What’s That Noise in My Roof (or Walls) at Night?

Hearing scratching, scurrying, thumping, or tapping in your roof or walls at night can be unsettling.

If the noises are happening consistently after dark, there’s a strong chance a pest has made its way into your roof cavity or wall space.

At Hitman Professional Pest Control, roof and wall noise investigations are one of the most common call-outs, and the cause is usually something that won’t go away on its own.

Why You Hear It More at Night

Most nuisance pests are nocturnal, meaning they become active once the sun goes down. When your home is quiet, even small movements can sound much louder through ceilings and wall cavities.

If the noise happens:

• Around the same time each night
• Stops during the day
• Sounds like movement rather than expansion

It’s likely a living animal, not just normal house settling.

Common Causes of Roof & Wall Noises

Rats

Sounds like:

• Rapid scratching or scurrying
• Light running across the ceiling
• Occasional squeaking

Rats are agile climbers and can enter through very small gaps in rooflines, vents, or eaves. Once inside, they nest in insulation and can chew through electrical wiring — creating serious fire risks.

---

Mice

Sounds like:

• Light scratching inside walls
• Subtle gnawing
• Quick, light movement

Mice are smaller and often nest inside wall cavities rather than open roof spaces.

---

Possums

Sounds like:

• Heavy thumping
• Loud dragging
• Sudden banging

Possums are much heavier than rodents, so their movement is often obvious. Because they are protected wildlife in many areas, removal must be handled properly and legally.

---

Birds

Sounds like:

• Flapping
• Nest-building scratching
• Early morning chirping

Birds can enter through broken tiles or small roof gaps and build nests inside cavities.

When Should You Be Concerned?

Arrange an inspection if you notice:

• Repeated nightly scratching
• Chewing sounds
• Droppings in roof space
• Strong or unusual odours
• Visible ceiling damage

Rodent infestations escalate quickly, and the longer they remain, the more damage they cause.

Don’t Let It Keep You Up at Night

If the noises have lasted more than a few nights, they are unlikely to resolve on their own.

Rodents, in particular, multiply rapidly. A small problem can turn into a full infestation in a matter of weeks. Mice can breed every 3–4 weeks, and a single pair can produce dozens of offspring in a short period of time.

Beyond the noise and property damage, there are also serious health risks to consider. Rodents contaminate insulation, ceilings, and food storage areas with droppings and urine. They can spread bacteria, trigger allergies and asthma, and introduce parasites such as fleas and mites into your home.

The longer the issue is left untreated, the greater the risk to your property and your family’s health.

Early action is always simpler, safer, and more cost-effective.

Why Professional Treatment Matters

DIY solutions can sometimes create bigger problems than they solve.

Using poison may result in rodents dying inside walls or roof cavities, leading to strong odours and difficult removal. Sealing entry points too early can trap pests inside your home, and without a proper inspection, infestations can continue unnoticed in roof voids and wall cavities.

That’s why Hitman Professional Pest Control conducts thorough inspections before any treatment begins: identifying entry points, assessing the level of activity, and ensuring the problem is handled properly from the start.
