An insect trap using attractant light, comprising a source of light and a housing can be mounted on a vertical surface or placed near a ceiling surface. The housing and the source of light cooperate to form an upwardly facing opening for the facilitated entry of flying insect pests and for the reflection of light onto the vertical surface. Insects that enter the trap are immobilized on a surface within the trap. Cooperation between direct radiant light, reflected light and an upwardly facing entrance for insects substantially increase capture rates.

A housing has a first, dispensing end and a second, opposite end. A lever is squeezed against the housing to move a plunger toward the dispensing end. When fully squeezed, the lever extends parallel to the plunger and the longitudinal axis of the housing. The extent to which the plunger advances may be adjusted by relocating the pivot axis defined between the lever and the housing. A resilient washer is mounted on the shaft of the plunger and disposed behind a shoulder on the housing. The resilient washer deflects and/or stretches forward when the plunger advances, and urges the plunger rearward upon release of the lever.

A rodent bait station includes an enclosure having an inclined passageway leading from an opening in the enclosure to an elevated bait receptacle having a removable tray with a handle. The inclined passageway terminates at the lowest elevation of the opening to prevent water from becoming trapped in the enclosure. A separate internal receptacle is provided in the enclosure for storing and protecting printed materials, e. g. , maintenance records. A replaceable latch on the enclosure includes an alignment member disposed between a pair of engagement members which engage cooperative slots and which are deformable to unengaged positions by a key that wedges between the engagement members and the alignment member.
