Yes it works

[This review was collected as part of a promotion.] Ok so I wasn't expecting much from this but after less than a day I can tell it does work. We've had some sugar ant issues in kitchen and tried this and it's definitely working. I like how it's safer for pets and we have children so I feel a lot better about using this brand

Safe and natural, works great

[This review was collected as part of a promotion.] This is now my go to product. Because it is safe and natural with no harmful chemicals. With having pets and children around, you are better off using this. I've tried it where I saw some ants and pretty much instantly. They were gone. Good to know that you have a product that is safe. Particularly these types of product. No powerful smell or anything in no residual left behind when using.

STEM Plant-Based Bug Spray is an excellent option

[This review was collected as part of a promotion.] STEM Plant-Based Bug Spray is an excellent option if you're seeking a gentle, effective, plant-based solution for quick bug elimination—perfect for families and pet owners. It delivers fast results on contact with minimal chemical odor. But, don't expect lasting protection—this product serves best as a spot-treatment rather than a long-term barrier. If you face recurring infestations, consider supplementing with baits or longer-lasting formulas.

10/10

[This review was collected as part of a promotion.] I've been using STEM to deal with ants, roaches, and flies in my home, and I'm honestly impressed. It works quickly and doesn't leave a harsh chemical smell like other bug sprays. I also love that it's made with plant-based active ingredients, which gives me peace of mind using it around kids and pets. Ants disappear almost instantly, and it's been great at keeping flies away too. A must-have for anyone looking for a more natural yet effective pest control option!

Safe for kids and pets!

[This review was collected as part of a promotion.] I absolutely love that this spray is safe for kids and pets!! I was happy that the smell wasn't too overpowering like some other sprays are. I feel like it worked great on the ants we had in our garage! I'm really pleased with this product and will be buying more Stem products again.

Effective and Safe Bug Spray

[This review was collected as part of a promotion.] The summer heat and humidity is here and so are the bugs. I've tried endless sprays, repellants and formulas to get rid of bugs, flies, roaches and other pesky things in my home but none have seemed to work that well. This spray was a big surprise to me. Very pleasant and light scent. A science-backed and proven formula. The use of botanical extracts and no other unnecessary, harsh chemicals. The best part, a safe and effective formula. I used primarily indoors around the doors and windows of my home and let sit for a few hours. I immediately saw a decline in the number of bugs entering or appearing out of nowhere in my home. I almost saw them disappear completely! Best of all, there was no awful scent or residue left behind. I love this stuff and would recommend.

Killed the bug

[This review was collected as part of a promotion.] A cockroach got into my husband's hydroponic gardening clay pellets. After a quick freak out, I realized this was the perfect chance to try my new bug spray since I hadn't had any ants come in lately. A quick spray and about 30 seconds, and it was over. The spray did leave behind a bit of what I assume is an oil ring. The garage smelled of botanicals for a day or so, almost citronella scented to me. I'm satisfied this product works. I like the shape of the bottle it fits in my storage area well. Not having a big bottom makes it feel like it's not wasting space. I feel like if I had used it inside I would have had to clean thoroughly right away but since it was a bucket of pellets we'll slosh them around with soapy water and I feel good that we can still use them in our garden.

Y'ALL… I just met my new hero in a spray bottle.

[This review was collected as part of a promotion.] Let me introduce you to STEM — the bug assassin that's rooted in nature but hits like science class with a vengeance. I sprayed this around my kitchen and bathroom and watched ants, roaches, and flies start packing their tiny suitcases. Not only did it kill them FAST (RIP), but here's the kicker: it's safe around people and pets. My dog sniffed the air like, “Is that lemongrass?” and went about his day. No choking chemical fumes. No hazmat suit needed. Just a clear, natural-smelling spray that means BUSINESS.

Great product!

[This review was collected as part of a promotion.] I received this product incentivized in exchange for doing a review on Influenster. I used this at my lake house for ants inside and outside of the house. Great product. Worked very well, but has a bit off a strong smell. I used it around the perimeter of the house and inside along baseboards. Saw results in a day or two. No more ants!
