The Top Three Squirrel Repellents & Traps

Preventing squirrels from invading your loft or roof space, or outside in the garden, can be made a lot easier using an electronic squirrel repellent. Fending off squirrels is not easy. They are resourceful creatures and quite intelligent. They seem to love solving puzzles and will find all kinds of ingenious ways of getting to a bird feeder, for example.

Wild squirrel running away from repellentOur favorite bit of kit is the RODAR II Ultrasonic unit. You can pick it up for under $90 if you shop around. Now, that may seem a lot to fork out, just to Ward off squirrels, but this device will work for a long time, keeping away the next generation of squirrels, then the generation after that, and so on.

The RODAR II Ultrasonic Pest Repeller is backed by more than twenty years of testing and perfecting by the company. It’s more powerful than its competitors, which means it can cover a greater area – 3,000 square feet, in fact. If you have squirrels living happily in your loft or roof space, they won’t be so happy once you switch this  on . You won’t hear a thing, but the squirrel will hear something akin to a jackhammer clattering continuously next to its ear.

You may feel, however, that $90 is too much for even the best repellent. That’s why we have reviewed two other products designed to do the same thing. One is a humane cage that will capture the animal unhurt, so you can release it far away from your home, and the other is a budget priced electronic pest repeller. We haven’t provided as much detail in these other two reviews as we have in the main one, but we feel it will help you to make the buying decision that is right for you.

What should you look for in a deterrent?

You may have a different view on the matter, but these are the main points I looked for when I shopped for a repellent:

  1. A long range – it needs to be able to repel animals quite far away, as well as those close to the unit.
  2. Power – it needs to have plenty of power to be able to blast out its ultrasound message.
  3. Silence – it needs to be silent for me, but screaming something really irritable for the squirrels.
  4. A long AC cord – I don’t want to have to resort to using an extension cable in order to place it where I need it.
  5. The right size – it needs to be large enough to keep squirrels at bay, but small enough to fit into  small awkward places.

#1 – Our Top Choice – The RODAR II Ultrasonic Unit

See what the RODAR II looks likeThe main thing I like about this product is the fact that the squirrels are not harmed in any way. They may have to suffer some discomfort with the noise, which I understand sounds to them like a jackhammer blasting away next to their ears, but they know to quickly move away to somewhere quieter. Hopefully, that will be somewhere that is not in my house.

The squirrels come into my attic, loft or roof space because there are spaces and gaps that let them get in. I really need to fix that! In the meantime, however, they come in to the house because it is warm and it’s a good place to make a nest and raise a family – from their point of view. They may also have discovered a food source too, so you can’t really blame them for taking up residence. You would too if you were a squirrel.

Removing squirrels from a home is not easy. You can lay down poison, but that is revolting. The creatures suffer before they die, and your family pet, or worse still – your child – may get mixed up with the poison, with disastrous results. You could set traps, and humane traps work well, but simply introducing a device that squirrels can’t stand the sound of, but you and your pets can’t hear, is even better!

That’s what the RODAR II Ultrasonic Squirrel Repellent does. It simply drives the squirrels – and mice, and rats, and whatever else you have lurking around the house – away. These creatures prefer a bit of peace and quiet, by and large. They don’t like living on what sounds to them like a building site, so they simply move away unharmed, probably to annoy your unsuspecting neighbor …

What makes the RODAR II so effective?

In a word, power. The RODAR II Ultrasonic Pest Repeller can effectively cover an area of around 3,000 square feet. To get an idea of exactly how much that is, it’s over 20 generous sized rooms of 12 feet by 12 feet each. That’s a lot of space, so you see, the RODAR II doesn’t have to be close to the squirrel to repulse them. They can be relatively far away and still be repelled by this product.

The transducer of this repellent broadcasts ultrasound in the 23 to 55 kHz range. Other sonic products may also use this range, but they tend to lack power. There are often preposterous claims, but the RODAR II has been tested to have over 60 times more power than its competitors. That’s what makes all the difference.

Its efficiency is even more enhanced when you consider you don’t have to clean up after it. There are no dead bodies to dispose of, no blood and gore, no deadly poison with its inherent risk – and no squirrels either! It’s simply a case of place it where you think it will be most effective, switch it on, and leave it to drive the squirrels away. It couldn’t be easier or cleaner.

