Someone told me that washing up liquid is good to put on plants to kill pests. is this true and safe? How dilute shoud it be and is it poured or sprayed? Does it matter what brand |

I have done it in the past but it has to be really diluted a lot otherwise it burns the plant. I would spray as thats gentler as well. |

I've used soap water from a wash basin after doing the Dishes... pour or spray... the washing liquid is already diluted and its great on Roses |

I've used it on window-sill basil that was infested with aphids. I put a drop of washing up liquid in a big jug of water and dipped the plant, upside down. Apparently, the detergent wrecks the aphids' waxy coating and they then die of dehydration. |

Yes, it is absolutely possible to use liquid dish soap as a pesticide. I would not use a strong solution though. Usually a few drops in a gallon is all that is needed. You can also put in a few drops of cooking oil, too.
Pretty much, that is what the stuff on the store shelves is made of...just costs a lot more than making it up yourself! |
