Does Home Depot or Lowes sell Diatomaceous Earth (food grade)?

This is also called fossil shell flour used as a natural way to kill fleas. Please help.

I did call and ask, it's taking forever waiting on the phone, their busy.

Lowes and other home improvement centers carry the filter grade for pools and sometimes those with chemicals for pests.

For flea pest control, the best source for this product is in a health food store, a feed store, or online–even eBay sells it but make sure it is food grade.

Brands of food grade include Perma Guard and Azmira.
