One of the safest and natural ways to get rid of a mouse is peppermint oil. It can be used both indoors and outdoors and recognized as one of the most effective methods. Take several cotton balls and put a few drops of the oil on each of them. Then leave these balls near the places where you have seen mice and where you suppose they live. The disadvantage of this oil is that it dissipates quickly, so you need to change cotton balls with fresh repellent several times a week.
Mothballs are also considered to be an effective mouse repellent. You need to take them from the box and place in the area where mice live. Make sure that no pets or children will have access to these places. They must never be used in non-ventilated areas since they can be very dangerous. Accidental ingestion of mothballs by children or pets will lead to heavy sickness and in rare cases even death.
Mouse deterrent spray
Unfortunately, there is no scientific evidence that any mouse deterrent spray available on the market is effective. This happened because there are no government regulations or requirements regarding this type of product, i.e. there is no need to prove that it is effective before it goes to the market. However, even trusted e-commerce websites advertise a different kind of mouse deterrent sprays. In most cases, these products are sold as an effective way to get rid of mice. However, they just irritate rodents for a couple of seconds with the help of natural oils and other chemicals, so will not help you to get rid of them once and for all, simply because mice are adopting to them fast.
Ultrasonic mouse repellers
Ultrasonic mouse repellers are devices which use high-frequency or ultrasonic noise to repel and shoo all pests, such as rats and mice which are usually living at home. Homeowners vexed by mice are often interested if ultrasonic repellers are really effective and able to help them to get rid of mice.
These devices use ultrasound, which has a frequency of more than 20,000 Hz. Such frequency level cannot be heard by a human. The sound which is emitted by ultrasonic repellers is aimed to cause a different kind of symptoms among pests, like convulsions, confusion and in some cases death. This process is known as an audiogenic seizure response. Under its influence mice will leave the area to find more friendy environment.
However, scientists report uncertainty if such products for pest control are helpful or not. The pest control professionals and scientific community are still debating about the ultrasonic mouse repellers efficiency.
