Bot fly

7467.    This was crawling across my living room floor. Is it a bot fly larva? Can they just come into a home on their own? we have no pets or kids. Toronto, Ontario. Canada

Number 7467.  It is a mature bot fly (Diptera: Oestridae; subfamily Cuterebrinae) larva that has emerged from its host (most likely a rodent or rabbit) and is seeking a safe place to undergo pupation. These are incapable of entering buildings on their own. See Bot fly detailed information
