Moving snakes cross-country

[Family Jewels]

Though, I'm not with USARK anyways, so I really can't even if I wanted to.

I think you mean you're not FedEx certified to ship reptiles... USARK is a lobbying group and has nothing to do with shipping (unless I've missed something?). Becoming FedEx certified through ShipYourReptiles.com is pretty simple, and two snakes will be pretty cheap to ship. You don't even technically need to be certified, but it makes the process much easier and cheaper too.

Anyway, I found this comment from someone planning to drive snakes across the Canadian border:

"To do everything legal you'll need the following;

US Import/Export Permit
US Exemption to Designated Port Permit

Once that is in place you can setup your US Fish & Wildlife inspection at the border. You'll need to book this 72 hours in advance and have all proper paperwork in order. Mainly your 3-177 properly filled out and a receipt listing the common and latin names, quantities of animals as well as $$ amounts.

Once your US Fish & Wildlife inspection is complete you can head off to Canada Customs, declare your animals and pay your tax."

I think your first step is to contact US Fish and Wildlife and ask them for specific instructions for driving through Canada to Alaska. Since the origin and destination for your snakes are both US soil, BUT you're going through Canada, US Fish and Wildlife will be able to tell you exactly what permits you will need, and they can help you contact the corresponding Canadian agency if necessary.

If the permits and legal process is a little overwhelming, it might ultimately be worth it just to get FedEx certified and ship directly to Alaska, you won't need any permits to do that.

If you choose to drive with them and figure out the legal aspects, just put them in secure reptile bags and place those bags in ventilated but insulated boxes. In each box, use a (semi-insulated) reptile heat pack to keep the box warm. If you switch out a new heat pack every 24-36 hours they should be fine. Some of the packs are supposed to last 40-70 hours, but you'll want to check them periodically to make sure.
