How-To Identify a Venomous Spider
Spiders are scary, and it's even more concerning when you don’t know if the spider you found is venomous. This guide breaks down how to determine if the spider you’re dealing with is a brown recluse, black widow or hobo spider - three of the main venomous arachnids.
1. Take a picture.
Take a quick picture to get a closer look at the spider’s features. Some key characteristics to take note of are: where you found the spider, what the web looked like (if there was one), the spider’s coloring, the shape of its legs, the number and location of its eyes and the positioning of the fangs.
2. Determine if it is a brown recluse spider.
The Brown Recluse is more common in the Midwest and Southeast United States and is mainly identified by the dark brown violin shape on it back. You are likely to find this spider in warm, dry and dark environments, and it will bite if it feels trapped or threatened. This spider’s venom can cause severe allergic reactions.
3. Determine if it is a black widow.
Black Widows can be found throughout the United States, but are most common in the South and Western states. They are black with a red hourglass pattern on its underside.These spiders are found around wood piles, under eaves, in boxes and other areas they deem safe. Black widow spiders do bite when they feel threatened, causing two puncture marks on the skin and immediate pain at the bite site.
4. Determine if it is a hobo spider.
The Hobo Spider is found in the Pacific Northwest region of the United States. They try to hide behind furniture, in closets, in stacks of firewood, and they build their webs in holes, cracks and other open areas. You can identify a hobo spider by the yellow markings on its abdomen. If threatened, the hobo spider will bite, causing a bite that will become noticeable over time.
5. If it is not a brown recluse, black widow or hobo spider, it is highly likely the spider is nothing but a nuisance.
