First, you kill Mr. Bushy Tail, and show the lady of the house all those horrible lice that live on the skin of those filthy rodents. Hold the dead squirrel with needle nose plyers whilst wearing rubber medical gloves to freak the wife out, whilst showing a dead squirrel carcasse with crawling lice.
Tell the lady of the house that it appears the squirrels are interested making a nest somewhere in the house or garage. Remind her of all those lice crawling in her beautiful home from the squirrels. Remind her that they are innocent God's creatures and that it must be her choice to remove them.

Maybe the lady of the house will relent. With her permission to liquidate the squirrels you can now send the vermin "swimming" to their new residence if the river is close to you.

Any goose problems down your way? I hear the geese in Okotoks have become louts and don't want to fly south any longer.
