What should I do if mice have eaten bark? - briefly

Inspect and remove the damaged bark, then install a rodent‑proof barrier (e.g., metal flashing or hardware cloth) and set traps or bait to eradicate the mice. After confirming the infestation is cleared, replace the missing bark with a suitable substitute.

What should I do if mice have eaten bark? - in detail

If rodents have chewed the bark of a tree, immediate action can prevent further harm and support recovery.

First, evaluate the extent of damage. Look for open wounds, exposed cambium, and any signs of sap loss. Record the size of each affected area.

Second, protect the vulnerable sections. Apply a commercial tree wrap or horticultural tape around the damaged zones, overlapping the material by at least two inches to cover the exposed tissue. Secure the wrap with a biodegradable twine, avoiding excessive tightness that could restrict growth.

Third, deter future gnawing. Place rodent‑resistant barriers such as metal mesh or hardware cloth (¼‑inch mesh) around the trunk, extending the protection at least 12 inches above and below the damage. Install bait stations or snap traps at a distance from the tree to reduce the population without harming the plant.

Fourth, encourage healing. Treat exposed cambium with a suitable wound sealant or tree wound dressing, following the manufacturer’s instructions. Maintain adequate moisture by mulching the base of the tree, ensuring the mulch does not touch the trunk directly.

Fifth, monitor regularly. Inspect the wrap and barriers weekly for signs of new activity or deterioration. Replace any compromised material promptly.

Finally, consider long‑term management. Reduce attractants by keeping the area free of fallen fruit, seed heads, and debris. Trim low branches that provide easy access to the trunk. If the infestation persists, consult a professional pest‑control service for a targeted eradication plan.

By following these steps—assessment, protection, deterrence, treatment, monitoring, and habitat management—the tree can recover and the risk of further bark loss is minimized.
