Keeping Wasps Out of Unvented Soffits
My house is a 30-year old timber frame house with open ceiling (no attic) – SIP panels for walls and roof. The soffits -most likely vinyl – are not vented. In the past couple of years the wasps have been getting into the soffits to build their nests leading to some intrusion of the wasps in the closest rooms. Most of the time I noticed the external activity before finding any wasp inside the house. The nests are most likely built in the space above the soffit as there are no visible nests in the house. Calling the pest company every year to spray their entrance into the soffit – once I find heavy activity from the outside – does not seem to be a good long term option – by the time you called them, the nest is already well established. Once the nest dies, a bad smell spreads to the closest room. Early spring I caulked the entrance path to 2 nests that were active last fall. I am not quite sure that will really help in the future or if it could be really done around the entire roof overhang. The result of this early caulking resulted in an increase smell coming into the house…which later subsided but seems to have returned recently. Are there any good solutions to limit the entrance of wasps into a soffit?
