1 doctor weighed in: Lyme disease bullseye how long does it last? 1 doctor weighed in Want a second opinion? While the length of time the bullseye may last it is usually fairly transient and is gone within 7-10 days at most.
Sometimes these ticks stay on a pet's body although they are dead because head and mouth parts remain lodged in the skin. The Ixodes tick that spreads Lyme disease has a 2-year life cycle. It sucks enough blood from a mouse, deer, dog, or human to survive through larva and nymph stages of growth. After two years, the tick reaches adulthood, feeds again, and lays 2000 eggs in the grass.
