Spots, webbing or bugs
Spots, webbing, or bugs on my Flaming Katy?Kalanchoe blossfeldiana
If something is visibly living on your Flaming Katy — or its leaves have suspicious spots — catching it early is everything. Here's how to identify the usual suspects and treat them.
Spider mites. Wipe the leaves down (avoid soaking the crown), raise humidity nearby without wetting the leaves, and treat with insecticidal soap or neem oil weekly until clear. Isolate it from other plants.

What's causing it
Spider mites
How to tell: Fine webbing in the leaf joints, tiny moving dots, and a stippled, dusty look to the leaves. They thrive in the dry air many homes have.
The fix: Wipe the leaves down (avoid soaking the crown), raise humidity nearby without wetting the leaves, and treat with insecticidal soap or neem oil weekly until clear. Isolate it from other plants.
Mealybugs
How to tell: White, cottony fluff tucked into leaf joints and along stems, sometimes with sticky residue.
The fix: Dab each one with a cotton bud dipped in rubbing alcohol, then treat with neem oil. Check weekly — they hide.
Scale
How to tell: Small, brown, limpet-like bumps stuck to stems and the undersides of leaves, often with sticky honeydew.
The fix: Scrape them off gently with a fingernail or old toothbrush, then treat with neem oil and keep checking.
Fungal leaf spot
How to tell: Brown or black spots, often with a yellow halo, usually after the leaves were wet or the soil was overwatered.
The fix: Remove affected leaves, improve airflow, avoid getting water on the foliage, and let the soil dry more between waterings.
Sunburn (not a pest)
How to tell: Dry, bleached, or brown dry patches only where strong direct sun hits the leaf, with no bugs or webbing — Flaming Katy is bright / direct light.
The fix: Move it back from the glass into its bright / direct light range.

Common questions
How do I get rid of bugs on my Flaming Katy naturally?
For most houseplant pests: isolate the plant, rinse it off, wipe the leaves, and treat with insecticidal soap or neem oil once a week until they're gone. Dab mealybugs with rubbing alcohol. Persistence beats strength.
Are pest treatments safe around pets?
Neem oil and pesticides can irritate or harm curious pets — keep treated plants out of reach while they dry, follow the label, and check with your vet or ASPCA if a pet ingests any.
