How to make a tunnel for rats? - briefly
Construct a PVC or sturdy cardboard conduit with a smooth interior, appropriate diameter, and sealed ends to prevent escape. Provide ventilation holes, support the tunnel within the enclosure, and position entry points to encourage exploration.
How to make a tunnel for rats? - in detail
Constructing a functional passage for rodents requires careful planning, appropriate materials, and precise execution.
Begin with a clear design. Measure the intended length, diameter, and curvature to accommodate the target species’ size and movement habits. A diameter of 5–7 cm allows comfortable travel while preventing blockage. Ensure the tunnel’s route avoids sharp bends; a gentle curve with a radius of at least 15 cm maintains flow.
Select materials that resist chew damage and are easy to clean. Options include:
- Rigid PVC pipe, wall thickness 3 mm, cut to length and sanded to remove burrs.
- Galvanized steel conduit, sealed at joints with rust‑proof silicone.
- High‑density polyethylene (HDPE) tubing, flexible for curved sections, reinforced with internal wire mesh.
Prepare the site. Excavate a shallow trench, depth 10 cm, to embed the tunnel and protect it from external predators. Lay a waterproof membrane at the bottom to prevent moisture ingress. Place the pipe or conduit in the trench, align sections with solvent‑welded or threaded couplings, and seal each joint with silicone caulk to eliminate gaps.
Install entry and exit points. Fit removable caps at both ends, secured with lockable latches to allow cleaning while preventing escape. Fit a small ventilation grille at each cap to maintain airflow and reduce humidity buildup.
Test the structure. Introduce a few test subjects, observe travel time, and check for signs of stress or blockage. Adjust lighting, temperature, and humidity within the tunnel to match the preferred environment of the rodents.
Maintain the passage regularly. Inspect joints for wear, replace damaged sections, and clean interior surfaces weekly with a mild disinfectant solution. Record observations of usage patterns to refine dimensions or material choices in future projects.
