Houseplant Pest Control — Identification and Treatment

Pests happen to every plant parent. The key is catching them early and acting fast.

🔍 Most Common Houseplant Pests

Spider Mites

Signs: Tiny dots on leaves, fine webbing underneath, yellow stippling.

Treatment: Spray with neem oil solution (1 tsp neem + 1 tsp dish soap per liter of water). Repeat every 3 days for 2 weeks.

Fungus Gnats

Signs: Small black flies hovering around soil.

Treatment: Let soil dry out completely between waterings. Use yellow sticky traps. Add a layer of sand on top of soil.

Mealybugs

Signs: White cottony clusters in leaf joints and undersides.

Treatment: Dab with cotton swab soaked in rubbing alcohol. For large infestations, spray with insecticidal soap.

Scale

Signs: Brown or tan bumps on stems and leaves that don’t scrape off easily.

Treatment: Scrape off manually. Apply neem oil weekly for 3 weeks.

Aphids

Signs: Tiny green, black, or white insects clustered on new growth.

Treatment: Blast with water. Spray with insecticidal soap. Repeat weekly.

🛡️ Prevention Tips

  • Quarantine new plants for 2 weeks before placing near others
  • Inspect plants weekly (make it part of your routine)
  • Don’t overwater — fungus gnats love wet soil
  • Keep leaves clean — wipe with damp cloth monthly
  • Good air circulation discourages pests
