Spiders, with their intricate webs and remarkable silk-spinning abilities, have fascinated and terrified humans for centuries. These arachnids are often subject to numerous myths and misconceptions that exaggerate their danger or underestimate their importance in ecosystems.
In this article, we will debunk some of the most common myths about spiders and provide the scientific facts that dispel these misconceptions.

15 Myths About Spiders
Here are the 15 most common myths about spiders:
Myth 1: All Spiders Are Venomous and Dangerous
One of the most widespread myths is that all spiders are venomous and pose a significant threat to humans.
In reality, the vast majority of spider species are not dangerous to humans. While nearly all spiders produce venom to immobilize their prey, most are not harmful to humans due to their fangs being too small or their venom being too weak to pose any danger.
In fact, there are only a few species, such as the black widow and brown recluse, whose venom can potentially harm humans.
However, even these species rarely bite and are not typically fatal. Most spiders prefer to avoid humans and only bite in self-defense when they feel threatened.
Myth 2: Spiders Are Insects
Contrary to the myth that spiders are insects, they belong to a separate class of arthropods called Arachnida.
While both insects and arachnids are arthropods, they have distinct differences in their body structures and characteristics.
Spiders have two main body parts, the cephalothorax and abdomen, and eight legs. In contrast, insects have three main body parts (head, thorax, and abdomen) and six legs. Understanding these differences is essential for proper classification and scientific study.
Myth 3: Spiders Are All Web Spinners
The image of a spider spinning an intricate web is often associated with all spider species.
However, this myth overlooks the diversity of spider behaviors and habitats. While many spiders are known for their web-building abilities, others are hunters that actively seek out their prey. Wolf spiders, for example, chase down their victims on the ground.
Jumping spiders stalk and pounce on their prey, while trapdoor spiders construct burrows with hinged lids to ambush passing insects. The web-spinning behavior is just one of many strategies adopted by different spider species for hunting and survival.
Myth 4: All Spiders Are Dirty and Disease Carriers
Another common myth associates spiders with dirt and disease. In reality, spiders are quite clean creatures. They meticulously groom their bodies and legs to keep them free from dust and debris.
Furthermore, spiders play a vital role in ecosystems by controlling insect populations, including disease-carrying insects like mosquitoes.
Instead of being disease carriers, spiders contribute to overall pest control, reducing the risks associated with disease transmission by insects.
Myth 5: All Spiders Are Large and Scary
The myth that all spiders are large and frightening couldn’t be farther from the truth.
While some spider species can be quite large and imposing, many are tiny and inconspicuous. The world of spiders offers a wide range of sizes and colors.
From the minuscule feather-legged lace weaver to the massive Goliath bird-eating spider, the diversity among spiders highlights their unique adaptations and ecological niches.
Myth 6: Daddy Longlegs Are the Most Venomous Spiders
A common myth is that daddy longlegs (harvestmen) are the most venomous spiders in the world.
In reality, daddy longlegs are not spiders; they belong to the order Opiliones, which is distinct from true spiders.
Moreover, they do produce venom but lack the fangs to deliver it, making them harmless to humans. True spiders, such as the brown recluse or funnel-weaving spiders, possess more potent venom and can bite humans, although such occurrences are rare.
Myth 7: Spiders Lay Eggs Under Human Skin
An urban legend often involves spiders laying their eggs under a person’s skin.
This myth, which leads to fear and sensationalism, is entirely untrue. Spiders lay their eggs in silk sacs, usually attached to a surface or hidden within webs. They would never lay eggs under the skin of a living being.
Skin conditions or sensations may be attributed to various factors, but spider egg-laying is not one of them.
Myth 8: Tarantulas Are Highly Aggressive and Will Attack Humans
Tarantulas, known for their impressive size and hairy appearance, are often misunderstood as highly aggressive and dangerous to humans.
The truth is that most tarantula species are quite docile and rarely pose a threat. Their first instinct is to flee rather than attack. When cornered, they may use their urticating hairs as a defense mechanism or bite if provoked.
However, their bites are typically not medically significant and are far less dangerous than the bites of smaller, medically important species like the black widow or brown recluse.
Myth 9: Daddy Longlegs Are Deadly But Lack Fangs
Another myth related to daddy longlegs is that they are highly venomous, but their fangs are too short to bite humans.
As mentioned earlier, daddy longlegs belong to the order Opiliones and not true spiders.
They do produce venom but lack venomous fangs entirely. These arachnids are entirely harmless to humans and pose no threat of envenomation.
Myth 10: Spiders Can Lay Eggs in Your Ears or Mouth While You Sleep
The fear of spiders crawling into orifices like ears or mouths while sleeping is a common phobia that leads to myths.
In reality, such occurrences are extremely rare, and no evidence supports the idea that spiders seek human orifices for nesting.
Spiders generally avoid humans and find other suitable hiding places. While the concept may be a source of anxiety for some, it is important to recognize that such incidents are exceptions rather than the rule.
Myth 11: Spiders Are Attracted to People with Arachnophobia
Contrary to the belief that spiders are drawn to individuals with arachnophobia, there is no scientific evidence supporting this claim. Spiders do not possess the ability to detect or respond to human phobias.
Arachnophobia is a common fear of spiders, and individuals with this phobia may experience heightened anxiety or fear when encountering spiders. However, the spiders themselves are not attracted to specific individuals based on their phobias.
Myth 12: All Spider Webs Are the Same
The misconception that all spider webs are identical overlooks the incredible diversity in web designs among different spider species. Spiders create webs for various purposes, including capturing prey, shelter, or reproduction.
Orb-weaving spiders construct intricate, circular webs to catch flying insects, while funnel-weaving spiders build funnel-shaped webs on the ground for ambushing prey. Understanding the diversity in web structures enhances our appreciation for the complexity of spider behavior.
Myth 13: Spiders Can Only Walk Upside Down
The idea that spiders can only walk upside down is a misperception. Spiders are capable of walking in any orientation, including upside down, thanks to their specialized leg muscles and adhesive setae.
Spiders use a combination of leg movements and adhesive hairs on their feet to navigate various surfaces. This adaptability allows them to move effortlessly on walls, ceilings, and other surfaces without being limited to a specific orientation.
Myth 14: Daddy Longlegs Can Detach Their Legs for Defense
A common myth suggests that daddy longlegs can detach their legs as a defense mechanism. In reality, daddy longlegs do not have the ability to voluntarily detach their legs.
While they may shed their legs as a response to a threat or disturbance, this process is called autotomy and is not a deliberate defensive action. The shed leg may continue to twitch, creating the illusion that it is still moving.
Myth 15: Spiders Are Insects, and Insects Are Spiders
Confusion persists regarding the distinction between spiders and insects, leading to the myth that these terms are interchangeable. In reality, spiders belong to the class Arachnida, while insects belong to the class Insecta.
Understanding the anatomical differences, such as the number of body parts and legs, is crucial for accurate classification. Spiders and insects represent distinct groups within the broader category of arthropods, each with its own unique characteristics.
