There are a several non-lethal mice control products that can help people dealing with rodents. Not all of these products work well and are effective, although they are regularly on the market. For the sake of completeness of information we list them.
Ultrasound devices emit ultrasonic waves above 20kHz, creating a loud noise for rodents equivalent up to 140 dB.
However, based on field test data, the commercial ultrasonic devices were not found to be effective for pest control application.
Several devices depend on emitting vibrations to frighten mice, but there are no scientific studies to prove their efficacy.
Very few mouse commercial repellants use some plant-based extracts – such as peppermint, spearmint, cinnamon, or essential oils- to get rid of mice.
While these are non-toxic, customer reviews claim that do not work at all, are inconsistent, and sometime even increase the number of mice.
Other commercial repellants use synthetic compounds to mimic a very strong, unpleasant garlic-like odor. In granules, or liquid, or powders, they must be reapplied weekly.
According to researchers, most of the time do not work at all.
Traditionally, essential oils such as lavender, citronella, geranium, or mint are known to have anti-parasitic properties, leading some people to use them as a mouse repellent.
Traditionally, essential oils are poured onto cotton balls or left in little open bottles near mice pathways.
However, essential oils are extremely volatile and they need to be replaced several times per week as they dissipate quickly.
Customers report that these traditional methods are not effective, and additionally, consume much more time and money to implement.
