Bed bugs eat blood. Red cells do not contain DNA which can be hijacked by the SARS-CoV-2 virus so the bugs should not have any viable virus unless the bug is covered with infected droplets of someone's cough. That seems highly improbable.
Bed bugs are not known to spread disease. Bed bugs can be an annoyance because their presence may cause itching and loss of sleep. Sometimes the itching can lead to excessive scratching that can sometimes increase the chance of a secondary skin infection.
A common concern with bed bugs is whether or not they transmit diseases. Although bed bugs can harbor various pathogens, transmission to humans has not been proven and is considered unlikely.
However, blood also contains some macrophages which have been shown to possess ACE2 receptors which could lead to the macrophages getting infected though surface expression is low. One would have to posit that the virus enters the bug's gut but somehow leaves again, and somehow reaches the bugs' beak while being unable to replicate.
To further put this into perspective a cc of blood has usually less than 15,000 white cells. The volume of blood suckled by a bed bug is a way lot less, and macrophages are further sparse in white cells at 5%.
