The de Broglie wavelength is
independent of the charge and nature of the material  particle It is
significantly measurable (of the order of the atomic-planes spacing
in crystals) only in case of sub-atomic particles like electrons,
protons, etc (due to smallness of their masses and hence, momenta) However, it is indeed very small, quite beyond measurement, in case
of macroscopic objects, commonly  encountered in everyday life
