wetting agent to help it stick to the babies! This is also a good preventative measure because it can be put on top of the soil at the base of your plants and kill any pests trying to crawl up on your kiddos!

    next is pyrethium bombs. These are the foggers you can buy that vary from .0012 percent to commercial grade 4.0 percent. You can use these up until about week 4 of flowering then its not really safe to use. These bombs usually work pretty well after a couple of foggings but recently I had a group of mites that were not even phased by the 4.0 percent bomb... You have to get out for a few hours and turn of ventilation when using these so they can do their job. you DO NOT want to breathe this shit it is no bueno.

    then there is floromite and avid. Never used these either but these are mite specific insecticides and can be quite costly. they kill mites in all stages of growth and are safe to use in early flowering. many people swear by these products while others say mites are becoming immune to these formulas as well!

    lastly we have nicotine tea which was brought to my attention by Seamaiden. I took 15g of organic tobacco, steeped in hot water over night, added a little bit of safer soap and had fantastic results! killed all but a few of the . I dont know if it kills the eggs as well I will know that in a few days. I used this after using almost all of the above and works the best because I had the super strong genetically altered two spotted mites. you can use it at least 4 weeks into flower and supposedly longer without any harm. do not mix it too strong because nicotine is toxic to all living organisms!

    That is about all for now I will update later as I get more info and feel free to chime in with your experiences with these little bastards!

    also knowing what kind of mite you are fighting is a good start. if you have a microscope and you can see if it is the red mite or the two spotted mite (has two black or dark colored spots on either side of its abdomen) you will know what kind of a fight you are in for. As i stated earlier the red mites are pretty easy to get rid of especially when using neem oil and cayenne pepper spray.. the two spotted mite on the other hand needs constant battling with many different approaches. the latter are the ones that grow immune to different treatments

    FLoJo Well-Known Member

    neem oil.. dont use vegetable oil i dont think it will do any good

    Seamaiden Well-Known Member

    Excellent thread, FloJo. I think it should be stickied or something so that it's among the top hits when people do their searches. It answers a LOT of questions very thoroughly. :)

    edux10 Well-Known Member

    that is a nice vert garden in your avatar.
    do you have a journal?

    FLoJo Well-Known Member

    Thanks Seamaiden, I always see threads about this and you dont always get the right answers so I figured there might as well be one so people can share what they did to kill the borg!

    and yes edux Its in my signature..

    GrowTech stays relevant.

    good thread ruined by a crappy title LOL - seriously though, nice post.

    FLoJo Well-Known Member

    haha I am not much for titles I guess, just wanted it to draw attention and get straight to the point.

    anyone have other suggestions for what has worked for them other than what is posted?

    UPDATE: Also found another home made recipe on IC Mag that I will test out on my isolated plant tomorrow to see what kind of damage it does to the scragglers and eggs that are still present. Read a little further down and there are 2 more recipies that were tried as well as results

    1/4 cup Baking Soda
    1/2 cup Apple Cider vinegar
    1 Tablespoon Lemon Juice
    2 drops dish detergent
    1/4 Teaspoon Epsom Salts

    Take a cup of very hot water and desolve the epsom salts,take rest of ingredients and place in a clean 2 liter bottle and let work out. Add epsom solution. Add water to fill to 48ozs(3/4 full).Shake well.

    TO USE: Cover soil/medium with plastic,with lights off mist plant all over,especialy under leaves,
    Wait 20 mins,then spritz off with clean fresh water shaking as much water off plant as you can.
    The fresh water spritz rinse will remove the solution along with the desolved remains of the mites and their eggs.

    Have fun with your new "Mite Eradicator"

    Note by MrFixit: Water plants 1/2 hour before spraying. This will help keep your plants from absorbing the spray.

    This solution has been tested and used as directed will not burn plants,the rinse is very important though as it removes the spent solution before it can concentrate and burn the plant. It also removes most of the dead mites and eggs so you don't end up smoking them.

    The formula can be diluted further,to 1 liter and it will still kill the mites but isn't as effective at dissolving and removing the mite parts.
    Since removing the mite debris is desirable,I recommend the stronger solution,just remember to rinse and shake.
    This formula is alkaline(about 7.8-8) so please remember to rinse.

    Mite irradication is absolutely assured and guaranteed if used as directed.
    I've never seen ANYTHING work this well for mite irradication!!
    I used to gas my booths for mites,it worked but they came back,I haven't seen a living mite in a long time now.They haven't come back,partly because of cooler weather,partly because I hosed the Roses that were infecting everything with the formula and wiped out all the mites during testing.
    The only thing I wish I'd done different is,I wish I would have done sections of the Roses and preserved
    some of the mites for later tests.I've had to go searching for victims to test it on and there just aren't any left!! I did find some victims for my final tests in the park where we have meetings,the plants by the river are pretty sickly and infested(were I should say,I walked around with ONE pint bottle and cleaned up most of the area.LOL)
    If news of this formula were to become widespread,mites would become an endangered species!!!So GOOD HUNTING !

    "PM'd BankRobber and he told me to post this:
    I have been experimenting with similar formulas, so far 2 work.
    Trial #1: 1/2 cup baking soda , 1 cup vinegar , 1/2 cup apple juice. Dilute to 2 liters.

    Trial #2 1/2 cup baking soda , 1 cup vinegar , 3 tablespoons lemon juice , 2 drops dish soap .
    Dilute to 40 fluid oz's.

