The Riddex pest repeller produces high-frequency sound waves that are harmless to humans and pets (except rodents), but which are heard by insects and rodents and are supposed to drive them away. This may sound good in theory, but it doesn't work in practice. At best, electronic pest repellers may work for a few hours or days, but they apparently have no long-term effect on pests. Also, many people claim that they can hear a whining and/or buzzing noise made by the repellers. After numerous complaints, the company that produces Riddex agreed with the FTC to not make certain claims as to their product's effectiveness.
