What should I do if mice have appeared in a greenhouse? - briefly
Seal all gaps, eliminate accessible feed, and deploy snap or live traps positioned near activity zones; then inspect regularly to confirm capture. Maintain strict sanitation and habitat control to deter future infestations.
What should I do if mice have appeared in a greenhouse? - in detail
Rodent intrusion in a greenhouse threatens plant health, contaminates soil, and damages infrastructure. Immediate action reduces loss and prevents recurrence.
First, confirm the extent of the problem. Inspect all growing areas, storage rooms, and utility spaces for droppings, gnaw marks, and active pathways. Set up motion‑activated cameras or sticky traps along walls to identify peak activity times and preferred routes.
Second, eliminate food sources. Store seeds, grains, and compost in sealed, rodent‑proof containers. Clean up spilled water and plant material; dispose of waste in tightly closed bins. Remove standing water that may attract insects, which in turn draw mice.
Third, block entry points. Seal cracks, gaps around doors, windows, and ventilation ducts with steel wool, metal flashing, or cement. Install door sweeps and weather stripping on all access doors. Ensure that any openings for irrigation lines or electrical conduits are fitted with metal mesh of at least ¼‑inch aperture.
Fourth, implement control measures. Deploy a combination of the following, placed near identified pathways:
- Snap traps with bait (peanut butter, cheese, or grain) positioned perpendicular to walls.
- Live‑capture cages checked twice daily; captured animals should be released at least 5 km from the facility, following local regulations.
- Electronic ultrasonic emitters, calibrated for the greenhouse’s dimensions, to deter activity during nighttime.
Fifth, monitor and adjust. Review trap catch counts weekly; increase trap density if captures decline. Re‑inspect seals after each weather event and repair any new openings promptly. Maintain a log of observations, control actions, and outcomes to guide future pest‑management plans.
Finally, integrate preventive practices into routine greenhouse management. Schedule quarterly inspections, rotate bait types to prevent habituation, and train staff to recognize early signs of rodent activity. Consistent application of these steps sustains a rodent‑free environment and protects crop yields.
