Abstract

An insect trapping device includes a base with a shroud and a cartridge. The cartridge includes an adhesive portion that is positioned adjacent the shroud, when the cartridge is attached to the base. The shroud includes an electric heating element, which heats the shroud and the adhesive portion of the cartridge.

First claim

What is claimed is:

1. An insect trapping device, comprising:
a base comprising a light source and an upstanding shroud having a front surface, the shroud having disposed therein an electric heating element for heating the front surface of the shroud; a cartridge releaseably engaging the base, the cartridge comprising a front housing defining an opening for receiving a flying or crawling insect, a rear housing, and an adhesive portion for trapping the insect, wherein the adhesive portion has a front face and a rear face and is positioned between the front housing and the rear housing, wherein the rear housing and the rear face of the adhesive portion define a bottom opening in the cartridge through which the shroud passes when the cartridge engages the base, wherein the light source is disposed between the front surface of the shroud and the rear face of the adhesive portion and produces light that illuminates at least a portion of the front surface of the shroud and at least a portion of the rear face of the adhesive portion, wherein at least a portion of the light illuminating the portion of the front surface is reflected by the front surface through the rear face of the adhesive portion.

2. The insect trapping device according to claim 1 , wherein the front surface of the shroud is concave.

3. The insect trapping device according to claim 1 , wherein side edges of the shroud are closer to the adhesive portion than a geometric center of the shroud is to the adhesive portion when the cartridge engages the base.

4. The insect trapping device according to claim 3 , wherein a gap between the side edges of the shroud and the adhesive portion is between about 0.5 mm and about 3 mm.

5. The insect trapping device according to claim 1 , wherein the gap between the geometric center of the shroud and the adhesive portion is between about 4 mm and about 12 mm.

6. The insect trapping device according to claim 1 , wherein the light source comprises one or more LEDs that each have a diameter between about 0.5 mm and about 10 mm.

7. The insect trapping device according to claim 1 , wherein the cartridge further comprises a downwardly depending tab that engages a switch in the base when the cartridge engages the base.

8. The insect trapping device according to claim 1 , wherein the adhesive portion has a surface area from about 25 cm 2 to about 150 cm 2 .

9. The insect trapping device according to claim 1 , wherein the base further comprises prongs insertable into an electric socket for providing power to the base.

10. The insect trapping device according to claim 1 , wherein the base comprises the light source.

11. The insect trapping device according to claim 1 , wherein a surface area of the front surface of the shroud is at least 50%, of a surface area of the rear face of the adhesive portion.

12. The insect trapping device according to claim 1 , wherein the rear face of the adhesive portion is substantially planar.
