Ever since we moved here 10 years ago we've had summer itches and welts on both of us. We never see mosquitoes and know we don't have bedbugs! We've checked us and our dogs for fleas. We can't find a thing, but from May to Sept we both get covered in red itchy bites. I just noticed we are on the chigger maps, so that may be the culprit. We've never seen any, but just suddenly have new welts every day. Do they bother dogs too? Our dog is super itchy right now.
