Figure A Figure B Don't take flea problems lightly.
Many animals are allergic to flea bites and can become ill if flea problems go untreated.
Before you can control flea problems, it helps to understand the life cycle of the flea. The adult flea jumps on an animal and makes its meals from the animal's blood. The female flea then lays eggs. Each egg hatches into a larva, which feeds on the animal, spins a cocoon and is transformed into a pupa. The shell of the pupa is very tough and durable, protecting the flea until it becomes an adult anywhere from a week to a year later.
