Red mites - I’ve recently got rid of my chickens. I noticed I’d got quite a few red mites in my coop so  I’ve jet washed my hen house sprayed it all a few times and the coop is now seems fine it’s on my patio it’ll be gone soon to a friend who’s fine about it and knows how to deal with and I’ve treated it all well but now where my coop was in my garden when I go and walk on the ground I end up with loads of these tiny mites on my shoes I think from jet washing I’ve ended up spraying them into the garden. How do I get rid of them or will they just die on their own? I don’t have chickens but I have a cat and 3 dogs and I don’t want them all being brought into the house..I’ve found the odd one on me since but only if I go outside. Having pets especially a cat I do fully treat my whole house every 6 months with flea spray and steam cleaning but what do I do about my garden?
