spider mites on Mammillaria Baumii
Quick answer
If your Mammillaria Baumii has spider mites, the most likely cause is: Eight-legged spider-mite arthropods are so small that their damage generally shows up before the pests themselves, with the most common variety red and only a fraction of a millimetre across; they form fine, dense webbing over cactus stems and destroy the epidermis as they feed, leaving an infested Mammillaria lighter in colour or eventually silvery-yellow with extensive scarring on the youngest growth.
Start here:
- 1. Inspect neighbouring cacti upwind and downwind from an infested Mammillaria to locate the source and any new colonies, since mites drift into a collection on a breeze of silk.
- 2. Apply a miticide following the label directions closely and plan on multiple treatments, since one application is virtually never 100 per cent effective against either the mites or their eggs.
