spider mites on Echinopsis
Quick answer
If your Echinopsis has spider mites, the most likely cause is: Spider mites are tiny pests that appear as colonies of crawling red-colored specks and produce visible webbing, often gathering in the protected microhabitats between the spines and areoles of cacti like Echinopsis. Like many sap-sucking pests, they have a waxy coating that keeps moisture in their bodies and allows them to survive dry indoor conditions until populations build up enough to deform or discolor the stem.
Start here:
- 1. Look closely between the ribs and around areoles for fine webs or red specks, since colonies hide in the same crevices that protect areolar fuzz on cacti and are easy to miss until damage is visible
- 2. Spray the entire cactus with a mild dish soap and water solution until the plant is dripping wet to dehydrate and kill the mites on contact, because damaging their waxy coating is what kills them
