I live in Wisconsin. With the weather being what it is, if I were to purchase Hyalella azteca from you would they arrive in good condition?

Hello, Thank you for the inquiry, Scuds can tolerate cold water as long as it doesn’t freeze solid. 72-Hour Heat Packs are the maximum duration available. Well insulated packing ‘stretches’ us up to 96 hours allowance for transit time of the Scuds. Priority Mail should deliver within 72 hours.
