We can start with the one that’s been most effective when dealing with these hardy rodents and that’s targeting their sense of smell.

What Odours Do Rats Hate The Most

Rats have a very sensitive sense of smell. They use this to search for their food and communicate with their brethren. Just as rats have smells that they like, such as the smell of your garbage can or food that’s lying around the house, rats also have a lot of smells that they hate. Counteracting their presence with the odours they hate is the most effective way to deal with rats if they’re already present inside your home. Here are some odours you can use to repel rats from your household.


Mothballs are well known to repel a lot of households pests, including rats. Its strong, pungy smell is something that rats hate. However, mothballs are only effective when used in large quantities, which is harmful to humans. Use this at your own risk.


While peppermint is mostly known for relieving your stress from a hard day’s work, it also lessens your stress caused by rats as it’s an effective odour to keep rats away from your house. It’s much better than stacking large amounts of mothballs in your attic. Peppermint is all-natural, not toxic, and the smell is very welcoming to humans. You can increase the peppermint’s effectiveness by placing cotton balls with peppermint oil in the corners of the house and in the place where rats are frequently seen. 


Ammonia is a chemical that’s frequently labelled as a very effective rat repellant. The reason why rats hate the smell of Ammonia is that Ammonia is a chemical that’s also found in rat urine. If a rat goes near to something that it perceives as similar to urine, they might behave differently in that area because they believe it’s a territory of another animal. 

However, like mothballs, leaving containers of Ammonia open inside the house can be harmful to humans. Ammonia might cause slight dizziness and headaches to humans upon continued exposure to the odour of Ammonia. In addition to that, rats are very smart creatures wherein they will adapt to certain situations such as where the odour of Ammonia is coming from and avoid it altogether. 


This is the odour that rats hate the most. Rats dislike the smell of their predators, even if they aren’t found anywhere near the area. If a rat finds a place that smells like a cat, ferret, or raccoon, there’s a huge chance that the rodent will stay away from that site. According to a study in The Journal of Neuroscience, the stress hormones of rats increased when they were exposed to the odor of cats and ferrets. The rodents also showed defensive behaviors such as prolonged rearing, grooming inhibition, and avoidance of the item that reeks of predator scent.

Since the smell of rat predators can induce fear in these pests, keeping a pet cat may help in repelling mice. However, it’s also important to remember that rats can become aggressive when cornered. They can transmit disease-carrying parasites to the pet or seriously injure them while fighting back.

These are just some small steps you can take to ensure that rats won’t pester you. However, most of these are just temporary solutions to your major rat problem. To ensure that these pests won’t bother you anymore, here are other things that rats hate, which you can do almost immediately.

Rats Hate Their Needs Being Taken Away

Rats need three major components to get settled: food, shelter, and water. if you want to keep rodents out of your home, it’s important to block off their physical access to interior spaces by closing off any holes or gaps around windows or doors, through vents, in the eaves, or anyplace else around your home. Cut off access to any potential food supply by keeping your food in airtight containers in your pantry or refrigerator, rather than out in the open, and keeping any pet food in tightly sealed containers as well. Limit rodents’ access to water indoors by fixing any leaky pipes or faucets and dumping out any standing water that might attract them or encourage them to stick around.

You can also make your yard less appealing to rats and mice by cleaning up any fruits or nuts that drop from trees, positioning any bird feeders well away from your home, and keeping your trees, bushes, and other landscaping trimmed. Certain kinds of rats and mice are burrowing animals that build nests in the ground beneath overgrown shrubbery, and roof rats can travel from tree branches onto the roof of your home or garage if limbs aren’t cut back from the roofline, so a well-maintained yard can go a long way toward keeping rodent pests away.

Aside from being another food source, the vegetation in the yard also serves as a good cover for these rodents, which is why it’s important to regularly trim the shrubs and trees adjacent to the home. For roof rats that are excellent climbers, they can use the tree branches near the roof to get inside the attic and build a home there.

One more simple but effective way to keep rats away is to cover all the garbage bins at home. Leaving them unsealed is like inviting the rats to feast on the trash. It’s also important to keep them out of the sun to slow down the garbage decomposition and reduce the smell. If you still need to remove rats in Whitby, call our pest experts today.

Rats Hate Rat Traps

Since you’ve blocked the exits and entrances, you’re now going to need to catch these rats. To avoid any unnecessary accidents, aim to use non-lethal rodent catchers instead of snap traps which may cause more harm to you than the rat. Rather than exterminating the rodents, these traps actually keep them inside.

To attract the rats to the trap, use a combination of peanut butter, cheese, or anything that you found the rat was attracted to in your home. You’ll put these snacks for the rats in the cage component of the trap and once the rat enters, the cage closes behind it.

When you catch the rats, wear gloves when picking them up. These traps still have holes for them to breathe through, but this also means they’re likely to nibble or bite at you when you pick up the cage.

These are just some tips to help you out with your rat problem. Still, the best way to ensure your rat-related problems disappear is by hiring a professional rat control service as their expertise will help maintain the cleanliness and safety of your home.
