I think they lay down a scent that others can follow....I'm not into all the additional work you refer to.....AND It's of course in my bedroom area that they enter....I just kill kill kill....that's about it...it's me against them....one thing that has disappeared are their nests....they do no build them within shooting distance anymore...in the past, I've shot them in the nest, only to have them die, hanging over the side....a beautiful experience....I have little else to do, so I think that if they were not here, I'd suffer a depression....AND...I'm used to my sound machine...
