The 91% iso alcohol did kill them just wasn’t immediate but what I found out and will be using for instant kill moving forward is simple Castile soap or Br Bronners soap which is Potassium salts of fatty acids…all natural and is instant kill and cheap too.
I haven’t tried the milk mix. After finding what I did using the simple natural soap and water that’s what I’ll be using as of now moving forward. This is also supposed to kill WPM as well as other insects.
