Rat in Attic

Finding out that there is rat in attic may feel like a minor irritation, however the damage these small rodents can do should not be taken lightly. Attics are an ideal location for rats, as they are safe, dark and quiet. If you’ve discovered you have visitors living in your attic, it’s important that you act quickly to remove them, before they cause any (further) damage.

Whenever rats live in attics they create dangerous environments for both the inhabitants of a house and the house itself. While we might think that rats are ground-dwellers, many are actually skilled climbers and can easily find their way into roofs or attics. Rat in attic, and the bugs they bring with them, are potentially very dangerous to a person or pet’s health, and can also cause structural or material damage to your home.

Light scurrying noise at night, anywhere in the attic or walls. Not much else to say. They sometimes sound very fast. If the acoustics are right, they can sound much bigger than they are.


Rats can climb pretty much any surface. They can get wherever they want to go. They can squeeze through amazingly small holes and gaps. They can get in through the sewer pipes or any possible gap or hole in a home, from the foundation to the tip of the roof. They can also chew. If a rat detects just a small breeze coming from inside, they'll get in.


Rats leave a ton of droppings, sometimes tens of thousands of droppings in an attic - they look like 1/3 inch brown thick grains of rice, very similar to squirrel droppings. They also leave tunnels and trailways in the insulation. They also leave chew marks, and interestingly, they leave brown smudges from grease in their fur, and this lines the commonly travelled rat routes. You might see chew marks, on pipe insulation, wood, or electrical wires.

how to help keep out rat in attic?

Here are some things you can do at home to help prevent rats from entering your attic:

  1. Seal any holes or cracks in your home that are larger than one-fourth of an inch. A hole or crack that small is all a mouse needs to enter your home and a full-grown rat only need a one-half of an inch hole.
  2. Make sure ivy and tree limbs are trimmed back from the sides of your house. Rats are good climbers and these things can provide access to the roof. Some species of rats even nest in trees or other locations off the ground.
  3. Stack firewood and piles of debris far from your house, as these are potential shelters that could attract rats and may provide a hidden location for their burrow entrance.
  4. Store food — including pet food — in airtight containers so that rats aren't able to smell it.
  5. Keep outdoor trash cans sealed and make sure compost piles are far from the home so that these attractants don’t give rats the impression that your attic is a safe haven with a nearby all-you-can-eat buffet.
  6. Contact a rodent control professional to inspect your home for potential rodent entry points and recommend an exclusion plan for sealing rodents out.

Health Risks

Rats are one of the best disease-carriers in the animal kingdom, and were directly responsibly for the deaths of millions of people during the time of the bubonic plague. It is important to prevent existence rat in attic. Although the plague died out, rats still have the potential to make people and pets very sick in the following ways.

  • Contamination

    Rats are omnivorous, but are most likely to scavenge a vegetarian diet than actually kill something. Consequently, the will find a way to get into any and every food source near their nest, which is likely to be your kitchen or pantry if they have taken home in your attic. Eating food or drinking water that has been contaminated with rat saliva, urine or scat is potentially very dangerous for humans. Diseases that are transmitted via contamination are Hantavirus Pulmonary Syndrome, Leptospirosis and Salmonellosis, amongst others.

  • Bites and Scratches

    Wild rats are not friendly creatures – if cornered and without an opportunity to flee they will scratch and bite anyone who tries to approach them. If this does happen, the person bitten or scratched would have to immediately see a doctor to ensure they do not contract tetanus or rat-bite fever, both of which can be contracted after the rat is dead.

  • Fleas and Mites

    Rats bring with them other critters that can cause disease, such as ticks and fleas. These can infect any household occupant, from pets to people.
