What Are Fleas?
Fleas are small insects. They live on animals like dogs, cats, and even wild animals. Fleas suck blood from their hosts. This blood helps fleas live and grow. Fleas can jump very high. This helps them move from one animal to another.

How Do Fleas Live?
Fleas have four life stages:
- Egg – Flea lays eggs on the animal or in the environment.
- Larva – Eggs hatch into tiny larvae that live in dirt, carpet, or soil.
- Pupa – Larvae make a cocoon and become pupae.
- Adult – Adult fleas come out of the cocoon and jump onto animals.
Each stage can last for days or weeks. The cycle helps fleas survive in many conditions.
Do Fleas Like Cold Weather?
Fleas like warm places best. They grow fast when it is warm and humid. Cold weather slows down their life cycle. But fleas do not die immediately when winter comes.
Fleas can survive indoors where it is warm. They hide in carpets, bedding, and furniture. They wait for the weather to get better. So, fleas can stay alive even in cold months.
Can Dogs Get Fleas in Winter?
Yes, dogs can get fleas in winter. Fleas do not disappear just because it is cold. If your dog spends time outside, it can catch fleas. Fleas may come from other animals or places.
Even if your home is warm, fleas can live there. They can jump on your dog anytime. So, winter does not stop flea problems completely.
Where Do Fleas Hide in Winter?
