Shipping live animals always involves some degree of risk that the animal will encounter
less than ideal conditions, and that risk can increase dramatically when the
temperatures are significantly higher or lower than what the particular animal needs.
Having knowledge of the particular species you are shipping is paramount, as different
animals require different considerations - so KNOW YOUR ANIMAL!
But generally speaking, the guidelines below can help you make informed decisions when
shipping most reptiles and amphibians in certain temperature ranges. IMPORTANT - when we use the term "heat packs", we are talking about heat packs that are designed for shipping live animals (like the ones we sell)! Do NOT use the "hand warmer" heat pack products found in sporting goods stores - they are NOT designed for shipping live animals and can get TOO HOT and actually prove deadly to your precious cargo! Also, when using the Cryopak Phase 22 packs (which are GREAT for shipping!), we do recommend putting them in a ziplock bag (in rare cases they have been known to leak a bit).
General Temperature Guidelines
Below 40°F- In weather this cold we recommend you consider not shipping
at all, and wait for warmer weather if possible. If you MUST ship in weather this cold,
use heat packs!
40°-70°F - Some type of temperature regulation is strongly suggested. If
temps are expected to be towards the LOWER end of this range throughout transit, a heat
pack (40 hour or longer) may be a good choice for most animals. If temps will be more
towards the middle or upper end of this - range or are expected to fluctuate within the
range (e.g. shipping from a cold area to a warmer destination) - a true heat pack may be
too much for some animals (some sensitive animals (crested geckos, some chameleons, etc)
do not fare well above 75 degrees, so if it's 60 degrees outside, a true heat pack in a
7x7x7 box will probably get too hot). In a case like this, a warm Cryopak Phase 22 is a
great choice as it can help keep the temp inside your box moderately warm without
getting too hot. Place a Phase 22 pack in boiling water for about 2 minutes, carefully
remove (with tongs!), and let it sit at least 3 minutes before putting it in the box. In
temps below 72 degrees, it will gently release it's heat energy inside your box as the
pack undergoes "phase change" from liquid to solid, thereby keeping the contents of the
box slightly warmer, without getting too hot like a true heat pack might do.
70°-85°F- Phase 22 packs are also good in this range. Cool them down
(place in freezer for a few hours (or fridge overnight), then wrap with a cloth or paper
towel before putting it in your box. It will gently absorb heat, and help keep the
inside of your box a nice low to mid 70's temp.
85°-95°F- Phase 22's are again highly recommended. Cool the packs down
place in freezer for a few hours (or fridge overnight), then wrap with a cloth or paper
towel before putting it in your box. They will gently absorb heat as they change from
solid back to liquid, and help keep the inside of your box closer to a mid 70's temp. If
you're certain your box will be in the upper end of this range for the entire trip, use
multiple packs, and maybe a Thermafreeze Cold Cell as well.
Above 95°F - In weather this warm we recommend you consider not shipping
at all, and wait for cooler weather if possible. If you MUST ship when the shipment will
be exposed to temps above 95°F, you MUST use cold packs! We also strongly recommend you
ship HAL (Hold At Location) to a FedEx ship center for pick up.
These are only general temperature guidelines. You should always
consider specific temperature needs of the species you plan to ship, the
temperatures in the shipment origin location, and temperatures in the shipment
destination location and adjust packaging as needed.
