0:00.0 | Hello everyone welcome back to the podcast Kevin here from epic gardening today we're tackling a really common recommendation in |
0:08.1 | DIY pest control |
0:10.3 | Etc. And that would be using some kind of dish soap in your mixture, right? |
0:16.0 | And so the question is, is this actually a safe thing to do? |
0:20.0 | Generally speaking, you have to go a little bit deeper than just choosing any |
0:26.4 | random soap and making some sort of mix like if you were to use something like |
0:31.5 | dawn or joy or palm, those are some really common dish soaps. |

1:26.1 | lesson is made by mixing together sodium hydroxide or potassium hydroxide with a fat. You get a sodium salt of a fatty acid. |
1:36.5 | That's the same ingredient in most soap and chemically they're very different from |
1:41.4 | detergents although they both clean things. |
1:43.0 | So insecticidal soap is made using only potassium which is a softer soap than a |
1:49.5 | sodium and it's just a little bit better to use on your garden because it's not going to do a lot of damage to the foliage of your plants. |
2:00.0 | When you're taking dish soap, aka a detergent, not a soap, right? |
