Sierra Natural Science - SNS-209 Systemic Concentrate -1 Pint

This is NOT for active infestations, it’s a preventative. It can take up to a few months for the plants to absorb completely depending on watering need etc. But I will never not use this in my regular watering/feeding. I have over 200 plants and my fungus gnats are almost nil and not a mite or mealy or aphid (knock on wood) in sight.

I had a mite problem this summer with the mild winter we had, this has been a great product! I use it in my house with my dogs/cats as it is not poisonous like others! It doesn't smell bad either!

So far so good, it was easy to use the instructions were clear to use. I diluted the sns-209 systemic with water and fertilizer and my plants love it the best part is it repels those nasty pests from attacking my indoor plants. The smell it’s not that strong which I like. If you are dealing with mealybugs , thrips, fungus gnats and spider mites this might be the solution to keep them away from your plants.

Gnats disappeared within two weeks. Just needed two watering cycles. Also use Olivia spray to put some on affected plants. Needed very little of it too.

Use this every time I water my houseplants as a preventative. I generally do not have pests. Never have noticed any ill effects on my plants either.. no chemical burn, shock, etc. Smells good too. Only 4 stars because I've got scale bugs on a staghorn fern and mealie bugs on a Hoya despite watering with this stuff regularly. Maybe its not meant to defend against those ones not sure.. I was u der the impression it was for all houseplant pests.

Luckily I heard about this early on in my plant era. I haven’t had a single pest on my houseplants and now that I think of it, my succulents didnt have a summer invasion of mealy bugs like they normally do. I dont always use this on my succulents but i did use it pretty frequently throughout the summer just out of pure laziness and not wanting to mix up 2 batches of water. So my succulents got my houseplant water which has 1/2 strength fertilizer and SNS-209. I also use Microbe Lift liquid in the dropper to prevent fungus gnats which is amazing at keeping those guys away. Im not sure that the SNS would treat pests but it definitely works for prevention. I haven’t noticed any scent when using it either which is nice

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

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

Good stuff. Expensive when bought in the UK but hard to find at the US retail price.

There was a problem with Royal Mail delivering this item and the company ASBSMT LIMITED contacted me and sorted it on their end so I was able to get it delivered to a Royal Mail depot for me to pick it up and refunded me for the item even though it wasn't their fault just as a kind gesture for the hassle of Royal Mail's mistake. Excellent and friendly customer service as for the product it may be too early to tell with my plants but I don't have any mites or anything so I assume it's doing its job well!
