I live in the chigger infested Pine Lands of NJ. I have a farm with 36 acres of chigger infested woods. I have had more ticks and chiggers in me than I could ever count. I don't understand why I have never been diagnosed with Lymes disease. My hunting partner has had four bouts of it.
I am actually starting to build up an immunity to the chigger bites and they don't bother me as much as they used to. I used to have an allergic reaction and the bites lasted for 6 months.
It is probably too late, but don't scratch them and put on Chigarid.
Since I know, if you are like me you scratched them and opened them up, get Chigarid and put it on each bite. It is the only thing I have found to relieve the annoying itching and burning.
You can get Chigarid in most chain pharmacy stores. I am looking at a bottle as we speak, since I have an archery range in the chigger infested woods and just got infested again like you.
Good luck, Chigarid all the way!
