Short answer
Fine webbing and speckled, stippled leaves on a Snake Plant are classic symptoms of a spider mite infestation. To fix this, isolate the plant immediately, wash the leaves thoroughly with lukewarm water, and apply insecticidal soap or neem oil every 5-7 days for several weeks.
Dracaena trifasciata is highly resilient, but its thick, waxy leaves can become a target for spider mites, especially in the dry, low-humidity environments often found indoors. While these pests are not typically fatal to a healthy Snake Plant if caught early, they can cause permanent cosmetic damage and weaken the plant's structural integrity if left to multiply.
Spider mites thrive in the dry air that Snake Plants prefer and feed by piercing the plant's cells, leaving behind telltale white or yellow speckling known as stippling. You will notice fine, silk-like webbing tucked into the crevices between leaves or near the base of the plant.
Check: Hold a clean sheet of white paper under a leaf and tap the foliage; if tiny moving specks fall onto the paper, you have an active infestation.
Fix: Thoroughly rinse the entire plant under lukewarm water, then apply insecticidal soap or neem oil to the foliage every 5-7 days for three weeks to break the mite life cycle.
Because Snake Plants are often kept in neglected, very dry corners, environmental factors can sometimes mimic damage. While mites cause active stippling, extreme lack of moisture can lead to tissue death that might look like tiny spots or pits on the leaf surface.
Check: Check the soil moisture level; if the soil is bone-dry and the plant has not been watered in over a month, the leaf appearance may be a response to chronic dehydration.
Fix: Provide a thorough soak, allowing the water to drain completely from the bottom of the pot, and ensure the plant is not sitting in a drafty area.
While less likely in the dry conditions preferred by Dracaena trifasciata, fungal spots can appear if the plant is kept in poor airflow or accidentally kept too damp. These spots are typically more distinct and circular compared to the generalized stippling caused by pests.
Check: Observe if the spots have a dark halo or are spreading quickly despite the absence of webbing.
Fix: Improve air circulation around the plant, prune away the most severely affected leaves, and ensure the soil dries out completely between waterings to discourage fungal growth.
When to worry
If the leaves begin to yellow significantly, show large patches of necrosis, or if the webbing becomes dense enough to cover large portions of the plant, immediate intervention is required to prevent the collapse of the foliage.

Diagnose my Snake PlantWhile systemic granules can be effective, they are often overkill for a localized mite problem and can lead to secondary pest outbreaks; manual washing and contact sprays like neem oil are usually sufficient for Snake Plants.
Usually, no. Spider mites live on the foliage, not in the soil, so replacing the potting mix is unnecessary unless the soil is also degraded or the plant is suffering from root rot.
Unfortunately, no. The speckled stippling is permanent damage to the leaf tissue, but once you treat the mites, the plant will push out new, healthy, uniform green growth.
