Diatomaceous Earth for Flea Control or Deworming Dogs and Cats, Puppies and Kittens

Food Grade Diatomaceous Earth Flea Control, Safe Diatomaceous Earth Flea Control, Tick Control, Worm Control

Pets: Our best friends come in all shapes and sizes. Protect them with food grade Diatomaceous Earth. When lightly rubbed into their coats or dusted on their premises, it is very effective against fleas, ticks, lice, and other pests on dogs, cats, ferrets, guinea pigs, rabbits and birds, even horses. It can also be used as an organic wormer and will kill any worms or intestinal parasites the pets may have. When using as a de-wormer, mix the food grade Diatomaceous Earth into their food as follows:

  • Large Cats - 1 teaspoon
  • Kittens - 1/4 teaspoon
  • Dogs 100 lbs + - 1-2 tablespoons
  • Dogs 50 - 100lbs - 1 tablespoon
  • Dogs Under 50 lbs - 1 teaspoon
  • Mini dogs - 1/2 teaspoon

I have found it is best to use something savory or that your pet really likes, tuna juice for cats, gravy, milk or anything that is tasty that could be mixed into a paste. 

When worming cats, specially feral groups, you can mix 5 tsps to a can of cat food with some water to get a good consistency and spread over on one dinner size plate and allow several cats to eat at one plate. Usually 5 cats can eat from one plate fairly well. There is no worry one may get more than another, it is safe if overdosed, but this method may take several more days to make use everyone gets enough.

Any pure food grade daitomaceous works for a dewormer and for flea control. I add lemongrass, probiotics and vitamin C to my wormer just for added support. I also add ground lemongrass, rosemary and neem to my flea powder to help repel fleas and ticks.

Veterinary naturopaths Drs. Kim Bloomer & Jeannie Thomason, hosts of the
online radio show, Animal Talk Naturally, have this to say about 
Diatomaceous Earth:

"Our work is based on natural, preventive care for animals so of course we
are always on the lookout for good, quality NATURAL products to help our
clients and our listening audience that won't break the bank. We've long
been proponents of FOOD-grade diatomaceous earth as a natural pest control
for both external and internal use in animals".
