We have very specific temp guidelines at our site, I will link the FAQ below.

We go by the daytime high in both origin and destination. If the daytime high in either location is between 70F and 91F, do NOT use a heat pack.

Nighttime temps, hub temps, everything else is relative. We have shipped hundreds of thousands of packages with our temp guidelines with outstanding success. The most common cause of DOAs in live reptile shipments is actually the mis-use of heat packs, either using them when you don't need them, using more than one, or using heat packs of less than 40 hour duration.

Reptiles can withstand cool temperatures much better than they can withstand hot temps.

Check out our FAQ on regulating the temperature of your package for full temp guidelines, summer and winter, including heat pack use. https://www.shipyourreptiles.com/en/...ds#question-15
