- More than 2,400 species exist worldwide.
- Attracted to animals by body heat, movement and the carbon dioxide that animals exhale.
- Adults feed on blood; larvae feed on organic debris.
- Found on cats and dogs year-round, but most common during warm and humid weather.
- Life span on dogs is typically more than 100 days – enough time for a pair of fleas and their descendants to produce millions of offspring. Under ideal conditions, assuming no mortality, a pair of fleas has the potential to produce more than 20 trillion descendants in one year.
- Found on opossums, rats, other rodents and humans.
- Can transmit tapeworms from dogs and rodents to other animals and humans.
- Can jump up to 150 times the length of their body.
