Smells That Squirrels Do Not Like

Squirrels can be adorable, but they can also be major pests, wreaking havoc in gardens and chewing on practically everything in sight. If you want to keep the frustrating rodents away from your property, you can often repel them through the use of various odors they intensely dislike.

Cider Vinegar

Squirrels object to the scent of cider vinegar, according to the Humane Society of the United States. Because of that, cider vinegar can be highly effective for keeping squirrels at bay. Simply immerse cloths in cider vinegar and place them in a key part of your home, such as the attic. You’ll need to replace the cloths with new ones whenever they lose their strength.

Spicy Odors

«Spicy» and «hot» smells can be helpful for deterring squirrels, according to Cindy Glokler of the «Times Union» in Albany N.Y. Squirrels simply don’t like them. White pepper and cayenne smells frequently discourage squirrels, for example. If you sprinkle your plants with flakes of cayenne pepper, it might keep unwelcome pests out of your garden. Squirrels also dislike garlic and black pepper smells. Raccoons share this aversion to the smell of pepper. To prevent the pepper flakes from blowing away, spray your plants with water before you put them on. Reapply as often as necessary. Fresh applications are also necessary after rain.

Distinctive Smell of Mothballs

The scent of mothballs might make many humans feel nostalgic for visits to Grandma’s house, but squirrels dislike the scent. If you’re experiencing a problem with squirrels inside or outside of your home, the use of mothballs might save the day, at least for a while. Be cautious, though, as mothball scent can also be highly bothersome to people. Repel squirrels by simply placing mothballs beside your plants or in household problem areas, such as the attic. Replace these mothballs when their smell begins to fade, every few weeks or so.

Skunk-Like Smells

Squirrels, not unlike humans, aren’t too fond of things that smell skunk-like. While you might not be able to bottle up the conspicuous smell of skunk to drive them out, you can depend on crown imperials as a substitute. The entire plant has an odor that’s reminiscent of skunks, so they deter squirrels, according to Marjorie Harris, author of «Ecological Gardening.» These plants thrive in the United States Department of Agriculture plant hardiness zones 5 through 8. Since the skunky odor is so strong, crown imperials can be highly effective for deterring squirrels from relatively far away — think several feet. Crown imperial bulbs can generally be purchased easily at many local garden centers.

Animal Urine

Squirrels dislike things that smell like animal urine, specifically animals that prey on them. Many squirrel deterrent products available at stores aim to mimic these odors. They generally come in spray form. As far as application and reapplication go, closely abide by the exact instructions on the product label. If a squirrel smells something that reminds him of urine from a daunting predator, it may think that something perilous is just around the corner, and it will try to avoid the area.

10 Smells that Cats Hate

Cats are the animal embodiment of cleanliness. These rules, which are natural and innate in them, don’t only apply to their personal hygiene. Rather, they are also applied to their environment and everything that has anything to do with them. Such is the case with smells, which is certainly an interesting topic within the feline world.

As a consequence of evolutionary processes, cats have their own respective olfactory preferences. Just as there are plenty of smells that they love, there are other smells that they simply cannot stand! Whether its food they can’t digest, strong natural odours or potentially dangerous chemical substances, a cat will avoid certain odours at all costs.

In this new Animal Wised article we have investigated 10 smells that cats hate. What other scents does your cat hate? We’d love to know!

We understand felines

Firstly, you need to know that cats have a sense of smell that is fourteen times stronger than that of a human being. This is because, even though it is not physically obvious, the nasal organ of each cat is much bigger than that of a human being.The cat’s olfactory system is distributed throughout its entire head, which gives them an amazing ability to smell.

Remember that cats, in this case, are also like people. There are some typical smells that are hated by the majority of cats, but even so, it depends on the individual. Some smells might be more repulsive to some cats than others. However, the following list is relevant for a large number of cats. Your cat, undoubtedly, could have a special sense of smell.