How does the RODAR II work?

The idea behind this product is simple and very effective. You see, we humans can only hear things within a certain range. Other animals can often hear thing outside of that range, which means they can hear things we can’t. Takes dogs, for example. Most people know that ultrasonic dog whistles work because the dog hears it just fine, but we humans do not. It seems the dog is reacting to nothing at all, but he can hear a high-pitched whistle that we can’t.

This is how the RODAR II works. It produces a sound in the 23 to 55 kHz range that is extremely irritating to the animals that can hear it. It has been likened to a jackhammer thumping and clattering right next to your ear – constantly with no let up. No wonder then that creatures like rats, mice, and of course, squirrels, hate the sound. They can’t stand it, which is why they move away. They want an easy life, after all, and putting up with a clattering jackhammer all day and all night is not their idea of the good life. That’s good news for us humans though, who would rather live without squirrels in the attic.

I should add that the range used by this Ultrasonic Pest Repeller is a range designed to be heard most strongly by rodents in particular. If you have pets, a cat or dog, they will not be affected by the sound. It would rather defeat the purpose if your dog or cat left with the squirrels, wouldn’t it?

The other good thing about ultrasound is, although it’s there, but you can’t hear it, it has no ill effects on you. It doesn’t have a long-term dangerous effect, it doesn’t make you nauseous, it won’t give you a headache, or cause cancer – in short, it’s perfectly harmless. This means the RODAR II is completely safe to use, even if you have a baby in the house. You won’t hear it, but you will get shot of squirrels when you use it, just like I did.

Is there any maintenance associated with the RODAR II?

To be honest, no. The device is smaller than most people expect it to be. This is a good thing as it means it will fit into small spaces where squirrels may be. It measures 5.6 inches tall, by 4.2 inches wide, by 3.5 inches deep. It looks a bit like a small loudspeaker cabinet, which I suppose it is in a way.

You can clean the housing with a damp cloth if you like, but you don’t have to. You can even polish it a bit if you want, but it isn’t really necessary. It’s an electronic device, so treat it in much the same way as you would treat any other electronic device. Don’t leave it out in the rain, or in direct strong sunlight, for example, but other than that, the RODAR II pretty much looks after itself.

What are the main features of the RODAR II?

These are a few of the main features:

  • It is designed to get rid of pests such as rats, mice, bats and squirrels in particular.
  • Its small size makes it unobtrusive and ideal for practically any room of the house, as well as a garage, shed, office, basement, etc.
  • It is very powerful, up to 60 times more powerful that competing products.
  • It can effectively cover an area of up to 3,000 square feet.
  • It is safe to use where you have non-rodent pets.
  • It has no batteries to replace.
  • It uses a standard AC plug outlet, and it comes with a long cord, making an extension lead unnecessary.

What do customers think of the RODAR II?

User feedback is very important to anyone thinking of buying any product. The reviews provided by ordinary people who have already bought the product are invaluable when it comes to making a buying decision. The RODAR II Squirrel Repellent has a number of customer reviews, especially on Amazon, and by and large, their opinions of the product are positive.

There are 11 customer reviews on Amazon, at the time of writing, and they have voted the RODAR II Ultrasonic Squirrel Repeller 3.7 stars out of 5 stars on average. One customer was obviously pleased with his purchase when he wrote, "The day I placed the Rodar II in my attic was the last day I ever heard of Mr. Squirrel."

Customers of the RODAR II liked these features:

  • The AC adapter is fairly long.
  • It has a reasonably long AC power cord too, so you’ll likely not need an extension cord.
  • It is well worth it, especially considering the 3000 sq. ft. coverage.
  • The unit is practically silent. You can faintly here a very very light clicking, but in my attic, it’s all but forgotten.
  • This unit, the Rodar II, totally got the job done. I’m impressed.
  • The squirrels left the attic very quickly (within an hour it appeared) and have stayed away.
  • I don’t know where they all went but I haven’t seen any in at least 2-3 months.

