Homeowner searches attic for pests

Even the smallest bump or gentle scratching can grab your attention, and many residents in Long Island are surprised by how often it happens. You may find yourself wondering if itโ€™s ordinary settling or something moving where you canโ€™t see it. These moments of uncertainty occur more frequently than you might expect.

Wildlife and pests tend to make small sounds that betray their presence. Raccoons, squirrels, birds, and mice often provide clues through their movements. The noises can shift throughout the day depending on their activity and location.

This guide from Arrow Exterminating helps you interpret these signs. By observing when the noise happens and where it seems to come from, you can identify the culprit more easily. Once you understand the pattern, deciding how to address the problem becomes much clearer.

What Do Those Unusual Sounds Really Mean?

When you hear something unusual, start by focusing on the basics. Listen to how the sound behaves, where it seems to come from, and how often it repeats. These simple observations can be surprisingly helpful and make identification far less confusing.

Small hints often bring quick answers. A tiny thump or faint scrape can point toward the source before you realize it. Tracking whether the noise travels or grows in strength adds valuable context that brings everything into focus.

Frequent Noises That Come From Within Your Walls

The walls of a home can become hiding places for all sorts of creatures, from small insects and mice to larger critters such as raccoons. When bigger animals push their way through narrow gaps, they tend to bump into things or brush against surfaces, causing sounds you can easily notice. These are the types of noises most frequently heard coming from within your walls:

  • Heavy Dragging Sounds in the Walls
    A steady dragging or slow shuffling sound overhead or beneath the floor often points to a larger animal inside your home. These noises differ from the quick, light movements of squirrels and tend to be more intentional. Possible animals include:

    • Opossums: Opossums often move with slow, steady thumps, paired with occasional scratching as they travel through attic or wall spaces.
    • Raccoons: Raccoons tend to create heavier thuds and pronounced scratching noises as they climb, explore, or search for food within ceilings and walls.
  • Thumps on the Roof
    Any overhead thudding, light or loud, is often a sign of wildlife traveling over your roof. Creatures frequently use this space as a route while exploring for meals or protection. Animals that may be responsible include:

    • Squirrels: Quick, light scampering and the soft thump of nuts dropping or rolling are usually daytime sounds. Their movements are fast and much lighter than those of bigger animals.
    • Cats: Light, quick footsteps often occur at night or during early morning and evening hours. You might also hear occasional meowing or purring near possible entry spots.
    • Raccoons: Heavy, purposeful steps or strong thumps are most common at night. Their size makes each movement across the roof easier to hear.
    • Tree Branches: Branches that scrape or hit the roof can create noises that seem like animal activity, especially on windy days. This is one of the most common non-pest sources of rooftop sounds.
  • Bumps in Your Attic or Crashes in the Garage
    Many larger creatures move into garages and attics when theyโ€™re seeking a safe place to hide or forage. With wide, open layouts and minimal insulation, these spaces make their movements noticeably louder. Examples include:

    • Birds: Birds that become trapped often flap and hit surrounding objects, creating chaotic sounds as they try to escape.
    • Mice and Rats: Agile and quick, these rodents scurry, climb, and sometimes knock over small items, producing loud clattering noises.
    • Raccoons: Active at night, raccoons frequently topple tools, bins, or boxes, and their larger size makes every disturbance more noticeable.
    • Opossums: Their awkward movements often lead them to bump into or knock over stored items while foraging in the dark.
  • Rustling in Vents or Chimneys
    Random flutters, flaps, or rustling often point to birds or bats caught inside. These sounds are frequently heard coming from vents or chimneys. Potential culprits include:

    • Birds: Birds that become trapped often make frantic flapping and crashing noises as they hit walls, vents, or chimneys while attempting to escape.
    • Bats: Bats may produce fast fluttering sounds or high-pitched squeaks as they try to exit confined spaces such as attics or vents.
  • A Buzzing or Humming in the Walls
    A steady buzz or hum often points to the presence of stinging insects. This noise is caused by countless wings moving quickly and is most noticeable on sunny, warm days. Insects responsible for these sounds include:

    • Wasps: A constant, piercing humming sound often signals wasps building a nest inside your walls.
    • Hornets: Loud, forceful buzzing usually indicates hornets are active within a wall cavity.
    • Bees: A steady, low-pitched hum generally points to a bee colony nesting in a wall or attic space.
  • Ticking or Clicking Inside Walls
    Gentle, ongoing clicking or ticking noises within your walls may indicate wood-destroying insects. They often happen in bursts, making nighttime the ideal time to hear them. Possible culprits include:

    • Termites: Steady, subtle clicking or tapping noises inside walls may indicate termites feeding on the wood.
    • Carpenter Ants: Soft, irregular ticking or rustling from wooden beams or structures often signals carpenter ants at work.
  • Gnawing or Grinding in Walls
    Rodents constantly gnaw on things like wood, plastic, and wiring to manage the length of their teeth. These sounds often repeat and are usually heard at night or before dawn. Common offenders include:

    • Mice and Rats: These rodents are usually most active at night, with mice quietly searching for food and rats chewing or moving through hidden areas after dark.
    • Squirrels: Active primarily during the day, squirrels make noticeable noises as they dart through wall cavities or other narrow spaces.
  • Scratches in Walls
    The sound of scratching can be unnerving, but tracking its rhythm and location can point to the source. Does it remain in one area or move? These are the most frequent offenders:

    • Raccoons: Loud thuds and slow, deliberate scratching typically occur at night as raccoons move through walls or ceilings.
    • Mice and Rats: Small, quick noises after dark, combined with chewing or scurrying in hidden spaces, often indicate the presence of these agile rodents.
    • Squirrels: Short, rapid bursts of scratching are usually heard during the day in walls or attic areas as squirrels move about.
    • Carpenter Ants: Gentle rustling or light tapping sounds may come from wooden beams or structural areas where carpenter ants are active.
