Types of Spiders in New Hampshire
New Hampshire is home to several spider species in a range of shapes, colors, and sizes. While most are harmless, some can cause issues for local home and business owners. If you have concerns about a spider infestation, contact the experts at Waltham Pest Services.
Black Widow Spiders
Black widows are the only venomous spider in New Hampshire. Females are about a half-inch in length, though their legs make them appear larger. They also have a reddish-orange hourglass mark on the underside of their abdomens. Males are smaller and do not produce venom. The pests spin webs in dark, quiet places such as sheds, basements, warehouses, and disused storage areas.
These shy arachnids prefer to reserve their venom for prey, but they will attack if provoked. In New Hampshire, spider bites from black widows are rare. However, children and older people can have severe reactions to their venom. Seek immediate medical care if you observe the following symptoms:
- Stomach cramps
- Pain or numbness
This common New Hampshire spider is harmless, but its appearance may be intimidating. Female wolf spiders can be up to an inch long and are larger than the males. As an ambush predator, the pest relies on its sharp eyesight and camouflage to capture prey. Most wolf spiders are dark brown with solid or banded legs, and their coloring helps them blend into their surroundings.
Some New Hampshire wolf spiders hide by burrowing into the ground. They also shelter in woodpiles, under stones, or behind loose siding. When left outside overnight, boots and work gloves are an open invitation for wolf spiders, too. A bite may cause slight pain and swelling, but these arachnids are not dangerous to humans or animals.
