Folding crow trap. Double side entry design for crows rooks. Easily folded for storage after use to save space. Supplied with instructions and plastic ties to secure trap in built up form.

The crow trap has three compartments, one slightly larger than the others, and this larger compartment the decoy crow is usually kept in this must be large enough for the crow to stretch its wings. The other two catching compartments have spring loaded doors which are held open by split perches. When the decoy crow attracts the other crows they step on the perch which gives way under their weight and the door is sprung closed entrapping the crow in the trap. The traps can often be baited with eggs or egg shells placed on top or inside the compartments, although in the case of crows it is the presence of an intruder (ie. the decoy bird) which attracts them.

In the UK it is illegal to use a larsen or crow trap to catch other bird species

Any suitable bait such as meat scraps, small dead animals, offal, etc., may be used to bring crows into a given area. The importance of choosing a proper bait location and the use of baits for several days prior to the actual setting of the trap cannot be stressed too highly. Best results will be obtained if the trap has a "weathered" or old appearance, as crows are suspicious of shiny material. Ascertain the best place for positioning the trap, preferably where crows congregate or near their flyway. Place bait in a suitable location. Large bones, fat, dead rabbits or any frozen carcasses and offal may be used as bait.

Place the trap in close proximity to the bait allowing birds to become accustomed to the trap. Leave bait and trap with the catching doors tied back for one or two days until crows accept the bait. Small amounts of bait should be placed in the entrance to entice crows to enter. A daily check should be made near evening and any trapped birds disposed of humanely out of sight of the call bird. If trapping is successful, one or two live crows may be left in trap overnight to act as decoys, these decoys must be well cared for. If, after several days, no results are obtained, the trap should be moved to a new location and repeated.
