Description
2 1 1~f~98 TITLE: FIRE ANT TRAP AND METHOD FOR ENTRAPPING FIRE ANTS
FIELD OF THE INVENTION
The present invention relates to a device and a method for attracting and ellll~pillg fire ants. More particularly, the present invention relates to adevice and a use of a device having prongs for penetrating the surface of a fireant mound. A subtle vibration is applied to the prongs for provoking the ants, 5 for urging them to climb the prongs and to creep into a container comlllullicating with the prongs wherein they can be en~ ed~
BACKGROUND OF THE INVENTION
Fire ants are common especially in the southern part of the United States. Fire ants live in the ground and build conspicuous mounds which can 10 expand to a height of nearly a foot or more and a diameter of several feet.
Such mounds cause extensive damage to lawns, parks, nature trails, pasturage, and landscape architectures.
Fire ants are known to climb in numbers the legs of a person standing nearby one of those mounds, and to attack their victim simultaneously, 15 injecting a venom which causes an intense burning pain. Fire ants are particularly dangerous to children, to adults allergic to the fire ant sting, tolivestock and to other small ~nim~l~
21 7~0q8 "' -Several types of devices have been developed in the past to entrap and exle.,.~ te fire ants. In a first example, U.S. Patent 2,168,339 issued on Aug.
8, 1939 to Curtis J. Himel, discloses an ant trap comprising a insecticide receptacle, a bait receptacle and a runway to the bait receptacle with a gap 5 over the insecticide receptacle. The insects trying to cross over the gap loose their grip and fall into the liquid insecticide.
A first inconvenient with this device is that the insecticide receptacle has an opened top whereby the chemical insecticide is accessible to birds, rodents and also to young infants left lln~ nded, when the device is installed I o near a playground for example.
In a more recent example, the U.S. Patent 5,325,626, issued on July 5, 1994 to Robert L. Jackson describes another device for eradicating fire ants using a chemical insecticide. The pesticide dispenser described therein includes a reservoir and a conduit that transports the liquid pesticide from the15 reservoir to a pointed tip. The tip is adapted to be pushed deep into an ant mound, for delivering the liquid insecticide directly into an entire fire ant colony.
However, recent awareness of the environmental dangers associated with these pesticides have severely limited their uses. In this respect many 20 chemical pesticides are not recommended for use near agricultural fields, fruit bushes and streams where the chemical products may enter a food chain.
Hence, the pesticide dispenser described therein is not always practical for controlling an infestation by flre ants in all geographic locations.
2 ~ ~oq8 -Another relevant device is described in the U.S. Patent 4,667,436 issued on May 26, 1987 to James A. Benson. This patent describes an apparatus powered by an electric altern~ting source, and a spike for insertion in an anthill. The device has an insulator and two wires wrapped about the insulator 5 forming a double helical coil. The two wires have a high voltage applied across them to electrocute fire ants upon contact.
Still a further type of device for ~xle~ ting fire ants is described in the U.S. Patent 5,400,543, issued on Mar. 28, 1995 to Dwane R. Ideker, Jr.
The apparatus for capturing and extennin~ting fire ants includes a container, 0 a vacuum unit and an inlet hose having a digging attachment to loosen a fire ant mound. The device is used for collecting the entire mound contents by suction, and for ~le~ tin~ the ants by asphyxiation inside the container.
Fire ant mounds are not always located near a source of electricity, and it may not always be applopliate to run an electric extension cord to the anthill 15 to operate a vacuum unit or the electrode of the prior art inventions described above. Therefore, electrical devices in general are disadvantaged for controlling an infest~tion by fire ants on a large property for example, or neara cottage where electricity is not available.
SUMMARY OF THE INVENTION
In the present invention, however, there is provided a fire ant trap having a stand comprising at least one prong for penetrating the surface of a fire ant mound, and for supporting the trap above the mound. The trap also comprises an actuator assembly mounted atop the stand.
21 75û~8 ~._ This actuator assembly has a stalk member connected to the prong at a first end thereof and extending into a stem-like member at a second end thereof. The actuator assembly also comprises a timer and a skiking means for re~ elllly impacting the stem member.
