I Just Bought the safer brand of diatomaceous earth, which is not the food grade version i believe. Im trying to use it to get rid of centipedes in the house i just moved into. This seems to be the only thing i could find while googling it for 2 days. I plan on spreading this all throughout the home living room, bedrooms, basement, bathroom, everywhere.. so my question is, will it be okay to be in and sleep in the home while this is spread throughout? Also do i vacuum it up after 48 hours?
The danger when handling diatomaceous earth is the dust you don't want to breathe it once it is deposited it settles and there is no more risk until time to vacuum it up. Some swimming pool filters use diatomaceous earth to improve the filter efficiency when pouring it it is best to use a dust mask, I have used it weekly for many years. You don't need the food grade / more expensive type and you can sleep well knowing this is much safer than pesticides in your home, it helps get rid of all kinds of creepy crawlys and can be left indefinatly without negative health risks.
Some years ago there was an outbreak of super-fleas in Northern California. Literally within a few days, my dog and cat were totally infested, as was my home.
I purchased the “food grade” diatomaceous earth and spread it everywhere. It was necessary to leave it on the carpeted stairs and installed carpeting in the livingroom for a few days in order to ensure effectiveness.
I covered the carpet with cheap tarps from the dollar store, and taped plastic sheeting over the stairs. It remained this way for 3 days before the LONG job of vacuuming it all up.
I covered everything for the safety of my dog and cat, i.e., grooming habits. Also to minimize tracking. None of us exhibited ANY symptoms of anything during or afterwards. The result on the fleas was 100%. Infestation eliminated. I did also treat my animals with veterinary flea medications.
The worst bit was the cleanup. Constant changing and cleaning of filters in the vacuum cleaner. It took two days to get it all up. No adverse effects of any kind.
