Bye-Bye, Bugs! 🌿
So, I gave this Plant-Based Bug Spray a shot because, honestly, bugs are the worst, but I hate using sprays that smell like a chemical lab exploded. This one stood out because it's made with plant-based ingredients, which felt like a win for my home and the environment. 🦟 The Good Stuff: It Works! I used it indoors and outdoors, and it actually kept flies, mosquitoes, and gnats away. It didn’t just knock them out—it kept them from coming back for a while. Smells Pretty Nice: No overpowering chemical stench here. The botanical scent is fresh and natural, kind of like walking through a garden. Pet-Friendly Ingredients: With two dogs running around, I feel better knowing I’m not spraying harsh chemicals near them. Versatile: Works great for random indoor fly invasions and keeping bugs off the porch during hangouts. 🤷♀️ What Could Be Better: Short-Term Fix: While it’s great at getting rid of bugs on the spot, it’s not a long-term deterrent. You’ll probably need to reapply if you’re outside for a while. Spray Design: The bottle is functional, but the spray could have a finer mist for better coverage. 🚪 How It Stacks Up: Compared to standard bug sprays, Stem is a great alternative if you’re looking for something plant-based and effective without the toxic vibes. It doesn’t have the crazy strength of DEET-heavy sprays, but for everyday use, it’s solid. If you’re like me and want to keep the bugs at bay without dousing your space in chemicals, this is definitely worth a try. Just keep it handy for re-sprays during longer outdoor hangs. 🌿✨

It works!
This product does work pretty well. I've had drain flies come every summer and stay until winter. They drive me crazy! I didn't want to spray a strong, caustic, poison in my bedroom (they were everywhere!) where there's no windows or ventilation whatsoever. So I thought I'd try this and I am not sorry. It says to not spray it in the air and to wait for the insect to land, then spray the insect. I just sprayed my whole room anyway and it worked great there was only 1 tiny one flying around for the next few days, it was great! I've only had to spray it twice (the 2nd time was directly at one I saw). I'm not crazy about the smell, but it's a lot better than the strong chemical smell that would come with Raid or one of those products. It's that lemongrass smell. I only have 2 small issues with this product. #1 the trigger/sprayer. I actually like it because it's easy to use, but it's too easy is the problem. You're meant to push the trigger with your thumb, not pull the trigger with your index finger. Well, my genius self, didn't actually look to make sure it was pointed in the right direction and tried squeezing the trigger (like a can of Febreze). I sprayed myself directly in the forehead and top of my head. Thankfully I had the can tipped and didn't get my eyes, just my freshly washed, still damp, hair. So make sure you know what way the nozzle is loi ting before you spray. Push the button with your thumb, NOT your index finger. #2- all the oil everywhere! I sprayed the air in my kitchen and then almost bust my ass! The floor was so slick! I had to mop the entire floor with hot water and dawn dish soap. The directions DO say toward for the insect to land, spray it for at least a second, then use soap & water to clean the area. This is turning into a lot of work, just to kill a few drain flies. I do feel better knowing that im using a non toxic, safe for humans & pets, product. Overall, I'm happy with the results.

Sorry, not useful.
One of our screen had a hole that I didn't notice and hence 4 or 5 flys had made their way in. They were bothersome enough and numerous enough that I thought, time to get some fly spray and be done with them. So here comes Stem Fly Spray and I think, great, this will finish them off in short order -- just spray it around the area where the flies are and the deed will be done. Oh, not so fast, compadre; read the instructions carefully and there you will see that they want you NOT to spray this stuff up in the air -- it specifically says not to. WHAT!? thinks I. No, you are supposed to wait till a fly LANDS and then spray it DIRECTLY on the fly holding the can 18 inches away, it says. Problem with that is, flies are WAY quicker than the spray -- the spray never hits them because they are gone the microsecond after you press the spray button. Evidently they see the spray COMING and they are gone, zippity-split, before it even gets to them! Plus, half the time when you try to get get the spray can 18 inches to a landed fly, that speedster is GONE, just from your movement. They are not just sitting there waiting for you to spray them. I have not been able to kill a SINGLE FLY in at least a dozen tries or more for over two days. Not singe success! I GURANTEE you will be better off with a fly swatter than this product. Better still, find a fly spray that you actually CAN spray in the air where the flies are, you know....flying. Also, this stuff is GREASY...every surface I sprayed it on in my attempt to get of a landed fly (which, btw, they don't do that often) turned into a greasy mess that then had to be cleaned, so that makes it a no-go for a fly that lands on any porous surface...like most of what is in my house. This stuff is a FAIL on many levels.

Works amazingly well.
I hate fruit flies and every year I get inundated. Last year I battled them, but couldn't get them under control. I use the old vinegar with a drop of soap trick. That always worked. This time not so much. The population began to grow and spread outside the kitchen. I have cats and don't like using sprays, nor do I like the smells. But it was time to change tactics and because of it being safe for pets I decided to try. I worked. It was quick, and though has a smell, it's not too bad and doesn't hang around long. Neither did the fruit flies. I bought another bottle for this years incursion and needed very little when i got a few buzzing around. Didn't need much, it was controlled quickly.

Works but...
I brought in my plants for the winter. I was plagued with nets and black flies. They got so bad that I had to walk around with a mask on when I got near my plants for fear. They would fly up my nose or buzz in my ear. On top of sprinkling cinnamon in the soil to kill Larvae. I also put down my vinegar, dishwashing liquid and water solution and all the rooms of my House. I was surprised at how many I actually had. So I needed something else. I even tried the sticky traps. But they still existed. And then I sprayed this on my plants. This seems to work pretty well if it gets on the actual Insect. Like previous reviews, it does leave a oily residue on everything. So far, they have cut down tremendously. I still see 1 or 2 every now and then flying across my face. If I get near my plants. But it's only been day 2 Since I purchased this. It doesn't kill your plants. It actually makes them bright and shiny. So I'll continue to use this and see how It does for the entire winter. The scent is a more natural, essential oil smell. Sort of like a lemongrass.

Pretty good.
As with the Stem light I got, it hasn't solved my drain fly infestation, but it's brought it somewhat under control. As I've seen others mention, this stuff does have a greasy sort of consistency. In fact, sometimes the flies it kills seem to die from getting trapped in the residue as much as what's in the spray. Be careful of the surfaces you spray it on. I generally hit windows, painted wood (like doors) or brick & such that won't generally be visible. I imagine it could stain wall paper or maybe even painted drywall or whatever. Not sure on that latter count. It has a strong but not unpleasant smell that either dissipates relatively quickly or I became nose-blind to quickly.
