The key difference in baiting mice when compared to rats is

• A. More bait placements
• B. Higher toxin concentration
• C. Different bait types
• D. Longer exposure period

Answer: (A)

The main idea is how often you need to set out bait to ensure mice encounter it. Mice move in many short, tight routes through walls, clutter, and harborage in a structure. Because of their small home ranges and high local activity, you need to place bait more densely along those frequent travel paths so at least some bait is found and fed on. Rats, by contrast, have larger home ranges and cover more ground, so fewer bait stations spaced farther apart can still reach them. The other factors—toxin concentration, bait type, or exposure period—are determined by product labels and behavior too, but they’re not the primary difference between baiting mice and rats.
