When are you leaving for your trip? Choose overnight shipping from either http://www.entirelypets.com or http://www.pro-products.com.

Definitely order a can, whether it will get there in time or not - you're still going to need if. For immediate relief and to kill the mites currently on the snake, go to a pet store that carries reptiles and buy some Reptile Relief and wipe your snake down and treat the enclosure. This will kill the mites, not the eggs.

Then when you get back from your trip, and the P-A-M has arrived, treat the enclosure, and you should be rid of the mites and the eggs will be killed.

Reptile Relief will rid you of mites for about 30 days and then the eggs will start to hatch.
