Review on 🐜 2021 Ultrasonic Pest Repeller (6 Pack) - Electronic Bug Repellent for Ants, Mosquitoes, Mice, Spiders, Roaches, Rats, Fleas, Flies by Sarah Greenwood

I have to write this very positive review for all of you like me: repulsive and scary mice (whether harmless to humans). I bought these repellents in June and was very lucky. So far only a small bag has entered the house. On the advice of an animal expert, we have used Tomcat bait boxes for years and replace them every month/6 weeks. They're doing their job well, but the mice got in anyway. We have replaced very little since July as there are still plenty of baits left in most boxes suggesting the ultrasonic repellent is doing its job. Hope Revain restocks soon!
