Rodents are among the worst pests in North America. They can invade homes, damage property, and spread diseases. From small house mice to burrowing Norway rats, rodents are highly adaptable and can be challenging to control once they establish a presence in your home.\u00a0<\/span><\/p>\n

Understanding the different types of rodents and their habits can help you prevent infestations before they become a severe problem. In this guide, we\u2019ll cover the most common rodents in North America, how to identify them, and the best ways to keep them out of your home.<\/span><\/p>\n

Overview of Rodents<\/span><\/h3>\n

With over 2,000 different species, rodents are one of the largest groups of mammals. What sets rodents apart is their continuously growing incisors, which they use to gnaw on various materials. This unique dental feature allows them to adapt and thrive, making them highly resilient and challenging to control.<\/span><\/p>\n

 <\/p>\n

Characteristics of Rodents<\/span><\/h3>\n

Rodents come in a wide array of shapes and sizes, from the tiny house mouse to the sizable capybara. Their fur also varies significantly in color and texture, depending on the species.<\/span><\/p>\n

How to Identify House Mice<\/span><\/h3>\n

House mice are the most common rodent pest in North America. With their large ears and pointed nose, they\u2019re the classic mouse. They\u2019re usually light brown or gray in color and are small\u2014about 2.5-4 inches long (not counting their tail).\u00a0<\/span><\/p>\n

If you\u2019re dealing with an infestation, their droppings are probably the first thing you\u2019ll see. Dark brown, almost black in color, and shaped like tiny grains of rice, mouse droppings should be handled carefully as this is the main way rodents transmit disease.<\/span><\/p>\n

Why They\u2019re a Problem<\/span><\/h3>\n

House mice reproduce quickly and can squeeze through openings as small as a dime. They contaminate food, gnaw on wiring (a fire hazard), and leave behind droppings that can carry diseases like salmonella.<\/span><\/p>\n
