You can try different lotions. I've had decent luck with ChiggerX. You can get it at walgreens. There is a lot of misinformation out there about treating chigger bites. The only cure is time. I was infested with the damn things a few years ago after squirrel hunting. Did tons of research. the Missouri department of conservation has the best material if you are interested.
