There are over 35,000 species of spiders worldwide, and many of them are common household pests. All spiders are predators that mainly feed on insects and other small arthropods. Their body is divided into two regions – the cephalothorax and abdomen, and they have four pairs of legs but no antenna.

Spiders capture their prey by paralyzing or killing it with venom. They inject predigestive fluid into the body of their prey and then suck in the digested liquid food. Remarkably, spiders can survive without food for several weeks, and in some cases, up to four months.

Most spiders are nocturnal, remaining active at night, and will scurry away when disturbed, except when they are tending to their egg sacs during the day. They usually stay hidden and inactive in cracks, crevices, and webs, making them difficult to detect until their population grows large.
