Have you spotted a black and white spider crawling across your wall, resting on a windowsill, or hiding near your front door? Whether you've discovered a black spider with white dots or a black and white striped spider, its unusual markings can make you wonder what species you've encountered and whether it's dangerous.
The good news is that many black and white spiders commonly found around homes are relatively harmless jumping spiders. These small spiders are known for their excellent vision, distinctive markings, and impressive ability to jump.
However, not every white and black spider belongs to the same species. Some have white spots on their abdomen, others have pale bands across their legs, and a few display a single white stripe along their backs.
Understanding these differences can help you identify the spider and determine whether professional spider pest control is necessary.
What Kind of Spider Is Black and White?
A black and white spider is often a member of the jumping spider family, Salticidae. Jumping spiders have compact bodies, relatively short legs, and large front eyes that give them excellent vision.
Unlike spiders that wait in a web for their next meal, jumping spiders actively hunt small insects. They stalk prey before making a quick, precise jump.
Several spider species display black and white markings, including:
- Zebra jumping spiders
- Bold jumping spiders
- Regal jumping spiders
- Black and yellow garden spiders
- Certain orb weaver species
The spider's body length, markings, behavior, and habitat can help narrow down its identification.
1. Zebra Jumping Spider: The Classic Black and White Striped Spider
The zebra jumping spider (Salticus scenicus) is one of the most recognizable black and white spiders.
Also called the zebra spider, this species gets its name from the contrasting black and white stripes across its body.
What Does a Zebra Spider Look Like?
A zebra jumping spider typically has a body length of approximately 5–9 millimeters, although size varies between individuals.
Its identifying characteristics include:
- A compact black body with white stripes
- Pale bands across the abdomen
- Short, sturdy legs
- Large front eyes
- Quick, jumping movements
Males and females both have striped bodies, although their proportions and markings may differ.
If you've found a small black and white striped spider on your window, exterior wall, or patio, a zebra spider is one possibility.
Where Are Zebra Spiders Commonly Found?
Zebra spiders are commonly found in temperate regions, including parts of North America and Europe.
They prefer sunny locations where they can hunt insects, including walls, tree trunks, fences, rocks, and windowsills.
Their habitat also includes gardens and urban areas where flies and other small insects are abundant.
How Do Zebra Spiders Hunt?
Zebra spiders are active daytime hunters that rely on excellent vision rather than a capture web.
They use their large front eyes to locate prey, approach slowly, and jump when they are close enough.
Like other jumping spiders, they may attach silk lines before leaping. These lines act as safety tethers if a jump does not go as planned.
Are Zebra Spiders Dangerous?
Zebra spiders are generally non-aggressive toward humans and rarely bite.
Although they possess venom to subdue small insects, their bites are not considered medically significant for most people.
A zebra spider is usually more interested in catching flies than interacting with humans.
2. Bold Jumping Spider: A Black Spider With White Dots
If you've discovered a black spider with white dots on its back, you may have encountered a bold jumping spider (Phidippus audax).
This species is common across much of North America and is frequently spotted around homes, gardens, fences, and outdoor structures.
How to Identify a Bold Jumping Spider
Bold jumping spiders have stocky, often fuzzy bodies that are usually black or dark brown.
Their most recognizable feature is a pattern of white spots on the abdomen. The markings often include one larger central spot and two smaller spots.
Additional identifying features include:
- A rounded abdomen
- White markings on the body and legs
- Large front eyes
- Iridescent green or blue mouthparts
- Short, powerful legs
Young spiders may have orange or yellowish spots that become lighter as they mature.
What About a Black Spider With One White Dot?
A black spider with white dot markings may be a bold jumping spider, but one spot alone is not enough for reliable identification.
Lighting, age, and the spider's position can make multiple markings appear to be a single white spot.
Look for the spider's body shape, front eyes, and jumping behavior before drawing a conclusion.
Do Bold Jumping Spiders Bite?
Bold jumping spiders are generally non aggressive and rarely bite unless trapped or handled.
Their venom helps them immobilize insects, but a bite is usually not medically significant for a healthy adult.
Avoid picking up an unidentified spider with your bare hands.
3. Regal Jumping Spider: A Large Black and White Spider
The regal jumping spider (Phidippus regius) is another member of the jumping spider family known for its striking appearance.
It is commonly found in the southeastern United States and nearby regions.
What Does a Regal Jumping Spider Look Like?
Regal jumping spiders are slightly larger than many other jumping spiders.
Males are commonly black with white markings, while females may appear gray, brown, tan, or orange.
Both males and females have compact bodies, large front eyes, and powerful legs.
A male regal jumping spider can resemble a bold jumping spider, so identification may require a closer look at its markings and location.
Where Do Regal Jumping Spiders Live?
Regal jumping spiders are often found on trees, fences, exterior walls, and vegetation.
Like other jumping spiders, they hunt insects during the day instead of relying on a prey-catching web.
They are generally non aggressive toward humans.
4. Black and White Orb Weaver Spiders
Not every black and white spider is a jumping spider.
Some orb weaver spiders have black, white, silver, or yellow markings that create a striped appearance.
Unlike jumping spiders, an orb weaver typically constructs a circular web to capture flying insects.
Black and Yellow Garden Spider
The black and yellow garden spider (Argiope aurantia) has a distinctive abdomen marked with black and yellow, sometimes with pale or silvery areas.
