Do Cockroaches Make Noise?
Surprisingly, yes. If you’ve ever wondered, “Do cockroaches make noise?” the answer is a little more complicated than you might expect.
Most of the cockroaches that invade homes don’t make loud, obvious sounds the way crickets or cicadas do. Instead, homeowners are more likely to hear soft scratching, rustling, or skittering noises as roaches move behind walls, under appliances, or through cabinets at night. According to pest experts, the sounds people associate with roaches usually come from their movement rather than actual communication.
Because cockroaches are mostly nocturnal, these noises tend to be more noticeable once the house gets quiet.
What Does a Cockroach Sound Like?
So, what does a cockroach sound like? The answer depends on the species and the situation. Although many homeowners never hear them at all, scientists have found that some cockroach species use sound during courtship or when threatened.
Homeowners who have roaches indoors often describe the sounds as:
- Light scratching or skittering in walls or ceilings
- Rustling inside cabinets, cardboard boxes, or pantries
- A faint fluttering noise from flying species
- Soft clicking, chirping, or hissing sounds
Large infestations can sometimes create a noticeable rustling sound simply because so many insects are moving around at once.
Even more interesting, different cockroach species may create different noises:
- American cockroaches can produce soft rustling or wing-fluttering sounds as they move. Learn more about our guide to American cockroaches.
- German cockroaches are generally quiet, although large infestations may create scratching noises behind walls.
- Brown-banded cockroaches tend to stay hidden in furniture and electronics, where movement may produce faint sounds.
- Oriental cockroaches are not known for making distinct noises, but their nighttime activity can still be heard in quiet areas.
- Australian cockroaches may create subtle wing sounds when disturbed.

Did you know that some cockroach species outside the United States, such as Madagascar hissing cockroaches, can make much louder sounds by forcing air through special breathing openings called spiracles?
Why Do Cockroaches Make Noise?
Cockroaches make sounds for a few different reasons.
In some species, males create noises during courtship or mating. Scientists call this behavior stridulation, which happens when an insect rubs certain body parts together to produce sound. Researchers have documented cockroaches making chirping noises by rubbing parts of their wings and body together.
Cockroaches may also make sounds when:
- They feel threatened
- They are competing with other roaches
- They are searching for mates
- They are flying or moving through tight spaces
While scientists have documented some surprisingly complex cockroach sounds, those behaviors are uncommon among the species most homeowners encounter indoors.
How Do Cockroaches Make Noise?
Unlike birds or mammals, cockroaches do not have vocal cords. Instead, the sounds they make come from physical movements.
Scientists have documented several ways cockroaches produce sound, including rubbing body parts together, tapping surfaces, flapping their wings, and forcing air through their spiracles. Researchers have identified these behaviors across multiple cockroach species, although most household roaches make only subtle noises that homeowners may never notice.
- Rubbing body parts together
- Scraping their wings against their abdomen
- Tapping surfaces
- Forcing air through their spiracles
- Flapping their wings during flight
When Do Cockroaches Make Noise?
Cockroaches are most active at night, so that’s when homeowners are most likely to hear them. If you’re hearing scratching or rustling after dark, especially in kitchens, bathrooms, laundry rooms, or basements, cockroaches could be one possible explanation. However, similar sounds can also come from mice, squirrels, or other household pests.
Hearing occasional noises doesn’t automatically mean you have roaches. Look for additional signs, including:
- Small droppings
- Egg cases
- Shed skins
- Unpleasant odors
- Live cockroaches, especially at night
If you’re noticing several of these warning signs together, it may be time to investigate further.
While cockroach noises are usually subtle, they can still offer clues about what’s happening behind your walls. And who knows? Maybe one day, homeowners won’t just be Googling “What does a cockroach sound like?” They’ll be pressing play.
