Of all rodents, rats are universally disliked. Unlike mice or chipmunks, rats have the worst reputation for good reasons. They are destructive and carry parasites and diseases that can be passed on to people and pets. When you hear a rat on the roof, it’s time to spring into action quickly, as these multiply fast.

Roof rats in the attic fit into tight spaces, entering attics through vulnerable gaps in the roof and soffits. They love attics because they are dark, warm, and mostly undisturbed places. Within a home, they have a reliable source of food and water, are out of bad weather, and can safely create a nest in which to raise their babies.

Despite remaining out of sight and avoiding contact with humans, rats still leave signs indicating their presence within the home.

Signs of Roof Rats in Your Attic

Some signs that you have roof rats in the attic are more readily apparent than others. Here’s what to look out for:

  • Scurrying or scratching sounds coming from your attic at night.
  • Roof rat droppings not only in your attic but on kitchen counters, in your pantry, or along baseboards where rats travel from the attic to access food and water.
  • Gnaw marks on wood beams, wires, and other structural objects.
  • Greasy smudges along baseboards or walls where roof rats navigate from one area to another.
  • A musty odor made by rat urine. Rats urinate often and everywhere.
  • Finding torn insulation, cardboard, and other materials used to build their nest.
  • Seeing an actual rat either in your attic or as it is traveling.

Roof Rat Droppings

Like many rodents, roof rat droppings look like small, dark capsules with tapered edges scattered wherever these rodents have traveled. They will most likely be found near nesting sites, food sources, and along their pathways. If you have roof rats in the attic, check for an accumulation of roof rat poop in dark corners, on insulation, and on the tops of beams and boxes of stored items.

Roof Rat Nests

Roof rats build nests that serve as a place for them to sleep, give birth, leave babies while they are out scavenging food, and as a place to store the scavenged food.

Nests look much like woven balls and look similar to bird nests. They use whatever soft materials they can find. In an attic, they are often made from shreds of insulation, torn-up paper, cardboard, and cloth.

Roof rats look for warm, secluded spots to build and maintain their nests. You’ll often find them in a corner of the attic or up on a rafter.

Roof Rat Sounds

As roof rats are nocturnal, you’re probably most likely to hear sounds at night that include:

  • Roof rats make high-pitched chirps and squeaks to communicate with other rats or when they feel threatened.
  • Scurrying and scratching noises as their feet move along surfaces such as floors and rafters or when they are building their nest. Even though these sounds are soft, they can be heard at night when all is still.
  • Roof rats gnaw at wood and wires to maintain their teeth. Because rat teeth continue to grow throughout their lives, they need to gnaw to keep them at a manageable length.
  • If they are tearing insulation and pieces of cardboard when building their nest and when they are in your drawers or pantry, you may hear the sound of objects moving as they rustle through things.

Why Roof Rats Are Harmful

Roof rats can pose serious threats to both your property and health. The level of property damage depends on the size and extent of the infestation, and homeowners who suspect an infestation should take action quickly to limit the threats roof rats pose.

Health Issues

Roof rats carry both parasites and diseases that can be transmitted to you and your family through their feces, urine, nesting materials, and the contamination of food. Parasites include ticks, fleas, and mites. The Centers for Disease Control lists about a dozen diseases that can be contracted from roof rats, including Hantavirus, Leptospirosis, Typhus, and Monkeypox.

Property Damage

Roof rats can cause serious and costly damage to rafters, insulation, wiring, and more. And the damage increases exponentially as they reproduce and grow in numbers. The damage they cause to wiring can also be a fire hazard.

Damage caused by roof rats can also decrease the value of your home, leaving a homeowner with costly repairs to attract buyers. It’s especially important to clear up any sanitation issues caused by a previous infestation.

How Roof Rats Got Into the Attic

Roof rats got their name from their ability to climb and live in elevated areas such as trees and vine-covered fences. Their long tail provides them with supreme balance skills, and they can easily walk across utility lines and tree limbs to hop onto rooftops. Once there, they take advantage of any gaps or worn areas where they can chew their way inside.

What to Do if Rats Are in the Attic

Because roof rats are so destructive and reproduce quickly, it is best to call a professional rat removal service. It is the one sure way to know that the entire infestation has been removed.

Critter Control’s rat removal service is ideal because, in addition to your free inspection, their services include removal, exclusion, and damage repair. Recognized as an industry leader, their technicians are expertly trained in getting and keeping rats out. Call (800) 274-8837 to schedule your free inspection.

How Critter Control Performs Attic Remediation

Our experienced team at Critter Control provides professional attic remediation services after rodent infestations to restore your attic to its clean, rodent-free state. This process includes:

Inspection

First, we thoroughly check your attic to determine:

  • Rodent activity.
  • The extent of damage from animals to insulation, wiring, or wood.
  • Potential entry points rodents may use to enter the attic.

This gives our team a better idea of what we’re dealing with, ensuring we can effectively address all problems before beginning remediation.

Clean Up

Rodent infestations leave behind contaminated materials that must be carefully removed. Our cleanup process includes:

  • Safely disposing of nesting materials and rodent droppings.
  • Using specialized sanitizers, such as industrial-grade disinfectants, to disinfect the area.
  • Eliminating harmful bacteria and odors to make your attic a safe environment once more.

