Chiggers can also be called red bugs or red spiders. They are very, very small, I have never seen one, but at one time had over 100 bites on my ankles, feet and toes. I am slightly allergic to them and usually have to use a cortisone ointment or if they get to bad have to go in for oral steroids. A friend use to bath her children in water/bleach mixture. Forgot the ratio of bleach to water. She was able to see the mean bugs.
