A rodent guard configured to be attached to an end of a gutter for preventing rodents from entering the gutter, climbing the gutter to the roof and entering a house is disclosed. The rodent guard may include a gutter receiving opening at one end and a cover receiving opening at a second end generally opposite to the first end. A perforated cover formed from a rigid material may be removably attached to the rodent guard body at the second end that enables the cover to be removed from the base during use such that debris within the gutter can be easily removed from the gutter. The perforated cover may be sized to allow water to pass through the cover, but prevent rodents from entering the gutter through the cover.
