Roof rats, also known as Rattus rattus, are a common pest in homes and businesses, particularly in warmer climates. These agile rodents are notorious for their ability to climb, making them frequent invaders of upper levels, attics, and roofs. Because of their destructive habits and the health risks they pose, it's essential to address a roof rat infestation as soon as it’s detected. In this blog, we’ll answer frequently asked questions about these pests and provide effective solutions to get rid of them.
What Are Roof Rats?
Roof rats, sometimes called "black rats" or "ship rats," are smaller than their cousins, the Norway rats. They have slender bodies, long tails, and darker fur, making them adept climbers. They often nest in high places like attics, ceilings, and rooftops, where they find safety and shelter. Due to their preference for elevated areas, they are particularly problematic in homes with accessible rooflines or tall trees nearby.
Roof rats are especially concerning because they can cause significant structural damage. Their sharp teeth can gnaw through electrical wires, aluminum siding, and even wood. Beyond the physical damage, they can also contaminate food sources, leaving behind droppings that spread bacteria and viruses.
Why Are Roof Rats Bad?
Roof rats pose several serious risks, both to the structure of your home and the health of your family. These rodents are known carriers of diseases such as rat bite fever, salmonella, and the bubonic plague. While modern medical advancements have mitigated the widespread threat of plague, it remains a rare but dangerous risk. They can also trigger allergic reactions in sensitive individuals due to their droppings, urine, and dander.
In addition to health risks, roof rats can compromise the safety of your home. Their habit of chewing on electrical wires can create a significant fire hazard, and their gnawing on pipes and insulation can cause water damage or reduced energy efficiency. These pests are also a threat to pets, as they are attracted to easily accessible pet food left out in garages, backyards, or even inside your home.
Because they reproduce quickly, infestations can escalate in a short amount of time. A single female can have multiple litters per year, resulting in a rapid increase in the rat population if left untreated. That's why early intervention and prevention are so important.
How Can I Tell If I Have Roof Rats?
Spotting the signs of a roof rat infestation early is crucial for minimizing damage. Here are some common signs of a roof rat infestation:
- Droppings: Roof rat droppings are smaller and more pointed compared to the droppings of other rat species like Norway rats.
- Gnaw marks: These can appear on wood, electrical wires, aluminum siding, and even food packaging. The gnaw marks are typically smaller due to the smaller size of roof rats.
- Scratching noises: You may hear scratching or scurrying sounds in your walls, ceilings, or attic, especially at night when these nocturnal creatures are most active.
- Nesting materials: They use materials like shredded insulation, cardboard, and other soft materials to build nests in hidden areas of your home, usually in the upper levels like attics or ceilings.
- Daytime activity: Seeing a roof rat during the day can be a sign of a larger infestation, as rats typically only come out during daylight hours when their population has grown too large for the available food supply.
What Attracts Roof Rats to My Home?
Roof rats are drawn to your home for the same reasons as other pests: food, water, and shelter. Some specific attractants include:
- Unsecured pet food or birdseed left out overnight.
- Fallen fruits or vegetables in gardens or near your home.
- Cluttered attics or garages that provide hiding and nesting places.
- Access to water sources such as pet water dishes, leaking pipes, or bird baths.
- Overgrown shrubs, trees, or vines that provide easy access to your roofline.
By eliminating these attractants, you can reduce the likelihood of a roof rat infestation.
How Do I Get Rid of Roof Rats?
If you suspect a roof rat infestation, it’s critical to take action quickly to prevent further damage and health risks. At Alta Pest Control, we specialize in effective rat control solutions. Our approach includes a combination of trapping, exclusion, and ongoing maintenance to ensure that roof rats are eliminated and prevented from returning.
Bait Boxes and Sticky Traps
To get rid of roof rats, we set up bait boxes and sticky traps in strategic locations around your home. These traps are highly effective at reducing the rat population and controlling the spread of the infestation. We use highly irresistible bait in our bait box traps to lure roof rats, ensuring the traps are as effective as possible.
Rodent Exclusion Work
In addition to trapping, we offer rodent exclusion work to seal any entry points that roof rats may use to access your home. This involves sealing cracks, holes, and gaps in your home’s exterior, including around windows, doors, and siding. Exclusion is a vital step in ensuring that rats do not re-enter your home after they’ve been removed.
Preventive Measures
Once the roof rats have been eliminated, we go beyond just removing them—we offer preventive maintenance to ensure they don't come back. Our team will reset bait boxes every quarter and replace sticky traps as needed. If you notice any new signs of a roof rat problem, we’ll come out and re-service the area promptly at no additional cost.
What Other Measures Can I Take To Prevent Roof Rats?
Preventing a roof rat infestation involves making your home less attractive to these pests. Here are some steps you can take to reduce the likelihood of an infestation:
- Store food securely: Keep all food, including pet food, in sealed containers, especially in kitchens, pantries, and garages.
- Keep outdoor areas clean: Regularly clean up fallen fruits, vegetables, and debris from your garden or yard.
- Trim back trees and shrubs: Roof rats are excellent climbers, and overgrown trees or shrubs can give them easy access to your roof. Trim these back to at least three feet away from your home.
- Seal entry points: Check your home’s exterior for cracks, gaps, or holes, especially around windows, doors, and eaves, and seal them with caulk or other materials.
- Remove water sources: Fix any leaking pipes or faucets and eliminate standing water sources like bird baths or pet dishes.
