This nest box with round hole is what we will use for the simple installation instructions.

This sparrow trap will work on any nest box which has a flat wood front with round, oval, or slot entrances as shown in  photo above.  (Also works with side opening boxes)

Each sparrow trap comes with a template and a complete set of instructions for mounting in any of the different styles of nest boxes. Once you do one nest box, the next ones will go much easier.

Open nest box door and lay pattern on inside of door with edge marked “Top” towards the hole.

Holding pattern centered on door and about ¼ inch down from bottom of entrance hole, mark on cross hairs with an awl or sharp nail where the two screws are to go.

Slide sparrow trap on screws, set trap and gently close door.

When the sparrow enters, it will trip the trap and the orange dot will show (as shown in photo). 

When you set this sparrow trap or any other trap, you must monitor the nest box within 30 to 60 minutes.
