Definitions
- the present invention relates to electronic devices for trapping flies and other insects.
- Prior art electrocution devices have various drawbacks. For those that require high voltages, the carrying grid must be protected by an outside protective grill with small spacings so as to prevent the insertion of fingers and other objects. This limits the amount of U.V. light available to attract flies. Also, the grills in such devices are often equipped with relatively expensive automatic power log-out devices to avoid inadvertent (or intentional) contact should they be opened or tampered with. Moreover, when an electrocuted insect dies there can be a crackling sound that is disruptive to conversation or other nearby activities.
- Electrical wires or grids capable of stunning insects have also been used to retain crawling insects such as cockroaches within open-topped cages or aquariums to keep them from crawling up the side and out of the enclosure.
- the invention provides an electronic insect trapping device suitable to be linked to an electricity supply.
- An external housing has a cavity therein, an opening through one face, and a throat below the cavity.
- This is preferably a source of light (preferably U.V. light) for providing the light in the cavity.
- a first electrically conductive structure for incapacitating insects such as by stunning them is positioned within the cavity and is connectable to the electricity supply.
- a second electrically conductive structure is positioned adjacent the throat and is also connectable to the electricity supply.
- the second electrically conductive structure retains the insects within the container.
- the throat comprises two sloped walls which are separated by a narrow gap.
- the second electrically conductive structure comprises a plurality of electronic grids, at least one being positioned on one such wall and another being positioned on an opposed such wall.
- the throat thus creates a narrow passageway between the cavity and the container which preferably has a size (across the gap) of less than about one-half inch (1.27 centimeters - "cm") .
- the throat and second electrically conductive structure thus cooperate to retain the insects within the container.
- the container is a bag (e.g. a plastic garbage bag) having an upper-end that can be easily mounted onto a lower housing flange.
- the bag is positioned so as to receive insects that fall down through the throat.
- the first conductive structure may be omitted.
- the interior of the cavity may be coated with a slippery material such as oil, grease, silicone oil and the like to cause the insects to fall down the cavity and into the container where they are trapped.
- the first electrically conductive structure can have projections which extend into the cavity (e.g. round wires having a diameter of between 0.05 inches and 0.125 inches (0.127 cm and 0.318 cm)) .
- U.V. ultra violet
- the trap is configured such that the U.V. light attracts insects into the cavity.
- the first electrically conductive structure stuns, but usually does not kill the insects.
- the insects fall down through the throat to the bag.
- the second electrically conductive structure inhibits the insects from escaping from the container up through the throat as the throat is essentially surrounded by continuously active stun zones.
- insect pests can be trapped and accumulated for disposal with the device of the present invention. They include house flies (a general nuisance, spread disease in homes and food preparation areas, and spot eggs in poultry farms), horse flies, horn flies, face flies (spread disease in cattle), soldier flies, flesh flies, cluster flies, darkling beetles (damage wood and other structures housing poultry) and so forth.
- house flies a general nuisance, spread disease in homes and food preparation areas, and spot eggs in poultry farms
- horse flies horn flies
- face flies spread disease in cattle
- soldier flies flesh flies
- cluster flies darkling beetles (damage wood and other structures housing poultry) and so forth.
- the present invention works without high voltage electrocution of insects. It thus has the advantages of the 4,959,923 system. However, the present system has a much larger capacity and fly paper is no longer needed.
- insects surviving the fall into the bag and seeking to escape up the throat face the second power grid.
- the small size of the throat leads insects to try to land on the second grid (and then walk up the throat) . This re-stuns the insects. This continues until the insects no longer have any more desire or energy to try to escape. The insects will then starve (or suffocate) and die. Given the relatively large size of the bag, the system needs much less frequent maintenance.
- the flies are provided with sufficient room to fall down through the throat and normally not clog the throat. Yet, insects are unable to readily escape. Surprisingly, there is a size range where there is enough room for the insects to fall down but not so much as to let insects easily avoid the second stun grid.
- the objects of the present invention therefore include providing:
- a device for trapping insects, especially flying insects, of the above kind which is relatively silent in operation and can be used in areas which have very high population of insects;
- a device for trapping insects, especially flying insects, of the above kind which reduces the need for frequent maintenance and eliminates the need for an adhesive or sticky paper such as fly paper;
- Fig. 1 is a perspective view of a fly trap of the present invention, with its front face plate removed and with certain portions broken away;
- Fig. 2 is a perspective view of the front face plate
- Fig 3 is a schematic sectional view of the present invention n which a bag has been mounted on the lower portion of the Fig. 1 housing and the front face plate of Fig. 2 has been positioned adjacent the front of the housing.
