Why identification matters
The species determines trap size and placement, how entry points are sealed and whether the problem is high (attic) or low (ground level). See rodent signs and how to prevent rodents.
Getting help
We can identify the rodent from droppings, rub marks and location. Learn about rodent control and how to reach our Fort Lauderdale pest control team.
