Spider Mites on Mint
Commonly affects: Mentha spicata, Mentha piperita (Mint)
Fine yellow or white stippling appears across leaf surfaces, with fine webbing visible between leaves and stems in more advanced infestations. Affected leaves can eventually dry out and drop.
Potential Causes
- 1Hot, dry indoor conditions, particularly for container-grown mint kept indoors over winter
- 2Low humidity around the plant reducing mites' natural predators
- 3Dusty leaves providing a more hospitable surface for mites to establish
Solution Steps
- 1Rinse the plant thoroughly under running water to physically dislodge mites and eggs.
- 2Apply insecticidal soap or neem oil to all leaf surfaces, repeating every 5�7 days for two to three cycles.
- 3Increase humidity around the plant, since mites struggle to reproduce above 60% relative humidity.
- 4Isolate the affected plant from other houseplants until the infestation is cleared.
Prevention Tip
Keep indoor mint in a spot with good humidity and rinse the foliage occasionally, since spider mites specifically favour hot, dry, dusty indoor air.
