Insecticides in Fabric
I have always heard that fabric we buy has been treated with insecticides because of its transport into the country from overseas. Most batting, on the other hand, is made in the U.S. and not treated with insecticides. I have never found a dead bug in a bolt of fabric, but I have seen one or two in batting.
If fabric is treated with insecticides, how long can a person reasonably expect the treatment to be effective? Or is it the container that is sprayed and not the fabric?
I wash my fabric, some as it comes in the door, and some just before I use it. I assume I am washing away the insecticide, so any factory or transport protection would be compromised or lost completely.
I am very interested in facts on this subject.
