Rodent Defense Spray Review

If you’re looking for a completely natural chipmunk repellent, then this spray from Exterminator’s Choice is what you need to keep small mammals away from your property. One reason why this rodent repellent is in our top 3 list is that it’s not poisonous to pets or humans.

If you want to keep chipmunks away from your property and yard naturally, Rodent Defense is a good choice. The repellent is made using a combination of natural substances that chipmunks and other rodents hate. This mixture of garlic, peppermint, rosemary, and pepper will keep critters from destroying your plants and property.

There’s actually some scientific proof that natural ingredients like peppermint oil deter small mammals. Some scientists observed peppermint oil keeping rodents away from areas treated with the solution. The fact that this spray also contains garlic (which is offensive to chipmunks) and pepper (which is an irritant) makes it the perfect product to keep chipmunks away from any fruit or vegetables in your garden.

Because the natural spray is non-toxic, it won’t kill the chipmunks. Instead, it humanely discourages them from coming near treated areas. This means that you won’t have the problem of removing small dead animals from your property.

Another advantage of using natural pest deterrents such as Rodent Defense is that you can safely treat indoor areas. So, if you’ve had to deal with a chipmunk invasion, you can treat your basement, attic, garage, and even your car to keep them from returning.

Many users of Rodent Defense by Exterminator’s Choice rate it as highly effective. Users have reported that they no longer have rodent-related problems after using this repellent. This natural spray repellent works on squirrels, rats, raccoons, and other small mammals. It will keep them away from garbage cans, flower beds, crawl spaces, and trees.


Bobcat P-Cover Urine Granules

What we don't like:

  • Must be reapplied at least weekly for it to be effective

Bobcat P-Cover Urine Granules Review

One way to scare unwanted pests away from your property, such as chipmunks, is to use the scent of natural predators. Predators mark their territory with urine. This is why, for chipmunks, a natural repellent that includes bobcat urine will be read as a clear sign of danger.

These bobcat urine granules from The Pee Mart are one of the best chipmunk repellents that use the scent of predator urine. The granules are long lasting, meaning you shouldn’t need to reapply them after a light rain. Because chipmunks are generally not city dwellers, the scent of bobcat urine signals danger for the little critters.

Some scientific evidence points to the face that rodents are scared of their predators’ urine. Researchers from Harvard Medical School reported that the urine of meat-eating animals has compounds in its scent that instinctively alert rodents to danger. This means that natural chipmunk repellents that include urine can help keep these little destructive animals away.

You can use urine granules to deter chipmunks by sprinkling them around the areas you need to protect. The good news is that although the smell deters chipmunks, the granules are biodegradable and won’t harm plants, the soil, or the environment. As with other natural rodent deterrents, using urine granules won’t kill chipmunks or other small mammals. So, you won’t have the added problem of having to get rid of any dead rodents you find in your yard.

We’ve included bobcat urine granules from The Pee Mart in our top 3 because the product has received good reviews from users. Users have found it to be effective at stopping rodents from entering their car engines, buildings, and greenhouses. It also stops them from destroying yards.

Another reason to consider purchasing this product is that, according to the manufacturer, it’s long lasting and 100% natural. Applying the dry urine granules is very easy, so you won’t have to worry about getting any urine on you or your clothes.


Apello Solar Chipmunk Repellents


What we like:

What we don't like:

  • May need multiple devices to cover a large yard or garden
  • Can take up to 2 weeks to be fully effective
  • May not work in all types of soil (e.g. sandy soil)

Apello Solar Chipmunk Repellents Review

These solar-powered Apello Rodent Repellent stakes use ultrasonic waves to effectively discourage critters from using your garden as their pantry. They are at the top of our list of the best chipmunk repellents because they require little maintenance, work effectively, and are simple to use.

Each unit sends sonic pulses and vibrations through the ground to stop chipmunks from coming into the area, sending 3-second pulses out every 27 seconds. Using these repellents means that you won’t have to worry about finding dead chipmunks or other rodents in your yard. They are completely non-toxic so they won’t pose any danger to children or pets.

When compared to other types of sonic-wave repellents, the Apello solar-powered stakes are the best on chipmunks, moles, gophers, and voles. These units have received good reviews regarding their effectiveness at deterring rodents and other small mammals. Users report that they prevent chipmunks from destroying vegetable gardens and small fruit trees. Because sound waves travel better in dense soil, these are more suited for use in yards and gardens with clay soil.

