What Actually You Need to Know about Bed Bugs Sniffing Dogs

  ALL INFO YOU NEED TO LEARN ABOUT BED BUGS FINDING SNIFFING DOGS

(My comments below are about bed bug sniffing dog teams generally, and are not specifically in reference to the firm or dog team referenced in the article.)
The most important thing for customers to know is that bed bug sniffing dog alerts need to  be visually verified — by this, I mean the dog handler looks carefully in the vicinity where the dog alerted, to find evidence of bed bugs.
As I said to Penelope Green in an email last week,

Dogs that are trained [well] can be effective in sniffing out bed bugs.  However, it’s important that when a dog alerts to bed bugs, its handler follows up by visually confirming the presence of bed bugs.  Without a visual confirmation, the customer has no way of knowing if this is a false alert, and false alerts do happen.

False alerts have led to customers spending thousands of dollars on treatments.    And in one case, a user of our forums received differing results from one bed bug sniffing dog after another (at hundreds of dollars a pop), as she tried to determine whether she had bed bugs or not.
A visual confirmation is the only way to be sure you did not receive a false alert.  This is not just my own personal opinion. It’s the opinion of others who know a lot more about this topic than I do.
One of these is Dr. Michael Potter of the University of Kentucky, one of the foremost bed bug experts on in the world. Dr. Potter concurs that bed bug sniffing k9s can be very effective, and as he says, he’s followed at least five teams closely while they were at work.
Dr. Potter says a good bed bug canine team can be especially helpful in situations like movie theaters, where a large amount of space must be searched. But Dr. Potter feels dog alerts should be visually confirmed with a careful search.
Watch him in this brief video from the fall 2009 New York Pest Expo (Bed Bug Edition), where in reference to this problem of bed bug sniffing dogs alerting (without alerts being visually confirmed), Dr. Potter describes a dog handler who marks each spot where the dog “signs” and does not visually inspect these.
In response, Potter exhorts handlers to “Show me the bugs!”
So, if you’re considering hiring a dog team it is especially important to talk to the handlers about whether they visually confirm bed bug alerts.  If they say this is impossible or unnecessary, remember that there are other handlers will do this, and it will give you peace of mind.  As Dr. Potter says in the video above, it is not always possible to find a bed bug (e.g. one hidden inside a box spring or sofa).  However, in many cases it is possible.
If a company tells you their dog is 100% effective, be vary wary. No dog (or human) is 100% effective in detecting bed bugs, and some are much less so.
If you hire a bed bug sniffing k9, here are some other things which would be helpful to ask in advance of hiring a team  I am paraphrasing the recommendations of a handler in our forums who goes by the username LVK9 (a Las Vegas bed bug k9 handler):

1. What is included in the inspection?
2. Do handlers mark areas where the dog alerts?
3. Do handlers visually confirm alerts?
4. What type of documentation is left with the customer?
5. How much time is included in the visit?
6. If the k9 inspection company is also a pest control firm, can you use the pest control firm of your choice for any necessary treatment?
7. If you choose to use a different firm for treatment, does the price of the k9 inspection change?

Other handlers suggested you may also choose to ask what the charge would be for a follow-up inspection after treatment.
One thing consumers should be aware of is that there are warring camps in the bed bug k9 industry.  One of the places the war has played out is on our forums, among handlers from different schools of thought; if you want to ask questions of those in the industry about differing approaches to dog training, certification, or protocols, this forum thread is one place to do so.
Except for this June, 2009 article from the Atlantic, the news media does not tend to mention that there are various schools of thought about bed bug sniffing dogs; instead, articles typically refer to only one team or one trainer’s dogs and protocol.  As the Atlantic story clarifies, methods and protocols can vary a great deal.
Handlers with dogs from one trainer or another, or whose bed bug sniffing dog is certified by NESDCA, or not certified by NESDCA, are often adamant that what they have is what you need.   So let me cut through some of the politics for you:

1. There are a number of companies which appear to effectively train bed bug sniffing dogs (including J&K Canine, who trained the dog mentioned in today’s NY Times article, Florida Canine Academy, and others).  The name of a trainer alone is not insurance that the dog is effective, since continued training and effective handling are key.
2. It’s also not enough to ask whether the dog is “certified;” it’s my understanding that effective bed bug sniffing canines may or may not be certified by NESDCA.  Florida Canine Academy also re-certifies its dogs yearly. Additional certification bodies may be springing up as I write this (remember, this is more or less a brand new sub-industry in canine scent detection).  Recommendations from other customers and a confirmation that the handler visually confirms alerts should do a lot to guide you in selecting a dog.

Keep in mind that bed bug sniffing dogs can be a wonderful tool, but they are not all alike.  And remember that every time one sits or scratches or paws at something in your home, it does not necessarily mean there are bed bugs there.
