Adults are morphologically similar to other spider beetle species, notably the hairy spider beetle (Ptinus villiger). It is red-brown in colour with yellow hairs, and measures 2.0–4.3 millimetres (0.08–0.17 in) in length. The prothorax is densely covered with pale hairs, while the elytra bear some patches of white scales.

It is a pest of stored foods, with a worldwide distribution, where it may be identified through leaving webbed, granular materials on the stored products. Ptinus fur adults feed on dried and decaying animal and vegetable material. It has also been identified as a pest in museums, damaging stored collections.

It has been found in the nests of birds, notably the Sand Martin.

The optimum temperature for rapid development of Ptinus fur is about 23°C, at which temperature it completes its development in a mean period of 132 days. Larvae of P. fur normally moult three times at 23°Cm but some have an extra moult.

Well defined diapause as mature larvae in cocoons occurs at low temperatures in some individuals of Ptinus fur: at 23°C this lasts about 220 days after normal larvae have pupated; at 20°C the period lasts about 280 days.

The adult beetles live for several months.
