Spider Mites: How to Identify and Eliminate Them for Good
Spider mites are tiny but devastating. An infestation can defoliate a plant in weeks. Here's how to identify, treat, and prevent them.
Spider mites are not insects — they're arachnids, related to spiders. They're barely visible to the naked eye but multiply rapidly, particularly in hot, dry conditions.
Identifying Spider Mites
Look for:
Run a piece of white paper under the leaves and tap. If tiny dots move — you have spider mites.
Why They Thrive
Spider mites love hot, dry conditions — exactly what happens to plants near radiators in winter. Low humidity is the primary driver of infestations.
Treatment Plan
Step 1 — Isolation. Move the affected plant away from others immediately.
Step 2 — Shower the plant. Take it to a shower or sink and spray all leaf surfaces (top and bottom) forcefully with water. This knocks mites off physically.
Step 3 — Apply treatment. Options:
Step 4 — Repeat. Spider mite eggs hatch over 5–7 days. Repeat treatment every 5 days for at least 3–4 weeks to break the cycle.
Prevention
Raise humidity around susceptible plants. Inspect leaf undersides weekly. Keep plants healthy.
