I thought I had gotten rid of the mites on my birds and coop after using Permethrin 10 earlier this summer but it appears they're back with the cold weather, I'd like to avoid soaking the birds if I can since the temperature here in Vermont has only been in the 40's most days. I was debating between picking up some Permethrin powder to dust them with or ordering some Elector PSP since I'd only need to get them wet once, but I was looking online and found Martin's Pen Poultry Insecticide Spray which seems to be an already diluted Permethrin 10 that doesn't require fully soaking the bird. Has anyone had any experience using this product successfully, or would I be better off going with one of the other options?
