If you’re trying to attract rats, the right sounds can make a surprising difference.
Rats love 50 kHz ultrasonic calls. They use these high-pitched noises to share positive signals, like playfulness and bonding. These sounds really grab their attention and might even pull them into places they’ve never explored before.
Rats rely on their hearing a lot. That’s how they get around and talk to each other.
Most of their calls are too high for us to notice, but some noises—like movement or certain social calls—work well to draw them closer.
If you figure out which natural noises they like, you’ll have a better shot at managing or studying rats.
Since rats are social, they don’t just react to random sounds. They look for specific noises that mean friends, mates, or safety.
You can play recordings of these calls or even mimic rat movement sounds to attract them, and you don’t need food bait for that.
It’s a new way to interact with or control rodent populations. If you’re curious about the science, here’s some research on rat calls as species-specific attractants.
Noises That Attract Rats
Some sounds just naturally pull rats in because they mean safety, food, or company.
If you’re wondering what might make rats hang around your place, focus on noises linked to other rats, food, and shelter.
Sounds of Other Rats
Rats talk with high-pitched sounds, especially around 50 kHz. These “happy calls” mean safety and friendship.
If you play these calls or hear them, you’ll probably notice rats getting curious. The sounds tell them other rats are nearby, so the spot feels safer.
Both Norway rats and roof rats pay attention to these noises, even if there’s no food around.
Since rats like being with their group, these calls encourage them to come out. Some research suggests female rat calls might work best when you want to attract unfamiliar rats into new areas.
Food-Related Noises
Food noises grab rats’ attention too. Scratching or rustling near pet food or trash hints at a meal.
Rats quickly figure out these sounds mean food is close, especially in places like attics or kitchens where food isn’t stored well.
You might hear them chewing on packages or plastic containers. That’s a big clue they’re after food.
These sounds pretty much explain why rats break into homes or raid pantries during an infestation.
Shelter-Associated Sounds
Shelter noises, like soft scratching or movement inside walls or under floors, call to rats looking for a safe place.
You might catch shuffling or tapping, which means rodents are settling in.
Rats want quiet, hidden spots. These sounds tell them there’s a safe home waiting.
If you hear noises in your attic or ceiling, it could be roof rats or Norway rats making themselves at home.
Shelter noises often mean more rats will show up, making the problem worse.
Identifying and Responding to Rat-Attracting Noises
Rats make all kinds of sounds, and these noises can give away their location or what they’re up to.
You’ll hear them when they chew, move, or chat with each other.
If you listen for these sounds, you can spot rat activity early and do something about it before things get out of hand.
Gnawing and Chewing Sounds
Gnawing is probably the most common rat sound out there.
Rats chew on stuff constantly to keep their teeth in check.
You might hear scratching or crunching from walls, furniture, or the attic.
Look for these signs:
- Fresh gnaw marks on wood, wires, or plastic
- Shredded insulation or nesting stuff near chewed-up spots
- Rat droppings under the places they’ve chewed
If you hear gnawing late at night or early morning, rats are probably working on nests or looking for food.
Seal up holes and get rid of food sources to stop them. Fix any ruined insulation and stash food in sealed containers—it really helps.
Scurrying or Movement Noises
Rats stay busy, so you might catch soft scurrying, scratching, or rustling.
These sounds usually come from attics, behind walls, or under floors.
You can sometimes hear their paws or even hear them jumping between spaces.
Listen for these noises when the house is quiet. Scurrying mostly happens at night when rats go looking for food.
To keep rats away, clear out clutter and block off entry points. Cleaning up dropped food and sealing cans makes a difference too.
Vocalizations and Communication
Rats use high-pitched sounds to talk to each other. Most of these are ultrasonic, so we usually can’t hear them, but sometimes you’ll catch a squeak or a chirp.
They’ll make certain calls—especially around 50 kHz—to attract other rats or signal that everything’s safe. You might notice these happy or social calls bringing rats to a spot.
Researchers actually played recordings of these 50 kHz calls near bait boxes and saw more rats go inside. It’s pretty wild that a sound can lure them in just like food.
If you’re hoping to keep rats away, you really shouldn’t play sounds like this near your place. Stick with traps or repellents and make sure you block off any spots they might use to get in.
