People in China noticed birds bathing clay dust to ensure mites in their feathers and started using DE as a form of pest controller to mime that naturalbehavior . That was 4,000 year ago , and it ’s still around as a pest treatment today .
When you and I touch diatomaceous dry land , it feels chalky and smooth – like dried clay in our hands . But for belittled , cushy - bodied louse like aphids and mites , DE is unbelievably terrible .
