More Information

How Ultrasound Waves Repel Rodents?

These Rodent repellents have a built in speaker that produces Ultrasonic Sound Waves with very high frequencies. These Frequencies are scientifically claimed to be intolerable by rodents. Hence, their first instinct is to leave the area in effect. These waves not only repels rodents but other pests and insects are also pushed out of the coverage area. While these frequencies are unbearable for these creatures, they pose no harm to humans and pets since they are way above our hearing range and the brain does not register them. Another problem is that these rodents are very resisting and adaptive creatures which can get used to a particular frequency. To counter this problem these repellents are design to have a random fluctuating pattern of various different frequencies which are very hard to adapt to.

How to Hook up these devices with Car Battery?

Half of the devices mentioned in our list are powered by the sharing a small supply from the car battery. It is quite easy to hook your rodent repellent with your battery terminals. After you open the car bonnet you will fit the device in a proper position next to the battery. Then take the end of your Red/Black Wire and fuse it with the positive pole of your battery and take the other Black/White wire and connect it to the negative pole. Make sure the connections are taught.

Now adjusting the device and tying it down in a fixed position is very important since most repellents are vibration sensitive and they need to be sturdy in their place to start functioning. Hence use some sort of velcro latch or the zip ties usually included in the package to tie the device down in one place. Now you can turn on your device so it can start defending your car from these pesky creatures.
