4. Lice and fleas lay their eggs in dust and litter; consequently the sleeping
quarters should be cleaned and disinfected regularly.
5. Eggs of these parasites hatch in about ten days in warm weather, but may
require three months or longer to hatch when the weather is dry and cold.
6. Dipping kills the parasites but does not destroy the eggs. It is necessary to
