Question

How long do I leave diatomaceous earth on the lawn after application before watering the lawn?

Community Answer

Whether you have used the wet or dry method of spreading your diatomaceous earth outdoors, it is susceptible to moisture and reapplication is necessary after each rainfall or sprinkler system. Rule of thumb: If you can't SEE the powder, reapply every 3 days or so.

Question

I want to treat lawn that my dog plays on, is DE safe for animals?

Community Answer

DE comes in two forms: non food-grade and food-grade. Non food-grade is safe when applied to a lawn, but any DE that is to be ingested by pets should be food-grade. It is made up of the skeletal structures of tiny organisms whose spines are only harmful to small and delicate parasites. However DE that isn't food-grade might contain chemicals from processing that can harm pets.

Question

My dog was recently diagnosed with hookworms and DE was recommended for spots where feces was left over 24 hours. How do I know it's been effective? Should I spread it all over the lawn instead?

Community Answer

Do not treat any area your dog/s go in with anything. You must treat your actual dog. Then, pick up and dispose of the feces immediately, as the dog got this by ingesting feces. Wash your hands well after treating the dog or collecting feces.

Fit and fill the honey bee openings. Utilize a little piece of folded aluminum foil or a piece of steel fleece to stuff into the opening, and afterward, fix over it with a weatherproof wood fix clay. Paint over the fix when it is dry.
