Nature House Spare-O-Door Sparrow TrapA easy and effective way to control sparrows that are causing trouble, the NHSD1 resembles a regular Trio door, but has a smaller entrance hole. This door can be easily installed in place of the regular Trio door, turning the room into a trap. Uses no bait - just sparrows' incessant search for nesting cavities. (The bait-type NHST1 Sparrow Trap is more effective in winter or in catching large numbers of young sparrows just out of the nest.) Martins and most other yard birds cannot enter. A red signal pops up to tell when the trap is occupied. Sparrows can be removed without opening the compartment: raising the entrance bar allows the sparrow to exit through a plastic tube and into a bag. |
