🩸 Feeding And Nutrition

Fleas are bloodsuckers, which means they eat blood! 🩸They use their sharp mouth parts to pierce the skin of their host and drink blood. A flea can eat 15 times its body weight in blood every day! 😲They need blood to grow and produce more eggs. Fleas can survive without food for several months, making them tough little creatures. However, when they do eat, they can cause itching and discomfort for their hosts!

🥚 Life Cycle And Development

Fleas have four main stages in their life cycle: egg, larva, pupa, and adult. 🥚When a flea lays eggs, they are usually found in the pet’s fur or bedding. After a few days, tiny larva hatch out. They are worm-like and look nothing like adult fleas! 🐛Larva eat organic debris and develop into pupae, which are protected in a cocoon. After a week or more, adult fleas emerge to start the cycle all over again! The entire process can take as little as 2 weeks!
