Q. Are there natural ways I can control fleas and ticks if I don’t want to use chemicals?

Answered By

A. I have not had much success with natural options to prevent flea and tick attachment and disease transmission.

There is not a lot of data to support the effectiveness of products such as brewer’s yeast, garlic and diatomaceous earth. The latter is thought to destroy the exoskeleton of fleas leading to their demise and removal. In addition, you must keep in mind that a product labeled as “natural” or “organic” can still be unsafe or harmful to your animal.

Always be careful with any new product you introduce into your pet’s immune system. I would further suggest consulting with your veterinarian before utilizing a natural remedy.
