My room has a moldy smell to it, we tore of the outside walls but we didnt see anything, except that the wood boards were not well sealed,and their were ants piles inside near the 2x4s of the house.I am not sure if thats whats making it feel and smell so moldy not to mention humid. I put ant poison to get rid of the ants but the smell still persists. I want to know if i were to seal the boards, would i be making the problem worse by not letting any air ciculate, or would that be the solution to my problem? I'd appreciate any response to my question. Thank You
