Abstract
An insect controlling device and method which provides an environment within foraminous barrier to which at least certain fertilized female insects will be attracted to deposit their eggs, and in the barrier assuring wasting of the thus deposited insect eggs. The barrier may take a number of different forms for selectively controlling various species of insects, such as fruit flies, house flies, mosquitos and the like. The barrier may serve the dual function of insect control and predatory creature food supply, such as a bird feeder, fish feeder, or the like. For mosquito control the barrier prevents hatched mosquito larva or mosquitos from escaping a body of water in which the mosquitos may incubate.
Claims15
An insect controlling device comprising:
- an insect barrier adapted to intervene between an insect infested environment and an insect incubatory medium attractive to at least a certain species of fertilized female insects from said infested environment;
- said barrier having hole means therethrough small enough to preclude any adult insects or developed larva from escaping from inside said hole means;
- said hole means being only large enough to receive therethrough from outside of said barrier insect eggs, or tiny newly hatched larva attracted to said medium, and the small size of the hole means assuring that developed larva and insects maturing from the larva from will be trapped inside said barrier against leaving said barrier to enter said environment;
- said device comprising a bird feeder wherein said barrier comprises a perforate insect incubatory medium bait cage, and a trap chamber accessible by migration from within said cage to larva or insects maturing from the larva, and means affording access into said trap chamber of bird bills for capturing insects in said trap chamber but precluding insect or larva escape from the trap chamber.

An insect controlling device comprising:
- an insect barrier adapted to intervene between an insect infested environment and an insect incubatory medium attractive to at least a certain species of fertilized female insects from said infested environment;
- and said barrier having hole means therethrough small enough to preclude any adult insects or developed larva from escaping from inside said barrier through said hole means;
- said hole means being only large enough to receive therethrough from outside of said barrier insect eggs, or tiny newly hatched larva attracted to said medium, and the small size of the hole means assuring that developed larva and insects maturing from the larva will be trapped inside said barrier against leaving said barrier to enter said environment;
- said device being in the form of a fish feeder, comprising a platform providing a downwardly opening chamber and float means for supporting the platform on a body of fish-containing water, and said insect barrier being mounted on said platform and having passage means for migration of larva or insects maturing from larva into a chamber under said platform to serve as fish food.

An insect controlling device comprising:
- an insect barrier adapted to intervene between an insect infested environment and an insect incubatory medium attractive to at least a certain species of fertilized female insects from said infested environment;
- said barrier having hole means therethrough small enough to preclude any adult insects or developed larva from escaping from inside said barrier through said hole means;
- said hole means being only large enough to receive therethrough from outside of said barrier insect eggs, or tiny newly hatched larva attracted to said medium, and the small size of the hole means assuring that developed larva and insects maturing from the larva will be trapped inside said barrier against leaving said barrier to enter said environment;
- said barrier comprising a panel adapted to float on a body of water comprising the insecting incubatory medium and attractive to mosquitos, said panel having water pool depressing funneling toward holes in the bottoms of the depressions.
1 more element
A method of controlling insects, comprising:
- intervening an insect barrier between an insect infested environment and an insect incubatory medium attractive to at least a certain species of fertilized female insects from said insect infested environment;
- receiving from outside said barrier eggs from said female insects or tiny newly hatched larva through hole means in said insect barrier small enough to preclude an adult insect or developed larva from escaping from inside said barrier through the hole means;
- trapping within said barrier and against entering said environment any developed larva or insects maturing from the larva;
- providing said barrier in the form of a bird feeder having a perforate insect incubatory medium bait cage, providing a trap chamber accessible by migration from within said cage to larva or insects maturing from the larva, and affording access into said trap chamber of bird bills for capturing insects in said trap chamber but precluding insect or larva escape from said trap chamber.
1 more element
A method of mosquito control, which comprises:
- providing a foraminous floatable barrier panel having openings therethrough through which a female mosquito can deposit eggs but which openings are too small to permit a mature mosquito to pass therethrough;
- placing said panel in floating relation on a body of water confined within a receptacle having walls conforming to the edges of the panel so that a mosquito cannot escape around the edge of the panel;
- and locating the mosquito trap thus provided in an environment where female mosquitos are attracted to the water through the openings in the panel to deposit their eggs so that larva will develop in the water under the panel and thereby trapping and drowning mosquitos which may mature, by preventing escape thereof from said body of water through said barrier.
