Can a Praying Mantis Eat a Mouse?

Many people keep mice as pets and are afraid of garden insects like praying mantis because they can sting or bite, causing discomfort and death of the pet.

Can a Praying Mantis Eat a Mouse? Praying mantis can eat a mouse due to hunger and predatory nature as their carnivorous diet allows them to hunt living prey animals to boost their energy level. They kill a mouse when it is easy to target by capturing its neck with forelegs and restricting motion. Commonly, giant mantises target mice as prey, as smaller ones cannot grasp them.

There are a wide variety of mouse predators in nature, like mongoose, owls, falcons, snakes, carnivorous insects, or praying mantis.

How does a praying mantis eat a mouse?

They can easily capture a mouse because they can handle prey 3 times larger than their bodies. They wait for the prey to come closer and silently sit in the hidden corner.

In addition, praying mantis do not move and stay motionless, as any movement can lead to the disappearance of the roaming prey. Accordingly, they blend with background vegetation and hide themselves.

It quickly makes a deadly strike on the neck of a mouse and pinches its body with spikes on its forelegs. This strike is followed by biting behavior when they bite its neck with strong mandibles.

These sharp spikes and mandibles can cause injuries or wounds on their necks, leading to animal death. They begin to eat it after decapitation as they cannot retaliate after head removal.

Moreover, they use mandibles to tear the body of the prey and break larger pieces of flesh into small portions. They cannot engulf large mice without breaking muscles with mandibles.

Stylet in their mouth helps suck fluids or other juices inside the body as it is a long-sucking organ that resembles a tongue in higher vertebrates.

This way, they deal with a living mouse and finish it up eating within a few minutes, as it takes almost 15 to 20 minutes to consume it.

However, this time can increase depending on the size and weight of the targeted mice, as larger animals need more time.

Why does a praying mantis eat a mouse?

Praying mantis are carnivorous insects that prefer to eat insects, arthropods, invertebrates, and small vertebrates according to the availability of food sources.

Easy to target

They are smaller creatures that prefer to choose tiny prey animals to ensure successful hunting because they can quickly grasp a small body.

On average, mice are almost 2.5 to 4.4 inches long, and praying mantis are also 2.2 to 5 inches long.

They can efficiently capture prey 2 to 3 times larger than their bodies.

They do not miss an opportunity to grab a mouse if it is in their access or roaming in their territories while searching for food.


They can attack a mouse when hungry and find no other suitable food source in their surrounding areas.

This small animal can become a good source of nutrition for them because it can provide fats, as they contain around 14% to 26% fats in their bodies.

In addition, average-sized mice contain almost 16% to 18% protein, which can add a good protein content to the mantis diet. Some other nutrients and minerals are also present in them.

A hungry or starving insect quickly pounces upon it with a quick strike when it is about to die due to hunger. They can ensure survival by eating the nutrient-rich bodies of the mice.

Boost energy level

Praying mantis feel sluggish and lethargic due to the absence of food resources or shelter and hot weather.

They find mice as a source of food and water and kill them to boost their energy level. They suck fluids from their body and consume the meat to revive their energy.

Moreover, they do not leave their territories and eat only food sources available in their territory. So, they miss a chance to attack prey when they feel lethargic due to a lack of energy.

They need energy for efficient hunting and defensive fights; otherwise, they lose the battle when they lack the energy to compete with other insects and invertebrates.

Carnivorous diet

Their dietary habits do not involve plant-based food items like seeds, fruits, leaves, etc. They rely only on animal-based foods and primarily eat other insects.

Their predatory nature also allows them to attack small invertebrates, amphibians, reptiles, and other animals that are easier to capture, consume, and digest.

Accordingly, they also eat mice whenever they encounter them in their territories. They cannot live without eating these small animals as they have carnivorous diets.

Predatory nature

These ambush predators attack other small creatures, whether they are responsible for posing a threat or not, because they are a food source.

Moreover, they have a predatory nature and quickly attack small living organisms to kick them out of the territory or meet their nutritional needs.

So, it is less likely for mice to leave their territories alive when they enter the territory of large mantis like Chinese or African mantis, as their fate is to die and become a food source for them.

How does a mouse fight against a praying mantis?

Interaction between mice and praying mantis is not common, as they have varying habitats and behavior. However, both organisms are adapted to ensure their survival by threatening attackers.

A mouse commonly exhibits a defensive behavior when it feels a threat, but its primary response is to run away from the spot. They are fast runners and hide quickly.

In addition, they produce a threatening sound to give a warning signal that can help avoid a predator. They emit high-pitched sounds or distress calls to bring their fellows on the spot for help.

I found a mouse making terrible sounds in the garden area, and I saw a mantis attacking its neck with mandibles after reaching the spot.

Some other aggressive displays are also observed for defending themselves, including puffing for furs, wagging their tails, and a distinct posture related to aggression.

Puffing of bodies increases their body size and helps discourage the attacking predators when approaching the mice.

Furthermore, they hide inside holes and run towards the escape routes to get out of the predator’s sight, but their fate is to die most of the time when they do not detect a predator.
