Shipping & Returns

Because we ship live insects and want them to arrive to you as freshly as possible, we only ship Monday through Wednesday. This means your shipment will arrive Tuesday through Thursday, possibly Friday if there are any unforeseen delays such as bad weather. Since FedEx does not ship over the weekend, we do not want insects to sit in a fulfillment center where they have a greater chance of not arriving to your garden fresh-as-can-be.
