Often on the Bedbugger forums, we hear statements like, “I see dark spots and saw a bug in my bed that looked like a bed bug, but I do not have any bites.”
In response, I used to say, “many people do not react to bed bug bites.”
I first formulated this response based on anecdotal evidence: people coming to our forums who knew they had bed bugs and did not react. And PCOs who feed bed bug colonies and do not react.
Then, after hearing Jerome Goddard put the percentage of those who do not react to bed bug bites at 70%, I cited him on that for a while.
Having heard other statistics ranging from 50-60% recently asserted by other entomologists in the media, I have recently been saying that “entomologists tell us 50-70% of people may not react to bed bug bites.”
And now, thanks to Renee’s well-researched post, which shows some studies suggest a small minority do not react, and in the absence of a more definitive answer, I am going to go back to the only answer I know to be true: “many people do not react to bed bug bites.”
I know you’ll want all the information on this from Renee, so check out her post here.
