Works well!

[This review was collected as part of a promotion.] Works well, only issues I found is that it is a bug killing spray, not a preventative spray like I originally thought. Many ants and Nats move around too much to be spraying on the go. Otherwise works well and smells good.

Effective and safe bug spray for indoors and out

[This review was collected as part of a promotion.] This product worked well and quickly in my kitchen for killing some ants. The scent wasn't awful and not strong unlike some other bug sprays I have tried. It was nice to know that it was plant based which made me comfortable to use with kids around. It is a little pricey but I think it's worth it.

Good product.

[This review was collected as part of a promotion.] This is a pretty good product. I have never used stem products before so using these products for the first time was definitely something new. This product in particular I used for ants and it worked almost immediately. I like the fact that there was really no scent to the product, also that it is safe to be used around children. I would definitely recommend this product.

Bugs be gone 10/10 🙌🏽

[This review was collected as part of a promotion.] This spray is amazing! With summer little ants are constantly popping up and one spritz of this stops them in their tracks! It also has a nice smell to it, and a little goes a long way! I even spritzed it on a wasp that had gotten in my house and it dropped from mid air! Totally worth it in my opinion for someone like me who hates bugs! Super effective and worth every penny!

[This review was collected as part of a promotion.] I love scent it's very strong and lasting though lol but it's effective too we have beetles that sit at the door spread all of them and they dropped real quick I don't like the mist of it so be careful where you spray 🤣

It's oily but it works!

[This review was collected as part of a promotion.] First and foremost, I hate the scent of big spray. I find it rather noxious. But I live in area where ants, fire ants, and stinging bugs are plentiful so I have to keep a can nearby on my porch. If I want to enjoy outside at my house...I have to get rid of a big or two. I like this because it's in a spray bottle and I can lock the bottle from spraying. I can safely grip the handle and aim it. I don't have to shake up the contents to get a spray that actually reaches the bugs. The scent is not overpowering at all. It's still a big spray and it will smell like it but not so strong that it takes my breath away. My only qualm is the spray is oily. So I can't spray directly on my wood deck without leaving stain that I have to scrub out later. I will purchase with my own money after I run out.

Definitely a better option

[This review was collected as part of a promotion.] This has been working good for our random flies that keep showing up in my house and back porch. It's plant-based, which I like, and it didn't leave that harsh chemical smell hanging around. I sprayed near entry points and all over my back porch and it kept bugs from wandering in for a while. I wouldn't say it's a total miracle worker, but for something more natural, it held up better than I expected. A decent option if you're trying to keep things low-toxic but still effective.

Great Natural Bug Spray!

[This review was collected as part of a promotion.] I've used this STEM spray both indoors and on my patio, and it really works! It kills ants and flies quickly without the harsh chemical smell. I like that it's plant-based and safe to use around my family. The scent is a bit strong at first, but it fades quickly. Would definitely buy again!

Stem Bug Spray! Try it!

[This review was collected as part of a promotion.] I've been using the STEM bug spray, and I'm honestly really impressed. It works well on ants and roaches around the house, and I love that it's safe to use around kids and pets. That peace of mind means a lot to me. The spray bottle is easy to handle and gives a good, even mist without any weird chemical smell—it actually has a more natural, plant-based scent, which I really appreciate. I've used it both indoors and on the patio, and it's effective without leaving behind any sticky residue. For the price, it's totally worth it, and I like that it's powered by science but rooted in nature. I'd definitely buy it again.

Checks all of the boxes

[This review was collected as part of a promotion.] We've been using this for an about a month now and I love it. Consider it spot treatment for outdoor pests. My husband and I love spending time on our front porch and this spray has been such a lifesaver for us. Since we have 3 dogs that like to lounge with us being pet friendly is a must and this one checks all of the boxes
