Review on 6 Pack Ultrasonic Plug-in Pest Repellent for Indoor Mosquito, Rodent, Mouse, Cockroach, Rat, Ant, Spider, Flea, Fly Control by Holly Naragon

I had really high hopes for these things, but wherever I put them, instead of scaring away spiders, they attracted them because they set up their correct networks. on them. I know it means waiting a while until you see more bugs before it gets better, but I've had them for about 6 weeks and it hasn't gotten better. It's actually worse.