The fire ant trap of the present invention further comprises a container being supported by the actuator assembly, and having an opening encircling and enclosing a portion of the stem member.
During use of the fire ant trap, a vibration of the actuator assembly is transmitted through the prong for provoking the ants in the mound, and for inciting those ants to climb the prong and to creep onto the stem member.
Then, the abrupt ~h~king of the stem member dislodges the ants therefrom and causes them to fall into the container.
A first advantage of this aspect of the present invention is that the vibration of the actuator assembly transmitted through the prong irritates the ants and avails their natural defensive instinct to attract them into a container where they can be impetuously enll~ped.
In accordance to another aspect of the present invention, the timer of the actuator assembly is a mechanical clockwork. Thus the clockwork produces a subtle vibration to continuously provoke the ants in that mound.
Moreover, the fire ant trap of the present invention does not require electricity or chemical insecticide, and can operate lln~tten~ed for relatively long periods.
~ J ~98 In accordance to yet another aspect of the present invention, the container used therewith is a common plastic soft-drink container; a 2-litre bottle for example. A first advantage of using such container is that the insidesurface of these bottles is highly polished, m~king it hard for the ants to climb 5 back along its inside walls.
A second advantage for using a soft-drink container is that these bottles are readily available and are easily sealed off with their original caps to asphyxiate the ants trapped therein when an anthill has been cleaned out.
In accordance to a further aspect of the present invention, there is lo provided a novel method for enll~ping fire ants in a container. This new method comprises the steps of;
a) inserting a prong in a fire ant mound;
b) vibrating slightly the prong for provoking the ants in that mound and for defensively urging these ants to climb the prong;
15 c) encircling a portion of the prong in the container;
d) periodically ch~king that portion of the prong for dislodging the ants thererlolll, and for c~llcin~; these ants to fall into the container; and c) closing the container ell~ lg the ants thereinto.
Fire ants have a natural instinct of attacking an intruder in numbers.
20 Accordingly, this new method uses the natural instinct of the insects to attract them into a container where they can be el,llapped. An ;"~e""i~lent or a continuous subtle vibration tr~n.cmilted into the mound over a long period causes all ants in that mound to climb into the container or to move away.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to Figures 1, 2 and 3, there is illustrated a fire ant trap of the preferred embo(liment The fire ant trap of the preferred embodiment comprises broadly a stand 10, an actuator assembly 12 and a container 14.
The stand 10 preferably has the shape of a tripod with three prongs 16 each having an upper end joining one-another in a socket-like formation 18.
Each prong preferably also has a lower pointed end 17 which is adapted to penetrate the ground.
The actuator assembly 12 has a stalk member 20 connected to the socket formation 18 and ext~n(ling inside an inverted U-shaped tubular member 22, following a central axis of the tubular member 22, and into the container 14. The portion of the stalk member 20 extending towards and inside the container is a pointed stem member 24 having a smooth and slippery surface.
The tubular member 22 has an inside diameter substantially larger than the diameter of the stalk member 20 such that fire ants climbing on the stalk member 20 cannot reach the inside surface of the tubular member 22. The stalk member 20 is held inside the tubular member 22 by means of two spider-like spacers 30,32 as illustrated on Figure 3.
The tubular member 22 is opened at a first end thereof near the socket formation 18, and has a threaded opening 26 at a second end thereof for e~ g the threaded neck 28 of a suitable container 14. The container 14 is 21 7~J9~
preferably a soft-drink bottle type, such that it can be sealed off with a common soft-drink bottle cap and discarded with fire ants therein after use on the fire ant trap of the present invention.
The actuator assembly 12 also comprises a clockwork 34 for operating the stem-striking means, as will be explained later. The clockwork 34 is preferably a mechanical manual-type clockwork having a winding crank 36 and a dial wheel 38. The dial wheel 38 has a cylindrical boss 40 protruding axially from the front face thereof. The clockwork 34 may also have a thumb knob selector 42 for setting the rotational speed of the dial wheel 38 to a first lo or a second value.
The actuator assembly 12 may also optionally comprise a handle 44 for carrying the fire ant trap from place to place, and a flap 46 extending over theclockwork 34 for protecting it from rain and dew.
