Why Do Fleas Bite More When They Are Dying?

Fleas are bloodsucking parasites. They are reddish brown, about an eighth of an inch long, and have long claws on their legs. Their adaptations allow them to travel through hair shafts. They also have spines on their legs, back, and mouth.

Many flea control products are available for dogs and cats. Some contain permethrin, a synthetic chemical that can kill fleas. Other products include pyrethrin, which is safe for humans and pets. It is also effective against cat fleas.

When fleas bite, they may be trying to flee the area. These fleas may jump off the animal, trying to escape the toxicity. If you notice an increase in biting, you should treat the fleas right away. If you wait too long, the fleas will hatch and you’ll have to treat them again.

Adult fleas have four stages. They feed off the blood of their host and lay eggs in their fur. When the host is dying, they will stop biting. The larvae will then live in the host’s blood. Eventually, the eggs will fall off and lay their eggs.

The life cycle of fleas takes about two to three weeks. They will go from egg to larva to adult flea. In between, they will be dormant for months before they bite again. They may also behave agitated.
