I am already battling the stupid things! I used vectra 3d this time on my girls. Just 1/2 a tube each. It is killing the ticks but not repelling them. I also started back on Minksheen. It can't hurt to use it. We have had so much rain here but as soon as it dries up little we are going to treat the yard as well. I live in the country so I feel your pain.
