You can buy it from any pesticide store or online web store like Amazon, eBay, Walmart, etc., and avoid potentially hazardous chemicals. On Amazon, its price is between $15 to $50 depending on the size of the packet or quantity of DE. Read carefully the instruction given on the label and apply in your home accordingly.


Open the packet and spread it like dust on the floor, and keep it like this for 2/3 days. Then vacuum it thoroughly to remove DE from the places you apply.

Then simply Vacuum everything and start using the mattress again.
