Short answer
Fine webbing and speckled leaves on English Ivy are classic signs of a spider mite infestation, which thrives in the dry indoor air common in many homes. The most effective fix is to physically wash the leaves and apply a neem oil treatment over several weeks while increasing the local humidity.
English Ivy (Hedera helix) is notoriously susceptible to spider mites, particularly when kept in environments with low humidity or poor airflow. While these pests are a major nuisance, they can be managed with consistent treatment, provided you catch them before the foliage becomes severely damaged.
These microscopic pests puncture the leaf cells to feed, causing the characteristic light-colored speckling or 'stippling' on the foliage. They spin fine, silky webbing between stems and along the undersides of leaves as they move across the plant.
Check: Hold a piece of white paper under a leaf and tap the stem; if tiny specks fall onto the paper and move, you have mites.
Fix: Isolate the plant, shower it thoroughly with lukewarm water to dislodge the pests, and treat with insecticidal soap or neem oil every 5-7 days for at least three weeks.
English Ivy prefers higher humidity levels than most average homes provide. When air is excessively dry, the plant's natural defenses weaken, making it significantly more attractive to mite colonies.
Check: Check if leaf tips are also turning brown and crispy alongside the speckled pattern.
Fix: Use a humidifier or place the plant on a pebble tray filled with water, ensuring the pot sits above the water line to increase moisture levels.
Placing Hedera helix near heating vents or in warm, stagnant air accelerates its water loss and mimics the dry, hot conditions that spider mites thrive in. This stress causes the foliage to lose vigor and become more prone to pests.
Check: Place a thermometer near the plant to ensure temperatures do not frequently exceed 75°F (24°C).
Fix: Relocate the ivy to a cooler, well-ventilated spot in medium, indirect light, away from direct heat sources.
When to worry
You should act immediately; if the webbing covers the entire plant and leaves start dropping rapidly, the infestation is advanced and may be difficult to reverse.

Misting provides only temporary humidity and is generally ineffective at removing a mite colony. Physical washing and oil-based treatments are required to break the infestation cycle.
Speckled leaves will not turn green again, but if treated early, the plant will push out healthy new growth within a few weeks.
