It works

[This review was collected as part of a promotion.] I'm not a fan of the scent, it really bothers my nose. However, I started noticing water bugs and even a few roaches, which I hadn't seen in over 15 years. Ever since some new neighbors moved in, the roach problem started, it's like the bugs came with them. While some neighbors with insect phobias completely freak out (which I find a bit amusing), I decided to try this product because it's natural. Although I really dislike the smell it leaves behind, it actually works very well. Just a heads-up: it's not a quick-drying spray. I use it under my sink cabinets, and it leaves a greasy residue, so I have to clean it up after a few days. Still, I'd rather deal with that than have pests running around. If you spray it directly on a roach or water bug, it kills them instantly. It's effective!

Def recommend

[This review was collected as part of a promotion.] I got to try this when I started having ants coming out of nowhere in my room and living room. Used it for a few days and I haven't seen any since so I think it also kills and keeps them away. I just don't like that you have wipe down after it because of the residue, didn't notice that on first try and almost slipped in it.

Pet-friendly STEM spray works on ants!

[This review was collected as part of a promotion.] I tried this STEM brand ant, roach and fly spray on my paver patio to get rid of the ants. I just checked it 7 hours later and no ants. It's a great value and I love that it can be used around kids and pets. I liked it so much I bought the STEM spray for flies, mosquitoes snd gnats.

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.

Effective, natural, safe.

[This review was collected as part of a promotion.] This spray kills ants, roaches, and flies fast, which I love. It does have a pretty strong smell and leaves a slight oily residue, so I usually wipe surfaces after. But since it's plant based and safe around my pets and kids, I feel good using it inside and outside.

A more natural bug spray that is safe and effectiv

[This review was collected as part of a promotion.] I was happy to see a product that is kid and pet safe. Although I do not have little ones in the house, it makes me feel safer using it around my husband and I as well as our pets. We have pest control service, but I haven't had them spray inside the house due to concern for the safety of the chemicals. The exterior treatment does a really good job but doesn't prevent every bug. I also tend to have issues with bugs getting in the garage. I was able to use this spray, which doesn't kill on contact, but the bugs die within 30 seconds or less. I like the fact that this doesn't have the strong chemical smell that a lot of products have.

Kills bugs instantly.

[This review was collected as part of a promotion.] Stem bug spray kill bugs instantly. I used in my kitchen area and bathroom to rid of bugs. Within seconds the bugs were no longer a problem. The scent of the spray isn't too harsh. It was noticeable when a lot is sprayed. Also it was very oily like on tile. This was an issue for me as I almost slipped. Must clean the area after each use for safety issues. Overall a great spray and with the purchase.

Friendly flies killer

[This review was collected as part of a promotion.] This STEM insect spray is a smart and safe solution for getting rid of flies, ants, and roaches. Made with plant-based active ingredients like geraniol and lemongrass oil, it's safe to use around people and pets when used as directed. The scent is mild and not overpowering, making it a great alternative to harsh chemical sprays. Plus, it's affordable and easy to use—perfect for everyday pest control without compromise.
