The praying mantis, with its striking appearance and formidable hunting prowess, is a fascinating insect that often finds its way into gardens. While some gardeners view these creatures as beneficial allies in pest control, others see them as pests that need to be eliminated. The question of whether to remove praying mantis from your garden is complex and depends on several factors, including the type of garden you have, the local ecosystem, and your personal gardening goals. In this article, we will delve into the world of praying mantis, exploring their role in the garden, their benefits and drawbacks, and ultimately, helping you decide whether these insects are welcome guests or unwelcome visitors.
Introduction to Praying Mantis
Praying mantis are insects belonging to the order Mantodea, characterized by their elongated bodies, long, slender legs, and most distinctly, their large, triangular heads that can turn a full 180 degrees. They are known for their unique hunting style, where they lie in wait, often mimicking leaves or twigs, and then strike with rapid speed, capturing prey with their spiked forelegs. This predatory behavior makes them formidable hunters, capable of controlling pest populations in gardens.
Habitat and Distribution
Praying mantis can be found in various habitats around the world, including gardens, forests, and grasslands. They prefer warm, sunny spots, often near flowers or other areas where insects are abundant. In gardens, they can be attracted to herbaceous plants, flowers, and even vegetable crops. Their ability to blend into their surroundings makes them challenging to spot, but their presence can be indicated by the absence of other insects or the discovery of their egg cases (oothecae) attached to plants or fences.
Life Cycle and Behavior
Understanding the life cycle and behavior of praying mantis is crucial for appreciating their role in the garden. Praying mantis undergo incomplete metamorphosis, starting as eggs that hatch into nymphs, which look like smaller versions of adults. These nymphs go through several instars, shedding their skins as they grow, before reaching adulthood. Adult praying mantis are known for their predatory behavior, feeding on a wide range of insects, including pests that can damage garden plants. However, they are not discriminatory in their predation and will consume beneficial insects as well.
Benefits of Praying Mantis in the Garden
The presence of praying mantis in the garden can have several benefits, primarily related to pest control. Here are some of the advantages of having these insects in your garden:
Praying mantis are natural predators of many garden pests, including aphids, whiteflies, and mosquitoes.

How can I attract praying mantis to my garden?
Attracting praying mantis to your garden can be achieved through several methods. One of the most effective ways is to create a diverse and welcoming environment with a variety of plants that attract different types of insects. Praying mantis prefer gardens with tall vegetation, where they can hide and hunt, so incorporating plants like sunflowers, ornamental grasses, or flowering shrubs can be beneficial. Additionally, avoiding the use of pesticides is crucial, as these chemicals can harm or kill praying mantis and other beneficial insects.
Another approach to attracting praying mantis is to provide them with potential egg-laying sites. Female praying mantis often look for protected locations to deposit their egg cases, such as on branches, fences, or garden decor. By offering these types of structures in your garden, you can encourage females to lay their eggs, increasing the chances of having a population of praying mantis in your garden the following year. It’s also important to maintain a source of water, as praying mantis, like all living creatures, need access to water for drinking and possibly for their prey.
Should I remove praying mantis egg cases from my garden?
Praying mantis egg cases, also known as oothecae, are protective capsules that contain the eggs of the mantis. These structures are usually deposited on plant stems, branches, or other garden features by the female mantis in the fall. Each egg case can contain hundreds of eggs, which will hatch in the spring. Removing these egg cases can be counterproductive if you wish to have praying mantis in your garden, as it would eliminate the potential for a new generation of these beneficial insects to emerge and contribute to pest control.
However, there might be situations where you would consider removing egg cases, such as if they are attached to plants that you plan to prune or move indoors for the winter. In such cases, it’s advisable to relocate the egg case to a suitable outdoor location where it can remain over winter and hatch naturally in the spring. It’s essential to handle the egg case carefully to avoid damaging it, as this can reduce the chances of successful hatching. By leaving the egg cases intact or relocating them thoughtfully, you can support the lifecycle of praying mantis and enjoy their benefits in your garden throughout the growing season.
Can I keep praying mantis as pets and how do I care for them?
Keeping praying mantis as pets can be a fascinating and educational experience, offering a unique opportunity to observe these insects up close. Praying mantis are relatively low-maintenance pets, requiring a well-ventilated, secure enclosure with adequate space to move and hunt. The enclosure should be equipped with branches or other perches for the mantis to climb on and possibly a heat source, as many species of praying mantis are sensitive to temperature. Feeding them can be as simple as releasing live insects into their enclosure, although a varied diet that includes different types of prey can help ensure their nutritional needs are met.
Caring for praying mantis involves attention to their specific needs, including humidity, lighting, and temperature, which can vary depending on the species. It’s also crucial to handle them gently and infrequently, as excessive handling can stress the mantis and lead to injury or death.
