Welcome to the Dirt Doctor site!
If you look at the home page, right under the video box, you'll see a green button that is the link to the Library of Organic Information. Click on it and you'll find information about many topics, including
treatments for chiggers.
In the "for what it's worth" category, for years I've used a couple of skin care products to repel chiggers (Avon Skin So Soft and Jean Nate after bath liquid). Avon's Skin So Soft has a new insect repellent formula called Avon SKIN-SO-SOFT Bug Guard PLUS IR3535® Insect Repellent.
You can find it at Amazon and Avon and other places. The extra ingredient is "Picaridin" which comes up in a search as
this. It's supposed to be as or more effective as DEET. I'm going to run this product by Howard to see what he thinks, I just heard about it last week.
