At Walmart, I found 3 GIANT sheets of "painters plastic" and it was only like $1.32. It's plastic you put on the floor when you are painting. Well I have a twin bed and it was definately big enough to cover a double or queen. So I used all 3 sheets, and wrapped the top, bottom, sides, everywhere of my mattress. Then I put my sheets over it, and left the plastic there for 3 weeks. And I washed my sheets every single day for a week after my Permethrin treatment.
