A worthy rebuff, or How to choose a rodent repeller

Probably, there is no need to explain once again what harm rodents can do to human health and property. It is better to talk about an effective and humane way to deal with them – ultrasonic repellents. More specifically, how to choose the best device for your situation.
An important indicator of any UZU is its capacity or the area that it is able to cover. These details are specified in the instructions. Most modern devices affect an area of 50 to 800 square meters. But keep in mind that any partitions and furniture can jam ultrasound, so if you are not going to install a repeller in an absolutely empty room, you should take a more powerful device. For large rooms, such as warehouses, devices with two radiators are recommended at once.
Pay attention to the frequency ranges generated by the device. It has been proven that rodents are able to get used to the frequency of ultrasound over time. That is why a high-quality repeller can periodically change frequencies. The more often this shift occurs, the less chance rodents have of living carelessly on your territory. But keep in mind that even a device with two different frequencies may be ineffective, since different rodents "hear" in different frequencies. Remember, the larger the frequency range of the UZU, and the more frequently the frequency estimates occur, the better.
Ideally, the frequency change should take place automatically thanks to a special switch. Yes, of course, there are devices with mechanical switches, but then you literally have to run for hours to the ultrasound in order to "change the record."
Now, a few words about the design of the repellents. Pay attention to the radiator. If it is open, the device will work as efficiently as possible. The radiators hidden in the case, alas, cannot boast of high efficiency. This is elementary physics.
It is good if the UZU is equipped not only with a socket, but also with a cord, as well as a holder with which the repeller can be directed in any desired direction or hung from the ceiling.
A high–quality repeller is a great way to get rid of rodents. But keep in mind that a miracle will not happen in one day. It will take several weeks for the pests to go away. In general, to achieve maximum effect and prevention, any ultrasound should work for two months. Then the repeller can be turned off for a while.
