Hi, I'm Pete with Greenhouse Pest Management. We are Atlanta's true natural pest control company. How to treat fleas in linen? Treating fleas in linen is probably one of the smaller steps that you need to do to eliminate an actual flea issue. But as far as the linen, one of the things we need to do is we need to take your linen; your, your blankets, your sheets and stuffs like that; put it in the washing machine; get that stuff thoroughly clean. While that stuff is in the washing machine, the second step is make sure you take your pet to the Vet and get them washed. The third step is to hire a professional or do it yourself. By coming in, using a residual, something that preferably has an IGR. An IGR means Insect Growth Regulator and that takes care of all four life stages; the egg, larva, pupa and adult stages. Remember what you see is only actually one percent of what, of what the actual activity is inside of the home.
