Pack rats, also known as wood rats, are a prevalent nuisance in Colorado. Often inhabiting wild areas, they tend to invade homes for food and shelter. They are notorious for collecting items from houses to build nests in hidden spots like walls and attics (hence the name). Contact a professional pest control agency ASAP if you suspect a rodent infestation, as the damage they cause can be extensive and expensive to fix.

Pack Rats: The Hoarders of the Rodent World

Pack Rats or wood rats are similar to standard house mice, except they are slightly bigger with a bushier tail. They are known for their peculiar habit of collecting various objects to build their nests, which, over time, may become problematic as the gathered materials can block vents, damage insulation, and create fire hazards. You will notice that small household items disappear as they are attracted to shiny objects. Pack rats often inhabit rocky areas, but like mice, they can invade homes, garages, and outbuildings in search of warm shelter. These nocturnal creatures are particularly active during the fall and winter, seeking refuge from the colder temperatures.

Recognizing Pack Rat Infestations

Nest Locations: Pack rats typically build their nests in secure, warm places like attics and walls, often under eaves, porches, or decks. They can enter homes through existing holes made by other animals. Finding nests in these areas is a strong indicator of an infestation.

Noises in Walls: Hearing rustling sounds inside your walls can signify pack rats. These noises often indicate their presence as they seek safety from predators indoors. Since they can chew through materials like wiring and insulation, it’s important to address this early to prevent severe damage.

Rat Droppings: Discovering mouse feces is another sign of an invasion. These droppings are unsanitary and can pose health risks due to the diseases these pests can carry.

Management and Preventive Measures

Effective management of mice and pack rats involves a combination of prevention, exclusion, and removal. Homeowners should focus on sealing cracks and openings in the home’s exterior, reducing clutter, and keeping food in sealed containers. Regular inspection of attics, basements, and storage areas is also vital to detect any early signs of rodent activity.

For pack rats, reducing outdoor debris and clutter can make your property less attractive to them. Since they are attracted to shiny objects, be mindful of leaving small, reflective items outside. Be sure to seal off potential entry points, such as gaps around pipes, windows, doors, and siding boards. Regular inspection and maintenance can help identify and block these access points early. Homeowners should be vigilant about maintaining cleanliness and reducing clutter to deter these unwelcome guests.
