Application No. 08/483,735
Burgess discloses a device for protecting wooden parts of
buildings against subterranean termites. The device takes the
form of a baited trap, which when actuated by termites,
discharges an insecticide and operates an electrical switch.
According to Burgess, "[t]ypically, said device should be
installed just below ground level near the wooden structure to
be protected against subterranean termites" (col. 1, lines 54-
56). The device comprises a frangible insecticide-containing
capsule 3 attached to the lower side of a top cover 1 and
enclosed by an enclosure including the top cover 1, four side
covers 2 and the combination of a bottom cover 11 and bait
assembly 12. Preferably, the bait assembly extends downward
and outside the enclosure to provide easy accessibility to
subterranean termites. A projectile 6 is held away from the
capsule 3, under the tension of springs 5, by a string release
trigger 7, pin release trigger 10 and alternate release
trigger 9. The bait assembly 12 and the three release
triggers are constructed of cellulose-containing material for
consumption by termites. In the event that subterranean
termites enter the device and consume any of the release
triggers, the projectile 6 is released and propelled by the
