![]() ![]() The apparatus of claim 8, wherein at least a portion of the sidewalls includes an outer surface sloping downward from the upper edge at an angle in the range of 20 to 70 degrees and wherein the outer surfaces are textured to provide high traction surfaces for crawling insects.ġ3. The apparatus of claim 8, wherein the inner surfaces each comprises a layer of ultra high molecular weight polyethylene.ġ2. for at least about 7 minutes, whereby the base plate acts as an extermination element for exterminating insects proximate to the upper surface.ġ1. The apparatus of claim 9, wherein the heat element second operates to heat the upper surface of the base plate to a temperature of at least about 113° F. The apparatus of claim 8, further comprising a heat element abutting a lower surface of the base plate and operating to heat an upper surface of the base plate to a temperature for at least about 85° F., whereby the base plate acts as a thermal lure for parasitic insects.ġ0. A pitfall trap apparatus, comprising: a base plate sidewalls extending about the periphery of the base plate to define a well with a predefined depth, wherein the sidewalls each have an inner surface extending from an upper edge toward the base plate, wherein the inner surfaces are low traction surfaces, and wherein the inner surfaces each slopes downward from the upper edge at a pit side angle, as measured from horizontal, in the range of 30 to 75 degrees.ĩ. The insect trap of claim 4, wherein the second period of time is at least about 7 minutes and is less than the first period of time and wherein the controller repeats the first and second heating operations of the heat source during an operating time period.Ĩ. The insect trap of claim 4, wherein the extermination temperature range includes temperatures greater than about 113° F.ħ. The insect trap of claim 4, wherein the lure temperature range falls within the range of 85 to 100° F.Ħ. ![]() The insect trap of claim 1, wherein the controller operates to first heat portions of the heat source exposed to the pit to a first temperature within a lure temperature range for a first period of time and to second heat the exposed portions of the heat source to a second temperature within an extermination temperature range, and greater than the first temperature, for a second period of time.ĥ. The insect trap of claim 1, wherein the heat source further comprises a resistive heat element contacting a surface of the base plate and operable by the controller to heat the base plate.Ĥ. The insect trap of claim 1, wherein the inner surfaces are sloped at an angle, measured from vertical, of more than about 20 degrees.ģ. ![]() An insect trap for use in trapping and exterminating crawling insects, comprising: a pit fall trap assembly including sidewalls defining a pit within the sidewalls, wherein the pit fall trap assembly further includes a heat source positioned within the pit and a controller assembly with a controller selectively operating the heat source, wherein the heat source comprises a base plate provided at a bottom of the sit adjacent to lower edges of inner surfaces of the sidewalls, and wherein the inner surfaces comprise a layer of anti-traction material.Ģ. ![]()
