I use it for red mite! I buy the big bucket, food grade off amazon. Wooden pen and the little cretins get in everywhere! The house was built from scratch using decent treated wood and creosoted!! Then creosote was stopped and replaced with creocote. Useless! In the days when I used creosote (managed to get some off a fencer guy) the house needed 3 days to dry and stop smelling. NOT ONE MITE!! And the blasted stuff lasted. Now, due to the lack of preservatives, I use dark oak Cuprinol and on the outside, the house and run, also treated (8 foot high!!) look pretty!! When you open the door, another matter!
Got new birds this year, painted all. Inside, to make it look pretty, it was treated in white for the next boxes, pale lemon for the roof and the wooden floor, the perch was pink, the droppings shelf is blue as is the ramp up to the shelf (Hen house is 6ft high x 6ft long x 4ft wide built against the shippon). When the chicken guy come with my girls he smiled when I opened the door. "I use that he said!"
Yes, pretty colours with liberal sprinkling of DE on shelf, in crevices, amongst the shavings bed, on the floor etc. I do put some in the dust bath (also got its own roof and frame painted pink!) but I find they prefer soil off the mole hills!
Since I've been doing this I've not had the familiar crawling sensation on my arms. Now my dad is adamant that he can't get rid of his mites. His birds have wooden nest box and wooden perches, that he soaks in water daily trying to drown the mites. His pens are old pig buildings so are concrete walls and floors. When I have suggested he buy the DE, not only does he gasp (the thought I spending money.......) but he says he hasn't got it. He has 2 pens of 12 birds at any one time. I have 4 girls and that's it.
I've tried the sprays, barrier red mite powder etc but I find the DE works and have been known to grab a handful and the bird at the same time. She squarks and squeals but then usually shakes herself up whilst giving me a dirty look. But she aint scratching!!
The only other person who has my eggs is my sister and a mite on the egg when its one of mine in my cupboard is one thing but she has passed comment before now that when she's opened the box, she can see movement. (Dads eggs). They are skin toned so aren't sucking, but they stay in the boxes which are reused. This isn't recent but its not nice.
