I said *like* onto asbestos. It didn't it was.
The not subtle difference being, Parrots and the like don't roll face down in dust multiple times a day, they typically bathe in water.
I also imagine it was under the floor on the tray, where they couldn't reach it easily even had they wanted to.
Indoor birds cages also get cleaned regularly, due to the general filth that birds create.
Most indoor pets don't have issues with external or internal parasites to begin with anyway.
Indoor Aviary bird care can't be used to justify outdoor Fowl care, the two are very different.It's not really worth mentioning.
Can I ask how are you making sure they 'don't inhale it' after you put them back in the coop after spreading it?
Chickens dig and dust constantly.
They don't get to wear masks and their respiratory system is so much more complex and delicate than yours.
The production of d.e also leaves massive yawning pits in the earth that won't heal for centuries and disproportionate amounts of pollution in the water and air of surrounding areas.
I can't reccomended against enough, their are better, safer ways to prevent and treat pests but whatever floats your goats.
One thing I’ll mention is that the Harris company has been providing diatomaceous earth for over 100 years. If it were truly that dangerous, I'm sure our government would have banned it or at least required hazard warnings on the packaging. The pool grade may indeed have warnings. I've never looked.
I’ve heard there might have been poultry deaths linked to DE, but even if that’s true, the reports I'd seen don’t specify which type was involved, and pool-grade DE is definitely much more concerning than food-grade.
I mention aviary birds because I use it with them too (fruit flies are constant in the summer without it), and they’ve done just fine with it.
At the end of the day, we won’t see eye to eye on this one, and that’s okay. There are plenty of folks on both sides of the fence. I’m just sharing our experience, as we’ve had good results using it safely and successfully for many years, while you’re being cautious due to what you’ve read.
Like you said, “whatever floats your goats.”

I wouldn't hold my breath for our government to protect us from dangerous things (not before, and especially not now). Every protection we have was hard won with blood, sweat and tears, still lagging behind Europe, and whatever protections we managed to get are being destroyed right now. If we were in Europe, then yeah maybe I'd use a product more bravely banking on the government having banned anything dangerous, but not here. The mighty dollar rules here, and if something is dangerous but profitable, there will be a loooooonnnnnngggg and thorny road towards banning it.
