People might be messing with the app tbh I notice after a bit lights will show and then the bugs will reappear following them, is there a way to make it more efficient? ### 5/5 — Dat funkiotinert!!!! *2023-07-10, version 1.615* Also ehrlich!

If u don’t buy this right now u r not gonna b alive for 6 mostly worst plagues they bring, remember u pied piper first and most important thing they taught u!!!!!! ### 5/5 — I was skeptical *2021-04-09* I was staying in an AirBnb and mice were in the wall and floor the first three nights of my stay. They kept getting more active each night. I didn’t realize there was an app for that. I got the app and put my phone on the floor. The first night it sounded like they came and went. The next night, nothing. So, I wasn’t using it long term, and I don’t usually write reviews, but I was really impressed that it actually worked great for my purposes. I let the owner know about it when I left, but I didn’t want her calling in the exterminators during our stay, which would have been a hassle. ### 5/5 — Bugs just seem to disappear! *2021-02-20, version 1.615* This app is great for making the environment so unpleasant for bugs. Either they leave or endure misery to stay! ### 5/5 — Mr Neil *2020-09-19* Within 20 minutes the rats moved out of the roof. ### 5/5 — Its Work *2020-05-16, version 1.614* I Have tested to reppel rat in my house. ### 5/5 — Pest repel is great! *2020-03-29* I love Pest Repel! We have a lot of mice in our house and the app is very useful to get rid of them! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
