First attachment is a closeup of small patches of brown powder at the base of a D.Fir next to the house. Saw ants there last year and applied some chlorodane and have not seen an ant since; however, some of these bark granules still appear occasionally, and there appears to be a small cavity in the bark right at ground line, which would indicate a critter?.
The 2nd attachment is the tree location (framed in the breezeway) and relationship to the house, which is why I do not want anything to happen to this tree, as it is the main reason air conditioner never needs to be turned on.
I have watched these trees next to the house for grow for the last 33 years - when the foundation was dug, started 30 feet out and dug to within 16 feet without hitting any root leaders, so do not beleive it is root damage. Possibly roots have now come to the basement wall, but no wall problems. Does the small amount of negative PH from the basement wall have any effect?
So, assuming ants and other similar phylum critters have been dispatched, what does the bark powder indicate and is there anything recommended (other than more chlorodane) ?
PS: Can one attach more than one pix per post?