The tubular member 22 has, immediately above the threaded opening 26, a hollow protrusion 48 extending radially from the tubular member 22 towards the clockwork 34. A plunger 50 is movably mounted inside the hollow protrusion 48, and is connected to the dial wheel 38 by means of a string 52, a shackle 54 and a link member 56. The plunger is urged towards the base 23 of the pointed stem member 24 by a spring 58.
In use, the tripod stand 10 is set over a fire ant mound 60 as illustrated in Figure 1, with the prongs 16 penetrating the mound 60 to a depth which is sufficient to rigidly support the fire ant trap of the preferred embodiment, while the container 14 does not touch the mound 60. A suggested depth of the prongs 16 below the surface of the mound 60 is approximately between two to six inches.
2i 7~C9(~
The fire ant trap of the preferred embodiment is preferably sold with one or more sealed envelopes 62 cont~ining a composition made of a sticky substance and a fire ant bait, such as molasses and/or gear oil. This compo-sition is preferably poured into the container 14, as indicated by arrow 64 of 5 Figure 2.
The composition is also preferably spread over a major inside surface of the container 14 by working the container in several directions prior to installing in to the thread engagement 26 at the second end of the tubular member 22.
At that time, the clockwork 34 may be fully wound, and the actuator assembly 12 with the container 14 attached thereto may be mounted on the tripod stand 10 by placing a taper e~Lle~ Ly 68 of the stalk member 20 into the socket formation 18. The fire ant trap of the preferred embodiment is thereby ready for use for attracting and capturing fire ants in that anthill 60.
The operation of the clockwork 34 produces a light vibration which is transmitted through the prongs 16 and into the mound 60. Such a vibration, and the intermittent operation of the stem-striking means provokes the fire ants, urges them to climb the prongs 16 and to creep into the tubular member 22. Once the ants are inside the tubular member 22, the odour of the bait 20 inside the container 14 incites them to move further and to accumulate over the pointed stem member 24.
The rotation of the dial wheel 38 of the clockwork 34, in cooperation with the link member 56, the shackle 54 and string 52 causes the plunger 50 to periodically strike against the base 23 of the pointed stem member 24, to 25 dislodge the fire ants from the stem member 24, and to cause these ants to fall and stick to the bottom of the container 14.
2 1 7$Q9~
The operation described above is further enhanced when the prongs 16 and stalk member 20 have a dull-finished surface to provide a good adherence to the ants, and when the pointed stem member 24 has a highly polished and slippery surface. A smooth coating may also be applied over the stem member 5 24 to further increase its slipperiness, to dislodge thele~iolll a large number of ants at every blow of the plunger 50.
The inside surface of a soft drink container 14, as suggested herein, is also relatively smooth whereby the ants escaping the sticky composition, and attempting an ascension against the inside wall of the container 14 are also I o dislodged at every blow of the plunger 50. The tubular member 22 retaining the container 14 receives a reactive impact from the plunger 50 striking againstthe base 23 of the pointed stem member 24. Hence, both the container 14 and the pointed stem member 24 are shook periodically to dislodged the ants accumulating on the surfaces thereof.
When a quantity of ants are captured inside the container 14, and when there is no apparent activity in the mound 60 or near the prongs 16, the container 14 may be taken off the actuator assembly 12, and sealed offwith the original container cap to asphyxiate the enLl~ed ants. The container 14 may then be discarded or washed out for reuse on another anthill.
Referring now to Figures 4,5,6 and 7, there is illustrated the operation of the plunger 50. As said earlier, the movement of the plunger 50 inside the protrusion 48 is effected by means of a string 52, a shackle 54 and a link member 56 connected to the dial wheel 38, and of a spring 58 inside the protrusion 48. The spring 58 urges the plunger 50 against the base 23 of the pointed stem member 24.
2 1 7~0'~8 When the clockwork dial wheel 38 rotates in a clockwise direction, and when the connection 70 of the link member 56 to the dial wheel 38 is in a left side quadrant of the dial wheel 38, as illustrated on Figures 4 and 5, the link member 56 ~ reles with the boss 40, and is levered by boss 40 such that the 5 shackle 54 follows an arc about the axis of the dial wheel 38. This movement of shackle 54 pulls on the string 52 and on the plunger 50 to compress the spring 58.
