Bedding. A pet’s bed tends to take on a…certain aroma after a while. Chase off that odor in two ways: first, wash whatever you can in the washing machine. Many pet beds, even ones you purchase, have removable, washable covers.
For the parts that can’t be washed, use the baking soda as an odor absorber once again, sprinkling it on the bed, letting it sit for 15 minutes, then whisking the baking soda—and the smell—away with the vacuum.
Fleas. The unfortunate truth of living with pets is that you are likely to see fleas at some point. Soap and water will kill fleas quite effectively on your pet as long as you leave it on there for a few minutes (at least 5).
For fleas in the house, set a trap: dishsoap in a shallow dish near the pet’s bed (or anywhere you’ve seen fleas) will do the trick. The fleas are attracted to the dishsoap, but it traps them. Just empty the dish and refill at least once a week!
