Pests happen to everyone — it’s just part of growing plants. The difference is catching them early and handling them naturally, without nuking your plant (or your home) with harsh chemicals.
How to Identify Pests
Make it a habit to inspect your plants — especially the undersides of leaves and where leaves meet the stem, which is where trouble hides. Here are the usual suspects:
- Spider mites — tiny specks, often with fine webbing between leaves and stems. Leaves get pale, stippled or dusty-looking. They love hot, dry air.
- Mealybugs — little white, cottony/fuzzy blobs tucked in leaf joints and along stems.
- Aphids — small green, black or white soft-bodied bugs clustered on new growth and buds. They leave sticky "honeydew" behind.
- Fungus gnats — tiny black flies buzzing around the soil. The adults are just annoying; the larvae in the soil are the real issue. A sign of soil kept too wet.
- Scale — small brown, waxy, immobile bumps along stems and leaf veins that scrape off with a fingernail.
- Thrips — slender, fast-moving specks; leave silvery streaks and black dots on leaves.
General warning signs: sticky residue, yellowing or speckled leaves, distorted new growth, or fine webbing. Catch it early and treatment is easy — an infestation left for weeks is a much bigger battle.
How to Treat Pests — Herbal Plant Soap & Diatomaceous Earth
Two natural tools handle the vast majority of common pests:
Herbal Plant Soap (for the bugs on the plant)
Insecticidal soaps work by breaking down the protective outer coating of soft-bodied pests — aphids, mealybugs, spider mites, thrips — on contact.
- Spray thoroughly, coating both sides of the leaves, stems, and every nook where pests hide. It only works where it actually lands, so be thorough.
- Repeat every 3**–5 days** for a few applications to catch newly hatched eggs the first spray missed.
- Test on a small area first with sensitive plants, and avoid spraying in hot direct sun.
Diatomaceous Earth (DE) (for crawling pests & the soil)
DE is a fine powder made from fossilized algae. It's non-toxic — and food grade: the microscopic razor-sharp particles scratch through a bug's waxy exoskeleton, and it dries them out. Brilliant for fungus gnats, and crawling pests.
- Sprinkle a thin layer on the soil surface to wreck the life cycle of fungus gnats, or dust it on affected areas.