There were a few negative points you should be aware of too:

  • This is one of the most expensive units in the category. Yes, but in my opinion, that merely reflects the quality and effectiveness of this product.
  • It was very big disappointment to see that rodents are completely ignoring it (from few feets away). The RODAR II has been extensively tested in field conditions, and it certainly does work. It is more than likely that the particular model the customer was referring to was faulty in some way.
  • I decided to move the Rodar into the room with the problem, and last night I saw one walk right past it and not effect. Again, this customer should have tested for faults first, and not assumed that the product doesn’t work.
  • I did talk to an pest control guy and he said that for the most part they don’t work otherwise he would be using them. I wonder why the "pest control guy" said that? Could it be that he wants this customer’s work? I mean, if he praised these devices as being wonderful and effective, no one would need a "pest control guy," would they …
  • I could tell that mouse are a little quiet than before since RODAR II plugged in two month ago, but several are still there, just no happy feet any more. Now I wish the product is more powerful to get rid of those bad guys completely instead of cooling them down. Once again I strongly suspect that the unit in question is not realizing its full potential.
  • The Rodar II is more expensive than the other ultrasonic products out there. And it includes incredible quality, as mentioned before. Don’t expect this level of quality and effectiveness for giveaway prices.

A quick summary of the RODAR II

It is a small electronic device that emits an ultrasonic signal in a range that rodents find intensely irritating. The sound can’t be heard by most household non-rodent pets, or humans. The sound has been described as sounding like a jackhammer clattering constantly alongside your ear. This is why it is very effective at driving squirrels and other rodents out of a house.

The unit is a bit expensive to purchase, but it typically has a very long life as it has no moving parts to wear out. In addition, it covers a very large area, around 3,000 square feet, which is enough to cover most houses. The RODAR II Ultrasonic Squirrel Repeller is also more powerful than similar competing products, and has been tested to be more than 60 times as powerful.

  1. Mark,
    We are having problems with squirrels on our very old and gorgeous 160 year old Live Oak Tree… Now they are chewing around the branches (eating the bark???) and now we have rather big branches death….!!! Please let us know what is effective to get them out of the tree. Thanks,
    Gloria

    • Hi Gloria

      The good news is that it is relatively simple to trap a squirrel which has taken a liking to your trees.

      Then click the link to read the article on What Is the Best Squirrel Bait:

      Remember to release the squirrel, in a suitable spot, a couple of miles from your home so it doesn’t find it’s way back to you.

  2. Hi Mark, we live on a 2nd floor condo with a balcony. The exterior walls of our building are brick. We have had a MAJOR issue this year w/squirrels climbing up the exterior walls and onto our balcony and causing a terrible mess, not to mention that they carry fleas, rabies, etc…. Our condo association has trapped at least 2 dozen squirrels, from various balconies, and relocated them; there are still a few stragglers remaining… we tried the fox urine pellets and they had been working until today. Would the RODAR II work if we plug it in and put it outside on our balcony? we have tried the cheap units to no avail. We also have 2 closets on either side of our balcony, with electricity, so we could put the unit in one of the closets if you think that would be a better solution.

    • The Rodar II will work best on your balcony if your balcony is at least partially enclosed, that is, if you have an overhang or a roof. Don’t put out the Rodar II where it is exposed to rain and snow.

      The best way to use Rodar units is (1) to put them at one end of the balcony, so initially squirrels will favor one side of your balcony over the other and (2) to use them intermittently rather than all the time. If you run your Rodar unit 24/7, squirrels will eventually just ignore it. If you leave it on during the day and turn it off at night, when squirrels rest, it may be more effective.

      It is especially important that your roof and attic are completely sealed so you don’t suffer a squirrel invasion inside your home as well as out. Usually this is the responsibility of the condo association, but check your agreement and be sure your roof and attic are squirrel-proof. You don’t want to drive squirrels off your balcony and into your attic.

  3. Hi Mark- I was thinking about purchasing a RODAR in a effort to get the squirrels in my roof to leave, but I don’t have an attic, so no big open area- there are just the spaces between the ceiling joists. The little critters are getting in through vent holes around the bottom of the roof line which I planned to cover with metal screen after they vacate. since you stated in an earlier post that this will not work through solid objects, it sounds like this is not the solution for me. Am I mistaken? Do you think it would work in this situation?

