How to spray a greenhouse against ticks? - briefly
Use a label‑approved horticultural acaricide, diluting it as directed and spraying thoroughly onto foliage, stems, soil, and greenhouse framework; repeat the application after 7–10 days to break the tick life cycle.
How to spray a greenhouse against ticks? - in detail
Effective tick control in a greenhouse requires systematic preparation, appropriate chemical selection, precise application, and post‑treatment monitoring.
Begin by inspecting the structure. Remove plant debris, fallen leaves, and any organic matter that can shelter ticks. Clean surfaces with a mild detergent, rinse thoroughly, and allow the environment to dry. Seal cracks and gaps in the frame to limit tick migration from external sources.
Choose a pesticide registered for greenhouse use against arachnids. Options include pyrethroid‑based sprays, neem oil formulations, or spinosad solutions. Verify label instructions for concentration, re‑entry interval, and compatibility with cultivated crops. If organic methods are preferred, apply diatomaceous earth in thin layers on soil and walkways, then mist with a botanical insecticide.
Prepare the sprayer according to the product’s mixing guidelines. Calibrate the nozzle to deliver a fine, even mist that reaches the undersides of foliage, stems, and the interior surfaces of support structures. Use a pump‑action or backpack sprayer equipped with a low‑volume nozzle to minimize drift.
During application:
- Operate the sprayer at a steady pace, maintaining a distance of 12–18 inches from plant material.
- Cover all vertical and horizontal surfaces, paying special attention to humid zones where ticks thrive.
- Apply in early morning or late afternoon when temperatures are moderate and ventilation is adequate.
- Wear protective clothing, gloves, and a respirator as specified on the pesticide label.
After spraying, ventilate the greenhouse for the period required by the product’s re‑entry interval. Monitor tick activity weekly by placing sticky traps along the perimeter and inspecting plant bases. If counts remain high after the first treatment, repeat the application following the label’s maximum frequency, typically no more than every 7–14 days.
Maintain a regular sanitation schedule: remove wilted foliage, replace soil in containers, and keep humidity levels below 70 % to create an unfavorable environment for ticks. Document each treatment, including date, product used, concentration, and observed efficacy, to refine the control program over time.