Females are much larger than males and often remain near the center of a large circular web.
These spiders are commonly found in gardens and open habitats where flying insects are plentiful.
Banded Garden Spider
The banded garden spider (Argiope trifasciata) has pale bands across its abdomen and long legs.
Its markings may appear black and white from a distance, although brown, yellow, and silver tones are often present.
Females are generally larger than males.
Are Orb Weaver Spiders Dangerous?
Most orb weaver spiders are not aggressive and rarely bite humans.
Their venom is used to subdue prey, and they generally remain near their webs rather than wandering through a house.
5. Grass Spiders With Pale Stripes
Grass spiders are another possible match when someone notices a spider with white line on back markings.
These spiders are usually brown or dark brown rather than truly black and white.
They often have pale longitudinal stripes across the front portion of their bodies.
How to Identify Grass Spiders
Grass spiders typically have:
- Long legs
- Brown bodies
- Pale stripes
- Prominent spinnerets
- Funnel-shaped webs
They are commonly found in lawns, shrubs, and low vegetation.
Grass spiders are generally non aggressive and rarely bite unless handled.
6. Cellar Spiders With Banded Legs
Cellar spiders are sometimes called daddy longlegs because of their extremely long, thin legs.
Their bodies are usually pale brown, gray, or tan rather than black and white.
However, some species have darker markings that may create a striped appearance.
Cellar spiders are commonly found indoors in basements, garages, crawl spaces, and quiet corners.
They build irregular webs and feed on small insects and other spiders.
How to Identify a Small Black and White Spider
If you've found a tiny black and white spider, several physical characteristics can help narrow down the possibilities.
Look at the Body Shape
Jumping spiders generally have compact, sturdy bodies.
Orb weavers often have larger, rounded abdomens, while grass spiders have more elongated bodies and long legs.
Examine the White Markings
A black spider with white stripes may be a zebra spider.
A black spider with white spots may be a bold jumping spider.
A small black spider with white stripe on back markings could also be another jumping spider or a grass spider with pale longitudinal bands.
Watch How the Spider Moves
Jumping spiders move in short bursts and may turn to face you.
Grass spiders typically run quickly toward shelter, while orb weavers often remain near the same web.
Check the Spider's Location
A black and white spider in house sightings may occur near sunny windows, doors, or walls.
Spiders found in basements or crawl spaces may belong to different species than those hunting on exterior walls.
Consider the Spider's Size
Body length is useful for identification, but avoid estimating size based only on leg span.
A tiny black and white spider may be a young jumping spider, while a larger spider with similar markings may belong to another species.
Are Black and White Spiders Poisonous or Venomous?
Most spiders are venomous, meaning they use venom to subdue prey.
However, venomous does not automatically mean dangerous to humans.
Many black and white spiders, including zebra jumping spiders and bold jumping spiders, rarely bite and are not considered medically significant.
The important distinction is identifying the actual species rather than judging risk by color alone.
Can a Black Spider With White Spots Be a Black Widow?
Young black widow spiders may display pale, orange, or reddish markings that differ from the appearance of mature females.
However, a black spider with white spots is not automatically a black widow.
Black widow spiders generally have smooth, rounded abdomens and longer, slender legs than jumping spiders.
A mature female black widow often has a red hourglass marking underneath her abdomen.
If you're unsure whether a spider is a black widow, avoid handling it.
Can a Brown Recluse Have White Stripes?
Brown recluse spiders are generally tan to brown and do not typically display bold black and white stripes.
A brown recluse may have a darker violin-shaped marking on the front portion of its body, but that feature alone is not enough for identification.
Unlike jumping spiders, brown recluse spiders have six eyes arranged in three pairs.
If you suspect a brown recluse or black widow is present, consider professional identification before attempting removal.
Why Are Black and White Spiders in My House?
Finding a black and white spider indoors does not necessarily indicate an infestation.
Spiders may enter homes while searching for food, shelter, or a mate.
Insects Are Attracting Spiders
Jumping spiders hunt flies, ants, and other small insects.
If insects are entering through windows or doors, spiders may follow their food sources indoors.
Openings Allow Spiders Inside
Small gaps around windows, doors, foundations, and utility lines can provide access.
Clutter Provides Hiding Places
Storage areas, cardboard boxes, and undisturbed corners can provide shelter for spiders and their prey.
Outdoor Lighting Attracts Prey
Lights near doors and windows may attract flying insects, creating hunting opportunities for spiders.
How to Get Rid of Black and White Spiders
If you've discovered a little black and white spider and would prefer it outside, removal is usually straightforward.
1. Relocate Individual Spiders
Place a clear container over the spider, slide a stiff piece of paper underneath, and release it outdoors in a sheltered location.
2. Remove Unused Webs
Vacuum corners, windowsills, and storage areas to remove webs and egg sacs.
Jumping spiders do not build webs to capture prey, but they still produce silk for shelters and egg sacs.
3. Seal Entry Points
Inspect window screens, door sweeps, and exterior gaps.
Sealing openings helps reduce access for spiders and the insects they hunt.
4. Reduce Indoor Insects
Store food properly, clean crumbs, and address other pest activity.
Reducing prey can make your home less attractive to spiders.
5. Maintain Outdoor Landscaping
Trim vegetation away from exterior walls and remove unnecessary debris near foundations.
6. Consider Professional Spider Control
If spiders repeatedly enter your home or you suspect a medically significant species, professional pest control can help.
