Ok so I'm currently living with my husbands grand parents & his nan has both a cat & a dog. Well the dog has gotten fleas & I need to treat my bedroom where my corn snake is kept. The dog has been treated with frontline flea treatment & my husbands nan has used flea spray downstairs, the cat is to be treated aswell but I obviously can't use chemical sprays etc in my room because of my baby. I have found something called diatomaceous earth which is a non chemical natural pesticide that works by dehydrating the flea but I'm not 100% if I can use it in the room where my snakey is. It's a food grade item which can be added to pet food to treat worms etc so I dont think it will hurt but I wanted to ask if anyone here who has cats & dogs has any experience with this item (diatomaceous earth)? And if so is it safe to use in the room with my snake? I want to dust my mattress & floor etc.