- an external housing (generally 10) having an internal cavity 11, an opening 12 through a face thereof, and a throat 13 below the cavity 11.
- At least one source of U.V. light 14 connected to the housing 10 (e.g. three fifteen watt U.V. lamps) . These are preferably positioned in a box 15 past the housing 10.
- the front of the box 15 is a panel 27 which is a clear acrylic plastic that transmits U.V. light into the internal cavity.
- the U.V. light is also visible through slots 19 of front panel 18 when the panel 18 is mounted on the front of the housing 10.
- first electrically conductive wire grid 17 which is mounted in front of panel 27. It can be suspended from the top or sides of the housing (not shown) .
- the grid is preferably provided with 36 volt alternating current ("A.C") pulses of power through round stainless steel wires 17 which are .093 inch (0.236 cm) (or alternatively between 0.05 and 0.125 inches (0.127 and 0.318 cm)) .
- the wires are alternatively negatively and positively charged and are provided with pulses of electricity as described in U.S. patent 4,696,126 or 4,959,923 which is hereby incorporated by reference to teach such grids and the method of their operation.
- the round shape of the wires allows the flies to grip (and thus have more contact with) the grid. This provides a stronger stun disorientation for a given voltage.
- the grid preferably has five seconds for a cycle of which one second is on and four seconds are off.
- Throat 13 is funnel shaped 21 at its upper end (as best shown in Fig. 3) .
- the second electrically conductive structure 22 Adjacent the throat is the second electrically conductive structure 22. As shown in Fig. 3 it can be connected to an electrical supply 24 (note also that the electrical supply 24 can be connected to the U.V. light source via wire 25 or otherwise) .
- 110/120 volt/60 hertz, or alternatively, 220/240 volt/50 hertz current can be supplied for the three uses.
- One line from the supply can connect to conventional transformers and starters for the U.V. bulbs.
- a second line can feed a circuit board that transforms the power into 36 volts/300-360 hertz that are pulsed as described above.
- a third line can feed a transformer (or transforming circuit board) to yield continuous 14 to 36 volts A.C. at 50 or 60 hertz
- Another alternative is to have batteries provide the power with suitable transformers.
- container (bag) 28 having an internal void for collecting insects that fall through the throat.
- the second electrically conductive structure 22 is preferably two sets of printed circuit grids. Each of the grids containing four horizontally disposed lines 22A. The lines can be soldered electrical strips on a printed circuit board which carries either a negative or positive charge.
- the voltage at the throat can be set at 14 to 36 volts A.C. at 50 or 50 hertz. This is sufficient to prevent most insects that enter the bag from leaving it once they have fallen through the throat.
- the restriction at the throat is an important aspect of the invention. If the restriction is too large, insects such as flies can readily escape. Note that once flies are in the bag they are not only motivated to leave the bag to find food, they are somewhat attracted to try to leave back out through the throat due to the U.V. light n cavity 11. Thus, it is very important that the throat not be too large.
- the throat is too narrow it can clog with larger insects (e.g. moths) .
- larger insects e.g. moths
- the range of above about an eighth of an inch (0.318 cm) to about one-half inch (1.27 cm) is a range where most common flying insect pests normally drop freely through without clogging, yet do not readily escape.
- Those skilled in the art will be able to readily determine the appropriate throat size to cooperate with the electrically conductive grid used to retain the insects of interest within the container.
- Panel 18 is assembled onto the housing 10 and the power supply is connected to electricity so that the grids are activated (as is the U.V. light) .
- An insect attracted through openings 19 would enter the cavity and be attracted towards the transparent wall 27.
- Upon contacting two adjacent wires 16 a sufficient charge goes through the insects as to stun them (but not kill them) . They would then drop through the funnel and then bounce or fall through the throat into the bag 28. When they recover sufficiently to try to escape, the continuously active grid 22 re-stuns them.
- the bag can be removed and emptied (e.g.
- the invention m a poultry house. After 14 days of operation a fifty-five gallon (208 liter) garbage bag (which was the attached container) had been more than half filled with trapped insects.
- 208 liter fifty-five gallon
- the throat could be formed m a cylindrical shape (rather than by two walls) .
- the U.V. light source need not be m a separate box.
- a hinge 31 can be provided on panel 27 so that the panel can swing forward so that the U.V. bulbs 14 can be changed from the front of the device.
- U.V. light is the preferred attractant
- other attractants might also be used.
- other lights or known chemical attractants e.g. pheromones
- various types of collection containers can be used instead of a bag (e.g. boxes) .
- a suitable attractant such as a pheromone or U.V. light, for the trapping of insects, with or without a grid to stun the insects, for example, to trap darkling beetles, which along with flies, present a significant insect pest nuisance m poultry houses.
