Flying Insect Trap

Abstract

The present invention provides a flying insect trap employing a scent-based insect bait to attract flying insects to the trap. Insects can enter the trap through entry pipes in the side of the trap which curve or angle downward once inside the trap. A window of clear plastic or similar material is provided in the top surface of the trap to admit sunlight and draw insects seeking to escape upward and away from the entry pipes. If the entry pipes are made of a dark, opaque material, relatively little sunlight will enter the trap through the entry pipes compared with the clear plastic window, and insects within the trap will not perceive the entry pipes as a possible exit. The trap can be constructed within a removable top cap so that the trap can be supplied with dry insect bait which can be activated before deployment by removing the cap and adding water to the dry bait.

DETAILED DESCRIPTION

[0020] As illustrated in the accompanying figures, the insect trap (10) of the present invention features an enclosure (20), which will typically be constructed in a generally cylindrical shape, although other shapes are certainly possible and may be desirable for certain applications. In the embodiment shown in FIGS. 1 to 3, the enclosure (20) has an open top surface which is covered and sealed by a top cap (30), which is designed to be removable from the enclosure (20). Although not directly visible in FIGS. 1 to 3, the top cap (30) may include a window (40) which is transparent or translucent.

[0021] The side walls of the enclosure (20) have one or more apertures (50), with an entry pipe (60) inserted through each aperture (50). While the overall dimensions and proportions of these features may vary depending on the application to which the invention is put, a common arrangement, as shown in FIGS. 1 to 3, will have the apertures (50) and entry pipes (60) located at a position which is near the mid-point along the length of the side walls of the enclosure (20).

[0022] As seen in FIG. 2, each entry pipe (60) will have an outer opening (70) of a size to allow an insect of the kind targeted by the insect trap (10) to enter the entry pipe (60). The apertures (50), entry pipes (60), and outer openings (70) would typically be constructed with a generally circular cross-section, as shown in FIG. 2, primarily for ease of manufacture. The functions and advantages of the present invention do not necessarily depend on the circular or cylindrical shape of these elements, however, and those skilled in the art will recognize that other shapes could be used where desired.

[0023] As seen in FIG. 3, each entry pipe (60) will have an inner opening (80) located within the enclosure (20). The overall shape and dimensions of the entry pipes (60) are designed to discourage insects that have reached the interior of the enclosure (20) from exiting the insect trap (10) through the entry pipes (60). Thus, for example, the entry pipes (60) can have an L-shape, as shown in FIG. 3, or otherwise be curved so that the inner openings (80) of the entry pipes (60) generally face downwards toward the bottom of the enclosure (20). In addition, the entry pipes (60) can be constructed from an opaque, preferably dark, material, or may be covered in such a material, so that insects within the enclosure (20) will not perceive sunlight entering the enclosure (20) through the entry pipes (60). It can also be desirable to make the inner openings (80) somewhat smaller than the outer openings (70) so that an insect within the enclosure (20) will find it more difficult to re-enter an entry pipe (60).

[0024] To attract insects to the insect trap (10), insect bait (90) is included within the enclosure (20). Many compositions of insect bait (90) are known and available which will emit a scent which attracts various kinds of flying insects. If the entry pipes (60) are constructed and arranged so that their inner openings (80) face downward, as described above, the attractive scent emitted from the insect bait (90) will rise, enter the entry pipes (90) through the inner openings (80), and exit the entry pipes (60), and the insect trap (10), through the outer openings (70). The scent emitted by the insect bait (90) will thus draw flying insects to the insect trap (10) and the outer openings (70) and lead them to move through the entry pipes (60) to the interior of the enclosure (20) where the insect bait (90) is located.

[0025] Certain compositions of insect bait (90) are generally inactive when dry, but only become active and begin to emit an attractive scent once water is added to the insect bait (90). An insect trap (10) containing such insect bait (90) which is dry will generally have a longer shelf-life when not in use. Thus, in one embodiment the insect trap (10) features a top cap (30) which is removable. The insect trap (10) can be stored with dry insect bait (90). When the user is ready to deploy the insect trap (10), he or she can remove the top cap (30), add water to the insect bait (90), replace the top cap (30), and place the insect trap (10) as desired. In the alternative, the insect trap (10) can be stored without insect bait (90). When the user is ready to deploy the insect trap (10), he or she can remove the top cap (30), add the desired insect bait (90), replace the top cap (30), and place the insect trap (10) as desired.

[0026] It is also desirable, although not necessarily required, that the insect bait (90) include a component with surfactant properties. Insects trapped inside the insect trap (10) may lay eggs directly in the insect bait (90) or which will fall onto the insect bait (90). If the surface tension of the water in which the insect bait (90) rests is reduced by a surfactant, insect eggs laid in or on such water will tend to become submerged, rather than remaining on the surface, and insect larvae will be unable to hatch.

[0027] As illustrated in FIG. 3 and FIG. 8, the enclosure (20) can include threads (100) near its top, while the removable cap (30) can include matching threads (100) to allow the removable cap (30) to be attached and detached from the enclosure (20) using a simple screw-on/screw-off motion. While these drawings show the removable cap (30) fitting over the top portion of the enclosure (20), the insect trap (10) could be constructed so that a portion of the removable cap (30) fits within the enclosure (20) instead. In addition, while a threaded screw-like attachment mechanism is shown here, many other mechanisms, including but not limited to latches, bolts, or spring-loaded release buttons could be used instead to allow the removable cap (30) to be securely but detachably installed on the enclosure (20).

[0028] As described above, the removable cap (30) can include a window (40) made of a transparent or translucent material, such as clear plastic. The inclusion of such a window (40), will allow sunlight to enter the enclosure (20) from above. When trapped, most flying insects will seek an escape route primarily by flying toward the most prominent source of sunlight they can perceive. By allowing sunlight to enter the enclosure (20) from above, the window (40) helps to direct flying insects away from the entry pipes (60) in their attempts to escape. The window (40) can be seen in FIG. 4, in which the insect trap (10) is viewed from above, and in FIG. 5, in which the window (40) is seen from the inside of the enclosure (20) much as it would be viewed by an insect caught within the insect trap (10). While a transparent or translucent window (40) is likely to be the simplest and most effective means of allowing sunlight to enter the enclosure (20) without allowing trapped insects to escape, those of skill in the art will recognize other elements, such as a wire mesh or perforated metal covering, that could be substituted for the window (40) to achieve the same ends.

[0029] In some applications, it may be necessary or desirable to allow a user to add water to dry insect bait (90) or to add insect bait (90) to an empty insect trap (10). Accordingly, in an alternative embodiment of the insect trap (10), the removable cap (30) could be omitted and the enclosure (20) could be constructed with a solid, closed top surface. In this embodiment, the window (40) or other similar element could be included directly in the top surface of the enclosure (20).

[0030] In some applications, it may be necessary or desirable to prevent certain kinds of flying insects from becoming caught in the insect trap (10). Various bee species, for instance, are protected under state and/or federal laws and regulations domestically, as well as the laws of certain foreign countries. In any application where certain kinds of insects are intended to be protected, and the protected insects are somewhat larger than the insects intended to be trapped, an entry cap (110) can be attached to cover the outer opening (70) of the entry pipe (60), as shown in FIG. 6. The entry cap (110) for such an application, detailed in FIG. 7, could be designed with a perforated surface including one or more holes (120) whose dimensions are large enough to allow the targeted insects to enter the entry pipe (60) while being too small to permit the protected insects to enter the entry pipe (60). In the alternative, the entry cap (110) could be omitted, and the entry pipe (60) could be constructed such that its outer opening (70) consists of one or more such holes (120).
