What they do and what attracts blow flies:

Blow flies are most commonly found around dead animals such as birds. But they also like all decaying organic matter dead or alive. For example they are known to lay eggs inside the open wounds of cattle and other animals. They will also lay eggs in your garbage can if you have rotten food like meats in there. Blowflies are also commonly found around animal faeces.

Blow flies are heavily attracted to dead carrion and other dead things. This is because the larvae of Blow flies burrow into and feed on the dead remains. Blow fly larvae need a lot of protein to develop and this is why dead meat is the preferred breeding ground. After 3 weeks to a month the Blow flies larvae will be fully grown.
