Review: Vital if you have a lot of plants - I have a lot of plants. Recently, and for the first time ever, I got pests. I found spider mites on my Rhipsalis Paradoxa. Absolutely gutted but I showered it then drenched it in this spray, then repotted and sprayed it again. Spider mites gone. I now spray that cactus with Neem oil occasionally and I’ve had absolutely no more pests. This spray doesn’t harm the plant. I spray new plants coming into my collection and then isolate and spray again a few days later. I also give my established plants a quick spray about once every 2 months just to prevent pests. Inbetween, I wipe leaves with a clean damp cloth and shower larger plants as a precaution. It’s a big old bottle too. Value for money. It doesn’t stain windows either, at least it hasn’t for me. It does have a strong smell but it’s just soapy and quickly disappears. Don’t forget to add kettle-boiled cooled water to the bottle when it’s almost finished and get a few more weeks out of your spray before re-ordering. Highly recommend Review: Didn’t kill gnats but did kill leather jackets - I used the spray to help control a fungus gnat infestation & although it didn’t help with the gnats it did kill the leather jackets that were in my outdoor plant pots. So, I guess it’s a win?! They came to the surface then shrivelled up & died. I’m going to order a bigger bottle. ## Features - Use biocides safely.

Leaves had fallen off plus a bud or more - I used this soap as it was cheaper than other ways and it's worked wonderfully - I sprayed all the fallen leaves and gathered them for the black bin. ## Frequently Bought Together - Potassium Soap - Horticultural Soap - Organic Insecticide - Aphid Control - Pest/Bug Spray 0.5L - 100ml Neem Oil - Premium 100% Pure Multi-Use Oil for Garden - Plants - Home & More - aonova Fruit Fly Traps, Pack 30 Yellow Double-sided Fungus Gnat Sticky Catcher for Plants Indoor and Outdoor Insects Fly Control - Non-Toxic, Waterproof --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/384658283-potassium-soap-organic-bug-spray-and-horticultural-soap-for-plants](https://www.desertcart.co.za/products/384658283-potassium-soap-organic-bug-spray-and-horticultural-soap-for-plants) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-05*
