This leaves trapping and baiting the best options to remove excessive populations that can destroy property and crops. Population reduction is by far the best option to reduce damage and loss from sparrows. There is a lot of public opposition to this method of sparrow control due mostly to the general population’s understanding of the facts of life. Excessive populations of sparrows results in econimic and health losses. Unfortunately, the EPA under public influence, has made it prohibitively costly for businesses to research and produce new products to help reduce the population safely. Fortunately there are a number of tried and true methods of trapping and baiting sparrows that have worked well for generations.
Traps with a V-top entrance are excellent for trapping sparrows as well as starlings and grackles. Once set up, you should be able to attract and capture hundreds of birds. These traps work best when placed in a location where the birds gather on level ground. Just bait and wait. Birds fly into the bottom of the V top and cannot figure out how to fly back out as they tend to fly up to the highest point. Only the bottom of the V is open. Because the bottom of the V is not close to the floor, birds have a difficult time learning how to escape. As with all traps, be certain to remove the birds regularly as sparrows are quick learners and may eventually figure out how the trap functions. See it at WCS V Bird Trap.
Other cage type traps can also be effective for smaller bird populations. Avoid traps that must be constantly reset. Look for traps with multiple entrances and easy removal doors. Select a trap that will capture enough birds to solve your problems in a relatively short amount of time. If you have multiple problem areas, purchase enough traps to cover all areas. These cage types and other traps can be seen here.
Much of our discussion has focused around outdoor sparrow control. For interior sparrow and small bird capture, a mist net is recommended. The netting should be very fine, yet strong enough so birds cannot escape or harm themselves. A mist net may require a special permit. Non target birds that are captured must be released promptly.
