Dangerous moths disposed of
October 1st 2009 Kew Gardens in Richmond is tackling
a dangerous moth problem with the
help of Nilfisk CFM.
The caterpillars of the Oak
Processionary Moth have irritating
hairs that carry a dangerous toxin.
When hairs get blown in the wind
they cause irritation to human and
animal skin, eyes and bronchial tubes,
a particular problem when populations
reach outbreak proportions.
Larvae caterpillars must not be
handled; adults emerge and fly mid
July to early September. Previous
methods of control for this period
focused on insecticides which can be
dangerous in themselves so Nilfisk
worked with experts at Kew to create
an alternative vacuum control system.
The CFM 137 H Class, 110v
vacuum can be taken into the trees on
a cherry picker where a bagging
system allows the moths to be
collected for safe disposal, the bag also
acts as a part filter. The system is
completed with a second stage star
filter (PTFE) and a HEPA filter before
the motor. More articles from Nilfisk -Advance Ltd: |
