Praying mantises, a natural ally to help reduce insects in the garden!
The praying mantis (Tenodera sinensis) ootheca is a popular biological control option for gardeners who want to complement their practices with a more natural approach. Offered in collaboration with [Partner Name] , this ootheca can produce, once conditions are right, an average of 40 to 200 young mantises (nymphs) that quickly disperse into the environment.
The praying mantis is a generalist predator : it hunts a wide variety of insects in the garden (e.g., grasshoppers, crickets, flies, moths, caterpillars, aphids, etc.). It is an interesting solution for maintaining the balance of the garden, especially when insect pressure is high.
At Les Semis de la Seigneurie, we have been using oothecae in the garden for years : it is a solution we know well and recommend as a complement to good practices (observation, diversity in the garden, targeted interventions).

Use in Quebec (zone 4b and above)
In Quebec, installation usually takes place in the spring (often in May) , when temperatures become more stable. The goal is to release them early enough to allow the mantises time to grow and be active in the garden during the season.
⚠️ Avoid a release that is too late: ideally before the end of August .
Producer's advice
💚 Keep refrigerated (not frozen) until installation
🌿 Install in the shade, sheltered from direct sunlight and heavy rain
🪢 Hang 1 to 1.5 m high from a sturdy branch/shrub
🕊️ Recommended option: mesh bag to protect against birds/rodents (1/4 to 1/2 inch mesh)
🌥️ Set up in the early evening or on a cloudy day

🕊️ Recommended option: mesh bag to protect against birds/rodents (1/4 to 1/2 inch mesh)
🌥️ Set up in the early evening or on a cloudy day
What to expect (hatching)
In warm and stable conditions ( 24–27°C / 75–80°F ) with daily misting, hatching can take 10 to 15 days . In spring, with fluctuating temperatures, it can take 6 to 8 weeks .
The nymphs often disperse within 1 to 2 hours : it's normal not to "see" the hatching. And a hatched ootheca doesn't necessarily look very different from an unhatched one.
