  • mantis egg sacks never hatched

    Hi,

    I purchased 3 egg sacks, they have not hatched yet. I purchased back in April. How long does it take?

    Hello from Planet Natural –

    Praying Mantis egg cases can take 6-8 weeks of warm temperatures, 65-75 degrees daytime, no lower than 45 degrees at night, to hatch. I show that we shipped on —- and recommend that you give them some more time. It is rare when an egg case does NOT hatch. Please be patient!

    To speed up the hatch, we recommend placing egg cases — still in the bag — on top of a refrigerator, or some place that is consistently warm, but not hot. Do not place them on a windowsill as temperatures fluctuate too much.

    Note: Tiny praying mantis nymphs will emerge through the narrow slits of the egg case. Unless you can find the small nymphs (1/8 inch), it is impossible to tell if the egg cases have actually hatched — the egg case will NOT change in appearance.

    If there’s no sign of the nymphs after 6-8 weeks, please feel free to contact us. Here is a link to our website for more information on praying mantis:https://www.planetnatural.com/product/praying-mantis-egg-cases/.

    Thank you,
