An excellent general predator! Praying mantis consumes aphids, beetles, flies, mosquitos, moths, caterpillars and any insect they can catch. Praying mantis, an insect with an innate killer attitude, is a great garden predator. One egg case hatches many tiny babies that quickly disperse throughout your garden. Your egg case contains approximately 40 to 400 eggs.

Mating occurs again in early fall and more egg cases will be laid that will hatch the following summer. The egg case is laid as a foam that hardens into a spongy almost indestructible mass, usually laid attached to a shrub, weed, grass, etc., a few feet off the ground. The egg mass survives freezing, thawing, rain and all the elements to hatch in the early summer to start the cycle again.

Features:

Hatching will occur by June
Egg case contains 40 to 400 young mantis
Most often green but sometimes brown
Very territorial, will create a home where hatched
Feeds on anything they can catch
Late summer mating season

How to apply:

Place egg case outside in the spring attaching the egg case using the included mesh bag in a plant, shrub or tree 1 to 1.5 m (3 to 5 ft.) above ground, or to observe, place in sealable white paper bag and place inside in south facing window checking daily. Tiny mantis will hatch in 1 to 8 weeks and all eggs will hatch within 1 to 2 hours, leaving the egg case visibly unchanged. Release tiny mantis immediately outside onto plants after the hatching occurs. They will quickly disperse throughout your yard to mature and lay eggs, continuing your population next season.

How much do I need?

One egg case covers approximately 90 sq. m (1000 sq. ft.)

Awesome. Wanted to get this off of Amazon before but they wouldn't ship to Canada.
**Edit I think it was the butterfly one I wanted to order but they wouldn't ship.

HD shipping is just over 5$ around MTL. I'll probably go the Costco route then. As OP stated they are BO there, but these hatch by June, so hopefully they'll be back in stock by then

Do they get in your house?
I am interested in this religious mantis.

edit - According to the specs, one box will cover 1000 sqft? wtf? so 40-400 mantises can't take care of more than 1000 sqft of garden?

Majority of them will die and/or eat each other on the way to maturity. I'd imagine you'd be lucky to have a handful left in the end.

This... is such a unique deal that I would want to buy them just to set them free! Like a little religious insect army!

I got one last year and only about 4-5 successfully hatched, and then a couple of weeks later, I only saw 2-3 around, and a month later, all were gone. They were so small that it's hard to believe they'd be able to "hunt" insects. More likely they were hunted by birds instead.

That's the one problem is that birds eat them. But another is they get much better at hiding when they get older.

Probably only 5% out of 40 to 400 will actually survive and half of those will go eat your neighbors bugs instead.

Also, yes, it's annoying when people try to imply that Mantids are religious.

Will these help with a hornets/wasp problem in my back yard? They keep building a nest somewhere on my deck or kitchen window.

One on one? 50/50
Mantis vs hive? Hive wins.

Your hive issue stems from a bigger hive that's somewhere out there and keeps pooping out new queens.

It sounds like some people are looking for a deal on atheist mantis egg case.