1- Citrus scents

Cats aren’t fans of limes, oranges, lemons and similar smells. In fact, there are cat repellents which contain smells such as these. If, for example, you’re trying to stop your cat eating all of the flowers in your garden, you can spray them with some orange oil or scatter the peel of some of these fruits around them. They don’t like the taste very much either, so it’s quite possible that they stay away from the area where they see a high presence of these elements.

2- Banana

Even though they are very tasty and high in potassium, cats don’t get on very well with this fruit. Rub the outside of a banana peel on the sofa, or leave it there for a day, if you don’t want your cat to have a nap there and leave their hair all over it.

3- Dirty litter box

Who likes to go to a bad-smelling bathroom? The same applies to cats when their litter box is dirty. Under no circumstances will they want to go near it. A dirty litter box could cause your cat to get angry with you and, as a way of getting back at you, make their own litter box on an expensive rug. Or, on an exotic plant and even on an item of clothing that has fell to the floor.

4 — Pine

Even though some natural sands comprise of this type of material (making it more pleasant for the cat in every sense), you mustn’t abuse the intensity of this smell. Doing so would have the opposite effect on the cat, to the point in which tit ends up hating the sand and rejecting it. By rotating the smells of the sand, and choosing more neutral-smelling ones, you’ll ensure that your cat doesn’t get fed up of them.

5- Poor condition fish

This is another similarity between cats and human beings. There is a huge difference between liking the taste of fish and liking the smell of it once it’s gone-off. Cats, just like humans, hate everything that is out of date. We recommend that you never give your cat out of date fish: firstly, because they won’t eat it, and secondly, because if you force them, they will get ill or you could end up poisoning them.

Other smells

6 — Pepper

Cats don’t appreciate the smells of spicy or heavily seasoned foods such as pepper, mustard or even curry. Their sense of smell perceives these as if they are toxic.

7 — Soaps and deodorants

Strong and chemical smells are rejected by cats. Be careful with the soaps and cleaning products that you get, both for cleaning the house and their litter box and food bowl. And even your personal hygiene products! Remember that odours attract or repel felines.

8 — Essential oils

Cats love most flowers and plants, they can interact with them without problem. Otherwise you wouldn’t have much of a problem keeping out of your garden. However, due to their strong sense of smell, they have problems with essential oils. They are too overpowering and can cause them to have quite a severe reaction. This is not to mention the fact that there are some plants which are toxic to cats. While smelling shouldn’t do them much harm, ingesting their leaves, flowers or even essential oils can.

9 — Eucalyptus

Most cats are averse to the smell of some plants because they are toxic for them. A typical example is their rejection of eucalyptus, since their essential oils can be harmful for the animal, and they know it. Nature is wise.

10 — Other cats

This rejection is the most interesting of all. Cats aren’t irritated by the smells of their cat friends or felines with which they come into regular contact with. However, the smell of a new cat at home could get on their nerves. Remember that cats are very territorial animals. We humans connect with other individuals through other means, whereas cats regularly connect through smell alone.

Top 10 Smells Dogs Hate

A dog’s sense of smell is completely different from a humans’, so it is not surprising that we have different tastes when deciding which fragrances seem pleasant and which aromas we consider unbearable. For us, the smell of urine and feces are some of the smells that repel us most. For dogs, these smells provide them with information which is of great interest to them.

Many of the smells dogs hate are found in our homes, producing discomfort in our dog’s nose, thus presenting our dog with an unpleasant environment. If you want to know what smells repel dogs, keep reading this AnimalWised article for more.

A dog’s sense of smell

Smell is the most developed sense in a dog. Dogs have between 150 and 300 million olfactory cells, a number that, compared with the five million cells present in humans, is colossal. This is why they are able to identify almost every particle in the air or on objects. A dog’s great sense of smell also allows them to determine exactly where these smells are located. For this reason, dogs are used to search for missing people, detect narcotic substances or even diagnose diseases such as cancer.

