Review: Works great - I had ants coming from my ceiling area this year??? I tried everything, but, being in my kitchen everything dripped..yuck!!!! I got this because it was safer for my pets..has a nice even spay, and doesn't drip, like raid..the smell isn't great, but, didnt last too long..it did make the surfaces slippery..which I dont mind for a couple days, because its keeping the ants away. Im giving 5 stars because it worked great, price is good, smell is doable, well considering my other options, or ants in my food..
Review: Actually smells nice - Smells like a heavily perfumed air freshener and not at all like a bug spray, at least none I've ever used. I bought my first can in the summer of 2024, my second a year later, and here I am with a third can in 2026. It dispenses easily and evenly and works quickly both indoors along the baseboards indoors and on ant hills and swarms outdoors. The smell can be a little overwhelming indoors so I make sure to air out the rooms where I use it. Even though it's marked as being made from natural ingredients that are pet safe, I isolate my cat away from the area of application for at least an hour, just in case.

### ⭐⭐⭐⭐ All natural
*by M***N on June 16, 2026*

Fantastic for killing roaches. I hope it works on the ants as well. Have never seen roaches in my current apartment before I had a new neighbor that's a hoarder. Now I've got some showing up. I have cats so I needed a safe spray. The scent is super strong. Best to be careful using it
