Being in the Bed Bug Scent Detection biz, K9PI sought out this burning question early on, can bed bugs transmit viruses. The answer simply is that while it has not specifically been unproven, it is not likely. The coronavirus, or Covid-19, is a respiratory virus, and the primary mode of transmission is through contact with droplets generated when an infected person coughs or sneezes. According to the Entomology Department of Purdue “no evidence of disease transmission” has been linked to bed bugs1.

Many people know that bed bugs inject an anesthetic in their saliva when biting (that is why you don’t wake up!) so it would be easy to imagine plausible virus transmission if an infected person was bitten just before a non-infected person. There is real concern about this because after all, the origination in humans is by transmission from an animal. However, there is no scientific evidence that Covid cells can thrive or even multiply in the gut of the bed bug.

Memos written by the top research doctors around the world stress that while there is no evidence so far, the public should be aware of the other human health hazards that bed bugs present.

For example, several studies have conclusively linked bed bugs to Chagas disease, which, if left untreated, can develop into a serious lifelong illness2.

There are many other gnarly diseases that bed bugs are suspected to transmit though more studies need to be done. Regardless, bed bugs remain listed as vector pests by the NMPA (national pest management association)3.

So the bottom line going forward is, K9PI expects there will be a “new norm” of increased hygienic protocol implemented by businesses and municipalities, with bed bug detection and removal included in that priority.
