Description
An arthropod member of the order of Arachnida. Spiders are distinct from insects in that they have eight legs (not 6) and a two-part body (not 3). About 34,000 species of spiders exist with some on every continent in the world. Spiders spin a strong silk thread as a snare for their prey. They feed almost entirely on insects. The presence of spiders in a storage area usually indicates that insects are also present. Spiders, however, do not pose major dangers to artifacts themselves.
Spider excrement does contain small amounts of uric acid plus, unless removed on a regular basis, it will quickly dry and seal the area from the atmosphere that would otherwise gradually patinate the metal. There are several species of regular indoor 'culprits' but all of them make webs of some sort.
