My mom house has a roach and rat problem, I was wondering if the product Riddex really work?

and also head to toe mousetraps, is there a trick o this or is there any other way other than baits to kill theM

i saw a product called riddex on tv

I am looking for something that will plug into a wall and emit a frequency that the pesky squirrels in my attic will hate. Has anyone used any of these products, if so, how would you rate them?
