Pests 101 — Meet the Culprits

First, let's meet the common troublemakers:

1. Spider Mites

  • Signs: Tiny webbing (especially under leaves), speckled yellow or brown spots on foliage.

  • Habits: Love hot, dry conditions. Nearly invisible to the naked eye — they look like moving dust.

2. Mealybugs

  • Signs: White, cottony clumps on stems, leaves, or at leaf joints. Sticky residue (honeydew) on surfaces.

  • Habits: Hide in crevices and multiply fast.

3. Fungus Gnats

  • Signs: Little black flies hovering around the soil; yellowing leaves.

  • Habits: Larvae feed on roots, adults lay eggs in damp soil.

4. Aphids

  • Signs: Clusters of tiny, soft-bodied insects (green, black, or white) on new growth; sticky leaves.

  • Habits: Suck plant sap, causing deformed growth.

Pro Tip: Early detection is everything. Pest outbreaks can often be avoided if you catch them before they become an army!

Play Detective — How to Spot Problems Early

Inspect Regularly Check your plants weekly. Look under leaves, along stems, at soil level, and even on pots. The sooner you spot changes, the better.

Know the Clues

  • Sticky Leaves: Often caused by honeydew from mealybugs or aphids.

  • Webbing: Always investigate for spider mites.

  • Yellowing Leaves: Could be pests — or overwatering, so double-check.

  • Slow Growth or Misshapen Leaves: Might mean insects are sucking out vital nutrients.

Magnify Your Investigation A $5 magnifying glass can be your best tool. Some pests are tiny and almost impossible to spot without help.

Quarantine New Plants Always isolate new plants for two weeks to spot hidden pest hitchhikers before introducing them to your collection.
