  Primordial black holes are a possible component of dark matter, and a most
promising way of investigating them is through the product of their Hawking
evaporation. As a result of this process, any species lighter than the Hawking
temperature is emitted, including possible new particles beyond the Standard
Model. These can then be detected in lab-based experiments via their
interaction with the Standard Model particles. In a previous work, we have
first proposed and studied this scenario in the presence of an interaction
between the light new species and nucleons. Here we extend this discussion to
include the case of interaction with electrons. We show that the simultaneous
presence of primordial black holes and species lighter than about $100$ MeV can
be constrained by the measurements of direct detection experiments, such as
XENON1T, and water Cherenkov neutrino detectors, such as Super-Kamiokande. Our
results provide a complementary and alternative way of investigation with
respect to cosmological and collider searches.
