The highest populations of the wood tick are found in southern Maine in Oxford County and surrounding areas. However, ticks have turned up recently in great abundance in areas north of Oxford County and into Kennebec County. Some wood ticks outside of Maine may carry the organism that causes Rocky Mountain spotted fever, a serious disease that can be transmitted to humans. The symptoms of Rocky Mountain spotted fever are headache, fever, and aching muscles two to 14 days after an encounter with a tick. Two to three days after the fever starts, a rash develops on the wrists and ankles, spreading to the palms, soles, and trunk of the body.
Wood ticks are most likely to be found in open areas with tall grass or brush.
Adults are first noticed in late April and remain to abundant through June. Numbers seem to decline sharply after that, but some occur all summer. It is transported here from areas south of Massachusetts on pets and occasionally on clothes. Although this species is not likely to feed on humans, it has been found in homes- even on beds. Dogs are the brown tick's favorite host and source of bloodmeals.
