Thank you for the linseed oil suggestion, that sounds perfect for what I'm wanting to keep the natural aged look of the old wood. Yes, burning poison ivy just releases the oils into the air and then you have the blisters inside your nose and entire respiratory track. I've never HAD my lungs to itch before, but I don't think I want to try it, lol. I will be working (at my actual JOB, oh the horror, lol) until Thursday so I won't know how Esmerelda fared with the round-up and spectracide until then. I don't expect it to kill her, but right now if I was to try to attack her trunk, I might as well roll naked on her, lol. So even just defoliating her will help. I'm thinking the vinegar will be my next effort, as vinegar is cheaper than strong chemicals And if that doesn't do it, I am NOT above mixing some rock salt with boiling water and saturating her roots. Hopefully such extreme methods will be unnecessary. I also had suggested to me in my Alabama thread to consider taking some of the good boards down and create a couple of windows for ventilation and use the removed boards to help cover the holes. I really like that Idea and be doing some measuring Thursday morning. The rock foundation doesn't have any glaring holes that I've noticed, the lower framing boards are laid flush up against them and I'm planing on using some concrete pavers as extra security against the tunnelers. I will be taking pictures at the beginning and end of each work day or step so that I can post progress and get input as I go. I don't have much experience in construction or carpentry so any insights as I go will be welcome. Thank you all for your responses. I'm also banking on some chicken cooperation once I have Esmy cut back to the ground. Even if they don't EAT the poison ivy, I'm hoping the constant scratching and digging will proved an insurmountable burden for her.
