Attracting praying mantises to your garden starts with providing the right shelter and avoiding broad-spectrum pesticides. Learning how to attract praying mantis is easier than you think, and these beneficial insects can help control pests naturally. They are fascinating creatures that add a unique touch to any outdoor space.
Understanding Praying Mantis Behavior
Before you start, it helps to know what mantises need. They are ambush predators, meaning they sit and wait for prey. They do not eat plants. Their diet includes aphids, caterpillars, flies, and even small crickets. A single mantis can consume many garden pests each day.
Mantises are territorial. They do not live in colonies. Each one needs its own hunting ground. If you see one, it likely found a good spot with plenty of food and cover. Your goal is to create a space that meets these basic needs.
Life Cycle Basics
Mantises go through three stages: egg, nymph, and adult. The egg case, called an ootheca, is laid in fall and hatches in spring. Nymphs look like tiny adults and begin hunting immediately. Adults live through summer and into fall, when they mate and lay eggs.
Knowing this cycle helps you time your efforts. For example, providing egg-laying sites in late summer is key for next year’s population. You want to support them at every stage.
How To Attract Praying Mantis
Now lets get into the practical steps. The core strategy involves three things: habitat, food, and safety. When you provide these, mantises will come and stay. Here is a breakdown of what to do.
Provide The Right Shelter And Perches
Mantises need places to hide and hunt. They prefer dense vegetation where they can ambush prey. Tall grasses, shrubs, and flowering plants work well. They also need sturdy stems to climb and hang upside down when molting.
- Plant native grasses like switchgrass or little bluestem
- Include flowering perennials such as coneflower, black-eyed Susan, and goldenrod
- Leave some areas of your garden a bit wild and untidy
- Add trellises or tall stakes for climbing
- Keep a few dead branches or old stems in place over winter
These structures give mantises places to perch and ambush. They also provide cover from birds and other predators. A garden with varied heights and textures is most attractive.
Grow Plants That Attract Prey Insects
Mantises follow their food. If your garden has lots of small insects, mantises will come to hunt them. You can boost prey populations by planting flowers that attract pollinators and other bugs. This creates a natural food supply.
Good plants for attracting prey include:
- Dill, fennel, and parsley (attract caterpillars and aphids)
- Marigolds and nasturtiums (draw in small flies and beetles)
- Sunflowers and zinnias (support many insect species)
- Clover and alfalfa (host leafhoppers and other small bugs)
Do not worry about a few pests. They are food for mantises. A balanced garden has some pest insects, but mantises help keep them under control. You are creating a mini ecosystem.
Avoid Pesticides And Chemical Sprays
This is the most important rule. Broad-spectrum pesticides kill mantises directly. They also kill the insects mantises eat. Even organic sprays like neem oil can harm nymphs. If you must treat a problem, use targeted methods like hand-picking or insecticidal soap on specific plants.
Mantises are sensitive to chemicals. They absorb toxins through their exoskeleton. A single spray can wipe out your local population. Instead, rely on natural predators like mantises and ladybugs to manage pests. It takes patience, but it works.
Provide A Water Source
Mantises need water, especially during hot, dry weather. They drink from dew, rain, and small droplets on leaves. You can help by providing a shallow water dish or a mister. A birdbath with pebbles works well, as long as the water is not too deep.
Another option is to mist your plants in the morning. This creates dew-like droplets that mantises can drink. Avoid standing water that breeds mosquitoes. A simple drip tray under a potted plant can also work.
Leave Leaf Litter And Mulch
Mantises hide in leaf litter and mulch. These materials provide cover for nymphs and adults. They also support insects that mantises eat. A layer of organic mulch around your plants is beneficial. Do not rake up every fallen leaf in fall.
Leaving some garden debris over winter is also good. Egg cases are often attached to stems or under bark. If you clean up too thoroughly, you may remove them. Let nature take its course.
Creating A Mantis-Friendly Garden Design
Now that you know the basics, lets talk about garden layout. You do not need a huge space. Even a small balcony or patio can attract mantises if designed well. The key is diversity and structure.
Use Layers Of Vegetation
Think of your garden as a multi-story habitat. Ground cover plants like creeping thyme or sedum provide low hiding spots. Medium-height flowers and shrubs give perching areas. Tall plants and trellises offer high vantage points. This layering mimics natural meadows.
Mantises move between layers as they hunt. Nymphs often stay low, while adults climb higher. By providing all three levels, you support every life stage. It also looks beautiful and full.
