  Thanks to the mid-infrared capability offered by Spitzer, systematic searches
of dust in SNe have been carried out over the past decade. Studies have
revealed the presence of a substantial amount of dust over a broad range of SN
subtypes. How normal SNe present mid-IR excess at later time and turn out to be
dusty SNe can be affected by several factors, such as mass-loss history and
envelope structure of progenitors and their explosion environment. All these
can be combined and related to their environmental properties. A systematic
analysis of SNe that exploded under a dusty environment could be of critical
importance to measure the properties of the dust-veiled exploding stars, and
whether such an intense dust production process is associated with the local
environment. In this work, we firstly use the IFS data to study the
environmental properties of dusty SNe compared to those of normal ones, and
analyze correlations between the environmental properties and their dust
parameters. We find that dusty SNe have a larger proportion located at higher
SFR regions compared to the normal types. The occurrence of dusty SNe is less
dependent on metallicity, with the oxygen abundance spanning from subsolar to
oversolar metallicity. We also find the host extinction of dusty SNe scatters a
lot, with about 40% of dusty SN located at extremely low extinction
environments, and another 30% of them with considerably high host extinction of
E(B-V)>0.6 mag.
