Lessons Learned by Spider Mites / Discussion

Hello Everyone,

This season I had an absolutely awful time with spider
mites. I’m somewhat experienced with
pepper plants but this one almost beat me.
I’ll be direct and to the point.

  • Late last season, I saw some crinkled leaves. I couldn’t figure out if it was a bug or because of the 110 degree heat.
  • Everyone once in a while, I would see a little spec that
    almost looked like a tiny drop of water.
  • I now know that what I was seeing was an adult spider mite—not
    an egg.
  • I have about 27 plants.
    I overwintered them. During the
    winter, the
    mites continued to spread.
  • It’s looking like I might have a 96% success rate with my
    overwintering (1 of 27 dead).
  • I put my plants back outside. My plants are no longer growing normal
    leaves. All the leaves are starting to
    look gnarled like this:
  • I buy a magnifying glass and finally confirm it is spider
    mites. These mites are roughly 1/32 of
    an inch in size. Without a magnifying glass
    and with my decent eyes, I can only spot the largest adults as a white spec.
  • These spider mites prefer new growth. They'll attack a leaf when it's 1 mm in size.
  • As usual, I put a systemic on all of my plants. Screw being organic. I also confirm that food-grade systemics DO
    NOT kill spider mites.
  • The spider mites are still there. I buy an oil based organic concentrate
    spray. It turns out that one of the ingredients in my spray is fish oil. It makes
    my plants smell like fish ass.
  • I follow the directions and spray the hell out of all my plants. Still mites.
    I spray the hell out of my plants again.
    Still mites. I spray the hell out
    of them about two times more.
  • The leaves on my plants start dropping off from being sprayed over and over.
  • Desperate, I cut the leaves off of every single plant I own. I then spray the hell out of my branches and
    stems.
  • I start finding tiny spider webs on my
    plants. I remove the web and new ones
    return. The mites are still there.
  • Desperate, I trashed the worthless fish ass organic spray
    and switched to a non-organic sulfur spray.
    In the past, my leaves were mostly able to handle this spray once or twice, but a
    couple varieties burned very quickly with the sulfur. Screw it.
  • I spray the hell out of my plants. Suddenly the mites start disappearing. I’m still finding webs. When I do, I spray the hell out of the plant and remove the web.
  • The webs are becoming less and less. I'm probably damaging some tiny leaves but I don't care.
  • The spider mites are almost gone. For the first time this season I’m starting
    to grow leaves that aren’t gnarled.

I know that spider mites blow in the wind so they may always come back, but at least now they are nearly under control

I hope people learn from this experience. But I’m also interested if anyone has any
additional ideas or ability to contribute.
Clearly my biggest mistake was not identifying the source of the problem
first thing.
