Dogs have been used for their wide range of smelling abilities for decades.  From drug to bomb detection, k-9 units are an essential tool in many law enforcement efforts.  Some species of canines have been shown to contain over 300 million scent receptors in their nose (compared to humans 30 million).  These scent receptors help them track scents in the rain, mud, and snow while distinguishing even the smallest differences.

K-9 Detection is on High Demand

Another benefit to using k-9s during bed bug inspections is due to their speed.  While it can take 20 minutes to an hour for a human technician to do a through search of a room, a dog can accurately smell the presence of a live infestation within minutes. This is especially valuable for corporate clients that want to inspect multiple hotel rooms or apartment units in a single day.  Some dogs can search up to 200 rooms in a single work day.

How The Dogs Are Selected

What Happens on the Job

When a team of trained dogs arrives at a location with their handlers the team starts with some drills and warm ups.  The dog is introduced to the area and the handler makes sure they are focused for the job.  The handler will lead the dog around the inspection areas and watch for the dog’s signals.  Once the k-9 has found its target the dog will be treated and a visual inspection will be conducted by the technician.  The K-9 team will use methodical search patterns and avoid missing any areas with bugs.  Positive bed bug sighting will be followed up with a treatment plan to be finished later.  K-9 units can also be used after a treatment application to ensure that all bed bugs have been killed.  This post-heat inspection is recommended for anyone who wants to be 100% sure that the treatment that was applied was successful.  Routine inspections are often conducted at hotel/motels with the hopes of spotting any potential problems BEFORE guests do.
