Poisonous spiders in NJ
If you are trying to identify a spider you found in NJ, your first question is probably if it can hurt you. And while almost all spiders in the world are venomous (not poisonous), only very few are considered medically significant. In New Jersey, there is only one group of medically significant spiders: black widows.
Black widows in NJ
There are two species of black widows in New Jersey: the northern black widow (Latrodectus variolus) and the southern black widow (Latrodectus mactans). Both species look very similar. Let’s have a look at the primary identification marks – you can find some pictures below:
- Black widows are primarily black. If the spider appears brown or purple, you are most likely looking at a false black widow (Steatoda grossa).
- They have a large round and shiny abdomen.
- Black widows have a red hourglass shape on the underside of their abdomen.
- They may have some red or white markings on their back.

If you are bitten by a black widow, you should get medical attention immediately. Symptoms include local pain, nausea and other flu-like symptoms. Put ice on the bite area but don’t put on a tourniquet. Black widow spider bites are usually uncomfortable but are usually not deadly. Keep in mind that around 10 times as many people die from bee or wasp stings in the U.S. each year than from spider bites. Still, medical attention is advised.
Are there brown recluse spiders in New Jersey?
You should never say never but generally, there are no brown recluse spiders in New Jersey. Brown recluse spiders prefer warm and dry habitats and are mostly found in the Southern United States. Their natural range goes as far northeast as Southwestern West Virginia. A long way from New Jersey.
Even though everyone in New Jersey knows someone who knows someone who has seen or has been bitten by a brown recluse, most of these sightings are other brown spiders. Harmless and completely different-looking wolf spiders, fishing spiders and other house spiders are often confused with brown recluses. Simply because they are brown. Well have a look at them further down on this page.
Here is a picture and more information about brown recluses. However, if your spider doesn’t have a dark brown fiddle on its back, you are definitely not looking at a brown recluse.
