Do to the warm weather and the increased humidity from all of the rain fall, Chiggars can thrive in our Idaho climate. Chiggers are tiny, six-legged wingless organisms (larvae) that grow up to become a type of mite. Chiggers are found in tall grass and weeds. Their bite causes severe itching.
Chiggers bite humans around the waist, ankles, or in warm skin folds. Bites commonly occur in the summer and fall months.
The main symptoms are:
Itching usually occurs several hours after the chiggers attach to the skin.
A skin rash may appear on the parts of the body that were exposed to the sun. It may stop where the underwear meets the legs. This is often a clue that the rash is due to chigger bites.
Avoid outdoor areas contaminated with chiggers, if known. Applying bug spray containing DEET to skin and clothing can help prevent chigger bites. Wearing long pants and socks can help as well.
