The Riddex's ultrasonic insect repellent device doesn't actually work as tested in the video there are also multiple other videos online and even articles about class action lawsuits against companies that have created similar products. So far my best results with insect and spider control have been with traditional insecticides and not electronic devices. This seems to be the case with others who have also tested these devices.
