Abstract
An insect toxic bait dispenser has a top with multiple downwardly opening compartments in which toxic bait fluids may be retained by an underlying foil barrier. The top is supported on a base with posts positioned beneath the barrier. Base prongs extend into a top shaft with ledges at different heights, preventing part separation when the barrier is intact above the posts, and, when the top is closed on the base, piercing the foil seal and dispensing liquids into fluid retaining members held in base pockets. To use, a peripheral tear strip is removed from the base, permitting the top to descend on the base causing the posts to puncture the seal, compressing the fluid retaining members against the barrier to receive and dispense toxic bait liquid while retarding the rate of liquid evaporation. The top may be hinged to the base, or urged downwardly by a threaded cap.
