The larger adult ticks are more easily seen on skin or clothing.
The ones to really worry about are the pre-adult nymphs that are very tiny and usually result in undetected bites and usually are more likely carriers of tick-borne diseases.
Birds, rodents, small game and especially deer are hosts to the diseases. Ticks just spread them to humans...on occasion.
As noted, Picardin 20 for the skin.
