Natural Choice for Bug Killer

[This review was collected as part of a promotion.] The bug killer spray has its positives, including little to no scent that does not linger or irritate, it does ultimately kill the insects, and the spray bottle is easy to use. The downsides, however, are that I find that the insects did not immediately die and I was using a lot of the spray. Ultimately, the spray worked, but there are better bug killer sprays out there. If safe/natural sprays are a priority for you, this is a good option!

Natural and works

[This review was collected as part of a promotion.] This Stem bug spray is great to have on hand when I don't want to use the harsh chemical stuff - like when I have a houseful of guests with kids over. It's lemongrass oil based so the smell is one that I love. Just be aware that where you're spraying it could get slick bc of the oil base. We keep it outside when we have an outdoor gathering and if a line of ants forms, we kick them to the curb with this spray to keep them from taking over the party.

Safe and effective!

[This review was collected as part of a promotion.] With summer in full swing, I've had to deal with so many creepy crawlers!! This has been such a safe product to use, and it is very user friendly! The spray directly targets the insects and the results are immediate!

Pretty solid insect killer

[This review was collected as part of a promotion.] Sprayed this along some of our deck outdoors to check out the potency. Came back out a couple days later and found all of the dead bugs! Ultimately it works well, it's just a small amount at the end of the day. I would recommend a bigger package and then we'd be in the 5 star range!

Sprayed on and get results

[This review was collected as part of a promotion.] I received this product in exchange for an honest review. It was hard to get this product it showed up on the website but wasn't in the store. I didn't get to try it as long as I hoped to . I did try it on alot of things to give my review. The first thing is to read the directions. This product wont affect ant hills it is mostly for bug on sight contact. It must be sprayed on the bug many times and it gets the job done. The smell is non chemical so it doesn't leave a bad fragrance behind but it has an oily residue.The bottle is not heavy to hold and the tigger sprays consistently. I used it inside and outside you to have spray many times. When you spray it then you have to wipe it up because of the oil based residue. I tried it on flies and ants because its summer time. Its a good spray for small bug problems but not for ant mounds . I would use it for small irritating flies or ants.

An insecticide that promises and delivers🫶

[This review was collected as part of a promotion.] It's an excellent product if you're looking to get rid of certain types of insects. It worked perfectly for me personally, since where I live, there were certain types of pests, including field beetles. I really didn't trust it because I hadn't bought from this brand before, so I doubted its effectiveness. But, oh, surprise! The best against field beetles. It made them leave their nest, and I was done with them in a couple of days since they were a danger to my little children. On the other hand, I wouldn't recommend using it on ants since it smells similar to insect repellent. It kills the ants instantly, but in the long run, it attracts them more due to its peculiar smell. It's better to kill them with a specific poison for them, either granulated or a professional insecticide. I should clarify that it also helped me a lot with flies, moyotes, fruit insects, field beetles, and beetles! I loved it and would definitely buy it again. Try it and tell me how it went! Plus, its small, handy packaging makes it go unnoticed in the chemical cabinet✨️

Effective and safe bug spray for indoors and out

[This review was collected as part of a promotion.] This product worked well and quickly in my kitchen for killing some ants. The scent wasn't awful and not strong unlike some other bug sprays I have tried. It was nice to know that it was plant based which made me comfortable to use with kids around. It is a little pricey but I think it's worth it.

Have been using this more frequently.

[This review was collected as part of a promotion.] The best part is that it's pet friendly and that's why I've been using it more lately. It has a nice smell but it does leave whatever you sprayed it on with a shiny finish. Sp pros is it works has a nice scent and the spray is effective, packaging is simple but the con on this one is that shiny finish. It's not the worst thing I just keep wondering why some things looked wet.

Kills bugs, smells good, no poison!

[This review was collected as part of a promotion.] The STEM ant, roach, fly spray works well without using poisons. The bugs die within about 10 to 15 seconds after being sprayed. The residue appears the keep them away, as well. I used it on sugar ants getting in the house-or killed them and kept them away from the area for several days. It does have a strong smell, but it's a lemon grass scent.

Must have at all kitches and homes

[This review was collected as part of a promotion.] I really liked this spray! I used it for ants and little bugs around the kitchen and it worked super fast. What I love the most is that it's made from natural stuff, so I don't have to worry about using it around my kids. It doesn't have that strong chemical smell like other sprays — it actually smells kind of nice. I sprayed it once near the windows and baseboards, and the ants stopped coming after that. Also worked well when I saw a couple of flies and even a roach — just one spray and done! Happy I found something that works and is still safe and natural. Definitely keeping this at home always
