Skunks, Raccoons, and Groundhogs: Integrated Lawn and Structure Protection

Grub-Related Lawn Damage

Skunks and raccoons dig for grubs and earthworms. Even after grub treatment, they may continue foraging for 1–2 weeks. Ensure grub control was applied correctly and at the right time (early summer for preventive, late summer for curative).

Groundhog (Woodchuck) Management

Trapping: Most Effective

• Use 10×12×32 in. single-door cage trap.
• Bait with cantaloupe, apple, or fresh greens.
• Set at burrow entrance or travel path.
• Check state laws: relocation often illegal; euthanasia may be required.

Verification of Removal

Stuff newspaper in burrow. If undisturbed 4–5 days (good weather), fill with soil and cap with hardware cloth.

Exclusion for Sheds/Decks

• Trench 12–18 in. deep around structure.
• Install 1/2-in. hardware cloth, bent outward at bottom.
• Attach one-way door over main entrance for 3–5 days, then seal permanently.

Repellents and Deterrents

• Coyote urine: May reduce crop damage but not eliminate; expensive; requires frequent reapplication.
• Dried blood/bone meal: Short-term perimeter deterrent.
• Ultrasonics, mothballs, ammonia: Ineffective.

Key Principles

• Remove attractants: secure trash, pick up fallen fruit, control grubs.
• Act before spring breeding (Feb–Mar).
• Combine methods: trapping + exclusion + habitat modification.
