Abstract
The disclosure is directed to a manhole cover, comprising: an upper transparent disc; a lower transparent disc coupled to the upper disc; and means for emitting electromagnetic radiation at a predetermined wavelength that is narrower than full spectrum, the means for emitting electromagnetic radiation operably coupled to the lower disc, wherein: the upper disc has a diameter larger than the lower disc, and the predetermined wavelength is configured to inhibit vermin from inhabiting the volume irradiated by the means for emitting electromagnetic radiation.

A cover, comprising:
- an upper transparent disc;
- a lower transparent disc coupled to the upper disc;
- and
- means for emitting electromagnetic radiation at a predetermined wavelength, the means for emitting electromagnetic radiation operably coupled to the lower disc, wherein:
- the upper disc has a diameter larger than the lower disc, and the predetermined wavelength is configured to inhibit vermin from inhabiting the volume irradiated by the means for emitting electromagnetic radiation.
A method of inhibiting vermin from inhabiting the volume beneath a manhole cover, comprising:
- a. providing a manhole cover, the cover comprising an upper transparent disc;
- a lower transparent disc coupled to the upper disc;
- and means for emitting electromagnetic radiation at a predetermined wavelength that is narrower than full spectrum, wherein the upper disc has a diameter larger than the lower disc, and the predetermined wavelength is configured to inhibit vermin from inhabiting the volume irradiated by the means for emitting electromagnetic radiation;
- and
- b. illuminating the area below the manhole.
A kit for modifying a cover for inhibiting vermin from inhabiting the volume beneath a manhole cover, comprising:
- a light emitting diode array light (LED), configured to emit light at a predetermined peak sensitivity wavelength of the cones present in the retina of the vermin;
- means for powering the LED;
- power level indicator;
- packaging;
- and
- instructions.