In addition, dogs are animals with a great smell memory. This means that, just as we are able to recognize a person through images, dogs are able to recognize us through smell. Therefore, it is essential to let an unknown dog smell you before you stroke them. This is also why you shouldn’t bother two dogs that are smelling each other.

Having such a sensitive sense of smell, it’s no wonder dogs are excited every time they go out on the street. An open environment such as this exposes a dog to a whole world of new smells to perceive and discover. Likewise, we should not be surprised if they show disgust to certain aromas that, for us as humans, may seem pleasant. Because of a dog’s strong sense of smell, what we may believe is not a strong odour, could be incredibly repellent to a dog. To find out what smells repel dogs, take a look at the complete list below.

Smells dogs hate — citrus

Humans tend to love the smell of citrus. Not only is it a lovely natural reminder of summer, but it is an aroma which can last for a long time. Therefore, we as humans often tend to buy products that contain citrus for a lasting fresh environment. However, our furry companions do not agree and this is one of the smells that dogs hate most.

Remember dogs have a sense of smell 40 times more developed than humans. Therefore, if the smell of citrus is already intense for a human, imagine how strong the smell of citrus is for a dog. It is such a strong aroma it can cause irritation in the animal’s respiratory tract, producing both an annoying and unbearable sensation.

Citrus fruits, such as lemon, orange or grapefruit, give off smells that dogs can’t stand. But, the scents that dogs hate the most are those provided by essential oils made with this type of fruit. Oils are concentrated products that emit a much more intense odor than the fruit itself. Therefore, animals perceive an even stronger odor than they would with the actual food itself.

If you intend to use a citrus scent to prevent your dog from urinating in a certain area of the home (such as the carpet), we recommend that you use natural fruits and avoid placing any oils within their reach. The purpose of this technique is to prevent the animal from approaching that specific area, not to offer an unpleasant coexistence.

While there are smells you can use to keep dogs away, it is important they are not harmful. This article on toxic fruit ad vegetables for dogs may be helpful.

Smells dogs hate — vinegar

Vinegar is another ingredient used as a home remedy to prevent a dog from urinating inside. Dogs hate the smell of vinegar. As with citrus fruits, the aroma of vinegar is so strong that it is somewhat unbearable for dogs. However, apple cider vinegar is actually beneficial for dogs. Therefore, depriving them 100% of it is also not advisable. We must learn how to use vinegar properly and know how often to apply it, so that our animal always remains as comfortable as possible.

Apple cider vinegar is highly effective in preventing your dog from smelling bad. However, since this is one of the scents dogs hate, we suggest mixing it with their usual shampoo to reduce its fragrance. Do not apply this solution to their head area and make sure to rinse them well after applying it.

Smells dogs hate — chili

Chili, or chili pepper is a food that owes its hot taste to a series of natural chemical compounds called capsaicinoids. In humans capsaicinoids are used from everything to flavoring chili and even help reduce obesity [1] . Dogs, however, are incredibly repelled by the natural smell of chili. So much so, that smelling this food directly can cause respiratory irritation, itching in the nose and constant sneezing in a dog. It is therefore essential to know which human foods are banned for dogs to prevent them from consuming them.

Smells dogs hate — alcohol

Antiseptic alcohol is a smell dogs don’t like. We completely discourage applying alcohol to a dog’s skin. In case of injury, the best thing to do is to clean the wound with water and go to the vet so that he/she is the one to disinfect it. If you are in a situation in which you cannot go to a specialist, we recommend consulting the following article in which we discuss how to make natural disinfectant for dogs and apply it by following the instructions.

A dog’s reaction to this will depend mostly on the alcohol content of the disinfectant. In addition to this, dogs hate antibacterial gel agents and some alcoholic beverages. This is not the case for all of them. A dog may try to drink a beer or a cocktail which it otherwise thinks is tasty. Remember, even if we cannot necessarily smell much, they can smell everything.

