Spider Mites on Pothos — Spotting Them Before the Damage Gets Severe
Pothos (Epipremnum aureum)
Symptoms
- stippled leaves
- fine webbing
- dusty-looking leaves
- tiny moving dots
- spider mites
Causes
Low humidity and dry conditions
Tetranychus urticae thrives in exactly the conditions that pothos is often kept in — warm, dry indoor air with low humidity. Unlike mealybugs which spread via direct contact, spider mites can drift on air currents, making them challenging to control once established. Their reproductive rate at 70-80°F in low humidity is extremely fast: egg to egg-laying adult in as little as five days.
Introduction from other plants
Spider mites on pothos are often introduced on infested new plants placed nearby. The fine webbing from spider mites can literally bridge between neighboring plants.
How to Fix It
- 1
Confirm by the white paper test: shake a pothos leaf over white paper. Moving dots smaller than a pinhead are mites. A hand lens makes this much easier. On pothos, the damage shows as a dull, bronzy stippling across the leaf surface.
- 2
Take the plant to a shower and spray both sides of all leaves with a strong stream of water. This physically removes and kills large numbers of mites and destroys their webbing.
- 3
Follow up immediately with neem oil spray applied to every surface, working it into the leaf axils along the vine where new growth emerges — that's where a pothos infestation regroups fastest. A miticide containing abamectin is an alternative for resistant populations. Space repeat applications about a week apart, and don't stop at just one or two rounds.
- 4
Nudge the ambient humidity up around the plant. Pothos tolerates average home humidity just fine, but mites don't — above roughly 60% relative humidity their reproduction rate drops off sharply, so this step does a lot of the long-term prevention work on its own.
Prevention
- Keep humidity above 40–50% to make your home inhospitable to spider mites
- Run a damp cloth down each vine's leaves once a month — the wiping catches any eggs or fresh colonies before they spread to the next leaf
- Quarantine new plants for two to three weeks before introducing them to your collection
