As spider enthusiasts, we are always searching for new and exciting ways to learn about our arachnid friends. However, one particular spider that may send shivers down your spine is the black widow. While their venomous bite is well-known, identifying their eggs can be just as important for safety reasons. But what do black widow spider eggs look like? In this guide, we will explore the physical characteristics of black widow spider eggs and provide step-by-step instructions on how to identify them. So, grab your magnifying glass and let’s get started!
Physical Characteristics of Black Widow Spider Eggs
When it comes to identifying black widow spider eggs, it’s important to understand their physical characteristics. Black widow spiders are well-known for their unique physical traits, which allow them to adapt to their environment and capture prey. However, their eggs have their own distinct features that set them apart from other spider eggs. By understanding the color, shape, size, texture, and location of black widow spider eggs, you can learn to differentiate them from other spider eggs. To better understand the physical characteristics of black widow spider eggs, take a look at our guide to understanding the physical characteristics of these fascinating creatures, including their sensory capabilities, silk uses, and body types in comparison to other spiders.
Color
Color is one of the key features to identify black widow spider eggs. The egg sacs are usually white or yellow in color, with small brown or black spots on the surface. However, it is important to note that the egg sac’s color may vary depending on the female spider’s diet and habitat. Some may appear to be beige or tan.
Interestingly, the color of the egg sacs can also change during the incubation period. Initially, they appear white but will eventually turn yellow and then brown as the eggs inside develop and near hatching.
It is worth mentioning that the color of the egg sacs is not always a reliable indicator of the presence of black widow spider eggs. Some other spider species, such as the common house spider, have similar-looking egg sacs. It is vital to consider and compare the eggs’ other physical characteristics to differentiate them from other spiders.

Shape and Size
Shape and Size: Black widow spider eggs are typically round or oval-shaped, with a slightly flattened appearance. They are roughly the size of a pinhead, about 1mm in diameter, but can vary depending on the age of the egg sac. A mature egg sac can contain up to 900 eggs. It’s important to note that the exact shape and size can differ between species of black widow spiders, so it’s important to consider other physical characteristics when identifying the eggs. To learn more about the differences between black widow spider species, check out our article on size differences among black widows.
To further illustrate the differences, here’s a table comparing the common physical characteristics of three black widow spider species:
| Species | Shape | Size | Color |
|---|---|---|---|
| Latrodectus mactans | Round | 1mm in diameter | Glossy black |
| Latrodectus hesperus | Oval | 1-2mm in diameter | Shiny black |
| Latrodectus variolus | Oval | 1-1.5mm in diameter | Dull black or brown |
As you can see from the table, while all three species have similar egg shapes, their sizes and colors can differ. It’s important to not rely on just one physical characteristic when trying to identify black widow spider eggs.

Texture
Black Widow Spider eggs have a unique texture that distinguishes them from other spider species. The sacs have a papery and silk-like texture that can be felt with the fingers. According to the sensory capabilities of Black Widow spiders, the mother spider creates the egg sacs with a combination of her silk and her bodily secretions. This combination ensures that the eggs are protected and stay in place until they hatch. The texture also provides a secure and warm environment for the eggs to develop.
When identifying Black Widow Spider eggs, it’s important to consider the texture of the sacs because it is a key characteristic that differentiates them from other spider egg sacs. The silk-like texture is similar to that of other spider egg sacs, but the papery texture is unique to Black Widow Spider egg sacs. The papery texture is due to the thin walls of the sacs, which make the eggs and spiderlings vulnerable to environmental factors such as strong winds and predators.
To sum up, identifying the texture of the egg sacs is an essential step in the process of identifying Black Widow Spider eggs. The unique combination of silk-like and papery texture of the sacs is an adaptation that helps protect the eggs and promote their development. By feeling the texture of the sacs with your fingers, you can identify Black Widow Spider eggs and distinguish them from other spider species.
Location
Location is a crucial aspect of identifying black widow spider eggs. These spiders have adapted to various environments and are found in different locations. The best way to locate the eggs is to know where to look. Black widow spiders tend to choose hidden and sheltered places to build their nests, which may be indoors or outdoors.
Indoors: Black widow spider eggs are often found indoors in dark, cluttered, and secluded corners. Some common indoor locations where they build nests include attics, basements, closets, and garages.
Outdoors: Black widow spiders also build nests in various outdoor locations. Some common outdoor locations where they build nests include woodpiles, garden sheds, debris, and cluttered areas. They also prefer to build in areas protected from the elements and where they can easily catch prey, such as near porch lights, doorways, and windows.
To differentiate black widow spider eggs from other spider species, it is important to know where they are commonly found. It’s worth noting that black widows are not found in all parts of the world, so it’s important to do research on your local area.
If you’re having trouble locating black widow spider eggs, it may be helpful to consult a professional exterminator or spider expert who can help identify their location and take the necessary steps to eliminate them.
Pro tip: If you’re outdoors, wear protective gear such as gloves and sturdy shoes, especially when handling outdoor items such as woodpiles where black widow spider eggs may be hidden.

