    I'm 100% sure Ive got a spider mite infestation and I'd like some help on how to kill them.

    I've heard that soapy water will do the trick, but I'm concerned that the soap will bring the soil's pH up to a dangerously basic level (maybe), so would you use lemon juice or vinegar to level the pH out?

    I've heard the soapy water trick from two different people, and neither said anything about adding lemon juice/vinegar, and you can always lower the pH later (acidify it), so I think I'll go ahead and do this...?

    Any suggestions? Comments? Feedback?

    Floramite:mrgreen: its the best and will stay in the plant for up to 45 days. I had a bad infestation and this is the best stuff. I think its 30 bucks or so. But by all means get it

    Thanks, but I could only find it for $250 (I've only looked a bit online, haven't gone to a shop yet) and I'm trying to keep as many chemicals away from my plant as possible...

    i'm using all household items for nutrients (selective compost ingredients) and I'd like to do the same to keep the mites at bay.

    I haven't brought any soapy water out there yet (it's raining now), but last time I checked on my little one (m/f hasn't shown yet) his upper leaves were yellowing a bit more, so either he needs water, N, or the mites are taking hold :cry:

    FYI:
    Soap pH
    Camay 9.5
    Dial 9.5
    Dove 7.0
    Irish Spring 9.5
    Ivory 9.5
    Lever 2000 9.0
    Palmolive 10.0
    Zest 10.0

    Lemon juice 1.8~2.3
    Vinegar 2.4~3.4

    I needed to find this information, and thought maybe you all could use it to make your own mite sprays, so hopefully someone can benefit from this.

    I'll let you know how this works out, since I still need to figure out what concentrations of each I need to achieve the ideal pH of 6-7.

    Pyrethrum - Wikipedia, the free encyclopedia

    I use a pyrethrum based product called "Eight" . . . can be used up to one day before harvesting.
    I wouldn't spray it on my buds, unless they were just starting.
    For mites, no matter what you use, you'll likely want to spray twice . . . once to kill off the adults, again in 2-3 weeks to kill any hatchlings.

    well, it looks like something i did has helped..i don't know what it was, but the number of spots has decreased...maybe the rains drowned them all(?), because I havent sprayed them with soapy water.

    two of the largest leaves are showing some yellowing along the edges, so i went out today and added some cuttings (scallions, broccoli, spinach), coffee grounds, eggshells, and a banana peel.

    My vote goes with BlackLight and the Triazicide and a sprayer ~20/25 for both...

    Why are you so sure you have mites? I don't see anything in the pictures to indicate mites. Do you see any webs? Sure way to tell is magnification on underside of leaf.
    they're easy to see and look like crabs.

    The mites have been gone for a little over a month...I don't know exactly what I did, but it worked?

    I was almost positive that it was a mite infestation after I read somewhere that they create webs between the roots, strangling them, cutting off circulation, resulting in white spots forming on the leaves. I don't know if it's true, but having had very little prior experience, I found it to be the best explanation. I also read that they are so small that they oftentimes need a magnifying lens to be spotted, and I couldn't find my lens so I didn't check.

    I now have a caterpillar problem though, and I forgot to even look for BT at Wal*Mart yesterday :cry:

    Ok its harvest time. I have been putting up with a slight mite problem. So far I have been keeping them under control and after this harvest im going to bug bomb the whole place and do it once and for all.

    Let this be a lesson to me and everyone else. If someone gives you a clone check it carfuly. I did not and have been paying for it..

    So my question is. I dont want to spray or do anything to my drying buds that would be bad for me.. Will these little buggers die if i put them in a deep freeze? like -5.. or will they just go dormant and hatch when it warms up? I have put wet buds in the freeze and they come out just fine.

    these webs on my prize buds suck!!

    HELP PLEASE!!
