please help identify this spider before her egg sac hatches!!!!
i recently noticed this spider in my garage, flanked by not one, but two egg sacs. i’m not too keen on having one (poisonous??) spider around, but the thought of all those little baby spiders running around is too much to handle!! can you please tell me what kind of spider this is?? she’s not all that big, round, and definitely shiny. thanks for the site, it rocks!!!

Hi Dana,
Even if you got rid of your Domestic Spider, Theridion tepidariorum, and her eggs, her relatives would most assuredly move in. The Domestic Spider earns her common name. Comstock writes: “Of all the spiders that inhabit our dwellings this is the most familiar, and consequently best merits the title of the Domestic Spider. The tangle of threads can be found in almost any neglected room, throughout the length and breadth of our country; and the species is not limited to our country for it is almost a cosmopolite. This is an exceedingly variable species in colour and markings.” Your specimen has very definite marking unlike any we have previously seen. While all spiders possess venom, the Domestic Spider is no threat to humans. Just let her raise her family and they will help control true pests that enter you home.
