The tip of the tarsus bears claws, which vary in number and size. Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws. Since they do not have antennae, spiders use specialised and sensitive setae on their legs to pick up scent, sounds, vibrations and air currents. [6]
The web of a funnel-web spider Tegenaria duellica. Many spiders, but not all, build webs. Other spiders use a wide variety of methods to capture prey. Web: There are several recognised types of spider web. Spiral orb webs, associated primarily with the family Araneidae; Tangle webs or cobwebs, associated with the family Theridiidae; Funnel webs,
Many spiders build webs specifically to trap and catch insects to eat. However, not all spiders catch their prey in webs, and some do not build webs at all. The term "spider web" is typically used to refer to a web that is apparently still in use (i.e., clean), whereas "cobweb" refers to a seemingly abandoned (i.e., dusty) web. [3]
Crumbley explains that control of spiders comes in two forms: knocking down webs and removing their food sources: Webs can be knocked down with brooms or long dusting wands.

In some cases, spiders may use silk as a food source. [1] While methods have been developed to collect silk from a spider by force, [2] gathering silk from many spiders is more difficult than from silk-spinning organisms such as silkworms. All spiders produce silk, although some spiders do not make webs. Silk is tied to courtship and mating.
Insects as food: Cars can attract small insects, which spiders prey on. Insects may be drawn to food crumbs, lights, or the heat inside the vehicle, providing spiders with a steady food source.
Spiders increase the size of their webs when prey are scarce, and can add extra ornamental pieces to their web in order to attract more prey. [12] Traps can allow organisms to capture larger prey, provide protection from predators, or serve as an area for mating, as seen with spiders. [ 12 ]
