NGREDIENTS: We've added three other ingredients to Perma Guard Fossil Shell Flour (DE) to increase it's effectiveness: flour for better adhesion to the pests, salt to speed up the dessication, and baking soda to soothe the flea bites. All of our DE is completely mined, processed, and bagged in the USA. DIRECTIONS FOR USE: Apply full strength by rubbing into animals' coat as close to their skin as possible. Reapply every 3 days or as needed. A little sprinkled into the pet's bedding is a further deterrent.
