How to treat ticks on orchids? - briefly
Inspect foliage regularly, remove visible ticks with sterile tweezers, and treat the plant with a systemic acaricide approved for epiphytic orchids such as «Southeast Acaricide», following the label dosage. Maintain low humidity and improve air circulation to reduce the risk of reinfestation.
How to treat ticks on orchids? - in detail
Ticks on orchids damage foliage and roots, reducing plant vigor. Early detection prevents spread. Inspect leaves, stems, and potting medium weekly. Look for small, brown or reddish insects clustered near growth points, and for fine webbing.
Effective control combines cultural, mechanical, biological, and chemical measures.
-
Cultural practices
• Maintain low humidity in the growing area; ticks thrive in moist conditions.
• Reduce excess organic debris in the potting mix; replace with a well‑draining medium such as bark or perlite.
• Avoid overwatering; allow the substrate to dry slightly between waterings. -
Mechanical removal
• Use a fine brush or cotton swab dipped in soapy water to dislodge insects from leaf surfaces.
• Vacuum the plant gently to capture dislodged ticks, then empty the vacuum bag or canister away from the growing area. -
Biological agents
• Apply predatory mites (e.g., Neoseiulus spp.) according to label instructions; these mites feed on tick stages and reproduce within the colony.
• Introduce entomopathogenic fungi such as Beauveria bassiana; spray a spore suspension on foliage and substrate, ensuring thorough coverage. -
Chemical options
• Select a horticultural oil (e.g., neem or mineral oil) with a concentration of 0.5–1 %. Apply in the early morning or late evening, covering all plant parts, and repeat after seven days.
• If oil treatment proves insufficient, use a systemic acaricide registered for orchid use; follow dosage and safety guidelines precisely, and observe a pre‑harvest interval if applicable.
Preventive steps reduce recurrence.
• Quarantine newly acquired orchids for at least two weeks, inspecting daily for signs of infestation.
• Sterilize tools with 70 % isopropyl alcohol before each use.
• Maintain proper air circulation; fans help lower humidity and discourage tick development.
• Rotate potting media annually, discarding the old substrate to eliminate residual eggs.
Regular monitoring, combined with the outlined interventions, sustains orchid health and minimizes tick damage.
