Same Fireplace problem... The fireplace walls are exterior walls (one of EAST SIDE and one on SOUTH side of house). These have fiberglass insulation, sheet rock inside. Ceiling is void between first and second floor; wood construction. Tyvec and Hardy Board Outside with PVC Trim. Wood fence abuts to house at this corner, but is joined to meet corner PVC trim with two PVC blocks; one midway up the fence post and one on top. This was done to prevent ants. Fence post does not go into ground, it was sawed off when installed to prevent infestation. But, we saw tiny ants and flying ants all over this spot and up wall and fence the first night they were swarming. How could they be outside swarming and coming inside through the crown molding? Along this side is also an 12" deep of gravel so rain does sit on patio. Plus an underground (12" down) gas pipe that comes out wall from Fireplace and down along patio. We see ants coming out of ground right here and around the corner on the other fireplace wall. Help!
We would recommend using Phantom Termiticide/Insecticide. It is an insecticide that is mixed with water and sprayed along the baseboards and cracks and crevices where the ants are and walk. This can also be sprayed outdoors. We would not recommend spraying this directly into the fireplace but can be sprayed around it. Also, this product can be used outdoors around the perimeter of your home. Please let us know if you have any additional questions.
