pests on Croton
Quick answer
If your Croton has pests, the most likely cause is: Crotons are susceptible to sap-feeding pests including spider mites, mealybugs, scale, and thrips. Spider mites thrive in hot, dry conditions (<40% humidity) and cause stippling, webbing, and leaf drop. Mealybugs appear as white cottony masses on stems and leaf joints. Pests extract sap, weaken plant vigor, and transmit pathogens. Low humidity and poor air circulation accelerate infestations.
Start here:
- 1. Isolate affected croton immediately to prevent pest spread to nearby plants
- 2. For spider mites: Shower plant thoroughly (especially leaf undersides), apply neem oil or insecticidal soap every 5-7 days for 3-4 weeks
