## Overview

209 Systemic Pest Control is a 100% botanical, organic systemic insecticide that protects plants from root to leaf by distributing rosemeric acid throughout plant tissues. Safe for use around children and pets, it effectively repels and eliminates a wide range of pests including fungus gnats, mites, and whiteflies. Certified organic and biodegradable, it offers a long-lasting, EPA-exempt, and environmentally responsible solution for professional and home gardeners alike.

## Description

Insects destroy plant cells by sucking out their fluids or chewing up the cell walls. 209’s unique formula works by allowing the plant to uptake a small amount of rosemeric acid from the rosemary plant. As the plant distributes the rosemeric acid throughout its cell walls, a barrier is soon constructed that is harmless to the plant. When an insect starts to suck or chew on the plant it comes in contact with the rosemeric acid and causes the insect to stop eating and move on. 209 is made up of 100% pure botanical extracts that are highly water soluble.We process raw certified organic botanicals and herbs in-house, ensuring oils and terpenes have a consistent potency across all of our products. The botanical extracts are all food grade GRAS (generally recognized as safe when used as directed) materials that are fully biodegradable. It is exempt from EPA registration under minimum risk pesticide exempted under FIFRA section 25(b). It can be used on a wide variety of plants, fruits, and vegetables. 209 is powerful organic systemic insecticide which repels and kills spider mites, broad mites, russet mites, root aphids, gnat larvae, fungus gnats, white flies, cabbage maggots, and most boring insects.

Review: 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
Review: 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!
*by D***E on December 15, 2025*

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!
