I'd like tot think of myself as a rather experience grower, I can usually solve all of my problems through trial and error, but I have one problem I can't seem to solve.
I have thrips that seem to be resistant to a few different insecticides. I've double dosed Monterey as well as Captain Jacks to name a couple. Spraying every other day for a week at a time, but they just won't die.
I believe the cause is they are just genetically resistant, probably came from somewhere where insecticides are used a lot (a dispensary, a friend's grow, etc...)....
I'm wondering if anyone can confirm this for me, and is my only option to go nuclear?
Plants are vegging, temp stays about 75 degrees, they are in straight Oceanforest right now.
To be clear, I've collected a few, doused them directly with diluted Monterey and they didn't die.
PS. If you guys need me to fill out the form to give me an answer for this, than I definitely came to the wrong place.
They aren't unkillable, you just are using the wrong method. Get some predatory nematodes and some Stratio-S (formerly Hypoaspis Miles). Beneficial Insectary in Redding CA is a good source. End of problem, no more nasty pesticides.