Remove and Replace Insulation

Your uninvited attic guests may damage insulation during their stay, nesting in it and contaminating it with urine and droppings. During our inspection, we’ll evaluate the insulation and replace it if necessary. Generally, we recommend replacement when:

  • Areas are heavily contaminated with rodent waste.
  • Insulation has suffered significant water damage.
  • Insulation is old and no longer effective.
  • There are signs of mold or mildew growth.

We can help prepare insurance bids for insulation replacement to ensure a seamless transition. We work with most major insurance companies to ease the financial burden.

TAP Pest Control Insulation

As part of the remediation process, we offer Thermal Acoustical Pest (TAP) Control Insulation. This is a specialized insulation that offers multiple advantages over run-of-the-mill insulation, including:

  • Pest resistance: TAP insulation is infused with boric acid, which deters insects and other pests.
  • Energy efficiency: It helps with temperature regulation, adding a layer of insulating protection that reduces heating and cooling costs.
  • Noise reduction: TAP insulation offers superior soundproofing compared to traditional insulation, helping keep your home quieter and more comfortable.

We install TAP insulation to provide long-term protection against future infestations while improving energy efficiency and reducing noise.

Seal Entry Points

Preventing future rodent infestations requires sealing all entry points. Since rodents can squeeze through incredibly small spaces, we use various materials depending on the size of the opening:

  • For small gaps: Steel wool, mesh, or caulk
  • For larger holes: Cement, metal, or hardware cloth

These materials serve as rodent deterrents, effectively preventing the critters from squeezing through. We choose the most appropriate material based on the location and size of the gap to ensure long-term protection against uninvited creatures.

How to Keep Roof Rats Out of the Attic

Keeping roof rats out of your attic requires diligence and putting preventive measures into place. Here are some things you can do to minimize your exposure and lessen the chances of an infestation:

  • Monitor your home and yard for signs of rodent activity, such as droppings, gnaw marks, and strange noises coming from the attic.
  • Keep the trees, vines, and shrubs around your home trimmed so as not to provide easy access for rats on the roof. Some people install tree guards to prevent them from climbing onto your roof from the trees nearest to your house.
  • Store firewood and lumber at least 100 feet away from your home.
  • Keep your yard free from natural debris and stored items to eliminate hiding spots and nesting areas.
  • Keep your roof, eaves, and soffits in good condition. Add mesh or covers to vents. Seal cracks and gaps with caulk or metal flashing. Make sure there are seals where utilities enter your home.

When you have your free inspection, ask your Critter Control technician about exclusion services that can help you guard against roof rats entering your home. Critter Control will develop a plan specific to your property for deterring an infestation.

Since roof rats are smaller than other rat species and are active while you are asleep, their presence can unfortunately go unnoticed. That’s why exclusion is an essential and proactive pest management strategy for preventing another infestation from occurring.

We had such a great experience with Critter Control at every interaction. Many months ago, my friend and I called to get some advice on how to handle a bat in our home. The lady we spoke with took the time to give us free, down to earth, real advice. I remembered the experience so when it came time to batproof our attic, they are who we called. The gentleman that came out to do the quote was thorough and patient in explaining everything. The gentlemen that did the bat proofing were quick, efficient and friendly. A few months later we had them back to clean out and insulate our attic. Very friendly crew, extra helpful, and were respectful to our home and good with our German Shepherd. Just a stellar experience all around. Recommended them to my friend, and I'll recommend them to you!

I couldn’t be happier with my experience with Critter Control and, especially, with Taylor and his partner. Taylor called the evening before my appointment to confirm and took the time to explain what they would be looking for and what the inspection would involve. He also let me know that I would receive a written estimate when they were finished, which I really appreciated. The next morning, Taylor called before arriving and showed up right within the scheduled window. He introduced himself and his partner, and they were both extremely professional and courteous. They took their time inspecting the yard and ultimately determined that I was dealing with both moles and gophers. Taylor walked me through the treatment options, answered every question I had, and made sure I understood what they were recommending. There was absolutely no pressure, and I really appreciated how straightforward and transparent the entire process was. I had a written estimate in hand within about 10 minutes of them completing the inspection. From the initial phone call to the completion of the inspection, everything was handled professionally and exactly as promised. It’s refreshing to deal with people who communicate well, show up when they say they will, and genuinely take the time to answer your questions. Thank you, Taylor, for making the process so easy. I’m very happy with the experience and would definitely recommend Taylor and Critter Control!

I had a appointment with Moises today to investigate noises that I had been hearing in my wall. I explained what I had been hearing and for how long, and he said that he was going to look for any potential entry points. He found two areas that were compromised and showed me pictures of the areas, and told me what he thought was the culprit and also explained the plan to make sure that there weren't any other rodents in the wall by putting in a one way door and then after 5 days, they would sanitize the area in the wall and seal up the two areas, so that nothing else could get inside. He was very professional and friendly and explained everything to me that they were going to do to alleviate the situation. I would definitely recommend Moises and Critter Control for any wildlife removal services in the future.
