Chipmunks in Basement: Live Trap, Mint, Cats

Options

• Live-trap (check legality).
• Mint (peppermint/spearmint) around foundation—rodents hate it.
• Outdoor cats hunt them effectively.

Ultrasonics = Useless

No evidence they work on chipmunks.

Trapping Won’t Stop Re-invasion

Forest edge = endless supply. Focus on exclusion (seal foundation gaps) + habitat modification (remove bird seed, wood piles).
