A pest of livestock and wildlife. During early fall it is often the most common tick
on deer and cattle. May be found along paths, trails, and roadways. Lyme disease,
caused by a spirochetal bacterium Borrelia burgdorferi, may be transmitted by the
bite of Ixodes scapularis.
Adults become active in late September and October and are present until March or
April. The preferred host for larvae and nymphs is the white-footed mouse, while adult
ticks prefer to feed on white-tailed deer. Ticks can feed on humans at any stage,
but most often the nymph transmits the spirochete. Animal studies have shown that
Ixodes ticks must remain attached for at least 24 hours in order to transmit B. burgdorferi.
Body with tear-drop shape and relatively small size. Dorsal sheild is blackish while
the body behind it is reddish-brown which fades to grey on engorged specimens.
