The weaving spiders, which are part of the Theridiidae family, are usually found inside and around houses. Most of them are harmless. There are more than 2300 species of weaving spiders and hundreds of them in Brazil alone. They are known for their irregularly woven webs, which can be useful when identifying. Another good tip is to look at the rounded abdomen, the length of the legs and keep an eye out to recognize this species' preference for living in dark corners.

Step 1. Check for irregular shape

Some house spiders are called weavers because of the shape of their webs. This type of spider creates an irregular web that has no particular shape.

These webs are not round or have a definite pattern, as is the case with other species of web-making spiders. Instead, they can be uneven, irregular and sometimes have large holes in one place and clumps of web elsewhere, giving the impression that someone has tampered with them
