Important point to note when using baking soda to kill fleas

If you use baking soda to kill fleas, you have to ensure that the product is still active. To test if your baking soda is active, add it to a few drops of vinegar. The mixture should bubble instantly and continue to bubble up for a few minutes. If this is not the case and the bubbles are forming rather slowly or not forming at all, then it is time to replace your existing batch of baking soda.

Steps for killing fleas with baking soda

To kill fleas with baking soda, you must treat the carpets, bedding as well as the furniture in the household. Failure to do this will render all other flea control products (particularly those used on the pets) ineffective, as the fleas will simply continue to multiply on these breeding grounds.

Yes, baking soda can be used on your dog or cat. In fact, it deodorizes the pet’s fur between baths and also stifles the fleas and other parasites that may be living in it. You can also make a wonderful and inexpensive pet shampoo using baking soda (many shampoos made specifically for pets contain baking soda). Baking soda can also be used on other household pets such as rabbits, ferrets, hamsters, gerbils, chinchillas and guinea pigs.
