Spider beetle (probable)

Dry indoor environments, including pantries, cupboards, attics, and stored-food areas; often associated with dust, lint, and old nesting material.

Larvae feed on dried organic matter such as grains, spices, cereals, dead insects, wool, feathers, and other debris. Adults may feed little or not at all.

Usually nocturnal and secretive, moving slowly or feigning death when disturbed. Larvae develop in concealed, undisturbed materials, and adults may appear near windows or lights.

Generally harmless to people and do not bite, sting, or transmit disease. They can contaminate or damage stored foods and occasionally natural-fiber materials; they also help decompose organic debris.
