Pest Reject is an ultrasound and electromagnetic pest repellent that has appeared in Croatia a few years ago. God only knows who designed it and where it is produced. Plugged into an electric outlet, it is supposed to drive away all sorts of insects, rodents, and many other pests from the house. I got one of these gizmos about a year ago. It has been plugged into an electric outlet in my house ever since. So, what is my experience to date? It is hard to tell. Many pests seem to be gone by now, but some are still around. How do I know? I find long-legged spiders and their webs all around the house. The pest repellent seems to be powerless in their case. But they do not subsist on air. The insects they go for must be all around the house, as well. Indeed, wherever there are spiders, there are remnants of their prey. In short, Pest Reject is not working all that well. And I can prove it by pointing at so many spiders and their webs around my house. But why do I go on and on about this product? It has a wonderful name. Beware of wonderful names, that is.
