Meat, fish, cooked leftovers, spoiled food, pet waste, and other moist organic materials can be especially attractive.

The speed is one reason people find infestations so confusing.
You may look inside the bin one day and notice nothing unusual. Shortly afterward, numerous larvae may be visible.
The

Why Trash Bins Are So Attractive to Flies
A garbage container can accidentally provide several things flies need in one place: food, moisture, warmth, organic material, and a relatively protected environment.
