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!

Mondo bugs The total weight of insects on Earth is much
greater than the weight of any other group of animals! Insects are
also among the very few species which feed on humans. Carrying
diseases, such as malaria, also makes them responsible for millions
of deaths each year. However, in some countries, insects provide up
to 10 per cent of the protein in human diets! 5 MAY 2000
