Understanding Black House Spiders

Habitat and Behavior

Black house spiders (Badumna insignis) are known for their preference for dark and secluded spaces. Typically found in the crevices of window frames, under eaves, and within unused corners of buildings, they weave sticky, tangled webs to capture their prey.

  • Natural habitat: They thrive in outdoor environments but can adapt to indoor spaces if conditions are favorable.
  • Interaction with humans: Rarely aggressive to humans and tend to avoid high-activity areas.

Diet and Prey

Primarily, black house spiders feast on a variety of insects, including flies, mosquitoes, and other small bugs. Their presence can inadvertently aid in controlling pest populations within homes.

  • Predatory behavior: They show that they have less need to go far from their established areas by using their webs to catch prey.

Do They Climb into Beds?

The idea of black house spiders venturing into human beds is a concern grounded more in fear than in fact. Given their preferred habitats and feeding habits, these spiders have little reason to climb into beds intentionally.

  • Accidental encounters: On the rare occasion a spider is found in a bed, it is typically accidental, perhaps in pursuit of prey or if disturbed.

Preventive Measures

Implementing a few simple strategies can greatly minimize the likelihood of encountering black house spiders in your bed:

  • Maintain cleanliness: Regular cleaning and decluttering reduce hiding spots for spiders and their prey.
  • Seal openings: Ensuring windows, doors, and walls are sealed can prevent spiders from entering.
  • Control outdoor lighting: Minimizing lights that attract insects can indirectly reduce spider attraction to your home.

Further Preventive Measures

Beyond the initial steps outlined previously, there are additional strategies that can further deter black house spiders from entering your sleeping area:

Minimize Attractants

  • Reduce clutter: Clutter provides hiding spots for spiders and their prey. Keeping your living space tidy can discourage spiders from settling in.
  • Use essential oils: Certain essential oils, like peppermint, are believed to repel spiders. Applying these around potential entry points can act as a deterrent.

Professional Pest Control

  • Regular inspections: Having a professional pest control service inspect your home can help identify and seal potential entry points for spiders.
  • Targeted treatments: Professional exterminators can provide treatments that specifically target spiders, reducing their population around your home.

Frequently Asked Questions

Do black house spiders pose a danger to humans?

  • Generally harmless: Black house spiders are not considered dangerous to humans. Their bites are rare and typically result in no more than mild, localized pain.

Can black house spiders be beneficial?

  • Natural pest control: By preying on insects, black house spiders can help control pest populations in your home, serving as a form of natural pest control.

How can I safely remove a black house spider from my home?

  • Capture and release: Using a glass jar and a piece of paper, you can safely capture and release the spider outside, away from your home.

What are the signs of a black house spider infestation?

  • Webbing: An increase in webbing around your home, especially in dark, undisturbed areas, might indicate the presence of black house spiders.

Black House Spider Pennsylvania
17, Feb 2024
Black House Spider Pennsylvania

There are several different kinds of spiders that Pennsylvanians frequently come into contact with, with the black house spider being one of the most common. These spiders, scientifically named Badumna insignis, are distinguished by unique traits and habits. To live in harmony with these frequently misunderstood animals, homeowners must have an in-depth knowledge of these spiders. Let’s explore the habits, distinguishing characteristics, and practical management strategies of black house spiders.


Pennsylvania’s black house spiders are distinguished by their glossy black bodies and bulbous abdomens. Their undersides may have a reddish-orange mark, and their legs are usually dark brown or black in hue. Males are typically smaller than females, with adult females reaching body lengths of up to half an inch. Juveniles often have a paler complexion and a less shiny look than adults. These spiders are typically found in or near human homes, especially in isolated, dark spaces like attics, garages, and basements.

Habitat and Behavior: 

Black house spiders are typically found living in man-made structures, as their name suggests. They create erratic, knotted webs in congested spaces, behind furniture, and in corners. Insects such as flies, mosquitoes, and beetles make up the majority of the unsuspecting prey that these webs trap and shelter. Black house spiders are normally timid and non-aggressive toward humans, despite their frightening look. They are not thought to have venom that is medically significant to humans; at worst, it will cause moderate irritation. They will only bite if provoked or threatened.


Male black house spiders perform complex courtship rituals in an effort to attract females. Black house spiders reproduce sexually. Females lay their eggs in silken sacs that are kept safe in remote areas after mating. Numerous eggs can be found in each sac, and after a few weeks, the eggs hatch into spiderlings. Before being fully grown, these spiderlings go through multiple molts, during which time they scatter to create their own homes. 

Management and Control:

Although black house spiders help manage bug populations, some people find it uncomfortable to have them in their homes. Homeowners can use a few preventative steps to control infestations and discourage these spiders from accessing living areas:

  • Regularly clean and declutter indoor spaces to eliminate potential hiding spots.
  • Seal cracks and crevices in walls, windows, and doors to prevent spider entry.
  • Install screens on windows and doors to prevent spiders from entering the home.
  • Use vacuum cleaners to remove webs and spiders from indoor areas.
  • Reduce outdoor lighting, as it attracts insects which, in turn, may attract spiders.

For severe infestations or if there is concern about potential spider bites, it is advisable to seek assistance from pest control professionals who can safely and effectively manage the situation.


In Pennsylvania, black house spiders are a common sight in homes and serve an important role in managing insect populations while living with humans. Homeowners who comprehend their actions, recognize important traits, and put good management techniques into practice can preserve a peaceful living environment. By accepting their coexistence and implementing the appropriate safety measures, residential areas can maintain a healthy environment.
