What is the best deterrent for rats?

Essential oils are some of the best natural rat repellents. Rats have a highly developed sense of smell, which makes strong odors such as pine oil, cinnamon oil, and even peppermint oil offensive to them. Cayenne pepper, cloves, and ammonia will keep rats away as well.

Piles of tiny droppings, scratching noises in the walls, tiny footprints on a dusty shelf, and holes chewed through food containers are all telltale signs that rats have taken up residence in a home. While poisons and traps are effective means for offing these little pests, lethal solutions aren’t always feasible for households with pets and children. Rat repellents offer a solution that’s safer, all natural, and more humane. These products are either scent-based or sound-based solutions. Pellets, packets, and sprayers drive rats away by emitting strong odors that do not bother humans but that rats can’t tolerate. Ultrasonic repellents emit sound waves that humans and pets can’t hear but that cause rats auditory distress. This guide will outline the advantages and disadvantages of these nonlethal rodent remedies and recommend the best rat repellent products for your property.

What to Consider When Choosing the Best Rat Repellent

Ahead, discover the pros and cons of ultrasonic and scent-based rat repellents and learn about the important considerations—including coverage and longevity—that shoppers should think about before purchasing one of these humane pest solutions.

Type

There are two types of rat repellents: scent-based and ultrasonic repellents. Scent-based products are sold as sprays, pellets, or packets. They work by dispersing a strong smell, usually peppermint or pine, that rats dislike. Liquid sprays are applied to areas where rats enter the home, such as doorframes, windows, cracks, and crevices, leaving behind an oily residue. Packets are small pouches of dry ingredients and are ideal for positioning around the exterior or interior of a home. Pellets are infused with a mix of nonessential oils and other odiferous ingredients. With pellets, users can fine-tune how much of the product is distributed—a sprinkling of pellets in smaller spaces, such as a drawer or cabinet, and larger quantities in a garage or bedroom. Ultrasonic pest repellents use sound to send rats packing. Their sound waves are inaudible to humans but irritating to rats. Indoor ultrasonic devices are plugged into a standard wall socket and are similar in size to a plug-in air freshener. Ultrasonic waves cannot penetrate walls, so more than one unit may be required to treat an indoor infestation. Purchasing enough of these devices to treat an entire home could be costly, depending on the size of the home. Outdoor ultrasonic repellents are essentially small transmitters that are attached to stakes and powered by a solar cell. Users drive these stakes into the ground just as they would solar walkway lights. These devices typically cover a radius of about 40 feet.

Ingredients

Scent-based repellents use natural ingredients—typically aromatic essential oils, such as peppermint, cinnamon, spearmint, and balsam—to drive off rodents. While the scents from these oils are offensive to rats, most homeowners rather like them. In a way, these fragrant oils sort of double as air fresheners. Packets and pellets use dry forms of these oils, while sprays typically dilute the liquid forms. Unlike rat killers or mothballs, scent-based rat repellents don’t contain harsh chemicals or poisons, making them safe for use around humans and pets. They’re also safe for the environment.

Coverage

Both scented and ultrasonic solutions have limited ranges. Scented sprays are only strong enough to cover the immediate area where the spray is released. Pouches are more potent and typically cover up to a 125-square-foot area. Pellets’ coverage ranges vary depending on how many pellets are used. A few pellets may be enough to treat a small closet, while a handful can create enough scent to protect a whole shed. Most ultrasonic waves can travel up to about 40 feet or until they encounter a structure or other solid object. Using an ultrasonic device to remedy a rat problem inside a home usually requires multiple units because these sound waves cannot pass through walls.

Working Time and Longevity

Rat repellents work fast. Scent disperses quickly into the air, and the irritant drives rats away almost as soon as they encounter it. Ultrasonic repellents begin to work as soon as they’re plugged in, and the sound waves carry to where rats are hiding. A household can expect results from rat repellents within days, if not hours. The length of time these rat-revolting products last has a lot to do with which product is used. Scent repellents eventually wear out but will continue to work after humans can no longer smell them. Expect them to be effective for 6 weeks or more. Rats have a more developed sense of smell than humans, which is why strong odors such as mint and pine are so offensive to them. Though ultrasonic devices may cost more at the outset, they will last much longer because they rely on electricity or solar power to relay an audio tone—there’s no product to run out of. Ultrasonic repellents can last for several years before they wear out.
