Question

Does anyone know when ladybirds go into hibernation?

Answer 1

Not exactly, but what I do know is when I try to buy them in early spring, reputable collectors will not have them in March , April, and May, because they are still somewhere in California buried under the snow.

If you dig them out before they are ready, the LadyBirds left behind will freeze to death.

   So my guess is from the end of October to May 15 or so.

Best I can do as a distributor of Beneficial insects in the United States.
