Works Great!

[This review was collected as part of a promotion.] Really works well. I use this on the patio to keep ants away. I like that it's natural plant based so i don't have to smell unwanted chemicals. This works just as well but without harmful chemicals

Kills them in their tracks.

[This review was collected as part of a promotion.] I've bought this several times before and it works great. I brought a plant inside and the amount of ants that were living inside that plant would surprise you. I woke up one morning and they were everywhere. I grabbed this spray and it literally kills them dead on. I set out those bait traps too but every morning I would have to grab this spray and kill the ones right there at the plant and then vacuum them up for like a week. Finally they went away, knock on wood.

Great all natural bug killer

[This review was collected as part of a promotion.] I love to use natural bug killers. I have 3 dogs , and I don't want to take the chance of them eating anything with pesticides on the. I was very pleased with how the product worked. I had some bugs on my indoor plants, and I sprayed the soil around them, and it took care of my issue. The smell is also not bad. I will be a repeat customer for sure.

Works Great!

[This review was collected as part of a promotion.] This works great! The sprayer is the best- comfortable and easy to spray. I sprayed a fly that was hovering over my sink, and the fly dropped right down with one little spritz. Scent is strong but tolerable. Love that it is safe for indoor use.

No more flies!!

[This review was collected as part of a promotion.] Ugh, these ants and roaches have been driving me crazy! I'm trying out this new stem spray and hoping for a miracle. We both did not mind the scent one bit, and she didn't run sooo. Summer time is no joke for my fur baby and insects just love to antagonize her.. I'm so ready for not only a pest-free house but a pest-free yard. #pestcontrol #ants #roaches

Works on contact

[This review was collected as part of a promotion.] Thank you, Influenster for letting me try this product. The Stem , ant, roaches and fly killer works fabulously. This year has been a rough year for ants and flies. This kills them on contact. There is no harsh or chemical smell and it doesn't take a lot to do the job. Therefore it is an awesome value. I highly recommend it and I'll buy it again when I'm out.

Effective

[This review was collected as part of a promotion.] This spray is effective and refreshing alternative to traditional insect repellents. I was initially drawn to it because of the plant based formula which felt like a safer choice for indoor and outdoor use especially around my family. The scent is noticeably different from harsh chemical sprays. It is light and natural without that overpowering chemical odor. It does a its job of eliminating ants and roaches fairly. The effects remain until next day. I needed to spray a bit more generously to see results. The bottle is easy to handle and the spray nozzle delivers a fine mist that covers a good area. I like the balance between eco-friendliness and efficiency. This is a good option for a less toxic way to keep pests away from home. I recommend this to control bugs and ants.

It works!

[This review was collected as part of a promotion.] This all-natural pest deterrent made with essential oils, especially lemongrass, is highly effective against insects and rodents. It works instantly on contact and repels pests with its strong scent, which is the key to its effectiveness—despite being overwhelming and potentially headache-inducing if overused. A little goes a long way, making it cost-effective and easy to reapply when needed. It eliminates the need for traps or toxic sprays and can be used strategically on absorbent materials for long-term protection. The only downside is the oily residue, which requires mindful application.

Effective and Safe Bug Spray

[This review was collected as part of a promotion.] The summer heat and humidity is here and so are the bugs. I've tried endless sprays, repellants and formulas to get rid of bugs, flies, roaches and other pesky things in my home but none have seemed to work that well. This spray was a big surprise to me. Very pleasant and light scent. A science-backed and proven formula. The use of botanical extracts and no other unnecessary, harsh chemicals. The best part, a safe and effective formula. I used primarily indoors around the doors and windows of my home and let sit for a few hours. I immediately saw a decline in the number of bugs entering or appearing out of nowhere in my home. I almost saw them disappear completely! Best of all, there was no awful scent or residue left behind. I love this stuff and would recommend.

Good value and effective

[This review was collected as part of a promotion.] I'm genuinely impressed with its performance.It's reassuring to know that it's safe for use around people and pets. The spray works quickly, killing insects on contact, and leaves behind a fresh scent without any added dyes or artificial fragrances. I've found it particularly useful for indoor use, especially in areas where bugs tend to gather.
