As I am going to foster for some snakes that came from that place in Arlington, I will be quarantining them and taking the correct procedures so none of my established collection gets infected. No reptiles of my established collection will be in the same room as the quarantined reptiles.

The precautions I know of so far is:
Do everything last with the quarantined reptiles
-Spot cleaning
-Feeding
-Handling
-Changing water

Keep things sanitized
-Wash hands after handling
-Wash off the tongs I used for them with soap and then put in rubbing alcohol for a few minutes to kill any bacteria
-Keep area where quarantined reptiles are clean

Keeping reptiles away from the quarantined
-Bring no reptiles in the same room as the quarantined
-No interaction with established reptiles and quarantined reptiles

What other precautions should I take?
