My question is actually WHAT kind of sevin(is it for gardens?poultry? other creature?)and where to purchase before I leave the house. I have had a heck of a week with gapeworm,roundworm and picked up one of my ee's today and she has LICE on her vent. gag. the chickens will ALL be treated with the inj. ivomec tomorrow and I ASSUME that won't affect external parasites. will treat with powder later. I have been a bad mom.
