Can a Rug be Moth Proofed?

Can a Rug be Moth Proofed?

Crispell's solution, which is water based with just a couple of tablespoons of Ammonium Silicoflouride per gallon, is not a vapor-releasing repellent, nor an insecticide. It assumes that moths are present and prevents their eggs from hatching and destroying wool by rendering the wool inedible.

In theory (and perhaps in practice), if all of your stored rugs were properly treated with the Ammonium Silicoflouride/Water solution, it wouldn't matter if moths were present in the local environment. They would not be able to thrive on the wool surface simply because the treated wool is not edible.

Ammonium Silicoflouride is manufactured by Elf Atochem North America, Inc., Hq, 2000 Market Street, 21st Floor, Philadelphia, PA 19103-3222, (215) 419-7000