Include Evergreen Plants For Winter Cover
Evergreens like boxwood, juniper, or holly provide year-round shelter. Mantises can hide in them during cold months. They also offer early spring cover before deciduous plants leaf out. A few evergreens make your garden more inviting year-round.
Do not overdo it though. Mantises also need open areas for hunting. A mix of evergreen and deciduous plants is ideal. Aim for about 30% evergreen cover in your garden.
Plant In Clusters Rather Than Single Specimens
Clusters of plants create dense patches that mantises love. A single flower is less attractive than a group of five or six. Grouping plants also makes it easier for mantises to move between hunting spots. It creates a connected habitat.
For example, plant a cluster of coneflowers next to a patch of ornamental grass. This gives mantises both cover and hunting ground. They can ambush prey from the grass and then move to the flowers.
Introducing Mantis Egg Cases (Oothecae)
If natural attraction is slow, you can buy egg cases online or at garden centers. This gives your population a head start. However, you must handle them correctly. Here is how to do it.
Where To Buy And What To Look For
Purchase egg cases from reputable suppliers. Look for cases that are firm, not cracked or moldy. They should be attached to a small twig or piece of paper. Avoid cases that look dried out or damaged. A healthy case is about the size of a walnut and light brown.
Most suppliers ship in late winter or early spring. Order early, as they sell out fast. Check reviews to ensure the company has good hatch rates. Some garden centers also carry them in spring.
How To Place Egg Cases In Your Garden
Attach the egg case to a sturdy branch or stem about 2-3 feet off the ground. Use a twist tie or string. Do not glue it, as the glue can suffocate the eggs. Place it in a sheltered spot, out of direct wind and rain.
Choose a location with some sun but also shade. The eggs need warmth to develop, but too much heat can dry them out. A spot under a shrub or near a fence works well. Make sure the case is secure so it does not fall.
When To Expect Hatching
Egg cases hatch in spring, usually when temperatures reach 60-70°F (15-21°C). The exact time depends on your climate. In warmer areas, hatching can occur in March. In cooler zones, it may be May or June. Nymphs emerge over several days.
Do not move the egg case after placing it. The nymphs need to find their own way. They will disperse quickly after hatching. Do not worry if you see only a few at first. Many will survive if conditions are good.
Maintaining A Mantis Population Over Time
Once you have mantises, you want them to stay. This requires ongoing care and a few adjustments to your gardening habits. Here are tips for long-term success.
Reduce Garden Cleanup In Fall
Mantises lay eggs in late summer and fall. The egg cases are often attached to stems, fences, or tree bark. If you cut back all your plants in fall, you may remove these cases. Wait until late spring to do major cleanup. By then, the eggs have hatched.
You can also leave some stems standing through winter. This provides shelter for other beneficial insects too. A slightly messy garden is a healthy garden. Embrace a bit of wildness.
Monitor For Pests Without Chemicals
If you see a pest outbreak, resist the urge to spray. Mantises will eat many pests, but they cannot control a sudden explosion. Instead, use physical methods like hand-picking, water sprays, or diatomaceous earth. These are safe for mantises.
You can also introduce other beneficial insects like ladybugs or lacewings. They work together with mantises. A diverse predator community is more resilient. Avoid any product labeled as “broad-spectrum.”
Provide Additional Food If Needed
In very dry years or early spring, prey may be scarce. You can supplement by releasing small insects like fruit flies or aphids. Or you can buy live crickets from a pet store. Place them near mantis perches. This is not necessary in most gardens, but it can help.
Do not overfeed though. Mantises will eat only what they need. Too many prey insects can attract other pests. A balanced garden provides enough food naturally. Only supplement if you see mantises looking thin or inactive.
Common Mistakes To Avoid
Even with good intentions, people make errors. Here are the most common ones and how to avoid them.
Using Too Much Mulch
Mulch is good, but too deep can trap moisture and cause mold. It can also hide predators like spiders that eat mantis nymphs. Keep mulch to 2-3 inches deep. Leave some bare soil areas for mantises to hunt.
Planting Invasive Species
Some plants that attract insects are invasive in certain regions. Check with your local extension office before planting. Invasive plants can harm native ecosystems and may not support local mantis species. Stick with native plants when possible.
Overcrowding The Garden
Mantises need space. If your garden is too dense, they may not find enough hunting room. Leave some open areas between plant clusters. This also helps air circulation and reduces disease. Balance is key.
Ignoring Local Climate
Different mantis species have different needs. In North America, the Chinese mantis and Carolina mantis are common. Research which species live in your area. Some are native, others introduced. Choose plants and practices that suit your climate.
