## Customer Reviews

### ⭐⭐⭐⭐⭐ Best zap single shot spray
*by S***K on April 15, 2025*

Kills on contact. They drop and gone. No more flies or nats. I recommend this because I use this product at home. Perfect for flies and especially nats.

### ⭐⭐⭐⭐⭐ Bye-Bye, Bugs! 🌿
*by D***E on January 5, 2025*

So, I gave this Plant-Based Bug Spray a shot because, honestly, bugs are the worst, but I hate using sprays that smell like a chemical lab exploded. This one stood out because it's made with plant-based ingredients, which felt like a win for my home and the environment.🦟 The Good Stuff:It Works! I used it indoors and outdoors, and it actually kept flies, mosquitoes, and gnats away. It didn’t just knock them out—it kept them from coming back for a while.Smells Pretty Nice: No overpowering chemical stench here. The botanical scent is fresh and natural, kind of like walking through a garden.Pet-Friendly Ingredients: With two dogs running around, I feel better knowing I’m not spraying harsh chemicals near them.Versatile: Works great for random indoor fly invasions and keeping bugs off the porch during hangouts.🤷‍♀️ What Could Be Better:Short-Term Fix: While it’s great at getting rid of bugs on the spot, it’s not a long-term deterrent. You’ll probably need to reapply if you’re outside for a while.Spray Design: The bottle is functional, but the spray could have a finer mist for better coverage.🚪 How It Stacks Up:Compared to standard bug sprays, Stem is a great alternative if you’re looking for something plant-based and effective without the toxic vibes. It doesn’t have the crazy strength of DEET-heavy sprays, but for everyday use, it’s solid.If you’re like me and want to keep the bugs at bay without dousing your space in chemicals, this is definitely worth a try. Just keep it handy for re-sprays during longer outdoor hangs. 🌿✨

### ⭐⭐⭐⭐ Very oily but effective
*by L***E on March 31, 2025*

Very very very oily but very effective... you have to cover your floor and whatever else you don't want oil on this product will make hard floors very dangerous but my bug problem is finally solved
