*SHIPPING DETAILS* Due to the sensitive nature of live insects, we ship Monday, Tuesday, Wednesday, and Saturday in an insulated box with a temperature control pack. Live arrival is guaranteed; however, if your temperature is below 40F or above 80F, the box needs to be held for pick up at your local post office for the live arrival guarantee. Please indicate at checkout if you need the box held for pick up. We check the destination temperature for each order, and we will contact you if no note is left or message sent. This is a non-returnable item, but we guarantee live arrival as long as the above conditions are met. If there are any problems, please contact us. We want you to receive lively, healthy insects. Bioactive combo pack contains an 8oz deli container of mixed springtails on coco fiber, which contains hundreds of springtails, which are a random combination of several of the following springtail species (Folsomia Candida, Sinella Tropical, Sinella Curviseta Pink, Rutabaga Runners, Lepidocyrtus cinereus, Silvers, Pseudosinella Alba Prospectors), a container with 15 P. Pruinosus Powder Blue isopods, and a container of 20+ Dwarf Purple isopods. This clean-up crew is suitable for most bioactive enclosures.
