Workstead
Being just north of you around Paragould, i can certainly sympathize with you as this seems to be a bad year for chiggers.
What i've found works best for me is first off, spray the potentially exposed skin with a good insect repellant, deep woods off for example.
next i spray my clothing with a high quality horse spray. any that contain pyrethrins will work, (i use Pyranha) but spray it only on the outer clothing, sock cuffs, pant cuffs, around the waist, and so on. (as a plus its one of the best i've found for the horses too)
Dont forget shirt collars and hats also.
As long as i remember this procedure i get very few chigger "bites".
If i've been out in the grass, i try to shower asap when i come in, try spraying yourself down with a household cleaner such as 409 then soap down and rinse. the ammonia in the household cleaner helps kill off any chiggers or ticks. and don't forget to not put the same clothing back on, as it could have stray chiggers looking for a meal.
the best i've found to temporarily kill the sting and itch of bites is absorbine jr. and i've heard preperation H is effective in numbing the bites though i havn't tried it.
