In this guide, we’ll discuss how to identify fleas on pets and in your home, explain how long fleas can survive without a host, and provide tips for checking for fleas.

What are Fleas?
Fleas are blood-sucking parasites that feed on animals and occasionally humans. Their flat, narrow bodies and powerful jumping abilities allow them to move easily between hosts and hide in fur, bedding, and carpets. This makes them hard to detect and even harder to eliminate. Fleas reproduce rapidly, going through a four-stage life cycle: egg, larva, pupa, and adult. The pupa stage is particularly resilient, allowing fleas to remain dormant in carpets, upholstery, and crevices for weeks or months. This hidden development makes infestations difficult to spot until they become severe.Signs of Flea Infestation in Your Home
Fleas can invade your entire home, including carpets, furniture, and bedding. Once fleas lay eggs, they spread quickly, making it difficult to eliminate them. If you notice itchy bites on your body or spot small jumping insects, it may be a sign of a flea infestation. Here’s how to recognize and check for fleas in your home.How to Know If Your House Has Fleas?
