What Eats Ants? Natural Predators That Help Control Ant Populations

Ants may be tiny, but they can quickly become a big nuisance for homeowners. While chemical treatments are typically the go-to solution, nature has its way of keeping ant populations in check. 

Many creatures feast on ants from mammals and birds to reptiles and even other insects as part of their regular diet. Knowing more about these natural ant predators provides eco-friendly alternatives for managing ant problems. 

This article explores the fascinating world of ant-eating animals and how they contribute to natural pest control.

Mammals That Eat Ants

Several mammal species have evolved to become specialized ant predators. These animals have developed unique adaptations to efficiently hunt and consume ants. Let’s look closely at some of the most notable ant-eating mammals.

Anteater

As their name suggests, anteaters are‌ the most well-known ant predators. Native to Central and South America, these medium-sized mammals have a diet of almost entirely ants and termites. 

Anteaters have several specialized features that make them expert ant hunters. They have long snouts that allow them to reach deep into ant nests and sticky tongues up to 2 feet long for scooping up many ants. 

Their sharp claws are perfect for digging into ant colonies. Several species of anteaters, ranging in size and distribution, but they all share a myrmecophagous diet—subsisting primarily on ants and termites.

Aardvark

Though they may resemble anteaters, aardvarks are‌ distant relatives. Native to the African continent, aardvarks have independently evolved similar features to anteaters through convergent evolution. 

Like their South American cousins, aardvarks have a long, sticky tongue for catching ants, strong claws for digging into ant and termite nests, and a long snout for looking into ant colonies. Interestingly, aardvarks are more closely related to elephants and manatees than anteaters.

Pangolin

Pangolins are unique mammals covered in hard, protective scales. Found in parts of Africa and Southern Asia, pangolins have a diet that consists mostly of ants and termites. 

Their specialized features include sharp claws for digging and climbing, a long, sticky tongue for capturing insects, and hard scales that protect them from larger predators. Some pangolin species are excellent climbers, using their powerful tails and claws to strip bark from trees in search of insects.

Birds

Many bird species have adapted to feed on ants and other small insects. Some birds even do a behavior called anting. They rub dead ants on their bodies to scare away predators and fight fungus and disease with the ants’ collected plant materials. 

These avian predators usually have long, pointed beaks that help them catch insects quickly and accurately. Here are some notable ant-eating birds:

Antbirds

Antbirds are a family of over 230 species native to Central and South America. These birds primarily feed on ants and other small insects found in the understory of tropical rainforests. Antbirds have several adaptations that make them effective ant predators. 

They have long, sharp beaks for picking insects off trees and leaf litter. Their small size allows them to hop through dense forest vegetation, while their keen eyesight helps them spot small prey.

Flickers

Flickers are a genus of woodpeckers found throughout the Americas. Unlike other woodpeckers that primarily hunt on trees, flickers often forage on the ground, making ants a significant part of their diet. Some desert-dwelling flicker species even nest in cacti and hunt insects on the ground.

Sparrows

While not entirely ant eaters, sparrows are opportunistic feeders that won’t pass up a meal of ants when available. These common backyard birds are found worldwide and feed on insects, including ants, especially when raising their young. Encouraging sparrows to visit your yard provides natural ant control.

Reptiles

While there are many insects that are general insectivores, there are a few species that have focused on ants and termites exclusively. Let’s check out a few of these myrmecophagous reptiles…

Horned Lizards

Also known as “horny toads” or “horntoads,” horned lizards are native to North and Central America. These unique lizards have several features that make them effective ant predators. Their flattened body shape allows them to blend in with their surroundings, while their sticky tongue is perfect for capturing ants. 

They also could squirt blood from their eyes as a defense mechanism. Most horned lizard species feed almost entirely on ant colonies, slowly picking up ants with sticky tongues.

Blind Snakes

Blind snakes are small, fossorial snakes in various parts of the world. Despite their tiny size, these snakes are voracious ant and termite larvae predators. Blind snakes have several adaptations for their ant-eating lifestyle. 

They have a small, smooth body that moves through soil and ant tunnels. They also have special smell glands that track ant trails and can eat many ants’ eggs and larvae.

Arthropods That Feed on Ants

The arthropod world contains ant predators, including other insects and arachnids. These small creatures have evolved various strategies for hunting and consuming ants.

Antlions

Antlions are insects known for their unique hunting strategies. The larvae of these insects build conical pits in loose soil to trap passing ants. When an ant falls into the pit, it struggles to climb out of the loose soil, eventually falling into the waiting jaws of the antlion at the bottom.

Assassin Bugs

Some assassin bugs, like Acanthaspis petax, have evolved to prey almost exclusively on ants. 

These clever insects use a fascinating camouflage technique. They cover their bodies with the carcasses of dead ants, and this macabre disguise allows them to invade ant colonies undetected. Once inside, they use their long, venomous mouthparts to feed on the ants.

Spiders

Jumping spiders and wolf spiders often feed on ants, especially in their smaller life stages. These arachnids are not alone, as most spiders will feed on ants when given the chance.

In fact, anywhere there are ants, there is likely a species of spider that feeds on these ants. You can encourage spiders by minimizing your use of pesticides and moving spiders outside when you find them in your home. 

Ants

Surprisingly, one of the most effective predators of ants is other ants. Several ant species have evolved to prey on their kind. Army ants raid other ant colonies, quickly overwhelming and consuming their victims. 

Raider ants survive by raiding other ant colonies, stealing their food, larvae, and eggs. Argentine ants are an invasive species known to displace and prey upon native ant species in areas they colonize.

Benefits of Natural Ant Predators

Encouraging natural ant predators provides several advantages if you’re looking to control ant populations:

• Eco-friendly pest control without harmful chemicals
• Sustainable, long-term solution that maintains ecological balance
• Increased biodiversity in gardens and outdoor spaces
• Cost-effective alternative to professional pest control services

By creating a welcoming environment for these natural ant predators, you harness the power of nature to keep ant populations in check.

How to Attract Natural Ant Predators

To encourage natural ant predators in a garden or yard, we recommend trying the following strategies:

• Provide suitable habitats: Create areas with native plants, leaf litter, and hiding spots for various ant predators.
• Avoid pesticides: Minimize chemical pesticides that harm beneficial insects and other ant predators.
• Install bird feeders and baths: Attract insect-eating birds by providing food and water sources.
• Plant ant-repelling herbs: Grow mint, lavender, or rosemary to naturally prevent ants while attracting their predators.

Final Thoughts About What Eats Ants

Learning more about the diverse range of creatures that prey on ants offers a fresh perspective on natural pest control. From the specialized adaptations of anteaters and horned lizards to the clever hunting strategies of antlions and assassin bugs, nature has developed numerous ways to keep ant populations in check. 

By encouraging these natural predators and creating a balanced ecosystem in their yards, you can effectively manage ant problems without relying solely on chemical treatments.

While it may take time for natural predators to establish themselves, the long-term benefits of this approach extend beyond just ant control. A yard teeming with diverse wildlife helps manage pest populations and creates a more vibrant and sustainable outdoor environment. 

As you become more aware of these natural pest control methods, you can work harmoniously with nature to maintain a healthy balance in your outdoor spaces.
