Professional lab testing the modified glue board trap
Over the years we have used glue board traps extensively and trained landlords on how to build and use them as well. We have noted that it is entirely possible, given the right circumstances and tenant cooperation, to remove all bed bugs from a suite with nothing more than heat sterilizing the beds and stuffed […]
How long do the glue board traps last?
There are a number of factors that influence how long a glue board will be effective at catching bed bugs. When new they work very well but age, UV damage, dirt, and the severity of the infestation play a role in their longevity. I have noted that glue boards exposed directly to sunlight turn yellow […]
Temperature and baiting bed bugs
We know that the bed bug metabolism speeds up in warmer temperatures causing more frequent feeding and shorter life span. On one occasion I took advantage of that quirk when a man in care facility insisted on keeping his suite at 30 celcius on a regular basis. The infestation was well advanced which usually means […]
Bed bugs, businessmen, and the Intellectual
I spent many years in University and one the most enduring tidbits of knowledge I gleaned came about through Edward Said’s lectures entitled “Representations of the Intellectual.” Said suggests that the role of the modern intellectual is to move beyond self interest and speak truth to vested interests on the “basis of universal principles” (p11). […]
Bed sized bug trap – an evaluation
Last week I had an enquiry on my web site about a product called “bed sized bug trap”. I didn’t know anything about it so I looked it up. Apparently it is a large bed sheet that drapes over the bed with a sticky barrier around the perimeter. The theory is to prevent bugs from […]
Moving without bedbugs and customer language barriers
Several years ago I established a partnership with a local nonprofit group that assists newcomers with adjusting to life in Canada. The non profit deliberately hired a wide variety of employees with a range of language capabilities to facilitate their work so I thought we could partner effectively with translation. Moving without bed bugs actually […]
Dragnet (pemethrin) and Tempo (cyfluthrin) – advantages and disadvantages
I switched from Dragnet to Tempo many years ago because Tempo appeared to have a better residual. But I still use Dragnet from time to time. The following are the advantages and disadvantages of each: Dragnet positives: dries clear so it is easier to make applications look invisible label directions are more permissive allowing broader […]
Field observations of pesticide resistance
I was asked to treat a suite that had been unsuccessfully chemically treated for two and a half years – that would be 30 unsuccessful treatments. The landlord hired Bug-n-Scrub to spend an entire day vacuuming, steaming, and doing laundry and the next day I spent 1.75 hours thoroughly chemically treating the suite with Tempo […]
Can bed bugs walk on a razor blade?
I have noticed that bed bugs don’t easily fall into pitfall traps. The primary behaviour is to hang on to the top edge of the trap and go round and round. As a lark I decided to see what would happen if I made a pitfall trap out of a box cutter blade – […]
Why do bed bugs disperse?
I specialize in inner city multi family bed bugs and have treated thousands of suites to date. Almost from the very beginning we chose to treat only suites that had actual bed bugs and simply monitored surrounding suites with climbup interceptors or modified glue boards. We found that dispersal to neighbouring suites was actually quite rare […]
