Works quite well against ants

[This review was collected as part of a promotion.] I was excited about this campaign because I discovered red ants in my flower garden. I needed something that was safe and natural because of our pets & local wildlife. Perfect timing for this opportunity! The bottle is easy to hold and spray, I like that it's natural, and it did make the ants pack up and leave. Im very happy about that. However, this product claims to be plant safe, but it caused some of my wild violets to die. I am bummed about that. Overall, I like this product because of its effectiveness against the ants & safety for pets. Not so happy about it killing some of my flowers.

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 and does the job

[This review was collected as part of a promotion.] I used this product outside of my home in my garden beds where I've been having a lot of ants. The ants have not yet came into my house. I sprayed my garden and the answer significantly lessened. The smell of this product is not overwhelming. It smells almost like citronella. It has lemongrass as one of the main ingredients. I love that it's not a deterrington and actually kills the ants.

Safer Alternative

[This review was collected as part of a promotion.] This is a good option for indoor use. I have pets and felt this was a better alternative than more toxic products. I used this around my kitchen trash can to repell the flies that summertime can bring.

Works great

[This review was collected as part of a promotion.] I found a trail of ants running into my yard and it's been there for the last month. I used this spray and it instantly killed the ants. There isn't a nasty, chemical smell to the product. When I sprayed it, it smelled like lemongrass! The instructions tell you not to use it directly on plants. I think I might have gotten it on my plant so we'll see if there's any harm to it but so far so good.

Safe and effective

[This review was collected as part of a promotion.] I've been using the STEM spray for a while now, and it really works! It quickly takes care of ants, roaches, and flies just as promised. I love that it's plant-based and safe to use around people and pets — that gives me peace of mind, especially with kids and animals in the house. The scent is mild and not overwhelming like chemical sprays. Highly recommend for anyone looking for a natural alternative to traditional bug killers!

Nice scent

[This review was collected as part of a promotion.] It's time of the year when ant start coming back. I used this spray and didn't see any trace next days . The smell is not too strong and I have dogs and kids . So it will be a plus if the product safe for them.

Love natural home solutions!

[This review was collected as part of a promotion.] First of all I am a fan of this being plant based. I try to be conscious of spraying things around the house that are people and pet friendly. But sometimes the “natural” solutions just don't work. This one is different! I sprayed it right on ants in my kitchen and it killed them within seconds. It has a natural smell that's a little strong but not chemically. This is great for spring/summertime when ants are everywhere!

Kills ants and safe for my dog!

[This review was collected as part of a promotion.] Every spring we get ants on our window sills…today my daughter said the ants are back I said perfect I just got some new spray to try!!! We sprayed the window and the ants died on contact!! I love that it's safe for my pet to be around as he does go in her room!! I will say that it has a pretty strong unpleasant smell that lingers a little longer than I expected…but it is a bug spray…
