Works Amazing!

[This review was collected as part of a promotion.] The packaging is great! I can smell lemongrass. It works very well! I'm so amazed at how quickly it works. I've been having flies and ants problem. I tried it with both, and they killed them instantly! It's safe for people and pets. It's worth the money! I'm so glad I finally tried it cause it works and it's not harmful!

Safe to use around family and animals

[This review was collected as part of a promotion.] Safe to use around animals(such as pets, dogs, cats, ect…) and family. Not a super strong smell but it does smell like bug spray unfortunately. Can use outside or in your house. Good sturdy bottle and sprayer. Work great for those pesky fruit flys aka nats.

Very effective!

[This review was collected as part of a promotion.] This has worked very well. It doesn't say it's for wasps, but I sprayed around the deck outside and haven't seen a wasp since. The scent isn't the best but it's not terrible, just strong. Very good value!

If you don't like geranium type smells you won't l

[This review was collected as part of a promotion.] The product works, but I hate the smell. (A different brand uses minty smells and I love it and it works faster) this one is effective but doesn't seem to work as fast. So to me it is much less effective The sprayer works well giving a nice mist and I love that is safe around pets but I can't stand the geranium like scent .

Highly Effective and Safe Bug Spray for Home and O

[This review was collected as part of a promotion.] I am extremely impressed with the STEM Indoor & Outdoor Bug Spray! It's easy to use, has a pleasant scent compared to other bug sprays, and the most importantly— it really works. I've used it both inside the house and outside my patio, and it effective kept mosquitoes, ants, and other pets away without leaving any sticky residue or harsh chemical smells. I also appreciate that it's made with plant-based active ingredients, making me safer using it around my family and my pets. Highly recommend for anyone looking for reliable and safe pest control.

Top Competitor

[This review was collected as part of a promotion.] I prefer this to my other and spray because it is safer for my household and still effective. We have ants in our kitchen frequently and this spray is just as good of a job as our other name brand spray but the fact that it is made from safer ingredients makes me want to use this one from now on.

Effective Bug Spray

[This review was collected as part of a promotion.] The Stem sprays is easy to spray and so effective. It has strong smell and lingers but it's not unpleasant one and it's also plant based so no more bad chemicals . The size of the bottle is perfect as compared to money . It's money value packaging . It's so easy to store and easy to use . I love small indoor plants and it's helps to keep the bugs away . It's safe to use while kids being around . So I can recommend it .

Keeps insects away

[This review was collected as part of a promotion.] This stuff really works. We've had ants and stink bugs invading our house for several weeks now. The scent of this seems to keep them away in addition to killing them on contact. The package is easy to use and spray in the right places. Overall, it's a good value for the money. Much cheaper than an exterminator.

Love

[This review was collected as part of a promotion.] I was looking for a safer alternative to traditional chemical bug sprays, and the STEM Indoor & Outdoor Bug Spray really impressed me. It's plant-based, but don't let that fool you—it works! I've used it on ants and flies around the kitchen, and even outside near the patio, and it starts working almost immediately. I love that there's no harsh chemical smell, it actually has a light, herbal scent that's not overpowering. Plus, I feel better using it around kids and pets. The 12oz size is easy to handle and lasts a decent amount of time. Definitely a new staple in my home! Great value for the price.
