Putting the substrate in the oven might help, but it might also burn down your house. Boiling it will invite fungus and mold... running it through the dryer in a laundry bag will screw up your dryer. In short, I am sorry, but ya gotta chuck it.

Something else... I would look into Boric Acid. I know it isn't dangerous to mammals, but I have no idea about reptiles. It will kill any bug, though. Ask your local vet if you can use it around the snake. If so, mix a bit into the new substrate you get to prevent reinfestation.
No you really dont have to chuck it. They dont even know if the bugs came from the bark. Theyre all over the house and one happened to be in the tank. Secondly, You dont have to BOIL it, you can rinse it with water
