What's eating my peperomia?

Peperomia's thick, succulent-like leaves make it relatively resistant to pests, but fungus gnats are a frequent problem when soil stays too wet. Mealybugs occasionally colonise stem joints, and spider mites can appear in very dry indoor air. Overall pest pressure is among the lowest of common houseplants.

Larvae feed on roots, causing wilting and yellowing leaves; tiny flies hover over moist potting mix. Allow soil to dry completely between waterings; apply Bti drench and yellow sticky traps. Switching to a well-draining mix helps prevent recurrence.

White waxy clusters in stem nodes and at leaf bases; leaves may yellow or drop. Remove with an alcohol-dipped cotton swab; follow with neem oil spray on the full plant every 7–10 days.

Faint stippling on leaf surfaces and minimal webbing, most likely in very low humidity. Wipe leaves, increase humidity, and spray insecticidal soap; repeat twice more at weekly intervals.
