Personally I use none of the above and have noticed no critters on my chickens, just processed some and no bugs. I do use deep litter and have a bed of wood ash for dust baths, maybe the two help.
I have never heard of worming chickens until BYC and have had no problems. My father raised chickens all while we grew up, never wormed or used DE, and no sick chickens.
From what I've read DE is bad for the good of deep litter...?
Do the research, don't use my opinion on what works for me if you are uncomfortable with it, there are many advocates that swear by this or that. Some have proof DE works, some disprove it's effectiveness. Do the research and what's best for you.
Boy ain't that the truth?
Anyhow, since it was asked.
I use DE when cleaning my coop. I dust all the wet spots if any and the roost bars. I also dust into the next boxes when cleaning them and toss some on top of the hay/straw/shavings. I know some say it doesn't work but I can afford it and what does it hurt. I've not seen any cooties. Also a good rub of vaseline or bag balm on the legs and feet can't hurt. Cooties some out at night so I've read and like dark damp places. You can buy DE at some feed mills or order it in a 40-50# bag.
As for the Ivermectin I use the liquid pour on stuff. A bit expensive but it lasts in the fridge. I use an eye dropper and wear a headlamp. I go into the dark coop and go down the line putting it between their shoulder blades.
Now Iv'e seen this advertisement in BY poultry mag and intend to try it. "Zyfend A." It's a wormer and not to expensive. I refuse to use anything that requires me to toss eggs for weeks as I don't get many and can't afford to do so.
As Beer stated there are different opinions about these matter but I say do whatever lets you sleep at night. Not everything works for everyone and their situation, so I only offer my system as a suggestion. Of course I've never seen cooties nor piles of worms so take it for what it's worth.
As always remember "an ounce of prevention is worth a pound of cure".
I wish you well,
