Which type of waste would NOT attract house flies?

Plastic waste would not attract house flies primarily because it is non-biodegradable and does not emit the organic odors that attract these insects. House flies are primarily drawn to decaying organic materials, such as animal manure, decomposing food, and garbage, which provide them with nutrients and suitable breeding sites. These materials contain compounds that produce strong odors and signals that are appealing to house flies looking for food sources or places to lay eggs. Since plastic does not decompose and does not provide the necessary nutrients or odors, it lacks the qualities that would entice house flies.
