Preventing Root Aphids in Houseplants

Question about root aphid origins. Expert clarifies root aphids are not typical in standard houseplants.

Key Points

• Root aphids occur in plants grown under lights (e.g., cannabis), not typical houseplants.
• Houseplants use sterile, soilless mixes – no soil-borne pests.
• Using garden soil or compost introduces pests.

Prevention

1. Use only sterile peat or coir-based potting mixes.
2. Keep top quarter of soil very dry – larvae need constant moisture.
3. Never use outdoor soil for indoor pots.

If growing under lights for specific crops, consult specialized forums.
