An accessory for coil spring traps utilized in enhancing the spring strength of the trap and including a spring mounting frame capable of accommodating either one or two booster springs. The spring mounting frame includes a base bar with a pair of laterally spaced sleeves projecting therefrom for mounting reception over the normally extending free ends of the spring frame of a coil spring trap. The sleeves in turn mount auxiliary coil springs, the opposed projecting ends of which engage beneath the trap across member and one of the jaw manipulating follower plates.

In a two-spring trap having a pair of jaws, a U-shaped spring frame with a bight portion to one side of the jaws and a pair of opposed legs extending from the bight portion laterally toward the jaws, a follower plate pivotally mounted on each leg and engaged with the jaws, a single coil spring mounted on each leg between the follower plate and the bight portion and engaging the follower plate with a resilient biasing force, each leg including a portion extending beyond the follower plate a length substantially less than the length of leg receiving the coil spring; the improvement comprising means for increasing extension of said legs beyond the follower plates, said means comprising a pair of spring mounting members, each spring mounting member being elongated and including a tubular open end portion telescopically receivable over the extending portion of one of said legs of the spring frame, and a pair of second coil springs, each mountable on one of the spring mounting members for biasing engagement with a follower plate, each second coil spring including a first laterally extending tensioning leg engageable with a follower plate for enhancing the biasing force thereon, and a second laterally extending spring stabilizing leg engageable with a fixed portion of the trap.
