8 Surprising Facts About Spiders and Colors

Spiders and colors might seem like an odd pairing, but surprisingly, there’s a lot to learn from the relationship between these two topics. From the colors spiders hate to the ones they love, and the scientific explanations behind how they see, this article seeks to provide readers with comprehensive knowledge about spiders and colors.

Colors Spiders Hate

Have you ever wondered if you could repel spiders naturally? If so, light blue might be a color to consider.

Studies show that spiders are not fans of the light blue hue. Repelling spiders can also be achieved by using colors that repel wasps.

Spiders will avoid light blue for the same reason: the color resembles the sky and natural predators that spiders want to avoid.

Colors Spiders Love

On the flip side, spiders are attracted to green colors. This is because spiders are sensitive to green wavelengths, and the color green resembles nature, where spiders can find their prey.

Therefore, you might want to avoid wearing green clothing or planting green flowers. On the other hand, if you want to attract spiders, adding a touch of green to your environment might do the trick.

Colors Bugs See

If you’re trying to avoid attracting mosquitoes, it’s important to know which colors catch their attention. Mosquitoes are most attracted to dark colors, such as black, dark blue, and red.

Pastels, on the other hand, are less attractive to mosquitoes. So, if you’re going to a mosquito-infested area, it’s best to wear light-colored clothing.

How Spiders See

Dichromatic Vision

Most spiders have dichromatic vision, which means they can only see two colors: green and ultraviolet light. This kind of vision explains why spiders are sensitive to the color green and attracted to it.

Eyes of Spiders

Spiders’ eyes come in different forms, shapes, and sizes. Most spiders have primary eyes, which are larger than the secondary eyes.

The primary eyes are also responsible for producing high-resolution images. Secondary eyes are smaller and used to detect motion.

Some spiders have ocelli, which are eye-like structures found on the top of their heads. Ocelli don’t produce high-resolution images but work in combination with spider’s setae.

Setas are touch sensors that help spiders navigate their surroundings.

Spider Sight Limitations

Despite varying eye structures and complex nervous systems, spider’s eyes have significant limitations. Compared to humans, spiders have very poor eyesight.

Spiders are sensitive to brightness, making them vulnerable to polarized lighting. Some spiders have good eyesight, and they can recognize their prey from a distance, even in low light conditions.


To sum it all up, understanding the colors spiders love and hate can help you repel or attract them in your environment. The same applies to other insects, such as mosquitoes.

Studying spider’s eyes shows their limited vision, which increases their susceptibility to polarized lighting. Overall, the more you know about spiders and colors, the better equipped you will be to make informed decisions about your environment.

Using Blue to Repel Spiders

Are you looking for an aesthetic way to repel spiders from your home? Painting the ceiling of your porch blue could do the trick.

Spiders, just like other insects, view blue colored structures as the sky and will avoid them. If you’re planning to repaint your house, painting the shutters, window trim, or doors in blue might also help repel spiders.

Aside from painting your home blue, you can use natural spider repellents. Some spiders hate the scent of certain essential oils like lemon oil or peppermint oil.

Chestnuts, lima oil, or Mighty Mints Insect and Pest Control are other natural repellents that can keep spiders at bay. Prevention is also key to keeping spiders away.

Assessing your environment, particularly determining areas with high spider activity, is essential. If you live in an area with high humidity or near moist soil, it’s more likely for you to have spider infestations.

Keeping your home clean and organizing outside clutter is also pertinent to spider-proofing your home. Filling holes and cracks, securing food, and controlling vegetation around your home can also prevent spiders from entering.

When it comes to vegetation, trimming bushes and keeping them away from your home’s foundation should be a priority. Finally, if you’ve already had a spider infestation before, reaching out to pest control services could also ensure that it won’t happen again.

Harmless Household Spiders

Despite being creepy-crawlies, most household spiders are generally harmless to humans. Learning about the spider species in your home environment can help you determine which ones are harmless.

Here are some common spider species that pose no danger to humans:

Wolf spiders – These spiders are hairy and are sometimes mistaken for tarantulas. They’re agile and fast runners but usually avoid humans.

Jumping spiders – These spiders are known for their unique jumping ability. They’re small, harmless, and often have distinct eye patterns.

