Features
- Named 'scale' because their hard, waxy covering resembles fish scales or tiny shields protecting their soft bodies underneath
- Appear as small, stationary bumps (1-5 mm) on stems and leaf undersides. Can be armored (hard) or soft. Colors range from white and yellow to brown and black
- Pierce plant tissue with needle-like mouthparts to suck sap. Adults remain permanently attached to one spot on the plant
- Causes yellowing, leaf drop, and stunted growth. Soft scales produce honeydew, which leads to black sooty mold and attracts ants
- Young 'crawlers' are the mobile stage that moves to new spots. Once they settle, they build their protective scale and remain fixed
- Adults measure 1-5 mm long depending on species. Crawlers are tiny and barely visible without a magnifying lens
- Active year-round in warm climates or indoors. Crawlers are most active in late spring and early summer
- Attack a wide variety of indoor and outdoor plants, including citrus, roses, ferns, ficus, and many fruit and shade trees
- Inspect new plants thoroughly. Prune and destroy heavily infested branches. Encourage natural predators like ladybugs and parasitic wasps
- Scrape off small infestations with a fingernail or toothbrush. Apply horticultural oil or neem oil during the crawler stage for best results
