What Are Fleas?
Fleas are small, wingless insects. They live by biting animals and drinking their blood. They like warm places. Fleas can jump very far for their size. This helps them move from one animal to another quickly.
Why Do Fleas Bother Us?
Fleas cause itching and redness on skin. Pets like dogs and cats often get fleas. When fleas bite, they can spread diseases. Fleas also lay eggs on your pet. These eggs fall off and grow in your house or yard.
When is Flea Season?
Flea season is the time when fleas are most active. In many places, flea season starts in spring. It lasts through summer and into early fall. Fleas like warm and humid weather. This is why they come out during these months.
In some areas, flea season can start as early as March. It may last until October or November. In warmer climates, fleas can be a problem all year. They do not like cold weather. When it gets cold, fleas become less active or die.
Why Fleas Come Out in Spring and Summer

How Fleas Grow and Spread
Fleas have four life stages:
