New Jersey’s Dangerous New Neighbors: How Climate Change is Bringing Black Widow Spiders Closer to Your Home

As temperatures continue to rise across the Northeast, New Jersey homeowners are facing an unexpected and potentially dangerous consequence of climate change: the northward migration of black widow spiders. Research published in PLOS One shows that black widow spiders are moving farther north than ever before thanks to more agreeable temperatures, with the northernmost range expanding by over 30 miles in the past 60 years.

The Climate Connection

Climate change is causing a gradual shift in territories of many species, as animals have certain temperature thresholds they won’t tolerate, but rising average temperatures can either push them away or lure them into previously unsuitable areas. Scientists believe that the spread of black widow spiders, which prefer a temperate climate, is directly linked to climate change.

Black widows are already prevalent in New Jersey and are considered the most venomous spider in North America, with venom reported to be 15 times stronger than a rattlesnake’s. Their venom can cause aches, pains, and paralysis of the diaphragm which makes breathing difficult.

Urban Heat Islands: A Spider’s Paradise

The situation is particularly concerning in urban areas. Research on Western black widow spiders in Phoenix showed that urban heat island conditions can be 6°C hotter than natural desert habitats. These spiders have been estimated to thrive more in densely populated areas than in nature due to factors like easily accessible food, buildings that serve well for spider homes, and fewer natural enemies.

Identifying the Threat

Black widow spiders are fairly straightforward to distinguish from other spiders – they are jet black in color, hairless, and may display a red hourglass symbol on the bottom of their abdomen. These spiders prefer to inhabit dark, undisturbed areas such as woodpiles, sheds, and outdoor furniture, creating strong, irregular webs in secluded areas.

Black widow spiders build webs in irregular, gauzy shapes, often low down near ground level, and they have a tendency to hang upside down in their webs. They are reclusive creatures that don’t roam freely in daylight, preferring dark, warm places while staying low and out of sight.

The Risks to New Jersey Families

While deaths from black widow bites are very rare and these spiders prefer to flee rather than bite, encounters do occur. Bites usually happen when a black widow comes into contact with skin, such as when someone picks up clothing with a spider hiding inside or crawls into bed with one hiding in blankets.

The venom contains neurotoxins that affect the nervous system, causing symptoms such as severe pain, muscle cramps, and nausea. Their potent venom can lead to serious complications, especially for those with compromised immune systems or pre-existing health conditions.

Prevention and Professional Solutions

Given the increasing presence of these dangerous spiders, prevention is crucial. Black widows are most active during warmer months, so homeowners should be extra cautious during this time, especially when moving items in garages, basements, or sheds. Wearing protective clothing when venturing into areas where black widows may reside and shaking out clothing and shoes before use are important safety measures.
