Likely flea (image uncertain)

Often found on dogs, cats, wildlife, carpets, bedding, and floor cracks where immature stages develop.

Adults consume blood from mammals or birds; larvae feed mainly on organic debris and dried blood in animal bedding.

Wingless, powerful jumpers that move through fur or fabric and may bite repeatedly. Eggs and larvae commonly accumulate in sheltered host resting areas.

Bites cause itching and allergic dermatitis; fleas can transmit pathogens and animal tapeworms. They are important prey for predators but provide no meaningful household benefit.
