My boyfriend and I bought a house about a year ago, we have pretty consistent water difficulties in the basement. Water seeps through our walls when it rains, and drains into our sump pump. During our home inspection, the home inspector found some signs of possible termite activity within the basement. The house was treated for termites prior to purchase.
We recently looked up at our basement ceiling and saw these fibrous wooden looking mounds. We weren't sure if they were some sort of nest, or strange wood fungus. The wood surrounding the area, is dry and doesn't seem to be decaying, but we've looked online for similar pictures, but haven't found anything. Does anyone have any idea what these things could be?
