Same for most of the rest of the apartment, really. Give the hunters what they're looking for, and they won't dig deeper.

Gabriel ventures to the doorway so he could watch his brother. "You may want to watch out for surprises. Left one or two for hunters. Not enough to kill them, but enough to make 'em jump and swear a blue streak."

A case in point being the drawer that was in the process of being opened with the very real looking viper striking at his brother's hand but not actually leaving damage.
