  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 major 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 show that such region can be probed at the future colliders
with improved sensitivity via a stable charged track.