One of the main reasons for choosing this type of rodent repellent is that they’re virtually maintenance free. The units have built-in batteries that are recharged using solar power, so you won’t have the hassle of changing batteries. Each unit covers a radius of up to 45 ft. (13.7 m). There are 6 units in each package, which means you can effectively keep a medium-sized yard free from chipmunks for good.

Each unit is made out of durable, corrosion-resistant aluminum and will continue to work effectively – even on rainy days.

Shake-Away Rodent Repellent Granules use the natural scent of predator urine to help keep pests like chipmunks away from your vegetable patch, lawn, or yard.

Natural Armor All-Natural Animal Repellent

This non-toxic chipmunk repellent uses a combination of herbal scents, including peppermint and rosemary, to stop large and small animals from destroying your garden.

This Bonide Chipmunk, Squirrel & Rodent Repellent will drive away rodents of all kinds. Not only that, but it’s also completely natural. It’s made out of cedarwood, castor, clove, and peppermint oils along with sodium lauryl sulfate and water. Since it’s a natural product, it will last only about 6 hours after application, meaning that this won’t be a long-term solution to your chipmunk problem.

About Chipmunk Repellents

Chipmunk repellents are included in many different products designed to keep large and small animals away from your property. Animal deterrents generally use various mechanisms to scare off rodents and other small mammals. The most popular ways to deter chipmunks involve the use of offensive odors that the animal thinks taste or smell bad.

When it comes to finding the best chipmunk repellent to keep pests out of your yard and property, each type of deterrent has its own advantages and disadvantages.

  • Natural spray deterrents use strong natural smells to either scare away pests or make plants taste bad. Natural pest sprays have the advantage of not harming the environment. They aren’t toxic to pets or humans. You may need to reapply the repellent after rainfall, though. Depending on the size of your property, it can be expensive to use these natural sprays to keep out chipmunks.
  • Urine granules and liquids can be effective because most small animals rely on their sense of smell to alert them to danger. If they pick up the scent of a bobcat, coyote, fox, or another predator, the rodents will scurry away as fast as they can. It can also take trial and error to find the right scent to scare away the pests in your garden, though.
  • Ultrasonic pest repellents are often the product of choice for homeowners that want to protect a large area. Solar-powered ultrasonic deterrents need very little maintenance. They can stop damage to lawns, flower beds, and other areas where plants grow. All you have to do is place them at strategic places in your yard and switch them on. The feedback on the effectiveness of some ultrasonic devices is mixed, though. It may take trial and error to find the perfect one to use on chipmunks.

Who Needs Natural Chipmunk Repellents?

Many consumers who are concerned about the impact of chemicals on the environment look for natural ways to deter pests, such as chipmunks, rats, mice, and other animals. A 2013 report found that many pesticides designed to protect plants and crops find their way into the food chain. Using toxic chemicals to control pests also destroys the natural ecosystem, changing the natural microbial diversity.

Another reason to look for products that repel small mammals naturally is that these deal with pests in a more humane way. Setting traps that kill chipmunks leaves the homeowner with the problem of disposing of the dead animals. There’s also the risk that these types of traps could cause unwanted damage or injure pets.

Using repellents to keep chipmunks away from your property is necessary if you grow your own vegetables and flowers or don’t want your plants destroyed. There have even been reports of chipmunks burrowing under property foundations causing expensive structural damage! Natural repellents help create an unpleasant environment for chipmunks, squirrels, and other small mammals. They will then move on to greener pastures instead of destroying your property.

There’s another important reason to deter chipmunks from your property. Chipmunks, like most rodents, carry diseases. The journal PLOS ONE reported that chipmunks carry various diseases that they can pass on to humans, including Lyme disease.

Did you know?

If you notice one or two chipmunks around your property, it’s probably time to start deterring them. Chipmunks breed twice a year and can have up to 8 babies per litter. This means that you could up to 16 chipmunks living on your property within a year.

How Do Chipmunk Repellents Work?

How effective are the natural products that use odor to scare pests away from your yard? There are two types of products that are popular when it comes to rodent repellents: predator urine and offensive scents.

Chipmunk Repellent Natural Sprays

Just as certain smells are offensive to humans, there are certain odors and scents that animals dislike. The purpose of natural spray repellents is to cover areas with odors that will keep animals away.

Some sprays leave behind an unpleasant taste so that the critters will avoid the area. Other sprays irritate the animals’ nasal passages as they sniff around looking for something to eat.

