Unleash one of nature's most effective predators in your backyard from The Home Depot, because you can get a Praying Mantis Egg Case for $15.98!

Praying mantises are a natural form of pest control and harmless to humans, as they ward off unwanted insects like fruit flies and serve as a neat educational tool for kids. For comparison, this deal is also available at Costco.ca for $19.99. Other nifty details include:

  • Each egg case contains 40-400 eggs that will hatch in June and disperse in your garden
  • Mantises feed on fruit flies, gnats, aphids, flies, mosquitoes, beetles, moths, caterpillars and even grasshoppers
  • Hatching occurs in June when the weather is warm, immediately dispersing and setting up their own territory
  • Very territorial and will create a home where hatched
  • One egg case covers approximately 90 square-metres (1000 square-feet)

This offer is available online until mid-June, as most egg cases will hatch around that time. HomeDepot.ca offers free shipping with most orders over $49.00 and free curbside store pick-up with no minimum.

    • I must have missed this in previous years as this looks awesome. The Kids will love it, I'll try the paper bag so the kids could see them before releasing them! Does anyone have any recommendations other than what is in the instructions?

      Home Depot is selling them $15.98 so I ordered 2 with free site to store pickup.

      Also considering that Costco may ship via UPS and my shipment from a few weeks ago was delays for 9 days with UPS I'm not eager to order unless it's a great deal.

    • I got this a couple of times and they never hatched even though I followed the instructions. I was pretty sad since I really wanted to see them.

    • I had one last year. I kept it in the house because the family wanted to see the action. It took almost a month, but about 50 of them came out. Fortunately, we were there to see it and quickly put the case outside. It probably took less than 10 minutes for the entire hatching. Had we been out at the time, I would have ended up with them inside my house.

      Worth noting that if you keep the eggs in a container, and the insects hatch without a food source, they'll start eating each other.

      One other point, after the hatching was complete, the egg case looked the same. So, it's really likely that you could buy one of these, miss the hatching, and never know if you bought a dud.

      Lastly, I haven't seen a sign of them since. I have a large yard and they're tough to see at the best of times.

    • After reading some of the negative reviews on this product, I thought I'd tell your about our experience, as it may help you to be successful with the egg casing and babies. First of all, be patient; it takes a long time for the casing to hatch. Do not hatch outside, as the babies will march out and be promptly eaten by other, larger insects and birds before you even get to see that they hatched. Hatch in an old aquarium with a lid or a large jar. We were lucky enough to see our egg casing hatch and got literally hundreds of the babies! I do not recommend releasing them right away as previously mentioned, as they will be smaller than the other insects in your yard and will likely get eaten. We transferred groups of the babies into separate jars with a large twig in each, and fed them pinhead crickets for a few weeks...(this reduced cannibalism and made the babies grow fairly quickly). We only set them free on our plants once they were a reasonable size and the weather had warmed #Calgary). We had some huge mantises by the end of the summer and are ordering again this year. Good luck!
      Good review on how to get better results.

    • I bought a single mantis few years ago to help with protecting the garden. I loved it but found him like twice all summer as they're extremely hard to see.

    • Please consider few things before buying/applying mantis on your garden.

      1. Their origin (North American, vs Chinese, Anatolian, etc).
      2. Do you have bee colonies, hummingbirds, etc?
      3. Do you use pesticides and other chemicals?

      It's been reported Chinese are larger than North Americans, e.g. Carolinas, and may be harmful to bee colonies.

    • Costco uses UPS to deliver packages. And my local UPS warehouse is overwhelmed, packages delay for 3-4 weeks.

      Maybe I'll order one and let it hatch in UPS warehouse.

    • I went through this a couple of years ago. Followed the instructions that I found online, put a small branch in a jar with a damp paper towel on the bottom. poke small holes in a jar lid. So, as mentioned they just started hatching and luckily we were home. it was very cool to see that.
      I released them into the backyard as instructed, into my garden beds...never saw any of them again, ever. on the other hand my neighbor doesn't have any insect issues anymore LOL!!!!

      Similar thing happened with live ladybugs, I also bought them that same time from costco.ca, they hatched, released per instructions (and I had easily 700+) - never saw them again :)

    • Do it really help with reducing swamps of mosquitoes?

    • Very interested in trying this thing out! for those that have tried it,when you release them do you release in garden or grass? And do you risk killing them when you mow lawn?

      Also would they bite or anything when kids walk around in the grass?

      The Home Depot link posted here says they are "Tenodera aridifolia sinensis".

      Wikipedia says:

      The Chinese mantis (Tenodera sinensis) is a species of mantis native to Asia and the nearby islands. In 1896 this species was accidentally introduced by a nurseryperson at Mt. Airy near Philadelphia, United States. Tenodera sinensis often is erroneously referred to as Tenodera aridifolia sinensis

    • Praying mantis' will also eat honey bees, so keep this in mind if you have a lot of flowers. As much as I'd like to deal with other pests, I wouldn't want to harm bees.

      Wasps, aphids, mosquitoes and others can all F off.
