How can I kill a tick in a greenhouse? - briefly
Use a greenhouse‑approved acaricide applied at the label‑specified concentration, then discard any heavily infested plant parts. Maintain strict sanitation and conduct regular inspections to prevent recurrence.
How can I kill a tick in a greenhouse? - in detail
Ticks can survive in greenhouse environments where humidity, shelter, and host animals are present. Effective eradication requires a combination of chemical, biological, cultural, and physical measures applied systematically.
First, identify the infestation level. Use a white‑paper drag or sticky traps placed on benches and floor surfaces. Count captured specimens to gauge severity and monitor progress after treatment.
Chemical control
- Apply a registered acaricide formulated for indoor use, such as a pyrethrin‑based spray or a carbaryl concentrate.
- Follow label dosage precisely; treat all plant foliage, soil surface, and structural crevices.
- Repeat applications at 7‑day intervals for three cycles, as ticks may hide in protected areas and emerge later.
- Ventilate the greenhouse for at least 30 minutes after each spray to reduce residue buildup.
Biological control
- Introduce predatory mites (e.g., Neoseiulus californicus) that attack tick larvae and nymphs.
- Maintain a temperature range of 20‑25 °C and relative humidity above 60 % to support predator activity.
- Combine with a low‑dose horticultural oil to weaken tick populations without harming beneficial insects.
Cultural practices
- Remove and dispose of decaying plant material, mulch, and any organic debris that provide refuge.
- Trim dense foliage to improve air circulation and lower humidity levels that favor tick development.
- Implement a schedule of regular sanitation: sweep floors, clean drip lines, and wipe down benches weekly.
Physical methods
- Use a high‑temperature steam gun (≥ 100 °C) on soil surfaces and potting media for 10 seconds per spot; heat kills all life stages on contact.
- Install ultraviolet light traps near entry points to capture adult ticks attracted to light.
- Seal cracks, gaps, and ventilation openings with silicone caulk to prevent re‑entry.
After treatment, conduct a post‑control assessment using the same drag method. If tick counts drop below the detection threshold, maintain preventive measures: continue regular cleaning, monitor humidity, and rotate acaricide classes annually to avoid resistance.