Many of the natural animal deterrent sprays on the market are nontoxic. This means you can use them to repel animals from the fruit and vegetables that you will want to eat later on.

There’s actually some scientific evidence to suggest that these scent sprays are effective. Scientists have studied various scents to identify what repels chipmunks best. Research has shown that eucalyptus oil has a repelling effect on rodents. Other studies have revealed that rodents don’t like the smell of peppermint, wintergreen oil, or bergamot oil. Irritants like chili powder and black pepper can also send these pests scurrying away.

Urine Granules to Deter Chipmunks

Urine granules and liquid urine use the fear factor to keep chipmunks off your property. The scent of a predator’s urine can be a strong deterrent for small mammals who depend on their sense of smell to survive.

In some ways, urine granules work like the deterrent pest sprays. They create an environment that keeps small mammals from coming near. But it may take some trial and error to find a type of urine granule that works on the pesky chipmunks where you are.

For example, one study into the effects of predator odors to scare off gray squirrels found that not all predator scents worked the same. The researchers compared the odors of raccoons, deer, red foxes, and humans. In this experiment, the scientists found that raccoon and red fox urine were more effective than the other odors.

Electronic Chipmunk Repellents

The best part of using ultrasonic chipmunk repellents is that they won’t require much maintenance. Sonic waves and underground vibrations unsettle chipmunks, teaching them to stay away. You can also install ultrasonic repellents inside your home and vehicles to keep rodents from causing damage there.

Many homeowners have successfully repelled chipmunks and other critters with these devices, even though studies as to their effectiveness have been inconclusive. The University of Nebraska found that rodent repellents were effective in reducing pest numbers by up to 50%. Other studies show that well-placed ultrasonic devices are effective at getting rid of unwanted critters.

What Chipmunk Repellents Can These Natural Ones Replace?

Natural chipmunk repellents that use ultrasonic waves, offensive odors, or predator urine are effective ways to avoid using toxic chemical or inhumane traps.

In many ways, natural, eco-friendly deterrents are a better choice than their toxic counterparts. Some websites recommend using mothballs to prevent a chipmunk invasion. But mothballs may or may not deter chipmunks and other rodents. They also contain toxic chemicals that can poison our pets. There have even been cases of mothball fumes causing adverse reactions in humans.

What If Natural Pest Deterrents Don’t Work?

There is plenty of anecdotal evidence that shows that using electronic chipmunk repellents, natural sprays, and urine granules work for many people. They may not work in every case, though.

So, would you like to know some alternatives to natural chipmunk repellents? You could try putting humane traps around your property to help control the chipmunk population. These traps require constant maintenance. You’re also still left with the problem of releasing the chipmunk back into the wild, far away from your property.

You could also allow your cat or dog roam around your property, as a natural deterrent. This may not be an option for everyone, especially if there are animals that prey on pets in your area.

How to Use Chipmunk Repellents

To increase the effectiveness of chipmunk repellents, it’s important to use the product as the manufacturer intended. You will need to reapply most odor-based repellents at specific intervals, so you should check the instructions.

Most natural sprays and granules should be applied directly around the areas you need to protect. You can also soak old rags in the solutions and place them in perforated bags around the base of trees to keep chipmunks out of those trees.

You should place ultrasonic repellents at strategic places around your property to ensure total coverage. It may be necessary to check the charge of the solar batteries every 2 weeks or so, especially if there has not been much sunshine.

Chipmunk Repellent Buying Guide

What should you look for when buying these chipmunk repellents?

Natural Spray Repellents

To find the best natural spray repellent for chipmunks, you should read user reviews about the specific pest you want to deter. Look for products that contain peppermint oil, garlic oil, and an irritant such as pepper or chili powder. If you have a large area to cover, a large multi-gallon container is a very cost-effective option.

Urine Granules

If you want to try using urine granules to keep chipmunks off your property, then read user reviews to see if they have been effective on chipmunks. Certain predator scents may or may not repel chipmunks in your area since this will depend on the surrounding habitat.

Ultrasonic Chipmunk Repellents

The best ultrasonic wave repellents use weatherproof materials and are solar powered. Look for repellents that send out frequent bursts of ultrasonic waves. Some of the best units send out 3- to 4-second signals every 20-30 seconds. You also need to buy enough units to cover your property. So, it may be cheaper to buy a multipack with 4-6 units to cover your entire property.
