Natural Habitat

Homes, carpets, pet bedding, upholstery, and outdoor areas frequented by cats, dogs, or wildlife.

Diet & Feeding

Adults drink blood from mammals and occasionally birds. Larvae feed mainly on dried blood and organic debris in the environment.

Behavior Patterns

Wingless, laterally flattened, and exceptionally strong jumpers; adults hide in fur and can rapidly infest indoor spaces. Eggs and larvae develop off-host, especially in warm, sheltered areas.

Risks & Benefits

Bites cause itchy papules and may trigger flea-allergy dermatitis; fleas can transmit pathogens and tapeworms. They provide limited food for predators but are primarily household and veterinary pests.