As the dial wheel 38 continues to rotate under the action of the clockwork 34, the connection 70 of the link member 56 moves in a right hand lo quadrant of the dial wheel 38, as illustrated on Figures 6 and 7. When the connection 70 gets passed a longitudinal axis of the string 52, as seen on Figure 6, the link member 56 becomes in an unstable position. The force of the spring 58 causes the link member 56 to rotate about the connection 70 as illustrated on Figure 7, and to let the plunger 50 move precipil~tely, to strike15 against the base 23 of the pointed stem member 24.
The stalk member 20 and the pointed stem member 24 are held into the tubular member 22 by a first and second spider spacer 30,32 as explained earlier. The pointed stem member 24 is therefore unsupported in a region on interference with the axis of the plunger 50. The pointed stem member 24 is 20 thereby able to resonate vigorously under a striking of the plunger 50, to dislodge the ants which may have accllm~ ted on its surface. This movement is repeated according to the period of the dial wheel 38.
A clockwork 34 for use in the fire ant trap of the preferred embodiment has a winding duration of at least about ten to twelve hours, and preferably up 25 to twenty four hours or more. A rotation of the dial wheel 38 is preferably one 2 1 7~0~'3 turn at every thirty seconds to a period of thirty minutes or more. The clockwork 34 may also have a dual speed selector 42, as mentioned earlier to accommodate ~nthill~ of different populations.
It would become apparent to the person knowledgeable in the art, that 5 a longer winding duration, or a different stem-st~iking means may be employed without departing from the broad concept of the present invention. It would also become apparent to the person skilled in the art that the prongs may be replaced by alternate means for supporting the fire ant trap, and for trans-mitting a vibration into an ant mound, without affecting greatly the results 10 disclosed herein.
Accordingly, while the above description provides a full and complete disclosure of the preferred embodiment of this invention, various modifi-cations, ~ltçrn~te constructions and equivalents may be employed without departing from the true spirit and scope of the invention. Such changes might 15 involve alternate materials, components, structural arrangements, sizes, operational features or the like. Therefore, the above description and accom-panying illustrations should not be construed as limiting the scope of the invention which is defined by the appended claims.

In use, the tripod stand 10 is set over a fire ant mound 60 as illustrated in Figure 1, with the prongs 16 penetrating the mound 60 to a depth which is sufficient to rigidly support the fire ant trap of the preferred embodiment, while the container 14 does not touch the mound 60. A suggested depth of the prongs 16 below the surface of the mound 60 is approximately between two to six inches.
2i 7~C9(~
The fire ant trap of the preferred embodiment is preferably sold with one or more sealed envelopes 62 cont~ining a composition made of a sticky substance and a fire ant bait, such as molasses and/or gear oil. This compo-sition is preferably poured into the container 14, as indicated by arrow 64 of 5 Figure 2.
The composition is also preferably spread over a major inside surface of the container 14 by working the container in several directions prior to installing in to the thread engagement 26 at the second end of the tubular member 22.
At that time, the clockwork 34 may be fully wound, and the actuator assembly 12 with the container 14 attached thereto may be mounted on the tripod stand 10 by placing a taper e~Lle~ Ly 68 of the stalk member 20 into the socket formation 18. The fire ant trap of the preferred embodiment is thereby ready for use for attracting and capturing fire ants in that anthill 60.
The operation of the clockwork 34 produces a light vibration which is transmitted through the prongs 16 and into the mound 60. Such a vibration, and the intermittent operation of the stem-striking means provokes the fire ants, urges them to climb the prongs 16 and to creep into the tubular member 22. Once the ants are inside the tubular member 22, the odour of the bait 20 inside the container 14 incites them to move further and to accumulate over the pointed stem member 24.
The rotation of the dial wheel 38 of the clockwork 34, in cooperation with the link member 56, the shackle 54 and string 52 causes the plunger 50 to periodically strike against the base 23 of the pointed stem member 24, to 25 dislodge the fire ants from the stem member 24, and to cause these ants to fall and stick to the bottom of the container 14.
