The nature of fleas is to seek out a host and feed off its blood. Pets are common targets because the fleas can jump from the ground onto their bodies and then hold on for the ride.
They may also catch a ride on the backs of other pests, such as rodents, and will seek out a host body to feed on. This can be a problem for both the pets and the people living in a home, especially if the rodent is evicted and the fleas remain.
Fleas can cause a variety of problems for pets and people, including:
- Itching and swelling
- Allergic reactions
- Transmission of disease
- Time, money, and effort needed for removal
