Safe to use inside

[This review was collected as part of a promotion.] Bug spray made simple! Safe and effective way to slay away at the unwanted pests that make their way into our homes. Because of the simple ingredients in the spray, it's harmless to people and pets, so safe to use inside. Rooted in nature, optimized by scientists. No harsh chemical smell.

Works Instantly

[This review was collected as part of a promotion.] The STEM Kills Ants, Roaches,and Flies product works quickly to eliminate bugs. I tried in the kitchen, where I had several gnats, and it instantly killed them. Afterward, I quickly wiped down the wall surface. I'm pleased with how well it works. One aspect I appreciate that there is no chemical odor. I also like that STEM is made from botanical extracts, making it safe to use indoors around my grandkids and cats. However, I prefer to use it outside because I do not like the lemongrass scent . It's a great product, and since the scent doesn't bother my husband, I'll have him use it inside when I am away for the weekend.

Great value for the price

[This review was collected as part of a promotion.] This is a large amount of product for the price. I used it in our home were I saw some ants, and now I don't see them anymore. Pretty straight forward packaging, it works well has the turn dial for “off” and “on” to make it safer. To me the scent has a vinegar with something else scent. It's not crazy offensive but you can smell it if you spray it in your home.

It's good

[This review was collected as part of a promotion.] It's a soft approach to traditional insect spray. It does have a smell that i am not crazy about, but i like the fact that is safer for plants and around the house overall. I like the bottle spray, better than the other spray. The price is reasonable for the amount.

Effective, but strong smell

[This review was collected as part of a promotion.] The product seems very effective at repelling ants and other bugs from areas where you spray it. I like that there's a clear on and off toggle for the spray. Two things to note - there is a slight smell, and if using this spray on carpet it may leave a stain over time (as seen in the picture).

It's oily but it works!

[This review was collected as part of a promotion.] First and foremost, I hate the scent of big spray. I find it rather noxious. But I live in area where ants, fire ants, and stinging bugs are plentiful so I have to keep a can nearby on my porch. If I want to enjoy outside at my house...I have to get rid of a big or two. I like this because it's in a spray bottle and I can lock the bottle from spraying. I can safely grip the handle and aim it. I don't have to shake up the contents to get a spray that actually reaches the bugs. The scent is not overpowering at all. It's still a big spray and it will smell like it but not so strong that it takes my breath away. My only qualm is the spray is oily. So I can't spray directly on my wood deck without leaving stain that I have to scrub out later. I will purchase with my own money after I run out.

Safely say bye to bugs!

[This review was collected as part of a promotion.] Okay, let's talk about this STEM bug killer. Seriously, if you're like me and hate those super harsh chemical sprays, this stuff is a breath of fresh air – literally! First off, the safety aspect is a huge win. The bottle practically shouts "SAFE AROUND PEOPLE + PETS," which immediately puts my mind at ease, especially with two dogs and two cats wandering around the house. The smell is absolutely wild. Instead of that typical chemical stench, it legitimately smells like a nice bowl of cereal! I'm not kidding. It's so unexpected and actually makes spraying for bugs... almost pleasant? But don't let the nice smell fool you, this stuff is surprisingly effective. It says it "KILLS ANTS, ROACHES, FLIES," and yeah, it totally does. I've even had some success with other little creepy crawlies that aren't listed, though I'd probably stick to the bugs it's actually designed for to be on the safe side. The packaging is pretty simple, small, and clean – a clear spray bottle that's easy to hold and looks pretty decent sitting out, not like a hazardous waste container. And honestly, the best part? It's surprisingly cheap! You're getting something effective, safe, and that smells good, all without emptying your wallet. Definitely a smart buy in my book.

Worked on mosquitos!

[This review was collected as part of a promotion.] I used this product to test on the mosquitos because we have a lotttt of them in the area I live in. I would say it worked as well as bug spray in a can would work. Worked for the most part but there were a few that bothered me. I think the smell is what really helped. Smells like a strong citrus smell, pleasant I would say. I also liked this product because it's safe around pets which I have.