How to Identify Black Widow Spider Eggs
Curiosity about the black widow spider and its eggs is common among spider enthusiasts. However, identifying black widow spider eggs can be a perplexing task, but fear not, as we have got you covered! In this section, we will discuss the step-by-step process of identifying black widow spider eggs with the help of some physical characteristics that make them unique. By following these steps, you can easily detect black widow spider eggs wherever they may be hiding. So, let’s dive in and discover the art of identifying black widow spider eggs.
Step 1: Look for Egg Sacs
The first step in identifying black widow spider eggs is to look for their egg sacs. These sacs are usually easy to spot as they are large and quite distinct in appearance. Black widow spiders typically construct their egg sacs using a combination of silk and debris such as leaves and twigs.
To find these egg sacs, you should start by looking in areas where black widow spiders are most likely to congregate. This might include dark corners, crevices, and other secluded spaces. Check places such as your garage, basement, or attic, as these are common areas where black widow spiders like to hide.
Once you’ve identified a potential location, use a flashlight to scan the area for egg sacs. Look for white, round, or oblong shapes that are approximately the size of a marble. These sacs are typically attached to a surface using a thin strand of silk.
Pro-tip: Black widow spider egg sacs can sometimes be mistaken for other types of spider sacs. However, black widow spider egg sacs are larger and more distinctive than other types of spider sacs. So, be sure to look for the specific characteristics of a black widow spider egg sac as described in the following steps.
If you find an egg sac, proceed to the next steps to determine if it is indeed a black widow spider egg sac.
Step 2: Observe Color
When it comes to identifying black widow spider eggs, color can be an important factor. The eggs of these spiders have a distinct color that can help you identify them more easily.
Color of Black Widow Spider Eggs
Black widow spider eggs are typically white or cream in color. However, they can sometimes be yellowish or brownish as well. It’s important to note that the color of the eggs may change as they mature.
To make it clear and easy to read, here is a table that shows the different colors that black widow spider eggs may have:
| Color | Description |
|---|---|
| White | The most common color for black widow spider eggs. |
| Cream | Similar to white, but with a slightly darker hue. |
| Yellowish | A bright yellow color that may indicate the eggs are getting close to hatching. |
| Brownish | A darker color that could indicate the eggs are older. |
It’s important to note that the color of black widow spider eggs may be affected by lighting conditions, as well as the conditions in which the eggs are stored. If you’re unsure about the color of the eggs you’ve found, it’s always a good idea to look at other physical characteristics to confirm your identification.
Step 3: Examine Shape and Size
When it comes to identifying black widow spider eggs, shape and size is another important factor to consider. The egg sacs of a black widow spider are typically spherical in shape, with a slightly pointed end. The size of the egg sac can vary depending on the species of the spider, but they are typically around 10 to 13mm in diameter. However, it is important to note that size can vary and may not always be a reliable indicator of identifying black widow spider eggs.
One way to check the shape and size of spider eggs is to carefully observe them with a magnifying glass or a camera with macro mode. This will help you to see the sac’s details and helps with accurate identification. Ensure that you do not touch them, as black widow spider eggs can be incredibly fragile and can easily break.
Another thing to note is the surface of the egg sac. Black widow spider eggs have a smooth and almost shiny surface. If you find an egg sac with a rough surface, it is likely not from a black widow spider.
It is worth noting that not all spider egg sacs are easy to identify, and it is best to consult with an expert if you are uncertain. Additionally, it is imperative to remain cautious and avoid touching or disturbing spider eggs, as it could lead to a dangerous encounter.
Step 4: Check for Texture
When identifying black widow spider eggs, it is crucial to check for texture. The texture of the egg sac can provide valuable clues to help identify if it’s a black widow spider egg or not. Here are a few characteristics of the texture to look for:
- Smoothness: Black widow spider eggs tend to have a smooth texture, lacking any bumps or ridges that may be present on the egg sacs of other spider species.
- Sturdiness: The egg sacs of black widow spiders are known to have a durable and strong texture that can withstand significant pressure.
- Stickiness: Black widow spider eggs are sticky to the touch due to the silk strands that hold the egg sac together. When observing an egg sac, be mindful of any stickiness, which can indicate the presence of a black widow spider egg.
It is essential to note that some non-poisonous spider eggs may also feel sticky, but the texture is usually not as sturdy as that of black widow spider eggs. It’s best to consider all the characteristics as a whole when attempting to identify black widow spider eggs.
Remember that black widow spider eggs should be approached with care. If you are not confident in your ability to identify the eggs, it’s best to call a pest control specialist for assistance.
Step 5: Note the Location
When identifying Black Widow spider eggs, noting the location of the egg sac is another important step. These spiders typically build their egg sacs in secluded areas where their offspring can hatch undisturbed. Keep an eye out for corners of your home or garage, dense vegetation, and other areas that offer hidden, sheltered spots.
Here are some more specific locations to look for Black Widow spider eggs:
- Outdoors: Black Widow spiders prefer to build their egg sacs in areas away from human activity, but if you live in an area with a high spider population, they may sometimes be found closer to your home or other buildings. Look for egg sacs in the corners of sheds, garages, barns, and other structures.
- Indoors: If you suspect that there may be Black Widow spider eggs in your home, take a look in dark, cluttered areas where spiders may be hiding. These include basements, attics, closets, and storage rooms. Be sure to also check out areas where you store clutter or items that haven’t been disturbed in a while since spiders may be more likely to lay eggs in these spots.
- In Your Yard: Black Widow spiders can be found in a variety of outdoor locations, so it’s important to be cautious when exploring your yard. Look for egg sacs in piles of firewood, under outdoor furniture, in nooks and crannies of your railing or deck, and in dense bushes or shrubs.
Remember that Black Widow spiders are poisonous and should be approached with caution. If you come across an egg sac, it’s best to call a professional exterminator or use caution when removing it yourself. Avoid touching the sac directly and wear gloves and long sleeves to protect yourself.
