You'd need an arena-full of fingers and toes to count the number of insects in the average American home. (Not including the mites living on our face, chest, back, groin and buttocks.)
"There are in fact around 100 different species of arthropod — a category that includes spiders, insects, centipedes, and mites — that inhabit the average American home, according to the results of a biodiversity survey published in the journal PeerJ on Jan. 19.
"That's not a measurement of how many individual bugs are in each home; it's a measurement of how many easily identifiable species the researchers discovered when conducting what they describe as the first "comprehensive survey of arthropod life in contemporary human
houses." The total number of bugs is likely much greater."
