    I read about this somewhere. Tried it in desperation, as the mite infestation I thought I had gotten rid of was killing my 6 week flowering buds. I used a mister bottle, and was very careful to unplug everything in there so I had no ignition source. I sprayed the plants enough to get them wet, top and bottom, and to my surprise, I could find no living mites afterwards, and very few of the eggs hatched out either.

    I followed up every fourth day for three treatments, and the mites appeared to be totally gone, with no harm whatsoever to my crystally later stage buds.

    The alcohol evaporates quickly with no trace, and the misting with alcohol appeared to have no effect on the glandular trichomes, even under magnification. It also seems to have totally cleared my clone closet of mites without my having any harmful residue on them.

    Once again, take care with all ignition sources.

    So the rubbing alcohol doesn't hurt the plants at all and doesn't melt the keef off the buds?

    Lady G, greetings from a tree in the southern portion of the Emerald Triangle, I agree I wouldn't use iso for pest control on living plants. We use garlic tea, then flush plants before harvest. But actually never had a prob with mites till we brought them home on clones from the dispensery.

    I use a tea also to make tea by brewing a quart of boiling water and a tablesoon each of ground raw garlic, ground raw oinon, mixed Italian seasoning, ground cinnamon and ground cloves. Mix the tea with a tbls cornstarch and dish soap and add 8 ounces of denatured alcohol. It makes a powerful general pesticide.
    The credit for this tea belongs to Ed Rosenthal.

    PS The denatured alcohol can be found at any hardware store.

    So you're saying you would dip or spray this on buds in the later stages of flowering? I would think there would be no way you could not taste and smell that on the end product. The iso leaves absolutely no residue and like I said, my buds are very heavily trichomed, and I examined them after the alcohol had evaporated, and the crystals were no different than before looking at them under a 30 power lighted scope.

    I tend to get mites from time to time as they seem to love the composted chicken manure I use, and short of straight up poison this is by far the best solution I had found. I know Ihave a helluva time getting totally rid if them, and this seems to have gotten me there for the first time in quite a while.

    Dude, just buy some neem oil and you're all set. Ten bucks at the most, why risk messing up your plants...

    ive heard that putting corn shocks on the stalks of the plants can repel pests. Anyone able to support or debunk that?
