Using the Bell Howell Ultrasonic Electromagnetic Pest Repeller Bell and Howell have been manufacturing lighting and electrical products for a very long time and this is why i do recommend one of their electronic pest control devices which has been tried and tested and again works very effectively to get rid of pest and rodents at the home.
This device will use the wiring of the house to create a pulse just the way the riddex product does and this pulse then produces an electromagnetic field which will make the pests uncomfortable so they will then move move away.
it should be noted that this device will not work perfectly in all weathers and especially in chilly weather the insects may tend not to feel the effect of the sound that is emitted by this device and that is why some people usually complain about this.
The problem is not usually the device but the timing of the weather.
It also produces a very beautiful green light that will ensure you do not light up you rooms where it has been plugged in.
This is very important because it saves you a lot of energy costs.
The cost is also very affordable and you can be able to get yourself one at around $15 - $20 depending on the store that you are purchasing.
You should also know that this device is not harmful at all to you and your pets because the waves produced cannot be heard by the normal human being