    I've tried this on: Wandering Jew,Spider Plant,Fushias,Gladiolis,Roses,Sweet Elysium,Clovers,Daisy,
    Rhodadendron, Lawn(grass)
    So far it works,both formulas. #2 works best outside and best overall
    It has killed any small insects I've tried it on except FLEAS(Darn it!)
    So far its killed mites,thrips(Adult),aphids,clover mites, whatever mite type insects that were all over the Gladiolis and it sickened and effected Grass Gnats and mosquitoes.(the mist knocked them down,couldn't find them in the grass to watch if they died but they were having difficulty flying)
    I'm waiting for long term effects on the plants I've sprayed,before I'll try it on my plants.
    Try mixing up some and try it outside on whatever you can find with an infestation.
    The original recipe from a Landscape gardener was: 1/2 cup baking soda, 1 cup vinegar,2cups apple peels.
    Blend/Puree , filter , dilute to 2 liters. I haven't tried this one yet (no apple peels).
    The trick seems to be 1/2 cup Baking soda to 1 cup vinegar,diluted to approximately 2 liters.
    The dishsoap helps wetting & the juices boost effect. #2 seems to help with molds/fungus also.It reduced blackspot on Roses,Gladiolis and Rhodi's and white mold on Roses.( The coast is a perfect proving ground for this stuff!!! We have ALL the bugs and molds !!! I don't have to go far to find infestations of all kinds.)

    For 2 days I have hosed my backyard with this stuff,so far it has reduced blackspot & powdery mildew(white mold),killed all the small insects(size seems to matter on kill,gnats or smaller).
    The only plants adversely affected so far are FERNS (they don't like it much,wilted some).
    The fleas seem unaffected as are the garden spiders,wood lice,beetles and other large hard insects.
    I'm using it far more than necessary to see if it hurts the plants. Repeating doses even after the bugs are dead. The gladiolis were REALY bad with blackspot mold and some kind of black sucker insects about the size of a pinhead.The Glads are doing fine both mold and insects gone! The wandering jew and spider plants are actualy perking up from it.The clover mites? WIPED OUT! Rose mites? WIPED OUT! Grass gnats and mosquitoes? VASTLY REDUCED! Scale insects? DEAD! Aphids?DEAD!
    [THE GARDEN??? (smells like a "Caeser Salad" ! ) ALIVE.]
    Seasider "

    There seems to be some mild burning where the solution was left on and collected/concentrated.
    I would recommend using the 2 liter dilution and spritzing with fresh water afterward and shaking off as much as possible so the formula doesn't collect and concentrate itself to the point it burns tender leaves.
    I didn't notice any damage except where it had concentrated and dried,so spritzing and shaking off should do the trick.As far as effectiveness goes,wow! The death and destruction it deals to mites is impressive !!
    Popping browning eggs melting,imploding adults,body parts and debris slowly dissolving......

    The BORG rule ,of mite terror, is OVER !!!!

    WARNING !!
    A member had severe burning that he attributes to residues drawn out of the container by the vinegar.
    USE A CLEAN CONTAINER !! Do not use realy strong vinegar or any with SULFITES in it.


    Continue fighting the good fight.. hope this helps everyone

    what is safer soap where can i get it is that the name also have 250 watt mh hps how many plants can i grow under it new at this thanks 4 the help

    FLoJo Well-Known Member

    safer soap is an insecticidal soap that you can get at some home improvement stores and most nurseries and hydroponic stores.

    as for your second question it depends...style of growing, veg time, etc.. use search or go to grow journals and see what other peeps are doing

    Have you ever used Tanglefoot? I heard that you should smear it around the container brim, but I've heard it's okay to put on the main stem near the soil. Is this true?

    lehua96734 Well-Known Member

    i am having a mite problem also. i checked out differant forums and kinda made up my own mix using lemonsoap, lemon juice, cayanne pepper, tobacco juice and hot sauce. let it sit over nite, filtered it and sprayed it on my plant. heres hoping it works.

    giantart Well-Known Member

    What i have found works best is to buy a pack of American spirit cigarettes (No additives) and remove all of the tobacco, add to a quart of water and simmer for about a half an hour. Then add 1/2 quart of water (Phed of course) and spray under and all over leaves and plant. (Store leftover liquid in fridge)

    Tried Neem Oil for weeks with almost no affect but this solution killed them the first time!! Voila~ it was like a miracle. see what others think but thats what worked for me and i had them bad!!

    Commercial greenhousemen are very familiar with nicotine based insecticides. They are also natural and organic.

    Good luck!

    Seamaiden Well-Known Member

    You will get more if you just use the AS loose tobacco. :)

    FLoJo Well-Known Member

    Ya i went the american spirits route but like seamaiden said if you go to your local smoke shop you can get loose tobacco that is of better quality and cheaper for the amount you get. yes it is all organic and you can add to it whatever you want but be aware that two spotted mites build up resistance to whatever you throw at em so be sure to do treatments every couple days till you dont see them and then a couple more times after that lol... i would have to burn down the building that had mites in it that were immune to nicotine!

    flo how long do you do the #2 treatment and how often

    anotherchance New Member

    if you can keep your temps under control you can be done your grow before they get a chance to gain significant numbers. and if you do that then the predators will work well

    cyrberus Active Member

    that number 2 mixture that flojo has up is killing my plant so dont use it and does anyone know how i can fix my plant ?

    cyrberus Active Member
