ivomec is an insecticide/wormer, not just a wormer. why i like it over sprays and powders is - it only affects parasites on the chickens. with the decline in the honeybee population i try to watch what i use now.
there are 2 different ways of looking at this:
you can dust or spray your chickens, and worm separately if needed. if you dont need the wormer it is probably a lower dose of poison to just treat the lice/mites.
if you know you have both lice/mites and worms or you are unsure, this is one poison with a 2 time application.
so, is it better to use one stronger poison 2 times, or a weaker poison several times? i cannot answer this question for anyone other than myself. i am not saying this is the best method for everyone else, its my method as the caretaker of 500+ birds. i do not sell eggs for eating purposes, and i usually dont sell my breeders for eating purposes. if i did sell a retired breeder, it would be in a "clean pen" for a month before its sold. by clean pen i mean a pen that does not get any medicines or pesticides - a pen for birds to be eaten.
i do agree other options should be explored, and i do as i can. but when i find something that works well for me, i do get a little hard headed LOL. i would love to see some research on spinosad, and how it does with chickens and killing lice and mites. i haven't been able to find any real numbers.
I totally get where you are coming from. I don't want you to think I am saying you are wrong. We each do what is best for us. I personally keep chemical/medicine usage to a minimum. If I could do everything organically I would but sometimes you just need to kill a bug.
