With an "industrious" back yard and a large vacant field behind the neighbors across the street we occasionally find an opossum nesting somewhere we can usually catch with a gloved hand. Yesterday I spotted a juvenile running across the street, I gave chase but it hid in the neighbors garage and I lost track of it after a few minutes.
Figured it mustn't be difficult or complicated and came up with this after having seen a couple of other traps before.
