How to get rid of spider mite on Adenium? - briefly
Apply insecticidal soap or neem oil to the affected foliage, spraying thoroughly and repeating every 5–7 days until mites disappear; isolate the plant and keep humidity low to prevent reinfestation.
How to get rid of spider mite on Adenium? - in detail
Spider mites commonly attack Adenium foliage, causing stippled leaves, yellowing, and webbing. Early detection relies on inspecting the undersides of leaves with a magnifying glass; the presence of tiny moving specks confirms infestation.
Physical removal reduces population quickly. Rinse the plant with a strong stream of lukewarm water, focusing on the leaf undersides. Follow with a soft cloth or cotton swab dipped in soapy water to wipe visible mites and webs. Repeat the wash every five days until the infestation subsides.
Cultural measures limit mite reproduction. Keep the plant in a location with bright, indirect light and good air circulation. Maintain soil moisture at a consistent level—neither soggy nor bone‑dry—to prevent stress, which makes the plant more susceptible. Increase ambient humidity by misting or placing a tray of water nearby, especially in dry indoor environments.
Organic treatments provide effective control without harming the plant. Apply horticultural oil (e.g., neem or mineral oil) at a concentration of 1–2 % v/v, spraying both upper and lower leaf surfaces until runoff. Repeat the application weekly for three to four applications. Insecticidal soap, prepared at 2–3 % concentration, can be used as an alternative; ensure thorough coverage and reapply every seven days.
If infestations persist, a synthetic miticide may be necessary. Products containing abamectin or spiromesifen are labeled for use on ornamental succulents. Follow the manufacturer’s label for dosage (typically 0.5–1 ml per liter of water) and apply no more than three treatments, spaced ten days apart, to avoid resistance buildup.
Preventive monitoring is essential. Inspect new plants before introduction, quarantine any specimens showing signs of mites, and clean tools regularly. Avoid excessive nitrogen fertilization, which encourages rapid leaf growth favored by spider mites. Regularly prune heavily infested foliage and dispose of it away from healthy plants.
Combining prompt mechanical removal, consistent cultural practices, and targeted organic or chemical treatments eradicates spider mites from Adenium and reduces the likelihood of recurrence.
