There were spider mites on a few plants. And I happened to get a hold of some dry ice (frozen carbon dioxide). So, I put each mite infected plant in a plastic bag, with a piece of dry ice large enough to displace trapped air volume in the bag after sublimation. The bag was tied loosely so that evaporated dry ice could purge air out from it. I left the plant in the bag for 4 hours. Not sure the mites were killed.
12 hours after getting the plants out, I see some leaves discolored, turning white or slight brown. I don't think the injury is severe. The plants should survive. Sphagnum seems unaffected though.
Has anyone tried this method to eradicate pests? Was it effective?
