How to get rid of mice in a polycarbonate greenhouse? - briefly
Seal all openings with metal flashing or concrete, install snap or live‑catch traps along wall perimeters, and remove captured rodents immediately; supplement with bait stations and keep the greenhouse free of debris and food residues to prevent re‑entry.
How to get rid of mice in a polycarbonate greenhouse? - in detail
Mice infiltrate greenhouse structures because they can enter through small gaps, chew on wiring, and contaminate plants. Effective control requires a combination of exclusion, habitat modification, and targeted removal.
First, seal all entry points. Inspect the perimeter for holes larger than ¼ inch and apply a durable sealant such as silicone or polyurethane caulk. Install metal flashing around vents, doors, and windows; rodents cannot gnaw through steel. Fit door sweeps and weather stripping to prevent access under openings. Check the polycarbonate panels for cracks and repair them promptly.
Second, eliminate food and shelter sources. Store seeds, feed, and compost in airtight containers made of metal or heavy‑wall plastic. Remove fallen fruit, vegetable debris, and weeds that provide cover. Keep the soil surface clean and consider using mulches that are less attractive to rodents, such as coarse gravel.
Third, deploy physical traps. Snap traps placed along walls, near suspected runways, and close to the plant base are highly effective. Use bait that appeals to mice, such as peanut butter or dried fruit, and position traps perpendicular to the wall with the trigger end against it. Check traps daily and dispose of captured rodents according to local regulations.
Fourth, consider electronic deterrents. Ultrasonic emitters mounted at regular intervals create a hostile acoustic environment for rodents without harming plants. Ensure devices cover the entire interior volume; overlapping zones improve efficacy.
Fifth, apply safe rodenticides only as a last resort. Choose products approved for greenhouse use, place them in tamper‑resistant bait stations, and locate them away from crops and pollinators. Follow label instructions precisely to avoid contamination.
Finally, maintain a regular monitoring routine. Conduct weekly inspections for new gnaw marks, droppings, or nesting material. Record findings and adjust exclusion measures accordingly. Consistent vigilance prevents re‑infestation and protects the greenhouse’s productivity.
