With powered doors and a wire trigger, even larger animals are being taken in the shortest double door traps available. Though not recommended for raccoons, 18 inch double door traps with a 9×11 opening take raccoons with regularity. Above is a 15 pound ‘coon in the 18 inch trap taken by Tim in Ohio.
Likewise, the 24 inch double door traps easily take armadillos as Dusty in Arkansas found out. Armadillos also have been caught in 18 inch traps on accession, again not the recommended size. The 24 inch traps have replaced traps that were 36 to 48 inches in length, making setting easier and faster, while allowing the shorter traps to be placed where the larger traps would not fit.
