Does anyone routinely dust their chickens or coop with food grade DE? ALSO do you use poultry spray as preventative measure just in case?
I don't think I have mites in the run but I want to do a preventative spray and cleaning
I have, and use DE (food grade) but am careful/cautious on how I use it.
I place a thin layer in my coop, and pigeon loft floor. (like flouring a breadboard) Then I cover that layer with a slightly thicker layer of Sweet PDZ. (about 1/4 inch). Then goes bedding. I usually use hay, but do have pine shavings as well.
The DE on the base is to control whatever insects choose to visit. The other layers are holding the DE where it does not form dust.
DE dust is not good for us to breathe. (read the cautions on the bag). It is best to minimize things that are less than ideally safe.
DE is not toxic, but under a microscope reveals it to look like sharp crystals. It is these crystals that cut up the insects exoskeleton shells.
The coop, when I do an annual (give or take) SUPER CLEANING, everything is removed. (bedding, nesting material, and anything movable) I hose flush everything, and then spray everything with Laundry Bleach. You need to be careful not to get it on your skin. The 5% bleach is strong enough to cause burns. Flush with water if on skin.
(I know most people are aware of this, but I still like to mention it for some that maybe are not
)
Obviously your chickens are nowhere near the coop when doing the cleaning. When the bleach dries, danger passed. Your nose will tell you also.
Bleach is a GREAT SANITIZER.