Smells dogs hate — nail polish

The smell of nail polish can be pleasant for many people, but dogs detest this smell too. Nail polish is made up of a high number of chemical compounds, so it is not natural. They include formaldehyde, nitrocellulose, isopropyl alcohol and acetate. Dogs hate the smell of these fragrances. If a dog comes into contact with nail polish it can also cause them to sneeze and itch excessively.

On the other hand, nail polish removers also form part of the list of smells that dogs hate. This is due to their chemical compounds, the scent of acetone being perhaps the most annoying smell of all for dogs. We recommend opting for acetone-free nail polish remover and/or keeping all of these cosmetic products away from dogs.

Smells dogs hate — chlorine and cleaning products

Although for us they produce a fresh and clean ambiance, dogs hate the smell of cleaning products. Not only do dogs not like this smell, but these products are also highly harmful and dangerous for dogs. Inhaling these chemicals directly can cause irritation of a dog’s respiratory tract and esophagus. In addition, ammonia produces an aroma very similar to that released by a dog’s urine. A dog will then associate this ‘urine’ smell to the presence of another animal at home and it can cause stress in dogs.

Although the above mentioned products are considered the most annoying products for dogs, they generally hate the smell of all cleaning products. Many cleaning products are given scents such as citrus which the dog would hate anyway. If you need to clean the house, we recommend trying to clean the house while another family member takes the dog for a walk. This will avoid placing your dog in an unpleasant environment. Enzymatic cleaners are the best to use if you have a dog in the house. Many don’t even use scents, so they are unlikely to repel your pet.

Is naphthalene toxic for dogs?

Yes, naphthalene is toxic for dogs. Naphthalene is generally used as a pesticide, due to its high level of toxicity. No only do dogs hate the smell of this chemical, but if ingested it can kill your dog. The ingestion of a single naphthalene ball can cause serious damage to a dog’s liver and central nervous system. The result is vomiting, diarrhea and convulsions. You will need to take them to the vet to counteract this action, otherwise it could be fatal.

Do dogs like the smell of perfume?

No, dogs hate the smell of perfume. Have you ever noticed that, after perfuming yourself and trying to hug your dog, he or she rejects you? This is because perfumes are products made with a great amount of chemical compounds and scents that dogs hate.

In addition to the unpleasant smell, dogs also hate the smell of perfume because it camouflages the smell their owner’s natural body odor, a smell that comforts them. Remember that dogs recognize us by our smell, if we hide it under another one, it is not surprising that they will naturally detest that unpleasant fragrance that prevents them from identifying us.

What about dog perfume? yes, dogs also don’t like this smell. However, as long as they are of: good quality, are not harmful and are specifically manufactured for dogs, you can apply them in moderation.This means that we do not recommended putting perfume on your animal every day, but once in a while; as a canine hairdresser would.

As with humans, every animals has a taste of their own and therefore may not find all of the smells mentioned to be unpleasant.

What Smells Do Woodchucks Hate?

Marmota monax, commonly known as woodchucks or groundhogs, are rodents closely related to squirrels. To gardeners, woodchucks are destructive pests that are known to dig burrows and eat vegetables before they can be harvested. The woodchuck has a highly sensitive sense of smell and can be deterred with odors it finds repellent, and there are a variety of smells that can do the job.

Cayenne Pepper/Garlic

The taste and smell of powdered cayenne pepper can prevent a woodchuck from eating your plants. Simply sprinkle a liberal dose of cayenne pepper on plants and in your garden dirt to repel woodchucks. Although rain reduces cayenne’s effectiveness, there are products that suspend hot pepper in a wax, which is applied directly to plants and will not readily wash off during rains. Leaving sliced hot peppers in the area also can prove effective. Groundhogs also find the smell of garlic, either raw or in powder form, repellent.

