The best!

[This review was collected as part of a promotion.] This is a fantastic bug spray! It's extremely effective; ants and roaches worst enemy, flies too. It has a strong herbal scent, which is not unpleasant. You only need to use a little at a time so the bottle definitely lasts. It's also super easy to use, just spray and you're done. I also love that it's safe to use around people and pets!

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.

Works great indoors and out.

[This review was collected as part of a promotion.] Really liked this spray. I was able to use it inside and out. We were having bugs accumulating around the gate of our fence outside. I gave it a few sprays and it worked well. The bugs seemed to stay away. I just reapply every few weeks and it works great!

Works Great!

[This review was collected as part of a promotion.] I received this product from Influenster and Stem for free in exchange for my honest review and opinion of the product. I've used this outside my front and back door and I must say I'm impressed. It work fast and efficiently. Within 3 days all the bugs around my doors were gone and haven't come back

Effective!

[This review was collected as part of a promotion.] This was very effective, we actually sprayed the screen door going into our garage and it worked quite well. I would say our only complaint is that it is rather oily. We sprayed a little haphazardly and it made our kitchen floor slippery. So we will be more careful when using next time. It has almost light citrus scent so it was rather pleasant for a bug spray! I would recommend this product.

Problem solved

[This review was collected as part of a promotion.] Stem for ants, roaches and flies works great. We were having an issue with ants around the dog food and it has done such a great job of keeping them away. It was easy to find at my local stores and a great value. It works great for both inside and outside of the house. It does leave a mark when sprayed on certain surfaces (looks like oil sprayed) but works great and the mark eventually goes away.

Not a bad chemical smell

[This review was collected as part of a promotion.] I used this product to kill a roach in my house. Unfortunately it did leave a stain on my rug that I am hoping will come out when I shampoo the rug. It did however kill the roach within 10 seconds which was nice. It does not have a foul bug chemical smell. It is pleasant. Test on small surface first before using on large area.

Safe for Pets

[This review was collected as part of a promotion.] I don't use insect sprays often because I have a dog and worry about how it could affect him in the long run. This one specifically says that it's safe for pets, which gave me peace of mind. Lately I've had issues with ants! They're all over my potted plants. Tried this out, and it was very effective around my plants. I didn't spray directly though because I wasn't sure if it was plant safe as well. Pretty scent less as well.

Affordable bug spray

[This review was collected as part of a promotion.] Its a pretty effective bug spray as i used it around spraying the areas i normally get ants or flies and I've less of them. The spray however stays sort of like an acid or oil for a long time after so be warned. Not strong smelling and fairly easy to use.
