Ok, I try not to use chemicals if I can find an alternative, but sometimes they are my last resort. SO, I have plants and fruit trees and stuff around the yard and I plan to let my futtute geese and runner ducks graze... I have fenced my garden off and fruit trees have a cage around them. But I do use mothballs around some plants to keep the deer from eating everything, I also sometimes use garlic, dried egg spray on stuff. Sometimes I use DE, and on rare occasions I dust the dog yard with flea dust.(Frontline didn't work last year and 2 of our dogs are allergic to fleas, had to change to Advantage) I also use a Fire Ant bait on mounds , which I am trying to get rid of before the geese , ducks are grown and out for grazing. Sometimes I use the FireAnt dust, that they track in the mound and it is supposed to kill them, it works fairly well too.