Cobweb spiders – These spiders create cobweb-like structures but are not aggressive. Their bite is harmless and usually doesn’t affect humans.

Parson spiders – These spiders have uniquely patterned abdomens and are also harmless to humans. Grass spiders – These spiders are brown and have noticeable stripes on their legs.

They’re usually seen in tall grass and are often harmless. It’s important to note that keeping spiders around your home could also be beneficial.

Spiders are natural pest controllers and can keep the insect population down. Checking to ensure the spider population in your home is not rapidly increasing is important.

It’s necessary to identify and differentiate between non-harmful and risky spider species. Here are some venomous and potentially poisonous spider species:

Black Widow spiders – These spiders have a characteristic hourglass shape and can be extremely harmful to humans.

Brown Recluse spiders – These spiders are primarily found in South and Central U.S. regions and have a unique violin figure on their torso. Hobo spiders – These spiders envision living space in dark and undisturbed areas.

They’re commonly found in the Pacific Northwest region. If you’ve discovered such spiders in your home, it’s advised not to interact with them and to contact pest control services.

In summary, being informed about the spider species in your environment could protect you from potential harm. Recognizing harmless spiders like wolf spiders, jumping spiders, cobweb spiders, parson spiders, or grass spiders could allow you to keep them around and naturally control pests.

Additionally, taking preventive measures like keeping the house tidy and well-lit can prevent spider infestations.

Miscellaneous Spider Information

Most people have a natural fear of spiders, which has led to numerous myths and rumors about their behavior. Here are some miscellaneous spider-related facts that could help alleviate some of the misinformed beliefs.

Spider Infestation

If you’ve seen an increased spider presence around your home, it’s possible you have a spider infestation. Assessing your home, both inside and outside, to find areas where spiders can enter is crucial to spider-proofing your home.

Spiders can enter through the smallest cracks; therefore, checking and sealing these openings would prevent spiders from making their way inside. Another solution is to replace old window screens, as spiders can sneak through the smallest of holes.

Spraying spider repellent in areas where you’ve seen spider activity can also help prevent more spiders from entering. Finally, if you have a severe spider infestation, seeking professional help might be necessary.

Why Spiders Are Considered Bad

Spiders have a negative reputation, mainly because the reluctance to interact with them stemmed from the fear of potential harm. People often believe all spiders are venomous and capable of causing significant harm, which isn’t true.

In reality, most spiders are harmless to humans and do more good than bad. Spiders play an important role in our ecosystem as they naturally control the population of insects in and around the house.

Arachnids, particularly spiders, can eat up to 400 million tons of insects annually, limiting the effect the insect population has on agriculture. On the other hand, it’s necessary to understand that some spider species can be dangerous.

Black Widow spiders and Brown Recluse spiders pose a significant threat to humans and should be treated with caution. The important thing to remember is to differentiate between harmless and dangerous spiders and take preventive measures to keep the dangerous ones away.


If you’re unsure about the spider species in your home or how to handle a spider infestation, it’s vital to consult expert sources. Research on spider behavior and pest control is continuously conducted worldwide.

Collaborating with various sources and experts like entomologists, pest control professionals, and researchers can provide a clearer understanding of spider biology and behavior. Reading reputable and reliable sources on spider-related topics such as identification, biology, and pest control can improve your knowledge and understanding of spiders.

Conducting your research on spider-related topics could ensure that you obtain appropriate information and recommendations, regardless of your spider encounter.


Spiders play an essential role in our ecosystem by controlling the population of harmful insects, making them beneficial livestock. Identifying harmless and dangerous spider species is imperative to keep both safe and prevent infestation.

Conducting extensive research and consulting experts could also help manage spider infestations and take preventive measures to keep spiders at bay. In conclusion, the diverse nature of spider’s behavior, vision, and environment necessitates extensive education on the spider species and preventive measures.

Understanding the colors spiders love and hate could also help repel them from your environment. Several natural repellents such as peppermint and lemon oil can also fulfill your spider-free desires.

Differentiating between harmful and harmless spiders is an important safety measure. Identifying potentially venomous spiders is critical for safeguarding human health.

Finally, continuing to grow your knowledge and expertise with reputable sources will give you a better chance of preventing and managing spider infestations.
