I was quite skeptical at first, but after using this Pest Offense plug-in repellent for over a month, I must say it has made a noticeable difference. We live in an apartment and were seeing small roaches and ants in the kitchen, especially at night. After plugging this in, the activity has reduced drastically — it’s almost gone!What I really appreciate is that there’s no smell, no sprays, no mess. Just plug and forget. There is a small green light which shows it’s working. Very easy to use.As someone who grew up in India where pest problems are common, I’ve seen all kinds of sprays, chalks, and traps — this is much cleaner and safer, especially with my baby nephew visiting home often. No need to worry about him touching anything harmful.It may take a few days to start showing effect, so give it some time. But once it kicks in, it really helps. I’m planning to get one more for the guest room.Highly recommended if you’re looking for a chemical-free solution!
