Alaskan, I have said it many times on these forums that one of the easiest, cheapest, safest, and fast acting methods to treat an infestation is Sevin dust. They sell 3 containers in a bundle at both Wal Mart, and Home Depot. I used to use an old pillow case, pour the dust in, hold the opening closed around the chicken's neck, don't cover the head, support the bird, and do a shake & bake. I found it to be much easier to just get a good sized pan, or shallow bucket, pour the dust in, set the bird in, and scoop it onto the bird. REPEAT in 10 days. I also like to mix liquid Sevin and lightly spray the roosts, empty nest boxes, and poop boards. The key with Sevin is to REPEAT in 10 days. Yes, I've read about all the organic ways to do it, but I personally won't use most of them. Either they are very harsh on the skin, or they don't work. There are a couple that might be a good preventative, but are failures for treating an actual infestation. Chemically, it's safer than a lot of the other stuff that I see recommended. It's not strong enough to kill the bug eggs, and there is not enough residue to kill the hatchling bugs, which is why it has to be repeated in 10 days.
