Great for fungus gnats
I bought this to use for my indoor houseplants. I had a bit of a fungus gnat problem but wanted something more pet/child friendly. This checked all the boxes. Used as instructed and has helped eliminate my fungus gnat problem, it was slower than most traditional systemic but it was a good alternative to using a harsher systemic in its place, it was a worthwhile trade off. Pretty easy to follow instructions and it worked really great for me. Hoping to use this longer term as a good prophylactic treatment to prevent any future pest issues

Finally, something organic that really works
Works great. I've been searching for years for an organic pesticide that works on fungus gnats, white flies, scales and thrips. Neem oil and dead bug work somewhat for somethings but this absolutely eliminated them all (been using for 1 year). At first I thought it wasn't working but it takes about 5 waterings (once a week root drench) and they disappear. I stop after 5 weeks and only use it if I see an infestation starting. When I had a heavy infestation, I used an initial foliar spray of dead bug and initiated the root drench cycle. I have some potted plants outside and it seems to deter reinfestation for about 3 months.

It works!
Battling pest that move into/onto your plants, especially when housebound in the winter had become a problem. I recently started using this SNS-209 Systemic Concentrate when watering all of my plants. I like the fact that it is an organic systemic pesticide that will work on spider mites, scales, thrips, and fungus gnats which makes taking care of a large collection of plants easier. It has a pleasant smell, is safe for my dogs and does the job!

So far so good
So far so good 👍 The real test will be spring time when the houseplants start growing. Am really anxious to see if the gnats will be reduced.

Safe systemic for indoor houseplants
Takes a long time to work. I use it prophylactically now. For active infestations, I would use a different systemic. However, this one is truly organic, OMRI certified, and safe for pollinators and hummingbirds.

doesn't work against spider mites or aphids
Draining soil, spraying foliage, once a week for three month - spider mites and aphids seem not to notice it at all. Indoor plants here.

Highly recommend
Super pleased that I followed somebody’s recommendation. I have been dealing with mealie bugs for 6 months. This has done a fantastic job in eradicating them. I will never be without them in my plant supplies.
