Abstract
Rodents are entrapped in hot melt adhesive which is disposed on a thermoformed thermoplastic base sheet which has a series of closely spaced ridges defining a rodent runway extending the length of the base sheet. The ridges create a series of depressed valleys which receive the adhesive and engage the quantity of adhesive with the base sheet to mechanically retain the adhesive against shifting off the base sheet. A substantially unobstructed expanse of adhesive without exposed ridges is presented on the runway for encounter by a rodent. Two stiffening ribs extend upwardly from the base sheet on either side of the runway to rigidify the base sheet. Multiple protrusions extend adjacent to each stiffening rib exterior to the runway. The protrusions are engaged on top and bottom by parallel projections of rack members within a papers or corrugated container such that multiple glue boards may be stored and dispensed.
