Costco selling praying mantis as insect control

Wow.. I can’t believe they are selling these things at Costco. Seems like a good price and beats using pesticide.

 

Praying Mantis Natural Insect Control Egg Case

 

Approximately 40 to 400 
Praying Mantis Eggs

$18.99

Item # 129014

Shipping & Handling included

 

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 in early fall and another egg case 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.)

Specifications:

  • Egg case dimensions (dia.):
    2.54 cm (1 in.)

  1. why doesn’t this say about location, climate? how do i know if these guys will survive winter if it does not say anything about climate?

  2. i ve been looking to purchase these for weeks, couldnt find any that sell in aus. please tell me how to purchase these eggs.
    thx heaps

  3. At the present time I have an egg sack that I expect to be hatching very soon. I am going to be selling them. Does any one know if there is any market for them to be sold after they hatch?

  4. I have concerns about my hummingbird population. I would like to either use ladybugs or mantis in my yard, but worry about harming the birds. Any ideas?

  5. I “hunt” mantis egg sacks every fall and usually find a plethora. If anyone is interested let me know. They should be sent sometime in the winter so they don’t hatch prior to releasing them into your garden or winery… Keep the sacs in a cold garage or just outside until danger of frost in over. If kept in a sunny window or a arm area they will hatch in the winter (you do not want this!) It is really, really cool to watch them hatch–they usuallly all come out within hours, and when they initially emerge they are embryo-like in appearance, but within moments they change into teeny little praying mantis.

  6. I live in Toronto Ontario. I picked up an egg sack – and as advertised, 4-6 weeks later I had several hundred of the little critters. I started the process in April, they hatched in mid-May and I put them outside.

    Low and behold – this last weekend (September 12) I found two in my backyard. One brown and one green… and boy are they awesome! They are each 5-6″ long, and extremely tame.

    Highly recommended!!!

  7. I just caught a huge praying mantus and she laid an egg sack last week and died. The egg sack is in my aquarium. Does anyone want to buy them?

  8. I live in Michigan and found a mantis egg sac attached to a stalk from one of my day lilies. The stalk has now turned brown and is almost resting on the ground. Should I bring the egg sac inside or leave it where it is?

  9. Staying just off the ground is fine. Laying on the ground could mean too much moisture. Best to leave outside. If you are worried about it you can cut the day lilly stem with sack attached, and place in a safe place. You can tie it to a branch or place in crook of tree

  10. I inadvertently brought in an egg sac that was attached to my Christmas tree. Unfortunately, it hatched in my livingroom this week, and so far I’ve killed 127 of the little nymphs. These things are all in the wild, why would anyone actually buy them???

  11. Check your local nursery for praying mantis eggs.
    We want them because they eat insects & we can avoid using pesticides.
