Adult fleas live off the blood of animals and are very difficult to kill. They have hard bodies that make them difficult to 'squish'. Fleas can jump distances of up to 1 metre (3.2 feet). A female flea can lay between 20-30 eggs in one day and she can continue laying that many eggs for between 6 and 9 months. If she lives for 9 months she'll have produced 8,000 eggs. If half of these fleas are females and start laying eggs, this will result in about 500 eggs per day being laid or 15,000 eggs per month!
Ancient Tuberculosis Identified?
Ancient Tuberculosis Identified? Paleontologists looking for the origin of
tuberculosis (TB) in humans have found evidence that the New World
form of TB may have originated in the Old World with animals that
crossed the Bering Land Bridge more than 17,000 years ago. Those
animals could then have passed the infection on to early Americans
who hunted them. 5 NOVEMBER 1999, P. 1071
