There are 39 species of spiders found in New Hampshire, and none of them would be classified as rare. Whether you would come into contact with them is another story, but all of them could become a nuisance or a pest.
So let’s take a look at some of the major groups of spiders found in New Hampshire, where you’ll see them, and the season in which you might encounter them.
The fishing spiders make up this group, and they will generally be found anywhere that calm water is present.
They can be invasive if you have a home-built pond, especially if there are few or no flowing water effects. Some of them may become large enough to catch small decorative fish or tadpoles, but they will also catch mosquito larva, so they could be a valuable asset.
Fishing spiders will only be seen in the spring or summer, and they won’t ever invade your home. But if there is water on or around your property, fishing spiders may be there, too.
Although generically named garden spiders, these types of spiders live outdoors in or near gardens, meadows, or woodlands, and they may even colonize an outbuilding like a garage, woodshed, or greenhouse. Generally, you won’t find them in your house, and they are only around during the temperate months of the year.
Some of the largest spiders in New Hampshire are in this category, like the orb weavers and the black and yellow garden spider, which can get huge. None of them are a threat to a human, and they won’t readily come into a house, preferring to be outside where their most common prey is. But if you have a garden, expect to see one or more of these types spinning a web between the leaves of your plants. Even though they may look scary, they will trap and eat many types of insects that could harm your garden vegetables.
These common spiders will go out of their way to make a home out of your home, and under the right conditions, they will thrive.
Some of the most common types are the jumping spiders, which jump and hop when they move; the daddy long legs, which are named for their incredibly long legs; the sac spider, which is a nocturnal hunter that prowls walls and ceilings; and the common house spider, which looks like a teardrop.
These house spiders can become a pest and will be present all year long, so keep a lookout in basements, crawl spaces, and cellars.
There are three known species of poisonous spiders that may inhabit New Hampshire residences: the Black Widow, the Brown Recluse, and the Broad-Faced Sac Spider.
Widows are known for a red marking on the underside of their abdomen, recluse spiders are brown and have hairy abdomens, and the sac spider has a greyish body with red legs.
Their bite feels like the sting from a bee or a wasp, and in most cases any irritation caused by the bite will go away on its own within 24 hours. However, some people may be allergic to the bites, and if any medical discomfort is felt after an encounter with a poisonous spider, they should be taken to the hospital for further evaluation.
