Noises in the Attic

Noises in the attic are worrying and can be an indication that rodents or other wildlife may be living in your roof. Attics can provide the warmth and shelter that rodents, birds and others are looking for. If you hear scratching, scuttling or thumping, that could be a sign of a rodent infestation or another pest problem that should be dealt with as soon as possible.

Attics and lofts provide an ideal habitat for squirrels and rodents. These pests can cause extensive damage to stored items and create serious fire risks by chewing through electrical cabling. It is vital to investigate any unusual noises immediately, as nests and droppings quickly become breeding grounds for insects that can spread pathogens throughout your home.

We understand the specific pest challenges faced by homeowners across Ireland. Our experts are here to help you identify what's making that noise, eliminate the problem safely, and implement effective pest control strategies to reduce the risk of re-infestation.

Inspect your attic and look for visible signs of habitation, commonly their droppings. If you hear or see signs of mice or rats in your attic it may require professional intervention and it is advisable to consult one of our highly trained team for advice.

Identifying Noises in The Attic

  • Light Scuttling & Scurrying: Usually mice. Because they are so small, their movement sounds like light, rapid pitter-patter, often concentrated near the eaves or inside wall cavities.
  • Heavy Thumping & Dragging: Usually rats. Rats are significantly heavier than mice; you will hear "thicker" footsteps and occasionally the sound of them dragging items across the attic floor.
  • Loud Gnawing or Grinding: Signs of rodents (rats/mice) or squirrels. All three have incisor teeth that never stop growing, so they must chew on hard materials like wooden beams, pipework or cables to keep them in good shape.
  • Scratching & Chirping: If the noise is erratic and accompanied by high-pitched squeaks, it could be birds (pigeons/starlings) or, in some cases, bats, which are a protected species.

Identifying Rodent and Other Pest Droppings

  • Mouse Droppings: Thin, oval-shaped (resembling a grain of rice),  about 0.5cm in size, dark in colour, 60-80 droppings a night

  • Brown Rat Droppings: Larger, dark brown, and typically spindle-shaped, 40-50 droppings produced per night

  • Black Rat Droppings: Longer and thinner than brown rat droppings, often curved like a banana with pointed ends

  • Squirrel Droppings: Similar to Brown Rat droppings, rounder, 1½ to 2cms

  • Bat Droppings: Dark brown or black, 4-8mm long. Similar to mouse droppings, but crumble into a fine powder when crushed

How to Get Rid of Mice in The Attic

Mice problems need to be treated quickly, to avoid a greater infestation taking hold. The initial defence is to proof your attic against rodent entry. We have a very effective, professional service for controlling mice. Learn more about mice and professional mouse control in your home. Mice infestations can escalate very quickly, due to their rapid breeding, turning a minor issue into a major problem for your home. These nimble rodents can squeeze through incredibly small gaps, making your attic a prime target for shelter and breeding. We offer highly effective, professional mouse control, protecting your home from future infestations. Beyond the unsettling noises, a mouse infestation poses significant risks:

  • Rapid Breeding: Mice can give birth when they are three months old and can produce litters 6 to 10 times per year.
  • Property Damage: Mice constantly gnaw on hard materials to wear down their teeth, often targeting electrical wires (fire risk), wooden beams, pipes, and insulation, leading to costly repairs.
  • Health Hazards: Mice can spread diseases like salmonella through their droppings and urine, contaminating surfaces and posing health risks to your family. They can also carry fleas, mites and ticks.

How to Get Rid of Rats in The Attic

Discovering rats in your home, even if confined to your attic or other non-living areas, is a serious concern that should be dealt with as soon as possible. Having rats in your attic can cause significant damage and pose considerable health risks, making urgent pest control essential for the safety of your property and family. Like mice, rats can also carry harmful diseases which can have major impacts on your household.

How to Get Rid of Squirrels in The Attic

Squirrels can cause significant damage by gnawing on wood and electrical cables.

Squirrels can be removed by catching them in traps. It is possible to use DIY traps, although great care needs to be taken when handling cages with live squirrels, as they are likely to bite and scratch. It is also an offence to release grey squirrels back into the wild, once caught in a cage; they must be destroyed humanely. In contrast, red squirrels are a protected species and must be released into the wild. Professional treatment of grey squirrels may use mechanical traps. These are effective methods, when applied by appropriately trained, qualified and experienced technicians.

It is essential to protect your home against squirrels to stop them re-inhabiting. This may include cutting back branches overhanging your property, to prevent access to roof spaces.

Call us if you would like further advice about squirrels or if you would like to arrange a visit from a Rentokil technician.

How to Get Rid of Birds in The Attic

Pigeons, gulls, or other birds in the attic create mess, health risks, annoying noise and damage.

Birds should be removed from your home and the entry points need to be blocked, using chicken wire or a solid barrier. It is possible to proof the exterior of your building from pigeons and other birds using spikes, wire systems or netting. To deter birds, it may be possible to scare them away, but a long-term solution is likely to require professional deterrents. Rentokil are experts in all forms of bird control, so if you would like further advice or would like to arrange a visit from a Rentokil technician, please contact us today.

How to Get Rid of Bats in The Attic

Bats are a protected species and it is an offence to try to kill or remove bats or to change or block their roosts.  Even if bats have left your attic, it is an offence to block the roost; bats return to the same place every year, so empty bat roosts are protected.

If you are aware that bats are roosting in your attic, you should consult with the Bat Conservation Ireland before carrying out remedial timber treatments, insect control or rodent control that may cause them harm.

How to Get Rid of Insects in The Attic

Finding insects in your loft is common, often due to pests being drawn to stored items like old textiles, cardboard, or wood. Sometimes, insects appear secondarily, feeding on droppings from other pests like rats or mice.

While deep cleaning and DIY insecticides offer limited control, they rarely solve the full problem because many insects have hidden life stages. For a complete solution, professional insect treatment is often essential. Our Rentokil experts will thoroughly inspect your loft to identify the specific pests and their source. We then use targeted, professional-grade treatments to eliminate the entire insect life cycle and provide advice to proof your loft against future issues.

Don't let loft insects cause damage or disruption. For effective insect control in your home, trust Rentokil.

Rentokil has extensive experience in eliminating insect infestations, so you can be sure we have the right solution for you. Find out more on how to deal with particular insects you may find in your loft:

Noises in The Attic: Frequently Asked Questions


  • Is it normal to hear noises in the attic?

    While many people hear the occasional creak as a house settles, persistent scratching or thumping is not normal and usually indicates that a pest has found a way into your home.


  • How do I know what animal is in my attic?

    You can often identify the intruder by the timing of the noise, as nocturnal pests like rats and mice are active at night, while squirrels and birds are typically heard during the day.


  • What are the weird noises coming from my attic?

    The strange sounds you hear are often the result of specific pest behaviours, such as the loud grinding of teeth against wooden beams or the muffled rustling of animals moving through attic insulation.


  • Why can I hear noises in my loft?

    Your loft provides a warm, dry, and predator-free environment that is highly attractive to wildlife looking for a safe place to nest and breed.


  • How to tell if it's a rat or a squirrel in my loft?

    The most reliable way to distinguish between the two is the "clock test," as rats will be busiest in the middle of the night while squirrels are most active at dawn and dusk.


  • Are attic noises dangerous?

    Attic noises can be dangerous because pests frequently chew through electrical wiring, which poses a significant fire risk, and their droppings can contaminate your home with harmful bacteria.
