I will share my experience with those ultrasonic devices,
For big roaches , is totally effective, they run from the area almost the same day,
For small roaches, they began to crawling walls even at day time randomly, like they are going out of their nest, so you can kill by yourself, in my case was helpful but not a final solution , maybe need more than a weak for more results, but the blue light terrorize them, when they cross by they run scare ,
