Black Spiders With White Spots In Texas: Identification And Bite Risks

If you’ve spotted a creepy black spider decorated with bright white spots in Texas, you may be wondering what it is and if it’s dangerous. This guide covers how to identify black and white spiders in Texas, any venom risks they pose, and how to safely avoid them.

If you’re short on time, here’s the key facts: The most common black spider with white spots in Texas is the spitting spider. While not aggressive, they can bite in self defense. Their venom is mildly toxic, similar to a bee sting. Leave spitting spiders alone and be cautious of webs in corners or furniture.

Appearance and Behaviors

Black spiders with white spots in Texas are fascinating creatures with unique appearances and behaviors. Let’s explore two specific types of these spiders: spitting spiders and other black and white spider species.

Spitting Spiders

Spitting spiders, also known as Scytodidae, are a type of black spider with white spots commonly found in Texas. These spiders have a distinct physical appearance, with a jet-black body covered in small white markings. Their abdomen is usually round and compact, and they have long, spindly legs.

What sets spitting spiders apart from other spiders is their remarkable hunting technique. Instead of relying solely on webs to catch prey, they use a unique method known as “spitting.” These spiders possess venom glands in their chelicerae, which they can aim and project with great accuracy.

They shoot a sticky, silk-like substance mixed with venom at their prey from a distance of up to several centimeters. This immobilizes the prey, allowing the spiders to approach and feed on it.

Despite their intimidating method of hunting, spitting spiders are generally not harmful to humans. Their venom is primarily used to subdue their prey and is not considered dangerous to humans. However, if you encounter a spitting spider, it is best to avoid handling or provoking it to prevent any potential bites.

Other Black and White Spider Species

In addition to spitting spiders, there are other black spiders with white spots that can be found in Texas. Some of these species include the daring jumping spider (Phidippus audax) and the black and white garden spider (Argiope aurantia).

The daring jumping spider is a small and agile spider known for its impressive jumping abilities. With a black body adorned with white spots, it can often be found lurking in gardens and outdoor spaces.

While their appearance may be intimidating, daring jumping spiders are harmless to humans and are considered beneficial as they help control insect populations.

The black and white garden spider, on the other hand, is larger in size and has a striking pattern of black and white markings on its abdomen. These spiders are skilled weavers and construct intricate orb-shaped webs to catch their prey.

While their bite is generally harmless to humans, it is advised to avoid disturbing their webs to prevent any potential bites.

It is important to note that while black spiders with white spots in Texas may have unique appearances and behaviors, they are generally not a cause for concern. However, if you have any concerns about a spider bite or encounter a spider that you are unsure about, it is always best to seek advice from a local pest control professional or an entomologist.

Habitats and Distribution in Texas

Black spiders with white spots can be found in various habitats throughout Texas. Their distribution is influenced by factors such as climate, vegetation, and availability of prey. Here are the two main habitats where these spiders can be commonly found:


Outdoors, black spiders with white spots can be found in a wide range of locations. They are often found in gardens, parks, forests, and other natural areas. These spiders prefer areas with vegetation and hiding spots, such as shrubs, tall grass, and leaf litter.

They are known to build their webs in trees, bushes, and other structures, where they can easily catch their prey.

It is important to note that not all black spiders with white spots are venomous. In fact, most of them are harmless and play a beneficial role in controlling the population of insects and pests in their surroundings.

However, it is always a good idea to be cautious and avoid disturbing their webs or getting too close to them.


Black spiders with white spots can also find their way into indoor spaces in Texas. They can enter homes, garages, sheds, and other structures through small openings or gaps. Common indoor hiding spots for these spiders include basements, attics, closets, and corners of rooms.

If you come across a black spider with white spots indoors, it is important to take precautions and avoid direct contact. While most spiders found indoors are not harmful, it is still wise to be cautious and not handle them without proper knowledge or experience.

If you are unsure about the species or potential risks, it is recommended to contact a professional pest control service for assistance.

Bite Symptoms and Spider Venom Toxicity

When it comes to black spiders with white spots in Texas, it is important to be aware of the potential bite symptoms and the toxicity of their venom. While most spider bites are harmless and cause only mild reactions, some individuals may experience more severe symptoms that require medical attention.

Mild Reactions to Venom

In general, the bites of black spiders with white spots in Texas result in mild reactions. Common symptoms include localized pain, redness, and swelling at the site of the bite. It is not uncommon for individuals to experience itching or a rash in the affected area as well.

These mild reactions typically subside within a few days with minimal intervention.

Did you know? The venom of black spiders with white spots in Texas is not considered highly toxic to humans. While their bites can be uncomfortable, they are generally not life-threatening.

However, it is important to note that individual reactions to spider venom can vary. Some people may have a higher sensitivity to the venom, leading to more pronounced symptoms. If you experience severe pain, difficulty breathing, dizziness, or any other concerning symptoms after a spider bite, it is crucial to seek medical attention immediately.

Seeking Medical Care

If you are unsure about the severity of your symptoms or if you are experiencing any concerning symptoms after being bitten by a black spider with white spots in Texas, it is best to seek medical care.

A healthcare professional will be able to evaluate your symptoms and determine the appropriate course of treatment.

In some cases, medical intervention may be necessary to alleviate pain, reduce swelling, and prevent the development of secondary infections. Additionally, if you are unsure whether the spider that bit you was a black spider with white spots or if you have any doubts about its identification, a healthcare professional can provide guidance and reassurance.

Remember: When it comes to spider bites, it is always better to err on the side of caution and seek medical attention if you are unsure or experiencing severe symptoms.

Spider Safety and Bite Prevention

When it comes to dealing with black spiders with white spots in Texas, it’s important to prioritize safety and take steps to prevent spider bites. By following some simple guidelines, you can reduce the risk of encountering these spiders and minimize the chances of getting bitten.

Here are some effective strategies to ensure spider safety:

Cleaning and Reducing Clutter

Keeping your living space clean and clutter-free is an essential step in spider bite prevention. Spiders are attracted to dark and undisturbed areas where they can build their webs and hide. By regularly cleaning and decluttering your home, you eliminate potential hiding spots for spiders and make it harder for them to establish a presence.

Vacuuming regularly, dusting corners, and removing any unnecessary clutter can go a long way in reducing the chances of encountering these spiders.

Sealing Points of Entry

Another important measure to prevent spider bites is to seal any possible points of entry into your home. Spiders can enter through small cracks, gaps, and openings, so it’s crucial to inspect your home for any potential entry points and seal them off.

This includes sealing gaps around windows and doors, repairing damaged screens, and filling in cracks in walls or foundation. By taking these preventive steps, you create a barrier that makes it difficult for spiders to enter your living space.

Using Protective Gear

If you’re planning to spend time in areas where these black spiders with white spots are commonly found, it’s advisable to use protective gear. Wearing long-sleeved shirts, long pants, and closed-toe shoes can provide a physical barrier between you and the spiders, reducing the risk of bites.

Additionally, using gloves and hats can offer extra protection, especially if you’re working in areas where spiders may be present. Remember to shake out any clothing or shoes before wearing them, as spiders may seek refuge in these items.

By following these safety measures and taking proactive steps, you can significantly reduce the risk of encountering black spiders with white spots in Texas and minimize the chances of getting bitten.

Remember, prevention is key when it comes to spider bites, so it’s essential to stay vigilant and prioritize your safety.


Black spiders with white spots like the spitting spider are generally timid and reclusive. While their venom can cause mild irritation, they are not considered medically significant. With proper identification and bite prevention tactics, Texans can coexist safely with these intriguing arachnids.
