I applied permethrin as opposed to elector PSP or Diatomaceous earth. From what I’ve read it’s the higher route. Permethrin doesn’t quit working when it will get soaked (like diatomaceous earth) and comes in powder sort (as opposed to elector PSP). I found everything I needed at Tractor Supply Co. https://chicken-dash-game17157.smblogsites.com/36293201/rumored-buzz-on-chicken-dash-game
