Lifestyle
A house spider sits in a secluded place during the day, hides away from the sun's rays, and goes hunting at night. Uses hunting networks or dispenses with them.

The first substance paralyzes the victim, the second dilutes the insides, which the house spider then sucks. After a while, he throws a funnel, forms a new one in another place.
