i'v been reading about fumigating wood for boring insects and had a thought. i have read about ammonia being used under tarps and remembered what my folks told me about mixing household cleaners. bleach + ammonia = chloramine gas, very toxic. now dose anyone know what this mix would do to the wood? the gasses used to fumigate house is not suposed to leave residue, so i would think all gasses would do the same. any thoughts or ideas on this? for safety i would place a pan of one of the chemicals under the tarp, then with a funnel and hose pour the other.
