If used for preventative reasons, they may work well to keep rats and mice away. Most of the all-natural or DIY methods used to prevent mice are said to work because rats are repulsed by their smell. This is especially true for dryer sheets—while these smell wonderful to us, they are abhorred by rats and mice.
Other university studies demonstrate the effectiveness of dryer sheets to repel certain insects, including mites, food-infesting beetles, German cockroaches and weevils. These studies, however, do not show any significant impact as a mosquito repellent.
Dryer sheets are often used to make clothes smell fresh and clean. They also work great for repelling squirrels! The strong scent of dryer sheets will keep squirrels away. You can place them around your property or add them to a bag and hang them in areas where squirrels are active.
Another strong smell that will discourage mice from your home is dryer sheets. Place fresh ones around mouse hangout points, or stuff them into entry holes. Same thing here, though: make sure to remove them once the smell wears off. Nothing looks nicer for a nest than an unscented dryer sheet.
While Bounce dryer sheets certainly may help initially rid you of a mouse, they will not solve an infestation or be a reliable long-term solution.
Most dryer sheets contain the ingredient linalool, which can be found in plants like lavender, basil, and coriander, all of which naturally repel common garden pests. Similar studies found that this ingredient is also useful for repelling bugs like mites, weevils, beetles, and German cockroaches.
As it turns out, there are several smells that these pests cannot stand, which means you can use them to your advantage. But what exactly do mice and rats hate to smell? Mice can be kept away by using the smells of peppermint oil, cinnamon, vinegar, citronella, ammonia, bleach, and mothballs.
Mothballs - Contain naphthalene and may deter mice when used in strong enough doses. Ammonia - Mimics the odor of predators' urine and can act as a repellent. Peppermint Oil, Cayenne Pepper, or Cloves - Have strong scents that may repel mice.
"Some smells repel mice for a short period of time, like cigarette smoke and certain colognes," says Ron Harrison of Orkin Pest Control in Atlanta. Therefore, the Bounce dryer sheets might work for a day or two, but then you're just likely to have chewed up dryer sheets!
Fact: rats hate clean clothes. So do squirrels, raccoons, mice, and other rodents. Tuck dryer sheets under the doors of your basements, RVs, and garden sheds, to keep critters out.
Scents like white pepper, black pepper, and garlic are naturally unpleasant to a squirrel. The same goes for sweet smells such as peppermint. Try spraying your plants and flowers with water and then sprinkling on pepper or peppermint oil to deter squirrels.
I've never heard that dryer sheets create a threat or deterrent to wildlife. There's been a story going around for a few years now that claims the sheets contain large amounts of toxic chemicals that are harmful to human and animal alike, but that story has been pretty much debunked.
Dryer Sheets: Mostly False
Linalool is an alcohol derived from plants, and it gives dryer sheets their distinctive scent. In sufficient concentrations, linalool can indeed be used as a pest repellant, but your average dryer sheet doesn't contain enough of it to actually work on roaches.
The main thing I've learned is that dryer sheets seem to deter all kinds of pests. We told you before that you can use twist ties to attach dryer sheets to bamboo sticks to keep deer and rabbits out of your garden. A gardener suggested slipping dryer sheets under the straps of a tank top to keep bees away.
A: No. Mice are relatively smart, and even if the smell of this pesticide near their nest or in a trap bothered them, they would simply find a way around them. Besides, mothballs used outdoors could contaminate plants, soil and water.

Peppermint Oil
As a result, mice and others will avoid the smell. If you want something other than a pre-made peppermint-scented repellent, you can use scented cotton balls or create a water and peppermint oil spray.
Mice hate the smell of peppermint oil, cayenne pepper and cloves. You can try diluting these natural repellants in water and placing soaked cotton balls around the areas of your home where you frequently see mice, including under sinks and in drawers or pantries.
Mice won't disappear by themselves
Unless you change your habits to deprive mice of their food, wipe out the existing population and proof your property to stop them coming back, you'll always be sharing your home with disease-spreading, food-stealing mice.

They even said that after the sheets lost their scent, they used them for their intended purpose as dryer sheets. How cool is that? We love Bounce Dryer sheets for their lovely fragrance. So although mice hate this smell, your house will smell like the Great Outdoors.
The primary reason people suggest using dryer sheets is because of their intense aroma. Mice hate the smell and will do whatever they can to escape it.
Scare them. Dogs with free run of the yard are one of the most effective wildlife deterrents. Other scare tactics include noisemakers, motion-activated sprinklers or lights, and garden spinners or pinwheels.
Epsom salt
Sprinkle Epsom salts onto your trash can lid or around the areas that pests like to burrow into or dig around. Epsom salts will deter most any pests, including raccoons, mice, and squirrels among others.”
