What Are Assassin Bug Enemies? (The Complete List)

Have you ever encountered a creepy crawly assassin bug and wondered what its enemies are? Assassin bugs are powerful predators that can make quick work of pesky insects in your garden, but they too have some powerful enemies that you should know about.

In this article, we’ll take a look at the complete list of assassin bug enemies, from spiders to centipedes to parasitic wasps.

Read on to find out more about these predators of the assassin bug!

Short Answer

The primary enemies of assassin bugs are other predatory insects like spiders, ants, and wasps.

Larger predators, like birds and lizards, may also feed on them.

Additionally, parasites, such as mites or nematodes, may attack them.

Insecticides can also be effective against assassin bugs, as they are susceptible to many of the same chemicals that affect other insect pests.

What Are Assassin Bugs?

Assassin bugs are predatory insects that are classified as true bugs, meaning they have a stylet, or a piercing mouthpart, to suck the juices of their prey.

They are found in many parts of the world, including tropical and temperate climates, and can range in size from less than a quarter-inch to over an inch in length.

Assassin bugs are typically brown or black in color and have a somewhat flattened, elongated shape.

Despite their small size, they are fierce predators and feed on a variety of other insects, such as caterpillars, aphids, and grasshoppers.

Because of their predation of pests, they are often considered beneficial to humans.

However, assassin bugs have natural enemies of their own.

These enemies include other predatory insects, such as spiders, centipedes, and ants; parasitic wasps; and birds and lizards who may feed on them.

To protect themselves, assassin bugs have developed a variety of strategies, such as camouflage or mimicry to blend in with their environment.

Assassin bugs may also use their piercing mouthparts to inject a venom into their prey, which immobilizes them before they can be consumed.

Assassin Bug Enemies

Assassin bugs are some of the most feared and respected predators in the insect world.

They are true bugs, meaning they have a stylet, or a piercing mouthpart, to suck the juices of their prey.

So, what are the enemies of assassin bugs?

There are many different types of predators that assassin bugs have to contend with.

Other predatory insects such as spiders, centipedes, and ants are all potential threats.

As these predators hunt for food, they can take down an assassin bug if they come across one.

Birds and lizards are also known to feed on assassin bugs.

To protect themselves, assassin bugs have evolved a variety of defense mechanisms.

One of these is camouflage or mimicry.

By blending in with their environment, they can avoid detection by potential predators.

Additionally, assassin bugs have a thick exoskeleton that acts as armor against attacks.

In addition to these predators, assassin bugs also have to contend with parasitic wasps.

These wasps will lay their eggs in the bodies of the assassin bugs, which will eventually hatch and consume the host.

The parasitic wasps are usually able to fly away before the assassin bug can respond.

So, while assassin bugs are a highly effective predator, they still have their own enemies.

Other predators, birds, lizards, and parasitic wasps all pose a potential threat to these bugs.

To protect themselves, assassin bugs have evolved camouflage and a thick exoskeleton.

It is fascinating to see how these bugs have adapted to their environment and the threats they face.


Assassin bugs have a lot of natural enemies, and spiders are one of them.

Spiders hunt for their prey by spinning webs, which can ensnare assassin bugs that fly into them.

Some spiders, such as jumping spiders, are even equipped with special sensory organs that allow them to detect assassin bugs even when theyre not in the web.

Furthermore, spiders have tough exoskeletons that make them difficult to penetrate with an assassin bugs stylet.

In other words, these eight-legged predators are a formidable foe for assassin bugs.

To defend themselves, assassin bugs may use their camouflage skills to blend in with their environment and avoid being spotted by spiders.


Centipedes are one of the most common natural enemies of assassin bugs.

These arthropods have up to 177 pairs of legs and are often found in damp environments.

They hunt their prey by injecting venom through their fangs, as well as by using their pincers.

Centipedes can be a formidable foe for assassin bugs, as they are often larger and more powerful.

When an assassin bug is confronted by a centipede, it will use its camouflage and mimicry to blend in with its environment and avoid attack.

Assassin bugs may also use their long legs and sharp claws to defend themselves from centipedes.

Assassin bugs have been known to use their legs to grab onto the centipede’s head and feet, and then use their sharp claws to puncture the centipede’s body.

In this way, assassin bugs can outwit and outmaneuver their centipede enemies.


Ants are one of the main enemies of assassin bugs and can be hard for the bugs to defend against.

Ants are omnivorous, meaning they consume plants and animals, and they are aggressive in protecting their colonies.

They have powerful mandibles that can easily crush an assassin bug’s body, making them difficult to repel.

They also have a good sense of smell and can detect the presence of assassin bugs in their nests.

To avoid being detected, assassin bugs may use camouflage or mimicry to blend in with their environment.

They may also use defensive postures, such as raising their head and abdominal segments, to ward off ants.

Additionally, some species of assassin bugs have evolved to produce pungent secretions that can help deter ants from attacking.

Parasitic Wasps

Parasitic wasps are one of the most common enemies of assassin bugs.

These wasps lay their eggs on or inside the body of their prey.

When the eggs hatch, the larvae feed off the insect, eventually killing it.

Parasitic wasps are especially effective against assassin bugs because they can lay their eggs in or on the body of the bug in order to avoid being eaten.

While the wasps are small, they are formidable predators and can quickly take down an assassin bug.

In addition, the wasps can lay eggs in or on multiple insects, allowing them to spread quickly and potentially decimate a population of assassin bugs.

Other Predators

Assassin bugs have many enemies in the wild, including other predatory insects.

These enemies include spiders, centipedes, and ants.

Spiders, for example, can be a formidable foe for assassin bugs, as they have the capacity to spin webs to capture their prey.

Centipedes, on the other hand, have powerful legs and jaws, allowing them to quickly catch and kill their prey.

Ants, which often live in large colonies, can be especially dangerous to assassin bugs, as they are able to swarm and overwhelm their prey.

In addition, parasitic wasps can be potential predators for assassin bugs, as they lay their eggs on or in the assassin bug, which the larvae then feed on.

Birds and lizards can also be a problem for assassin bugs, as they often have a taste for the tasty bugs.

In order to protect themselves from their predators, assassin bugs will often use camouflage or mimicry to blend in with their environment.

This means they will look like something else in their surroundings, such as a leaf or twig, making it more difficult for predators to spot them.

Assassin bugs also have the ability to emit a foul-smelling liquid from their bodies when threatened, which can act as a deterrent to potential predators.

Final Thoughts

Assassin bugs are an important part of the insect ecosystem, and it’s important to be aware of the predators that threaten them.

Knowing their enemies can help you protect assassin bugs that you may find in your own yard.

If you’re interested in helping assassin bugs thrive, consider adding some of their natural predators into your outdoor space, such as spiders, centipedes, ants, and parasitic wasps.

Not only can this help protect assassin bugs, but it can also help reduce the population of pests in your garden.
