Stone martens can be a nuisance when they invade outdoor seating areas, causing damage and leaving behind messes. To effectively prevent these interactions, consider the following strategies:

1. Remove Food Sources: Ensure no leftover food or trash is accessible. Secure garbage bins with tight lids and clean seating areas regularly.

2. Use Deterrents: Install motion-activated lights or sprinklers. Ultrasonic repellents can also discourage martens from approaching.

3. Modify Habitat: Trim overhanging branches and remove dense shrubs near seating areas to eliminate hiding spots.

4. Physical Barriers: Use wire mesh or netting around vulnerable areas. Elevated seating can also reduce accessibility.

5. Natural Repellents: Scatter citrus peels or use commercial repellents with strong scents like peppermint or vinegar.

6. Professional Help: For persistent problems, consult wildlife control experts for humane trapping and relocation.

Combining these methods ensures long-term protection and a marten-free outdoor space. Consistency and maintenance are key to success.
