Ive never heard of chiggerX. Chiggers are just a fact of life. I get them all the time even just walking in my yard. But, like someone else said picking blackberries usually earns a bunch.

My grandma used to smear turpentine on my bites when I was little or put me in a bathtub with bleach water. Doubt it helped, but it makes you feel like you've gone full nuke mode on them. I put calamine on my kids who tend to always have their armpits and midsections full of them.
