It is black and will commonly be seen entering structures in mid summer as their populations increase and they are looking for breeding sites and places to lay eggs. They will not successfully lay eggs indoors but they become unwelcome visitors in homes and especially commercial locations with larger entry doors and with damaged door sweeps. These beetles will migrate into structures in the evening and many an office employee has found them under their desk when they arrived for work in the morning. Control is a process of seeking out and elimination of external breeding and gathering sites. Indoor control measures are usually restricted to glue boards and repair of door sweeps.
External control is the most effective because it gets to the source.
This is a seasonal problem and not a species that will infest a structure long term. Typical control period is June thru September. Bark beetles are a common sighting in homes that bring in firewood during the winter to burn. These beetles will be dormant under the bark and will become active when brought into our warm homes. Bark beetles are not an infestation risk and the solution to them is to simply bring the wood directly into the house and immediately burn it.
