The Multi-Epoch NEArby Cluster Survey (MENeaCS) is a completed search for Type Ia supernovae in 60 low redshift, x-ray luminous galaxy clusters. Executed over two years at a monthly cadence with MegaCam on the Canada-France-Hawaii Telescope, MENeaCS found 22 cluster SNe Ia, all of which were spectroscopically confirmed with follow-up observations. Four of these SNe Ia appear to be hostless, belonging to the intracluster stellar population. In this talk, we will demonstrate the constraints these hostless SNe Ia place on the fraction of light in the intracluster medium (ICM), and discuss the implications of these rates on the origins of the iron abundance in the ICM. We will also show the rate of SNe Ia in cluster galaxies, specifically in cluster ellipticals, and present the characteristics of SNe Ia hosts in our galaxy clusters.
