EASY, (very effective) 10 minute SPARROW TRAP - Steve Gruenke
Using a cordless screwdriver:
Use where a house sparrow has already invaded a nest box.
A. 1" screw inserted until almost tight (plate part B must be able to
swing down parallel to box)
B. 1" X 4" metal plate.
C. Entrance hole to nest box.
D. 1 ½ " screw, top of screw extend upward on a 45 degree angle, and
extend screw head outward about ¾ "
D. Thumbtack attached with thin fishing line. Set quite loosely!! But just
enough to keep plate up
E. Clear, thin fishing line, extend to the bottom, back of nest box, secure
tightly at bottom/back with another thumb tack.
Notes: Do NOT use this trapping method unless a house sparrow has already
invaded and began nesting in the nest box. If the sparrow is actively entering
this nest box, this method will trap them quickly (usually 10 minutes to 1
hour). Once the sparrow enters, and trips the line, (as long as it is set
correctly) the thumb tack will easily be removed, and the metal plate will rest
in the crevice of screw (D), covering the entrance hole. Then secure the plate
with duct tape, a tack or a screw, so that it cannot flap out. Remove the nest
box (screws) from its pole. Take entire box, and place in bucket of water. You
do not want to attempt to catch the house sparrow, it'll get away. This method
will also re-clean the nest box for bluebirds or other native cavity nesters.
After this process is complete, remove screws, plate, tacks and fishing line,
and reattach nest box to pole. It is the most effective method of sparrow
control that I have found so far.
