New Jersey residents, especially those with a penchant for gardening or enjoying the outdoors, should be aware of the presence of black widow spiders. While generally shy and not aggressive, encountering one can be alarming. This guide will delve into everything you need to know about black widows in NJ, helping you identify them, understand their behavior, and take appropriate preventative measures.
What do black widow spiders look like?
Black widow spiders are easily identifiable by their distinctive appearance. Adult females are glossy black with a characteristic red hourglass marking on their abdomen. This marking can sometimes be orange or even a series of red spots. Male black widows are significantly smaller and have less pronounced markings, often with a series of red and white spots on their abdomen. They are generally less threatening than the females. Juveniles are smaller versions of the adult spiders, and their markings might be less defined. It’s important to note that variations in markings can occur, so identifying a spider based on an image alone may not always be accurate.
Where are black widow spiders found in NJ?
Black widows in NJ prefer dark, secluded, and undisturbed places. Common habitats include:
- Woodpiles: These are ideal hiding spots, providing ample shelter and protection from predators.
- Garages and sheds: These outdoor structures often accumulate debris and offer similar conditions to woodpiles.
- Underneath rocks and debris: Areas with loose rocks, leaf litter, or other ground cover can provide excellent refuge.
- Basements and crawl spaces: Dark, damp basements and crawl spaces offer a perfect environment.
- Outdoor furniture: Spaces beneath or within outdoor furniture can harbor these spiders.
Are black widow spiders dangerous?

However, fatalities are rare, especially with prompt medical attention. Children, the elderly, and individuals with pre-existing health conditions are at higher risk of experiencing more severe symptoms.
What should I do if I'm bitten by a black widow?
If bitten by a black widow spider, seek immediate medical attention. Try to capture the spider (if possible, in a sealed container) to aid in identification for medical professionals. Wash the bite area with soap and water and apply a cold compress to reduce swelling. Do not attempt to treat the bite with home remedies.
