How do worms ship?
Worms are perishable and need some special handling. Worms are shipped on Monday/Tuesday by US Postal Service Priority Mail to ensure timely delivery. This way they are received on a week day making it less likely they will sit in a mail box or be left on a porch where they may be subject to sun, rain, heat and cold.
Worms are shipped in a breathable box with some bedding material and as long as they are not subject to extreme temperatures the worms will be fine in transit for a several days. Always advise the shipper if you need to delay the delivery of your worms. Their goal is to ensure a delivery of live healthy worms.
