1. Establish Clear Pet Policies: First and foremost, decide if you will allow pets and under what conditions. If you choose to accept them, make sure to clearly communicate your policies to guests.

2. Provide Specific Cleaning Items: Supply lint rollers, rubber gloves for picking up hair, and powerful vacuums that can handle pet hair.

3. Protect Furniture: Use washable covers on sofas and chairs to protect them from hair and make cleaning easier.

4. Regular Deep Cleaning: Include deep vacuuming and washing of all fabrics, such as curtains and cushion covers, which may accumulate hair, in your cleaning routine.

5. Air Filtration: Consider installing HEPA filters in your air conditioning system to capture hair and allergens.

6. Communication with Guests: Encourage guests to take care of their pets by regularly brushing them to minimize the amount of hair.

7. Specialized Cleaning Service: If possible, offer an additional cleaning service during the stay for properties that accommodate pets.

By implementing these measures, you can keep your properties free from pet hair, ensuring the satisfaction of all your guests, with or without pets.
