new treatment poses concerns for sprinkler systems
With a current
national resurgence of bed bugs, along with a decrease in effectiveness of
treatments such as chemicals and pesticides, pest control companies are relying
on a new technique called Heat Remediation to scourge the unruly pests.
relies on piping hot air into the room and heating its core temperature to 120
degrees Fahrenheit (48C) or higher, causing the bugs to inevitably reach their
thermal ‘death point’.
effective on bed bugs, the process of heat remediation does not come without its

sensors, or worse, damaging or setting off the sprinkler system,” said Greg
Patterson, former engineer and co-inventor of the Shutgun, a sprinkler shut off
tool designed for hotel, construction and emergency medical service industries.
“If a sprinkler head is accidentally set off, you can also add water damage to
your list of problems.”
With heat remediation, it would take
approximately 20 minutes heated at 46C to kill adult bugs, and over an hour to
kill their eggs.
“With temperatures reaching above 100 degrees
Fahrenheit, there is concern that the sprinkler heads could potentially be
damaged or set off by such an increase in temperature,” said Eli Scardoni,
former Toronto District Fire Chief.

boxes while the temperature is closely monitored. However, it is wise to always
have a backup plan in place in case the sprinkler is set off by the
