Never say never... I've NEVER had spider mites. EVER. Two years ago decided to try growing Catasetum. All of a sudden this year, a spider mite infestation on all five. Having a party, live band, lots of snacks and beverages.
And having never experienced them before, it took me quite a while to figure out why the leaves were looking so funny. Duh.
Catasetum being a spider mite magnet... it's my new reality. UGH.
