We ship Monday through Wednesday only to minimize the risk of the live animals being delayed in possible harsh weather conditions over the weekend. Depending on the current temperatures, shipping may occur on Saturday so the isopods/springtails travel during ideal weather conditions.

*For USPS, if your temperature is under 45F or above 80F, the box must be held for pick up at your local hub or post office for the live arrival guarantee.  Even if you will be home to receive the package, these are live animals and they cannot survive extreme temperatures in a hot or cold delivery vehicle all day.  If your temps are below 40F, it is unsafe to ship live animals, and the animals will not be shipped until the temperature is above 40F in your area. Live arrival guaranteed for the count purchased.  It does not include any extras that may be sent.  Please read full shipping policy.

Hold for pick up can be requested by typing HOLD in text box located near the "quantity" button or in the notes at checkout.  Your order will be held for pick up at your local post office.

*Supply only orders ship USPS Ground Advantage Monday through Friday.
