Need help and advise on killing MITES ASAP

[cmom]

I had tried spray also and even spread some garlic and the coop is looking better I'm just still seeing some on my birds and want to help them get rid of them any thoughts...I've cleaned, sprayed, added some garlic to food, dusted, put nu stock on legs and more but I still see them on their feathers...

What kind of spray did you use?
