Electro-magnetic repellers started appearing on the market just a short while ago. There are several brands that offer claims that their product changes the house wiring into a magnetic field that chases rodents and insects away. We have not seen any research that backs up these claims. Further, there is no evidence that electromagnetic energy does not have an affect on children, adults, or pets in some manner. Sorry, but until they are proven 100% safe, we will not be offering that technology to our customers.
