Abstract: An apparatus and related method for concentrating then killing mosquitos, comprising: a mosquito larvae trap for containing a stagnant, stationary pool of water for luring female mosquitos; a mosquito trapping screen in the shape of an inverted funnel comprising a fine mesh of apertures small enough to prevent mosquitos from passing therethrough, and comprising at least one female entry hole proximate its lower center inverted apex which female entry hole is large enough to allow passage by female mosquitos; the mosquito trapping screen entirely covering a top portion of the mosquito larvae trap to bar entry to the stagnant, stationary pool of water other than by passing through the female entry hole; the mosquito larvae trap further comprising a light-transparent section over at least a substantial portion of its upper perimeter.

Abstract: A germicidal facemask apparatus and related method, comprising: an inner facemask shell comprising at least one inner shell vent thereof; an outer facemask shell shaped to substantially conform to the inner facemask shell; a substantially-airtight attachment of the outer shell with the inner shell about perimeters thereof; a substantially airtight and light-reflective air cavity between the inner and outer facemask shells, formed by the substantially airtight attachment of the outer shell with the inner shell about the perimeters, and by inner shell and outer shell substantially-reflective materials; and an ultraviolet light source configured to introduce ultraviolet light into the air cavity between the inner and outer facemask shells and for the ultraviolet light to substantially permeate the air cavity by virtue of the substantially-reflective materials on the front surface of the inner facemask shell and on the rear surface of the outer facemask shell.
