One nonlimiting variation of a detection arrangement includes one or more
sensors each structured to detect at least one biochemical substance
indicative of biochemistry of one or more target insect species and
provide a corresponding sensor signal, a controller responsive to the
sensor signal of each of the one or more sensors to determine if the one
or more insect species are present and generate a corresponding output
signal, and an indicator responsive to the output signal to indicate the
presence of the one or more insect species.
