Sierra Natural Science - 209 - Concentrate Pouch - (Pack of 5) 1.25 fl oz (37 mL) Makes up to 32 fl oz

Bought one of the ouches of concentrate to help deal with the start of a spider mite problem I had on my rubber tree. Had some leftover and used it on my Monstera Adansonii which had what I assumed was a fungal infection of some sort (tons of crispy brown spots with yellow halos). It cleared up the fungal infection almost IMMEDIATELY. It’s been a few weeks and I haven’t seen ANY new damage appearing on the leaves. The bottle is definitely more efficient and easier to use than the concentrate in the pouch. But either way, this product absolutely works for pears and fungal issues and is now a staple in my houseplant care kit.

Funny enough, after leaving the 1 star review, and the package was postponed for 5 more days, the package magically showed up today. The product is great and I have no complains about it, I hope the seller pays more attention to shipping times and issues on the future. Updated to 5 stars because product is good.

Amazing. Helps keep spider mites under control.

I had several kinds of bugs beded into my Crepe Myrtles. This has put an end to all of them naturally. It took about three months but haven't come back. This doesn't harm the bees that feed on them. Please don't use a chemical type, it does matter.

I have over 100 indoor plants in my house and this is the ONLY pesticide that has kept all kinds of pests away from my plants. I used to use other types but none would get rid of spidermites. This one is natural and works with all those annoying pests.100% recommended

I have been using this product for all my plants (1 in soil and others in semihydro) for 3-ish months now. Throughout these months I have found seemingly thrips damage on some of my plants but no signs of the pest itself. Last week I found thrips larvae on a new plant (on which I haven't been using this product), and the next day on another plant next to it (been using the product for 2 mo). So far I haven't found more thrips on more plants after treating the affected 2 with insecticides.I was thinking maybe I had thrips at some point within my collection, and the product had deterred them from continuously feeding on my plants so they gradually died off. So when a new plant with tasty leaves arrived, naturally pests appeared.I know the situation doesn't sound ideal, but I'm happy enough with the product's performance. I think this is better than nothing for those growing in semihydro and those who can't buy the systemic granules (which I am both).

I've tried everything under the sun to get rid of the gnats that seemingly took over overnight. My plants were VERY angry about Neem oil, and some of them don't take well to Sahara-like soil conditions when trying to dry up the problem. Bless their delicate souls. Within a week of using this, I noticed a significant reduction in the gnat population. After 3 weeks, they're completely gone! Best. Product. Ever. Thank you Sierra Natural Science, you saved my sanity...and possibly my marriage 😂

This stuff really works well. It ended my year long struggle with fungus gnats.
