Abstract
An improved rodent trap for use where sanitary conditions are required. The trap housing includes a rodent activated trip mechanism which dislodges a door prop causing the spring or weight biased door to latch shut trapping the rodent inside. Air seals are provided around the door so the rodent is caused to suffocate. A transparent inspection panel, which may be the door, is provided for allowing the user to determine whether the trapped rodent is still alive.
