Gap behind house siding
Hello, we recently purchased a home just north of Atlanta that is about 15 years old. The home had the foam around the foundation which the previous owner removed because of the possible termite issues. I noticed today that due to the removal of the foam, I can put my fingers up underneath the siding pretty far in some places. I think this might be a reason why we have so many bugs in the house. I was planning on using expanding foam and then topping it off with caulking to waterproof it a little. But I was wondering, is it better to just stop at the foam? Does the house need the foam behind the siding to "breath" or get rid of moisture? Or any other suggestions on what I should do with this gap? Thanks for your help!
