I don't have a picture of it, unfortunately, but there is a mini billboard along a country highway locally that says "Country Pest Control." Flanking the text is an illustration of a cow on one side and a horse on the other.
I've never inquired, but I'm assuming the cow and the horse are references to the "Country" and not to the "Pest" part of the sign.
Because, really, what do you even
spray to control pestiferous livestock? Or does one set out traps?
