A year containing an extra day. It has 366 days instead of the normal 365 days. The extra day is added in February, which has 29 days instead of the normal 28 days. Leap years occur every 4 years. 2016 is a leap year and so is 2020. Except that every 100 years special rules apply.
Best Answer: A average life span is about 1 year. Some live only 3 months, but others can live up to a couple of years. The lifespan of the average tick is about two years. Source(s): http://www.nyc.gov/html/doh/html/ehs/ehs... A fly is 3 days so i'm guessing somewhere around the lines of there.
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.
