When we first plugged it in once we received, we saw that the spiders were still around and that the device wasnt working. Now that the repellent has been plugged in for within 2 weeks i've seen no mice or spiders. I realised that on the product description that it states that the pest may increase at the beginning while the ultrasonic waves start to kick in. Since I plugged these in I've seen none! Absolutely none, I can't believe it. I am very happy with this product which has prevented bugs from invading my home. I have small children so the bonus is, it is chemical free, just plug in and it goes to work! I highly recommend.They really work! I would definitely buy more but just give it a few weeks to see the difference. Great repellent!!
