Worked on mosquitos!

[This review was collected as part of a promotion.] I used this product to test on the mosquitos because we have a lotttt of them in the area I live in. I would say it worked as well as bug spray in a can would work. Worked for the most part but there were a few that bothered me. I think the smell is what really helped. Smells like a strong citrus smell, pleasant I would say. I also liked this product because it's safe around pets which I have.

STEM Bug spray works effectively !

[This review was collected as part of a promotion.] I tried the STEM Indoor and Outdoor Bug Spray and was impressed with how well it worked. It killed ants and flies on contact, and I felt comfortable using it since it's plant-based and safe around kids and pets. I also really liked the light lemongrass scent it's much better than the strong chemical smell of other sprays. The only small downside is that I needed to reapply it a couple of times, and it can leave a slight residue. Overall, I think it's a great eco-friendly option that I'll keep using.

Highly recommend for anyone looking for a safer, e

[This review was collected as part of a promotion.] I'm really impressed with this STEM bug spray! It feels much safer to use around my kids and pets since it's plant-based and contains no harsh chemicals. The lemongrass scent is fresh and clean, not overpowering like traditional sprays. The packaging is simple and easy to use, and the spray nozzle gives excellent control for targeting bugs. It kills ants and flies almost instantly and even works on roaches with a direct spray. It's not a long-term repellent, but for spot treatments, it's super effective. For the price, it's a great value, especially considering it's safer and smells way better than chemical alternatives. I'll definitely keep a bottle on hand, both indoors and out!

Works well!

[This review was collected as part of a promotion.] I love this plant based bug spray, it does not have an over powering scent and kills bugs! Since we have plants around our home gnats can become an issues especially when adding new plants to our home. Easy to use and spray.

Bug spray without the harm.

[This review was collected as part of a promotion.] With summertime in full blast, it's almost a must to have bug spray handy anywhere you go. While some are very harsh and unsafe, STEM offers efficiency and less harsh chemicals. It smells like lemon and works so very well. Our tiny ant friends can be persistent and this spray keeps them away. Highly recommend!

Safely say bye to bugs!

[This review was collected as part of a promotion.] Okay, let's talk about this STEM bug killer. Seriously, if you're like me and hate those super harsh chemical sprays, this stuff is a breath of fresh air – literally! First off, the safety aspect is a huge win. The bottle practically shouts "SAFE AROUND PEOPLE + PETS," which immediately puts my mind at ease, especially with two dogs and two cats wandering around the house. The smell is absolutely wild. Instead of that typical chemical stench, it legitimately smells like a nice bowl of cereal! I'm not kidding. It's so unexpected and actually makes spraying for bugs... almost pleasant? But don't let the nice smell fool you, this stuff is surprisingly effective. It says it "KILLS ANTS, ROACHES, FLIES," and yeah, it totally does. I've even had some success with other little creepy crawlies that aren't listed, though I'd probably stick to the bugs it's actually designed for to be on the safe side. The packaging is pretty simple, small, and clean – a clear spray bottle that's easy to hold and looks pretty decent sitting out, not like a hazardous waste container. And honestly, the best part? It's surprisingly cheap! You're getting something effective, safe, and that smells good, all without emptying your wallet. Definitely a smart buy in my book.

Not the best scent but def does the job

[This review was collected as part of a promotion.] The scent is not the most pleasant in the world, smells like chemicals BUT it gets the job done. We had an infestation of ants this summer and the traps weren't enough. We sprayed them with this and they died within minutes. Definitely had to wipe away reside on surfaces.

Amazing and effective

[This review was collected as part of a promotion.] I was looking for a bug spray that's both safe and effective—and STEM really delivered! I love that it's made with plant-based ingredients and doesn't have that harsh chemical smell like most sprays. I've used it both indoors and on the patio, and it works great against ants, flies, and even roaches. It's a big plus that it's safe to use around pets and kids (when used as directed). The scent is very mild and natural, and I appreciate that there are no added dyes or fragrances. Highly recommend if you want a cleaner, greener way to protect your home from bugs!

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!

Works great, super strong smell

[This review was collected as part of a promotion.] I was excited to try this Stem bug spray. We have been having a lot of springtails this season. I sprayed our porch outdoor sills and it worked on contact. The issue I had was how strong the lemon oil smell was. I couldn't imagine using it inside.
