Short answer
Your Golden Pothos has a spider mite infestation, which is common in dry indoor environments and causes stippled leaves and fine webbing. The most effective fix is to physically wash the leaves, treat them with neem oil or insecticidal soap, and increase local humidity to prevent future outbreaks.
Seeing fine webbing and tiny yellow or white speckles on your Epipremnum aureum is a classic sign of spider mites. While these pests are a nuisance, they are manageable if you act quickly, especially since Pothos are hardy plants that can handle the initial stress of treatment.
Spider mites thrive in the dry, stagnant air often found in homes during the winter or near heating vents. They feed on plant juices by piercing cells, which results in the characteristic pale stippling seen on the upper surface of Pothos foliage.
Check: Check the undersides of the leaves near the stem attachment for tiny, slow-moving translucent dots or fine silk webbing.
Fix: Isolate the plant, shower the foliage thoroughly with lukewarm water, and apply insecticidal soap or neem oil to the undersides of the leaves every 5-7 days for at least three weeks.
While Epipremnum aureum is adaptable, extremely low ambient humidity weakens the plant's natural defenses, making it much more susceptible to spider mite colonization. Persistent dry air can also cause the foliage to lose its luster and become brittle.
Check: Check if your Pothos is placed directly in front of a heating vent or if your home's relative humidity is consistently below 30%.
Fix: Move the plant away from heat sources and consider placing it on a pebble tray or grouping it with other plants to naturally raise the humidity in its immediate vicinity.
Excessive dust buildup can sometimes be mistaken for webbing or surface spots, and it can harbor pests by obstructing leaf pores. If the speckling is uneven and wipes away with a damp cloth, it may be a combination of dust and minor pest activity.
Check: Gently wipe a leaf with a damp, white paper towel; if the 'speckling' transfers to the towel without moving, it is likely just dust.
Fix: Wipe the leaves monthly with a damp cloth to keep the stomata clear and the plant clean.
When to worry
You should take immediate action as soon as you see webbing, as mites multiply rapidly and can cause the entire vine to collapse or drop all its leaves within a few weeks.

Diagnose my Golden PothosYou can remove heavily damaged leaves, but it will not solve the infestation because the mites are likely present on seemingly healthy leaves as well. You must treat the entire plant.
No, repotting is unnecessary and can cause extra stress; spider mites primarily live on the foliage, not the soil, so changing the dirt will not remove the pest.
Unfortunately, the white stippling caused by spider mite feeding is permanent damage to the leaf tissue, though the plant will produce new, healthy growth once the infestation is cleared.