Castor Oil

Castor oil is another smell groundhogs hate. Many garden supply stores sell various castor oil sprays to repel groundhogs. The Urban Nature Information Service of McGill University recommends mixing a solution of 1 cup of castor oil with 2 cups of Murphy’s oil soap, 1.5 cups of ultra-hot, hot sauce and a quarter of a shot glass of human urine. This should be diluted with water, 1 teaspoon per gallon, and sprayed around the garden or groundhog-infested area.


Groundhogs can’t stand the smell of ammonia and immediately leave a burrow tainted by it. One common form of repelling groundhogs is to leave ammonia-soaked rags around the garden and to throw mothballs into burrows. Another way to accomplish this is with kitty litter. Instead of throwing away used kitty litter, pour this ammonia-rich mess into burrows. Ammonia, however, is a toxic substance that may be dangerous to the animal if ingested.

Rotten Eggs/Predator Urine

The powerful smell of rotten eggs is naturally repellent to woodchucks, just as it is to humans. One method of keeping a garden free of woodchucks is to break eggs in the holes of their burrows and let them rot until the smell becomes apparent and woodchucks flee the area. Another scent that makes woodchucks run is the urine of a predator, such as a wolf or coyote. Coyote urine is sold in many garden supply stores and should be sprinkled around the garden or other areas where woodchucks are a problem. The smell of both rotten eggs and predator urine, however, will dissipate over time and must be refreshed frequently to maintain potency.

What Smells Can Birds Not Stand?

by Rachel Monroe

Birds dislike the smell of hairspray, perfume and after-shave—they can be toxic.

While birds possess olfactory glands glands, enabling them to smell, they do not rely on this sense as much as humans or other animals. Birds primarily use their sight and keen sense of hearing to find food and detect predators. However, there are a number of scents that may not only be unpleasant for your bird—but are also downright dangerous.

Put it Out

If you enjoy cigarettes or cigars, avoid smoking around your pet bird. Second-hand smoke is detrimental to your bird’s health and is a source of irritation to him. Some birds will begin feather plucking because they dislike the smell of second-hand smoke on their feathers. This habit can be difficult to overcome, even if smoking in the home is eliminated. Second-hand smoke contains 4,000 chemicals, including 69 cancer-causing substances. Smoking around your bird can damage his lungs and respiratory tract. If your bird finds a cigarette butt and eats it, it could cause nicotine poisoning. Nearly 25 percent of the nicotine in a cigarette is found in the butt. Symptoms of nicotine poisoning include panting, vomiting and increased heart-rate. Never smoke around your bird or his cage.

Can You Smell That?

The smell of scented candles, aerosols sprays and air freshener wall plug-ins can be deadly to your birds. Many of these products, particularly the plug-ins contain a high concentration of essential oils, which can irritate your bird’s eyes, throat and nostrils. In some cases, they may also suppress the central nervous system, causing death. Use cinnamon sticks or orange peels to create a pleasing aroma in your home without threatening the comfort of your birds. Open windows to let in fresh air. Some candles contain petroleum products. Although they may smell refreshing to you and your family, they are the equivalent to the smell of burning rubber for your bird.

Remodel Safely

If you are painting the interior of your house or remodeling, ask a friend or family member if your bird can stay with them for a few days. The smell of paint, glue and other chemicals are hazardous to your bird. They could damage the respiratory tract or cause death. Particle board and plywood are fortified with formaldehyde, releasing this smell into the air. New carpet, varnish and lacquer can emit volatile organic compounds, including formaldehyde. The smell of this compound causes headaches and nausea in humans—consider how it could affect your bird.

Cooking it Up

Your kitchen can let off the worst smells and deadliest fumes for your pet bird. Avoid using non-stick cookware. These accessories contain PTFE—a harmful chemical which emits a deadly toxin into the air. The toxin rapidly destroys your bird’s lung tissue, causing them to suffocate. A variety of cookware contains PTFE, including pans, grills, skillets, oven drip pans, coffee makers, popcorn makers and waffle irons. Safer alternatives include cookware made from stainless steel, copper, glass or aluminum.
