mealybugs on Echinocereus Pentalophus
Quick answer
If your Echinocereus Pentalophus has mealybugs, the most likely cause is: Mealy bugs are the most common pest of cacti and succulent collections, including Echinocereus pentalophus; they are small, elliptical insects covered in a waxy white meal that settle on the stems between the hemispherical clusters, hide in the crown, and colonise the roots, where the related root mealy bug shows up as a white, dusty substance on the inside of the pot and around the root system.
Start here:
- 1. Bare the roots of the affected E. pentalophus, wash every trace of old soil off the root ball, then dip the whole plant in a dilute pesticide or insecticidal soap solution before repotting into fresh, fast-draining cactus mix.
- 2. Dislodge visible mealy tufts from the crown and between the clustered stems with a stiff spray of water, then treat with insecticidal soap and repeat applications to catch newly hatched crawlers before they spread to neighbouring cacti.
