Chigger bites
Chiggers are larval form of a type of family of mite (arachnids) called Trombiculidae.
First show up as annoying red bumps followed by itch, spreading
from feet and ankles upward to waistline and groin.
Itching peaks 1-2 days after bite occurs.
Women and children get more bites than men.
To avoid being bitten, use mosquito repellents. Sulphur containing compounds are the gold standard for prevention, but are not used much for obvious reasons.
Clear heavy brush around house. Chiggers rarely habitate well groomed outdoor areas and surfaces hotter than 99 degrees.
Best precaution is to take warm soapy bath with plenty of scrubbing ASAP after exposure.
Treatment includes possibly lotions/creams like what our patient tried OTC, but only solution is tincture of time (takes 1-2 weeks for lesions to resolve).
North American chiggers do not carry any disease.
Only real danger from chigger bites is secondary infections that develop after excoriating with dirty fingernails.
