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.
In one experiment, most of the nymphal deer ticks exposed to 75% humidity for 8 hours died, even after being returned to 96% humidity. In a typical house environment, unfed deer ticks are not likely to survive even 24 hours. Ticks on moist clothing in a hamper can survive 2-3 days. Ticks that have taken a blood meal may survive a bit longer but certainly not the 30+ days it takes to mature and bite again or lay eggs.
