i think chiggers are waayyyyy to small to see, but could be wrong. I kno deer and other various ticks are almost to small to see, and bite you.I jus got rid of two leg fuls of chiggers. nuthin makes me madder, except maybe skeeters. i use a thermacell to wipe those out tho, so now i need to fight the ticks and chiggers. never ending and losing battle in my case tho.
