b.Houseflies
c.Rats
d.Mice that ate extra food
Explanation
Rat droppings are noticeably larger than mouse droppings — roughly 3/4 inch (about 1.9 cm) long, while mouse droppings are about 1/4 inch (rice-grain size). Cockroach droppings look like ground pepper or coffee grounds. Identifying dropping size helps target the right control plan.
