Fleas

From the Millennium-Arc

Vacuum. Vacuum, remove the vacuum bag, seal it, and dispose of it immediately outside your home.

Vinegar. A ratio of 1 teaspoon vinegar to 1 quart water (per 40 pounds of pet weight) in their drinking water helps to keep your pets free of fleas and ticks.

Fennel, Rosemary, Red Cedar Shavings, Sassafras, Eucalyptus, or Pennyroyal. Spread leaves or shavings of these plants under and around the pet's bed.
