Spiders in New Jersey

How to Spot Spiders in New Jersey

Thirty-nine species of spiders are well documented throughout the state of New Jersey. Some like to spend their time in dark places abundant with insects in addition to smaller areas such as storage boxes, empty shoes, and basements. When it’s cold outside, spiders overwinter in hidden places throughout the home or in protected areas of the landscape. They will become active again in the spring. By October, these pests are most active, as they are preparing to mate. Even big spiders, despite their ghoulish appearance, are relatively harmless to humans. A venomous species to look out for is the black widow which is about the size of a small coin.

Dangers Posed to Humans

Most spiders in New Jersey bite, but only two produce venom strong enough to seriously harm people. For example, the common house spider delivers a painful but otherwise benign pinch, while the bite of a black widow spider delivers crippling effects such as intense nausea, fever, muscle aches, and difficulty breathing. While not venomous, jumping spiders can cause quite a scare, possessing colorful jaws and the ability to leap 10 to 50 times their body height.

Eliminating Spiders from the Household

Spiders are natural predators which help to balance populations of harmful insects such as beetles, flies, and silverfish. However, they become pests upon making their way into the home. During the fall months, grass spiders make their way indoors, and are sometimes mistaken for brown recluses. When managing spider infestations, cultural recommendations work best to reduce spider activity in and around the house.
