Funnel Weaver Spider Identification


What Do Funnel Weaver Spiders Look Like?

Funnel weaver spiders are a common spider species found in North Carolina and are often confused with wolf spiders or called ‘grass spiders’ because they construct their webs in tall grass, heavy ground cover, and the branches of thick shrubs. They are medium-sized, usually brown or gray, with striped patterns on their legs and a characteristic, elongated abdomen. They are known for the funnel-shaped webs they create.

Signs of a Funnel Weaver Spider Infestation

Indicators of a funnel weaver spider infestation include spotting their distinctive funnel-shaped webs, often found in grass, bushes, flower beds, woodpiles and secluded corners of buildings. Frequent sightings of the spiders near these webs, especially in dark undisturbed areas, can also signify an infestation.


Habitat, Diet, Life Cycle & Bites


Where Do Funnel Weaver Spiders Live?

Funnel weaver spiders typically inhabit areas with ample vegetation, such as gardens and fields. They are also commonly found around homes, in window wells, basements, and walls where their funnel webs can be anchored.

Diet of a Funnel Weaver Spider

Their diet primarily consists of insects that wander into their webs, including flies, mosquitoes, ants, and small moths. They are sit-and-wait predators, capturing prey that enters their funnel-like webs.

Life Cycle of a Funnel Weaver Spider

The life cycle of funnel weaver spiders involves the female laying eggs in a silk sac, often hidden within her web. The spiderlings emerge and grow through several molts to reach maturity. These spiders can live for several years.

Funnel Weaver Spider Bites

Funnel weaver spiders, or ‘grass spiders’ are not poisonous, but are venomous. They contain venom, as all spiders do, but because of the small size of their fangs, they have difficulty penetrating human skin.


Are Funnel Weaver Spiders Dangerous?

Funnel weaver spiders are not dangerous to humans. While they can bite when threatened, their venom is not harmful to humans, and they are generally considered beneficial due to their insect control.

However they are more of a nuisance pest as they molt several times before becoming adults, leaving cast-off skins around the house.

How to Get Rid of Funnel Weaver Spiders?
