how big are ticks
Deer ticks are smaller than their counterparts, the dog and lone star ticks. Deer tick nymphs are typically the size of a poppy seed, 1 to 2 mm (.039 to .078 inches) in diameter, while adults range from 2 to 3.5 mm (.078 to .137 inches) and are roughly the size of a sesame seed. An engorged tick may be about 10 mm long.
