Huh ...I wonder if this would help because I have a severe nickel allergy, such that I have to eat a low nickel diet or I constantly am flaring up. I'll have to look into it. I already have two buckets of food gradw DE because I used it on the carpet years ago to get rid of the cloth moth larvae that were making their cocoons in the carpet under the furniture ...yuck. It worked but was hella messy to clean up and killed a vacuum filter. XD
