Spiders are fascinating creatures that are found in almost every corner of the world. They are known for their predatory behavior and their ability to spin webs. However, despite their impressive abilities, spiders have natural predators that play an important role in controlling their population. In this article, we will explore some of the natural predators that prey on spiders.


Birds are one of the most common predators of spiders. Many bird species, such as the American robin and the house wren, feed on spiders as part of their diet. Birds have excellent eyesight and can easily spot spiders from a distance. They also have sharp beaks that allow them to pick up spiders and eat them.

Certain bird species have even evolved to specialize in hunting spiders. The black-backed woodpecker, for example, preys almost exclusively on wood-boring spiders. This specialization allows birds to effectively control spider populations in their habitats.

Other Arthropods

Spiders are not immune to predation by other arthropods. In fact, many species of insects and other arthropods feed on spiders as part of their diet. For example, praying mantises are known to prey on spiders, as are many species of beetles.

One particular group of arthropods that preys heavily on spiders is the assassin bugs. These bugs use their long proboscis to inject enzymes into the spider’s body, which liquefy its internal organs. The assassin bug then sucks out the resulting fluid, leaving behind an empty shell.


While birds and other arthropods are common predators of spiders, certain mammals also prey on spiders. One such mammal is the shrew. Shrews are small, mouse-like creatures that live in a variety of habitats around the world. They are voracious predators and will eat almost anything they can catch, including spiders.

In addition to shrews, certain species of bats also feed on spiders. These bats have evolved to be able to detect and capture spiders in flight, often using echolocation to locate their prey.


Spiders are also preyed upon by certain reptiles, such as lizards and snakes. One such lizard is the green anole, which is native to the southern United States. Green anoles are known to eat spiders, as well as other insects and small arthropods.

Snakes, on the other hand, are less likely to prey on spiders. However, certain species of snakes, such as the brown snake and the ringneck snake, have been known to eat spiders on occasion.


In conclusion, spiders may be impressive predators, but they are not immune to predation themselves. Birds, other arthropods, mammals, reptiles, and even some amphibians all prey on spiders as part of their diet. While these natural predators may help control spider populations in certain habitats, they also play an important role in maintaining the balance of ecosystems around the world. As fascinating creatures in their own right, spiders continue to captivate us with their unique abilities and interactions with other species in their environment.
