Two spot spider mites keep coming back! My Calathea white fusion keeps getting small infestations of mites. Nothing seems to work to get rid of them except beneficial insects (predatory spider mites), but they’re pricey. My Calathea reacts badly to neem, soap, and alcohol spray, so I can’t use that. Humidity in the room is good enough for my orchids, so I assume it’s OK for my Calathea. But the mites still return. Has anyone tried Arber bio insecticide and does it work? What about systemic insecticides that spider mites are not immune to? Any advice is appreciated.
