  We examine the impact of a faster expanding Universe on the phenomenology of
scalar dark matter (DM) associated with $SU(2)_L$ multiplets. Earlier works
with radiation dominated Universe have reported the presence of desert region
for both inert $SU(2)_L$ doublet and triplet DM candidates where the DM is
under abundant. We find that the existence of a faster expanding component
before BBN can revive a substantial part of the desert parameter space
consistent with relic density requirements and other direct and indirect search
bounds. We also review the possible collider search prospects of the newly
obtained parameter space and predict that such region might be probed at the
future colliders with improved sensitivity via a disappearing/stable charged
track.
