The first sign of bed bugs is the time to act immediately. The longer an infestation is allowed to exist, the more difficult and expensive it will be to eradicate. It might take up to several months to eliminate bed bugs if there is a large infestation. If you think you have bed bugs, the best thing to do is get an independent K9 to inspect your entire home. These K9s are trained and certified by NESDCA to detect the scent of live bed bugs. The K9 will be able to determine where and how severe the infestation is. Be wary of extermination companies that have a K9 in house because this is a conflict of interest. They tend not to maintain their dogs well and are financially invested in you being infested (even if you may not be). To be referred to a high quality, independent, NESDCA certified K9 inspection company, please call Pest Away at 212-721-2521.
