In the facilities' mock hotel rooms, trainers will hide live bugs for the dog to find in a simulated environment. The dogs in training will develop search patterns and learn to detect odors through walls and behind electrical sockets where they can easily hide.
Train a drug dog, a bomb dog, bed bug dog, or any type of specific scent detection. This is the way we train the dogs no matter what scent is the goal.
A trained dog is looking for live bed bugs artificially hidden in various locations in an apartment. The dog successfully found the hidden bed bugs in all locations in this case.
I work in one aspect of this industry, but I don't handle these dogs..that being said I have seen dog handlers using the bed bugs dogs in a demonstration situation. The dog (or it's trainer) failed miserably. I hid 3 vials with live bed bugs in a room, and the dog did not find ANY of them.
Put live bugs in containers, sealed with mesh, so that scent can escape but bugs can't. Put the bedbug containers with the food under a container. When the Beagle stops at or indicates a container with food and the bedbug sample, provide the food. Ignore if your dog stops at a container with food but no bed bugs.
Because we know our dogs can locate bed bugs, when a client asks us to re-train a dog to detect a second odor, such as truffles, narcotics, or even human remains, we know that the dog will quickly and easily find the source of the second odor, since it is usually stronger than that of a bed bug.
