With ticks, an ounce of prevention definitely worth a pound of cure

Anecdotal reports have claimed that deer ticks are out earlier, and are more numerous than in past late winters or early springs – a concern for hunters, campers and even anglers in some situations.
Ticks feed on the blood of animals, birds, reptiles, amphibians, and humans. They can transmit pathogens between animals and humans, including bacteria, viruses, and parasitic worms. The worst of these for Pennsylvanians are Lyme disease, deer tick disease and Rocky Mountain spotted fever.
