Perlite was a less dusty substitution I tried for the sand.
Lawn fabric was a substitute for women's hosiery.
What really worked for me was Bti or mosquito dunks in my watering container. This version of Bt is on the organic approved list, but I was still nervous about the random, unlisted ingredients used to hold the little cakes together. I'm hoping the hydrogen peroxide will be a safer, much cheaper solution for treating the soil.
Thanks again (to the original poster) for sharing the great info.
