Worth buying again

I received product reimbursement in exchange for my honest review. I love to start with that the bottle itself you don't have to worry about a child tampering with it & spilling the product out because it is definitely made to be child proof. The product itself has an acetone smell to it that lingers even hours after using it for those who may have breathing problems which makes me want to use it outside instead of inside. It is like you have to do multiple sprays for roaches, more than what it says in the instructions to be exact. It also works well for spiders even though it doesn't mention it on the bottle.

Pleasant scent, would use again

I received product reimbursement in exchange for my honest review. The sprayer and trigger on the bottle was great. It wasn't hard to squeeze and the spray was a nice mist. I have German cockroaches in my kitchen so I tried this product directly on a couple. The smell was botanical and pleasant. The roaches died but not instantly. It took some time for them to die off compared to other roach sprays. I would use it again since it did not have an ugly smell.

Careful where you spray

I received product reimbursement in exchange for my honest review. This stuff does work, and it's pretty fast. Do not let the spray hit any plants, it will damage them. The smell is pretty strong, but it doesn't smell too bad. The downside to this, you have to wipe the area where you sprayed, because it is an oil based spray.

Safe to use around my whole family!

[This review was collected as part of a promotion.] So summer just started and that means more bugs! Thank goodness STEM has a natural bug killer and repellent! I wanted to use something more natural when it came to killing bugs around the house. STEM is powered by plant-derived active ingredients! It smells like botanicals and can be used anywhere throughout the home. I used STEM ant, fly and roach spray and was surprised how easily the bugs died! No more flies in my home this summer. Best of all it's safe to use around my kids and pets!

Smell and leaves floors wet

Bought this product bc I needed something safe Inside for my dog. The smell is very very strong and I don't see it going away any time soon. Also upset that it does not dry. It just leaves a wet look where you spay it. I had to go back and mop it up and even then still smells. It killed the ants that I sprayed but the others walked around. Smell is too strong to do all along the walls to prevent the stragglers. I'm concerned now my pets walking on it bc it never dried.

Thank you for your review. Being made with essential oils, this spray does have a stronger fragrance. Usually, the smell dissipates within a few hours but it may take longer if sprayed heavily. Make sure to ventilate the area and wipe surfaces with warm, soapy water to get rid of the smell quicker. If we can be of further assistance, give us a call at 877-869-7546 (M-F 8 AM to 5 PM CT) and provide your reference number: 22093434. Have a great day! - Brooklyn, STEM Consumer Care

Works!

I received product reimbursement in exchange for my honest review. I tried this around my windows in my kitchen where I always see ants. It has been two days since I sprayed and there are no ants in site. I like that it is both pet and kid safe. The smell is light and pleasant as well

STEM spray

I received product reimbursement in exchange for my honest review. This is my first time purchasing this product. I like the spray bottle, it is better for the environment. I like that the bottle was clear, you could see what you're spraying. It was easy to use to directly hit the target area. It doesn't have a strong smell once sprayed which I love! Overall, I will purchase again and it works well.

Safe and Effective

I received product reimbursement in exchange for my honest review. Have anywhere from 3-6 pups running around the house, having an effective, pet safe, pest eliminating option is awesome! I live in a wooded area where throughout the year, ant invasions happen. In the middle of one of these episodes, I discovered STEM. I sprayed the area where the ants were thought to be coming in before going to bed one night. The next morning- not an ant in sight! The lemongrass oil adds a nice scent to the spray too. Peace of mind knowing its pet safe and it works- SCORE!

The stem product smells great and works great

I receive product reimbursement for my honest review this time product is awesome and I like the way it smells and I like to clarity that has in his bottle where you can see how much you have left without second-guessing not like aerosol cans we have to guess how much you have left and I'm glad that this is a product that is safe around pets and children and I've used it in the kitchen the bathroom and I've also used it outside in this product does say what it does it works fast and effective on contact and if this product can be childproof more with the trigger where they cannot operate it that would be great

Love this!

I received product reimbursement in exchange for my honest review. Prior to today I have never heard of the product STEM but do you plan on using it in the future. It works quick and effectively and I love that I don't have to worry about my kid or dog running around the area I've sprayed. Also the spray bottle feature is a huge plus for me. It's easy to use and target exactly where I need it to be.
