Spent 2 weeks at the beach house in Clearwater Fl and we got bit all over our legs by Chiggers. Yes, sand chiggers.
People are bringing firewood from deep inland and the chiggers catch a ride on the wood so now for the past 3 years, we are getting eaten up with bites. My girlfriend's skin is super sensitive and when she gets a chigger bite, the red inflamed area stays on her for months.
This year I dabbed a drop of straight eucalyptus oil on all her bites (and mine) and the itchy, inflammed bites started to disappear in record time. My stopped itching instantly and were gone in 2 days and hers about 4 days. So now you know. Put Eucalyptus oil in the travel first-aid kit!
