A bad infestation will have them spinning webs all over your buds. It is almost impossible to remove that silk.
I fought spider mites before and they are relentless little pests.
You are pretty close and it may be better to chop and wash asap.
Spider mites are like terminators, they absolutely can’t be stopped. If you have them, cut your losses, and bug bomb your house. Chances are that will only piss them off, but worth a try.
I bug bomb the basement every so often with a product that is safe to use around a pilot light and scrub every tent after harvest.
The organishield product wiped the mites and fungus gnats out fast and they have not returned.
A preventive I use are mosquito bits soaked in warm water overnight and strained out. To this concoction I add a teaspoon of rosemary oil. I read that plants uptake a compound called rosemaric (sp?) acid that the chomping insects don’t like.
No one has complained about a rosemary flavor in what I grew last year.
