Application No. 08/300,089
application.
The claimed invention is directed to a method for
exterminating insect pests wherein the pests are hidden behind
a laser permeable solid barrier. In one embodiment, the laser
is projected directly through the solid barrier. In another
embodiment, a hole is made in the solid barrier and a laser
delivery device is inserted in the hole so that laser light
can be introduced directly into a space behind the barrier
where the pests are present.
Claim 14, reproduced below, is further illustrative of
the claimed subject matter.
14. A method for exterminating pests hidden behind or
within a laser-permeable solid barrier, which comprises
scanning the barrier with a laser beam, thereby bathing the
barrier with laser light having a power and wavelength
sufficient to pass through the barrier without substantially
damaging the barrier and sufficient to exterminate a pest
hidden behind or within the barrier.
