Red mite in the ground

Following up from Kym503's red mite thread, I have read lots about what you can clean and treat the house and hens with but - is there anything you can sprinkle on the ground to kill any laying dormant there too?  Will Stalosan F get the little b*****s?

Red Mite need dry conditions. They do not live outside. Do you mean that you have an earth floor to your house? Most houses with earth floor are portable. After spraying move it. If it is a fixed structure you would need to use a fairly strong solution of jeyes fluid or potassium permanganate and really soak the floor. And the chicken would have to be kept out until the soil is friable again. Difficult one!

Thanks joyfull, I did wonder whether I could just soak the ground around the house with Poultry Shield.

No animartco, I just meant the ground around the coop.  I have taken the coop pretty much apart and sprayed it all and Diatom'd it all but thought that, while I was doing that, some of the little critters must have dropped onto the bare earth (it used to be grass but is now long gone) and bark chips that I have on the ground in the run.  It seemed mad cleaning all the coop if the ground around was then infested and they just came back in! 

Thanks for the replies.

Sadly though, the rain can come down all it likes but it doesn't wash the incy-wincies out?
