The halos of BCGs play a crucial role in the understanding of the star formation history of BCGs and provide unique information about the starburst host. We intend to investigate the outer regions of a sample of luminous Blue Compact Galaxies (BCGs) that show a red color excess in our previous deep optical and near-IR data. These colours have been compared to spectral evolutionary models and found to be inconsistent with an expected old metal poor stellar population. Possible models for the excess include reddening by a dusty circumgalactic shell. We propose to use Spitzer to test this option in a search for cold dust at 70 and 160 micron in 5 BCGs. For comparison we will also observe 7 starburst host galaxy and postburst candidates for which we recently obtained deep optical/near-IR photometry. In addition, we propose to use IRAC to search for excess emission from hot circumstellar dust from late type stars in halos of two of the BCGs.
