    We're sorry to hear STEM Plant & Garden didn't keep your ornamental plants free of aphids, spider mites and thrips. As this isn't a residual product, it will only kill when sprayed directly on contact. As this didn't meet standards, we'd like the chance to make things right. Please give us a call at 877-869-7546 (weekdays, 8 a.m. – 5 p.m. CT) and mention reference number: 23222756. We look forward to assisting you.

    Very pleased!

    So far so good!! I had an issue with spider mites, and this has done a pretty good job of eliminating them. I read some reviews that others experienceed damage to their plant. Which I have not as of yet, I will update this review if needed. What I did was absolutely drench the plant with the Stem spray gave it about 15 minutes, saw where the spider mites were trying to escape to and congregating and drenched some more. Then I gave it about another 15/20 minutes saw no activity!! Then I completely sprayed the plant down with water to rinse all of the treatment and hopefully dead mites away. I read reviews where people said this really helped minimize or eliminate any damage to the plant itself. And it’s been about six hours since and I have not seen a single mite or web or anything! Which normally, even if I would run spray the plant down with water alone (since the mites do not like water or humidity) within an hour, I would see them rebuilding webs and moving around. Now I don’t!! I think it worked 🤞🤞 I am very pleased so far!!

    Works on roaches, does not kill gnats

    I don’t spray this on my plants… I see reviews saying it killed the plants, I’m assuming that was by spraying directly on. I use for just the surface soil or inside the 2nd container where roaches sometimes like to live. Kills the roaches fast. Does not work on gnats. I use diluted neem oil directly on soil and on plants for that- only in the evening, it will cause burn if applied during the day.

    It killed my plants. Now they are drying up and yellow. Sure my plants had holes but I would prefer this over what this spray did to my plants. Absolutely horrible. Do not purchase.
    1 reply from stem Team team - 1 year ago
    We’re sorry to hear about your experience. While our product has been tested on a variety of plants, some can be more delicate and may benefit from spot testing before full application. When sprayed once from about 12 inches away, we wouldn’t typically expect any issues. Since this didn’t meet your expectations, we’d love to connect and work with you on finding a science-backed solution to keep those bugs at bay. Please give us a call at 877-869-7546 (weekdays, 8 a.m. – 5 p.m. CT) and mention reference number 22874334. We look forward to your call. – Megan, STEM Consumer Care

    Should be called PLANT killer, not insect killer

    This product ruined my $150 worth of plants!!! It left them a spotted mess & dying! I'm absolutely sick about it. I would have much preferred a few holes in the leaves. The last picture shows the color of my beautiful flowers before this garbage left "bleach" spots all over them!

    Did not kill the bugs, but certainly killed my healthy plants in under 24 hours. This is not "plant safe". Price is also high for such a small bottle.
