Likely flea

On pets or wildlife and in their bedding, carpets, and other resting areas.

Adults suck blood from mammals or birds; larvae feed on organic debris, including adult flea feces.

Wingless, laterally flattened, and adapted for jumping; eggs and larvae usually develop off the host. The image is small, so identification is tentative.

Bites can cause itching or allergic reactions, and some fleas transmit pathogens; they have little direct benefit to people.
