Date of this Version The effectiveness and selectivity of
several traps and trap Modifications were field-evaluated and
compared in Alabama from 1977 to 19B0. No. 220 Conibear traps
placed in baited open-end boxes (TB) on the ground posed a
hazard to dogs and were not recommended for general use in
terrestrial sets. They may be effective to control feral dogs in
special situations or areas. TB devices attached to tree trunks
1 m above the ground eliminated the hazard to dogs, but rendered
the trap ineffective for taking small mammals. No. 220 Conibear
traps with selective position treadle triggers placed in trail
water-sets were significantly less effective for taking raccoon
and other small mammals than standard jaw traps. No. 120
Conibear TB baited with putrified deer meat or fresh fish were
found in field evaluations to take one opossum or raccoon per
8.4 trap nights and caused no mortality in dogs. Visitation at
trap sites by bobcats, dogs, foxes, ducks, and rabbits was
evidenced by numerous tracks, but n
