What is the best thing to spray for ticks around dog kennels?

I use the purple cattle tags from tractor supply. I cut them in half. I don't have to pick ticks off my hounds. Hope this help

Try spraying diesel around your pens it has help for me n the past hope this helps Christi

when you spray use any thing for ticks. the key is to spray up on trees and houses about four feet. that gets them where they live. hope this helps.
