There are thousands of species of spiders found worldwide. However, in the UK, approximately 600 species can be found. The vast majority are harmless to humans and spiders are generally considered beneficial to the environment. They feed on insects, other spiders and any other prey that they are able to subdue. Spiders do not have a mouth capable of chewing, so typically, they will use digestive enzymes to break down prey before consuming.
Spiders are able to produce silk which is elastic, adhesive and strong. This silk is spun to form a spiders’ web, construct egg sacs and line their dwelling. The webs differ in shape and size, dependent on species. Some species will live in burrows and crevices rather than webs.
The most common methods of entry into an office or home for spiders is through windows or doors that are either open or have cracks. They can also enter through accidentally being contained in other items.
Spiders can always be identified by their eight legs. They have two segments to their body and do not have any wings or antennae. Spiders have three or four pairs of eyes but surprisingly, most species have very poor vision.
Autumn is when spiders are most active and looking for mates. Females produce egg sacs from which the spiderlings emerge. These can be fixed to any surface, hidden in a web or carried on a foreign object.
