This stem natural insect killer doesn't work very well as well as the spray can itself stop spraying after about half the can is missing. It's a waste of money.

Worth every penny. Works great.
This works so well. It’s basically immediate. You don’t have to keep spraying. It has a strong odor that isn’t pleasant, but I don’t think it’s a deal breaker. This is safe enough to use with a pet nearby. I’ve bought this repeatedly due to the consistently impressive performance of this formula on a variety of bugs.

Unexpectedly effective
I had doubts but it's effective right with the first spray and I don't mind the smell at all as it reminds me of rosemary and I also didn't have to wait until the aerosol to disperse for a while to return to my room. One thing I don't quite like is that it's sugary sticky so I have to wipe down the surfaces but I suppose that's the mechanism of the spray to be effective. It's quite small but for living in a small space I will definitely buy it again.

Strong scent
[This review was collected as part of a promotion.] I like that this is a natural product and it does seem to work. It only works on contact with bugs. Besides that, I think the product smells very very strong. It smells like essential oils but it is very strong. It is super oily and I had to wipe it off after I sprayed it. It is hard to hit a bug with the spray unless it’s ants or something slow. I didn’t trust spraying it many places since it is oily I assume it will stain. This is not my favorite product. I’ll stick to the flyswatter inside and maybe use this outdoors but even that makes me nervous because I’m not sure if it’ll stain certain surfaces.

We're sorry to hear you were disappointed with STEM, and we appreciate you sharing your feedback. Since the spray is made with essential oils, it does have a stronger scent, but it usually fades within a few hours. If the area was sprayed heavily, the fragrance might linger a bit longer. To help the scent clear out more quickly, we recommend ventilating the space and wiping down surfaces with warm, soapy water. If there's anything else we can do, please don’t hesitate to reach out at 877-869-7546 (weekdays, 8 a.m. – 5 p.m. CT), and have your reference number handy: 22969091. We’d love to help get your space back to bug-free!

Great product to help prevent critters
[This review was collected as part of a promotion.] Very easy to use. Bottle has worked very well for the exterior of my home. Not letting flies roaches or ants. Get in safe for animals and people has a pepper mini smell but that is for helping keep the critters away. Overall a great product.

[This review was collected as part of a promotion.] I didn’t find this item very effective as I still got many bugs indoors. Many many flies around my house so the spray may not be the issue of the product but unsure.

Instant Bug Killer
On a monthly basis, I purchase Stem Ant-Roach-Fly-Insect Killer Bug Spray to deal with the fruit fries in the kitchen, from spring to fall. With a spritz here and there, it does the job perfectly. I love how it's safe for people and pets, and made from natural ingredients like essential oils. It's also on my list to buy all the time.

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.

Safer option
[This review was collected as part of a promotion.] Seems to work well. I like the fact that it’s a safer choice than other ant and roach sprays out there. Safety is a big factor for my household. The only issue really can be the residue it leaves.

Scadimg hot water works faster
[This review was collected as part of a promotion.] I received this product for free in return for my honest review of the product. I really didn't care for this product at all nor will I be purchasing it again. The scent was pungent and it hung around for hours afterwards. I had tried to use this product to kill ants that were around the outside of my home and it didn't kill them unless I really drowned them with it. I could have killed them faster with scalding hot water.

STEM Bug spray works effectively !
[This review was collected as part of a promotion.] I tried the STEM Indoor and Outdoor Bug Spray and was impressed with how well it worked. It killed ants and flies on contact, and I felt comfortable using it since it’s plant-based and safe around kids and pets. I also really liked the light lemongrass scent it’s much better than the strong chemical smell of other sprays. The only small downside is that I needed to reapply it a couple of times, and it can leave a slight residue. Overall, I think it’s a great eco-friendly option that I’ll keep using.
