If a Detection K-9 alerts on the scent of bed bugs and no bed bugs are found, it is not necessarily a ‘false positive.’ There is no perfect detection technology available however; research has shown that properly trained detection dogs and handlers are 90% to 95% accurate as opposed to human, visual inspection which is only 35% to 40% accurate at best.
We all want to SEE the bugs once a dog has alerted, however in cases of early infestation or where bugs harbor-age in cracks and crevices, they may not be seen until the infestation grows. It is a mistake to assume that because no bed bug is found that there are no bed bugs present and the canine alert was false.
