So, you’ve found evidence of rodents in your home or business, maybe some droppings, or gnaw marks on wood or electrical wires. You may even hear them scurrying around and squeaking at night. But how do you determine which type of rodent is leaving behind this trail of clues? Read on to find out how to spot the sometimes-subtle differences between the tell-tale signs of the most common rodent intruders.