2 1 7$Q9~
The operation described above is further enhanced when the prongs 16 and stalk member 20 have a dull-finished surface to provide a good adherence to the ants, and when the pointed stem member 24 has a highly polished and slippery surface. A smooth coating may also be applied over the stem member 5 24 to further increase its slipperiness, to dislodge thele~iolll a large number of ants at every blow of the plunger 50.
The inside surface of a soft drink container 14, as suggested herein, is also relatively smooth whereby the ants escaping the sticky composition, and attempting an ascension against the inside wall of the container 14 are also I o dislodged at every blow of the plunger 50. The tubular member 22 retaining the container 14 receives a reactive impact from the plunger 50 striking againstthe base 23 of the pointed stem member 24. Hence, both the container 14 and the pointed stem member 24 are shook periodically to dislodged the ants accumulating on the surfaces thereof.
When a quantity of ants are captured inside the container 14, and when there is no apparent activity in the mound 60 or near the prongs 16, the container 14 may be taken off the actuator assembly 12, and sealed offwith the original container cap to asphyxiate the enLl~ed ants. The container 14 may then be discarded or washed out for reuse on another anthill.
Referring now to Figures 4,5,6 and 7, there is illustrated the operation of the plunger 50. As said earlier, the movement of the plunger 50 inside the protrusion 48 is effected by means of a string 52, a shackle 54 and a link member 56 connected to the dial wheel 38, and of a spring 58 inside the protrusion 48. The spring 58 urges the plunger 50 against the base 23 of the pointed stem member 24.
2 1 7~0'~8 When the clockwork dial wheel 38 rotates in a clockwise direction, and when the connection 70 of the link member 56 to the dial wheel 38 is in a left side quadrant of the dial wheel 38, as illustrated on Figures 4 and 5, the link member 56 ~ reles with the boss 40, and is levered by boss 40 such that the 5 shackle 54 follows an arc about the axis of the dial wheel 38. This movement of shackle 54 pulls on the string 52 and on the plunger 50 to compress the spring 58.
As the dial wheel 38 continues to rotate under the action of the clockwork 34, the connection 70 of the link member 56 moves in a right hand lo quadrant of the dial wheel 38, as illustrated on Figures 6 and 7. When the connection 70 gets passed a longitudinal axis of the string 52, as seen on Figure 6, the link member 56 becomes in an unstable position. The force of the spring 58 causes the link member 56 to rotate about the connection 70 as illustrated on Figure 7, and to let the plunger 50 move precipil~tely, to strike15 against the base 23 of the pointed stem member 24.
The stalk member 20 and the pointed stem member 24 are held into the tubular member 22 by a first and second spider spacer 30,32 as explained earlier. The pointed stem member 24 is therefore unsupported in a region on interference with the axis of the plunger 50. The pointed stem member 24 is 20 thereby able to resonate vigorously under a striking of the plunger 50, to dislodge the ants which may have accllm~ ted on its surface. This movement is repeated according to the period of the dial wheel 38.
A clockwork 34 for use in the fire ant trap of the preferred embodiment has a winding duration of at least about ten to twelve hours, and preferably up 25 to twenty four hours or more. A rotation of the dial wheel 38 is preferably one 2 1 7~0~'3 turn at every thirty seconds to a period of thirty minutes or more. The clockwork 34 may also have a dual speed selector 42, as mentioned earlier to accommodate ~nthill~ of different populations.
It would become apparent to the person knowledgeable in the art, that 5 a longer winding duration, or a different stem-st~iking means may be employed without departing from the broad concept of the present invention. It would also become apparent to the person skilled in the art that the prongs may be replaced by alternate means for supporting the fire ant trap, and for trans-mitting a vibration into an ant mound, without affecting greatly the results 10 disclosed herein.
Accordingly, while the above description provides a full and complete disclosure of the preferred embodiment of this invention, various modifi-cations, ~ltçrn~te constructions and equivalents may be employed without departing from the true spirit and scope of the invention. Such changes might 15 involve alternate materials, components, structural arrangements, sizes, operational features or the like. Therefore, the above description and accom-panying illustrations should not be construed as limiting the scope of the invention which is defined by the appended claims.
