  • Patent number: 5301456
    Abstract: The invention relates to a portable luminous trap for flying or crawling insects. A fluorescent lamp in the center of an insect ingress zone attracts the insects. Transparent baffles radiating outwardly from the lamp act as walls and an insect hitting a baffle is stunned and drops downwardly, through a funnel opening into an entrapment container therebelow. The funnel also helps prevent escape of still-living insects from the container. An alkaline dry cell battery powers the lamp, test circuits for the battery and the lamp, and a clock circuit. A photocell is used to activate the trap at dusk and the setting for the clock circuit determines the length of time that the lamp is activated each night.
