Debugging Houseplants Before Bringing Them Indoors

Advice for removing pests from houseplants that spent summer outdoors.

Step-by-Step Process

1. Strong hose spray: Blast leaves, stems, and undersides to dislodge insects.
2. Remove top debris: Scrape off loose soil and surface litter where pests hide.
3. Soil drench (if soil pests suspected): Submerge pot in water up to rim for 1–2 hours. Pests flee flooded soil for air.
4. Inspect and quarantine: Keep separate from other plants for 2–4 weeks.

Realistic Expectations

Most outdoor insects die off naturally indoors within weeks due to low humidity and lack of hosts. No single treatment covers all regional pests.
