Product Description

Chinese Praying Mantis (Tenodera sinensis). They are one of the best predator insects, eating about any bug except the valuable Lady Bugs. Your Praying Mantis eggcases are currently refrigerated to regulate hatching; once removed and exposed to warm temperatures of 70 to 90 degrees F., the average hatch time is 10-20 days, but can take up to 8 weeks. Simply refrigerate the egg cases until you are ready. Each eggcase will yield from 50-200 baby Praying Mantis. Most hatch at once, but some may hatching may take up to 8 weeks. Generally purchased by mantid & insect enthusiasts, hobbyists, school teachers, or most important for garden pest control. With the egg case we include egg hatching, care instructions.

5.0 out of 5 stars Put the ootheca in full sun.
Reviewed in the United States on May 5, 2018
Ordered 2 on Sunday ( four ootheca total ). Delivered on Thursday.
I kept them in the included hatching kits for two and a half weeks on a shady porch.
Outside temps were in the 50's-60's at night and 70's-85 in the day. Nothing happened for two and a half weeks.
I figured the nymphs couldnt tell it was spring yet due to a lack of heat and light so I removed them from the hatching kits and put them on wooden food skewers and put them in the garden on a Sunday afternoon. ( 3 weeks after ordering/ two weeks and three days after they arrived.)
One was in full sun, the others again closely shaded by some of my plants.
When I came home for lunch on Monday one of the eggs in shade was hatching out. I was somewhat disappointed by how many I could see but I was still pleased that they were hatching. ( I saw about ten babies )
On Wednesday at lunch, the one in full sun was hatching out like crazy. I figure at least 100 came out of that ootheca.
I realized that full sun got the best results and I put them all in full sun including the 1st one that hatched in shade. Thursday at lunch the 3rd ootheca was hatching out. Again with at least a hundred babies if not more. As i am writing this it is Saturday morning and I am hoping the 4th one will hatch out today.
All in all i am very pleased with the results and the cost.
Some notes: the shipping cost more than the eggs themselves.
And the hatching kits appear to be white air sickness bags with a clear cellophane plastic window on one side and I will not use them again.
Ootheca come attached to the remnants of twigs that mama mantid laid them on. I GENTLY removed the twig and replaced them with the skewers... flat side of the egg down an then I just stuck the other end of the skewers in the soil.
Bottom line is I plan to buy four more in a month and hatch them in full sun on the other side of the yard.
Very Happy customer!!!
UPDATE: The fourth ootheca hatched out today ( the following Thursday. )

5.0 out of 5 stars Great success! Heat is what matters, not light.
Reviewed in the United States on May 2, 2022
I've had great success with these egg sacs, aka oothecas! In case you've read some of the negative reviews and you're concerned or unsure, here's all you need to know:

- The instructions state that the praying mantis nymphs will start hatching "when it's warm enough." That phrase means different things for people in different parts of the world. I live in the northern US and hatched these at the end of April after nine days. I had them sitting on a heat mat in my greenhouse cabinet with no grow lights on. The lights don't matter (unless they're producing heat) - heat is what drives the hatching process.

- Some reviews state that the nymphs are an invasive species. Please read the full description and the instruction card to ensure you are protecting your ecosystem before releasing outdoors. If you're in the States, you can always reach out to your state's DNR office to ask about releasing them in your area. I researched all of the native mantis species where I live and confirmed these are not invasive where I am, and I'm not sure where else they are invasive. You can also reach out to the seller to ask questions before buying if you have concerns that are not answered in the description or FAQ.

- There is always a chance one or several oothecas won't hatch. Some reviews make it seem like the possibility for these never hatching is very high, and that is not the case. If you provide enough heat (or wait until your weather is warm enough for them), they will probably hatch. Again, there is and always will be a chance they won't. The only way you can guarantee you will get praying mantis nymphs is if you buy them already hatched from a nursery or pet store.

I hope this helps! Good luck with your oothecas and have fun!!

5.0 out of 5 stars So much fun
Reviewed in the United States on May 14, 2022
The purchase said it was $12 for 2 egg sacks. They gave me 4. I put each egg sack on a stick so they didn't touch the floor of the bag. The back is small for 4 egg sacks to hatch but it worked very well just to keep them hydrated until they started hatching. You just mist the bag and keep it in the window. Nothing else to it. When they first started hatching I placed the bag in the butterfly net cage so they had space to dry off and spread out. 2 out of the 4 hatched first. So we released those outside. I kept an eye on the other 2 eggs. 1 more hatched after 4 more days. Then there was 1 left. It still took another 5 days for the last egg. So I well got my money worth out of 4 eggs. They were so cute. I saw some reviews that said the eggs never hatched. You have to keep the sacks moist and not let them get too hot or too cold. I'm in Florida so I kept them in a sunny window and misted them everytime the bag was dry. The hatching took time and they int hatch at the same time. It was very easy and fun to watch.
