How Are Fleas Spread?

Fleas are spread from one animal to another. They can be passed from pet to pet, from bird to bird, and even from human to human. They can survive for a long time on an animal’s fur and skin. After a few days, they will lay eggs and begin to multiply. Eggs will often fall into places where the animals rest.

Fleas rarely live in human hair and most bites are found around the ankles and feet. Because fleas can only jump so high to reach people, they cannot jump very far to land on people. Their feces, which contain digested blood, are excreted as flea dirt. This dirt is why fleas rarely live on humans for long.

You can use insecticides to control fleas and eggs. However, it’s best to apply them to the areas that are most likely to harbor them. Depending on the area, it may take a few hours for the spray to take effect. You can also open your windows while applying the spray. This will help the insecticide dry faster. Another good method is to use nematodes that feed on flea larvae.

Fleas are a nuisance and can pose a health risk to humans. They can transmit tapeworms and cause itchy welts. Additionally, fleas have the potential to spread bubonic plague, a bacterial infection that can infect humans and animals.
