Are Praying Mantises Dangerous to Dogs A Comprehensive Guide

In this comprehensive guide, we will explore whether praying mantises can be dangerous to dogs, how to keep your pup safe, and address some frequently asked questions about this intriguing topic.

Introduction to Praying Mantis

Praying mantises, scientifically known as Mantodea, are fascinating insects characterized by their distinctive upright posture, large front legs, and keen hunting abilities. They are often considered beneficial for gardens due to their role in controlling pest populations. However, concerning your dog’s safety, it’s natural to have concerns. 
While praying mantises are generally harmless to dogs, it’s important to note that they can defend themselves if provoked. Their large front legs have sharp spines to catch and hold their prey. Therefore, it’s advisable to supervise your dog when they encounter a praying mantis to prevent any potential harm. Additionally, if your dog tends to eat insects, it’s best to discourage them from doing so as a precautionary measure. 

Anatomy of a Praying Mantis

Before we delve into the potential risks, let’s understand the physical characteristics of praying mantises:

  • Size: Praying mantises vary in size, but they typically range from 0.5 to 6 inches in length. This size difference plays a role in determining their potential threat to dogs.
  • Front Legs: Their most iconic feature, the front legs, are equipped with spines that allow them to grasp and immobilize their prey. This can be of concern when it comes to interactions with dogs.
  • Head: The head of a praying mantis contains compound eyes, which gives them excellent vision and allows them to track movements in their environment.

 This heightened vision is advantageous for hunting, but it also means that praying mantises may be more likely to detect and react to the presence of dogs. Additionally, the head of a praying mantis also houses powerful mandibles that they use to capture and consume their prey, making them potentially dangerous if a dog were to disturb or provoke them accidentally. 

Can Praying Mantises Harm Dogs?

Whether praying mantises can harm dogs is a common concern among pet owners. The response can be either yes or no, depending on several aspects.

Size Matters

The size of the praying mantis plays a significant role in determining whether it can threaten your dog. Smaller mantises, usually around half an inch long, are unlikely to harm a dog. However, more enormous mantises can inflict minor harm. These more giant mantises have sharp front legs that they use to catch and hold their prey, which could cause minor scratches or irritation if they come into contact with a dog’s skin.
However, it is essential to note that praying mantises are generally not aggressive towards animals more significant than themselves and are more likely to flee than attack. 

Praying Mantises and Dogs: A Real Threat?

While praying mantises are not typically aggressive towards dogs and rarely pose a direct threat, there are a few scenarios to consider:

  • Swallowing: Smaller mantises can be accidentally swallowed by dogs while exploring the garden or playing outdoors. In most cases, this won’t harm your pet, as the exoskeleton of the mantis is unlikely to cause digestive issues.
  • Leg Grasping: If your dog investigates a praying mantis up close, there’s a chance that the mantis may use its spiky front legs to grasp your dog’s snout or tongue. This can be uncomfortable and potentially cause minor injuries.
  • Chemical Defense: Some mantis species may release a defensive chemical when threatened. While this is not typically harmful to dogs, it can irritate if it comes into contact with their skin, eyes, or mouth.

 It is essential to monitor your dog if they come into contact with a praying mantis to ensure they do not experience discomfort or irritation. If you notice any unusual symptoms or reactions, it is best to consult with a veterinarian for further guidance. 

Venomous Praying Mantises

The good news is that most praying mantis species are not venomous. They rely on their front legs to capture and immobilize prey. However, there are a few exceptions, such as the giant Asian mantis, known to be evil to its target. It’s important to note that even the venomous mantises are unlikely to pose a significant threat to dogs due to their size.
However, it is still essential to keep an eye on your dog if they come into contact with an evil praying mantis, as some dogs may have allergic reactions or be more sensitive to the venom. If you suspect your dog has been bitten or stung by a venomous mantis, it is recommended to seek immediate veterinary attention to ensure their safety and well-being. 

How to Protect Your Dog from Praying Mantises

Now that we have a better understanding of the potential risks, it’s essential to know how to protect your furry friend from any unwanted encounters with praying mantises.


When spending time with your dog outdoors, it’s crucial to supervise them, especially in areas where you suspect there may be praying mantises. Keep a close eye on your dog to prevent any accidental interactions. Additionally, consider keeping your dog on a leash to have better control over their movements and prevent them from getting too close to mantises.
It’s also important to educate yourself about the specific types of praying mantises in your area and their behavior to better anticipate any potential encounters. 


If your dog has a habit of investigating insects, you can work on their training to discourage this behavior. Teach them basic commands like “leave it” to prevent them from approaching potential threats. Additionally, you can reward your dog with treats or praise when they listen to your commands and avoid coming mantises. Consistency and positive reinforcement are vital in reinforcing the desired behavior.
Remember to be patient and understanding during the training process, as it may take time for your dog to grasp and obey these commands fully. 

Gardening Awareness

If you have a garden, be aware of the presence of praying mantises and take measures to relocate them if necessary. This not only protects your dog but also helps maintain a balanced ecosystem. Additionally, consider creating a designated area for your dog to play and explore in the garden, away from potential mantis encounters. This will provide a safe space for your dog while still allowing them to enjoy the outdoors.
Remember to regularly inspect your garden for any signs of mantises and take appropriate action to ensure the safety of both your dog and the local wildlife. 

First Aid

In the unlikely event that your dog encounters a praying mantis and sustains minor injuries, clean the affected area with mild soap and water and consult your veterinarian for further advice. If your dog’s injuries are more severe or show signs of an allergic reaction, such as difficulty breathing or swelling, seek immediate veterinary care. It’s essential to act quickly to prevent any complications and ensure your dog receives the necessary treatment. 

Additional Resources

If you want to learn more about praying mantises and their role in the ecosystem, or if you have specific concerns about your dog’s interactions with insects, consider consulting the following resources:

  • Local Veterinarian: Your local veterinarian is your best source of information and guidance regarding your dog’s safety and well-being.
  • Entomology Organizations: Local or national entomology organizations can provide valuable insights into the behavior and habits of praying mantises.
  • Pet Training Classes: Enrolling your dog in pet training classes can help you teach them essential commands, such as “leave it,” to prevent unwanted interactions with insects and other potential hazards.
  • Gardening and Pest Control Resources: Gardening guides and pest control resources can help you better understand the role of praying mantises in maintaining a healthy garden ecosystem.

By combining your knowledge of praying mantises with responsible pet ownership practices, you can create a safe and enjoyable environment for your dog while also appreciating the wonders of the natural world.

Can my dog be allergic to praying mantises?

Allergies to praying mantises are infrequent in dogs. While it’s theoretically possible for a dog to be allergic to the substances released by mantises when threatened, such allergies are not a common concern for pet owners.

Should I remove praying mantises from my garden to protect my dog?

Can praying mantises harm small dog breeds more than larger ones?

Praying mantises can potentially pose more of a minor threat to smaller dog breeds due to their size. While the risk is still minimal, smaller dogs might be more susceptible to discomfort if a mantis uses its front legs to grasp their snout or tongue. Supervision and training can help mitigate this risk for all dog breeds.

Remember, while the world of insects is diverse and fascinating, your dog’s safety should remain a top priority. By staying informed and taking the necessary precautions, you can provide a secure and enjoyable outdoor experience for you and your furry friend.