    • So, I assume you have a flat roof? If you have space to sit the Rodar on top of a rafter then you can’t use it. I should seal up you vent holes sooner rather than later and perhaps leave one open for a day before sealing that one up or put in a one-way flap/door.

  4. Kelli DeGarmo says:

    Hello Mark. A friend has an issue of squirrels getting under the hoods & bumpers of vehicles. They chew through wiring & such generally making a mess of things & causing problems. I was going to recommend he get a RODAR but since the unit is not made to go outdoors, do you have any other recommendations? If he placed the unit in his garage, would the sound be able to reach outside to repel the squirrels our would the garage door block the sound? If it would effectively repel the squirrels from the vehicles parked in the drive, would the frequency bother the pet rabbit they have in an interior room next to the garage? Any assistance you can provide would be much appreciated. Thank you!!!

    • Probably the RODAR unit would not deter squirrel traffic outside the garage, because you need to have bristles or rubber flashing at the bottom of your garage door to keep animals out, and this also keeps sound in. To keep the car in the garage squirrel-proof, you have to be sure to close the door after the car is parked.

      For squirrels in the driveway, the best thing you can do is to deprive them of cover that allows them to move from trees to the car. Trim tree limbs that hang over your driveway, and remove creeping ground cover such as ivy or low-growing shrubs.

      Then you can make use of squirrel repellents – but where you put them is critical. A urine-based repellent will work if you put it on the tires of your car (especially the front tires, to keep squirrels away from the engine), and under your bumpers. If you put a urine-based repellent under the hood, however, it may repel you when you start the engine up!

      Pepper sprays, especially if they are made with habanero peppers, also repel rodents, but you don’t want to get a good whiff of pepper spray when you start up your car, either. Make sure not to use pepper sprays on any parts that heat up.

      If your climate permits, you could always place RODAR under your vehicles, powering it with an extension cord, but it is a lot simpler just to make the car a less desirable habitat, or harder to reach.

      Your friend’s bunny may have to be given other accommodations if you use RODAR near its hutch. Rabbits can hear sounds up to 42,000 Hz, and rats hear frequencies as high as 76,000 Hz. Unfortunately, it emits frequencies of 23,000 to 55,000 Hz, so it would disturb a pet rabbit.

      The way a rabbit lets you know it is upset is by becoming aggressive. Male rabbits fight with female rabbits, and mother rabbits kill their babies. Don’t let that happen. Make sure your rabbit is housed at least 20 feet (6 meters) away from any ultrasonic pest repellent unit, on the other side of a solid wall.

  5. Hi Mark,
    we were on vacation a couple of weeks, and a rat made a nest inside our corolla car in the driveway and chewed through wires that were connected to the engine. ( for throttle/pedal position sensor )
    I want them not to come back so we don’t have to get our car fixed again.
    I do not want to trap them, I want an ultrasonic device that works -outside the house- to keep them out of the driveway and our cars.
    we have a small 1400 square foot home on a 5000 square foot lot with similar lots across the street, behind and on either side of the house for blocks.
    also people walk their dogs and some (non-feral) cats walk the neighborhood so I don’t want to hurt others’ pets. We have no pets.
    What product should we buy? It sounds like the rodar II is only for problems inside the house, not outside.
    Everything i see is either
    1) for inside the house only, doesn’t work for us
    2) scares away dogs and cats, I don’t want to cause discomfort to dogs and cats

    Thanks,
    Mike

    • Hi Mike, thanks for your question. If you were to use an ultrasonic unit, we would recommend “the Herding method” but as your car is outside this won’t work. Seeing as this is such an interesting question, I have written a full answer in our FAQ. You can read it by clicking here.

  6. Hi Mark,
    I have six fruit trees, one next to the other in a small yard. Part of the small yard is covered and I have a table and chairs there. Can I use this device outdoors, given that I will protect it from rain and sun? I mean, is this device effective outdoors or it only works effectively indoors?
    Thanks,
    Ranna

    • Hi Ranna,

      This is what the supplier says:

      “I would only place this in a weather proof space. The weather elements may make your warranty null and void. This works though.”

      Kind regards,

      Mark
