A wide range of animals eat spiders. Birds, lizards, frogs, toads, fish, wasps, centipedes, bats, and even other spiders all hunt spiders.
Most spider predators act opportunistically and catch spiders when they can.
The exact predators of spiders change with habitat, size, and time of day. A spider that is safe in one place may be at risk in another.
The Main Animals That Prey On Spiders
You are most likely to see common spider predators in yards, gardens, wetlands, and forests. Birds eat spiders, lizards hunt them on walls and rocks, and amphibians and centipedes take them when they pass by.
Birds As Everyday Hunters
Robins, sparrows, blackbirds, bluebirds, and wrens eat spiders. According to A-Z Animals, many common U.S. birds such as robins eat spiders often.
Birds usually spot spiders in webs, on leaves, or moving across open ground. Small birds feeding chicks can make a quick beak strike and catch spiders easily.
Lizards, Toads, And Frogs
Lizards reduce spider numbers in a big way. Geckos and some chameleons eat spiders, and lizards lower spider survival rates in controlled tests, as noted by A-Z Animals.
Toads and frogs also eat spiders when they fit in the mouth. They often wait still, then snap up prey with a fast tongue or a sudden gulp.
Other Spiders And Centipedes
Other spiders eat spiders too. Larger or more aggressive spiders catch smaller ones, or a hungry spider finds another spider close by.
Centipedes hunt spiders using their claws and venom to stop prey before eating it. They hunt in homes and leaf litter.
Wasps That Specialize In Hunting Spiders
Some wasps specialize in hunting spiders. These predators do not just eat spiders for themselves, they often use them to feed their young.
Spider Wasps And The Pompilidae Family
Spider wasps in the Pompilidae family hunt spiders for their larvae. A Pompilidae guide notes that these wasps sting and paralyze spiders, then place them in a burrow or cavity with an egg.
Adult spider wasps often feed on nectar. The spider becomes food for the developing larva.
How The Tarantula Hawk Attacks Larger Spiders
The tarantula hawk, a large spider wasp, targets tarantulas. It uses a powerful sting to paralyze the spider, then drags it to a nest and lays an egg on it.
The larva hatches and feeds on the spider.
Water And Night Predators
Some spider predators hunt near water or after dark. Fish eat spiders that fall in, and bats may grab spiders while flying at night.
Fish That Grab Spiders From The Surface
Fish such as trout and mosquitofish eat spiders that land on the water or fall in by accident. According to A-Z Animals, these fish are especially likely to take spiders in watery habitats.
This often happens near streams, ponds, and marshes. Spiders may be washed in or move across the surface film, and a fast strike from below ends the spider’s chance to escape.
How Insect-Eating Bats Catch Spiders
Insect-eating bats sometimes catch spiders as part of a mixed diet. They may pick them up in flight, especially when spiders are active at night or moving through the air on silk strands.
Night feeding gives bats a chance to take prey that many daytime hunters miss.
Why Spider Predation Matters In Nature
When you ask what eats spiders, you are looking at how the food web stays balanced. Spider predators help keep spider numbers in check, and spiders also help control insects.
How Habitat Changes Which Predators Show Up
Where you live changes which predators of spiders are most likely to appear. Wet areas bring fish, frogs, and toads into the picture.
Gardens and forests may have more birds, lizards, and centipedes. Spider webs, leaf litter, rocks, and water edges all create different hunting zones.
A spider near water faces different threats than one hiding in bark or grass.
Why Spiders Are Both Hunters And Prey
Spiders hunt insects throughout their lives. Many animals hunt spiders as well.
This makes spiders both predator and prey. Their place in the food web supports birds, reptiles, amphibians, fish, and insects that hunt spiders.
Spiders also keep pest insects under control. Their role works in more than one direction.
