Family Theridiidae – The comb-footed, tangle-web or cobweb spiders are commonly found in houses. They use sticky silk to help them capture their prey, and this group has a great diversity of web shapes and types. They also have a bundle of stiff hairs on each of their fourth legs. The first pair of legs is usually longest with the third pair of legs shortest. The abdomen is generally rounded.
