Turning ?rst to FIG. 1 of the drawing, a metal strip

metal of su?icient size to permit the housing of the entire 65
cylinder. In order to prevent the cylinder from slipping,
a metal strip 12 has been brazed or welded across the
diameter of the metal ring 8.
however, the bottom end of the cartridge has one or more
holes so that during the cold season, twice as much area
will be available for the insecticide to ?ow, whereas in
the warm season only one hole will be used. This pref
erence is based on the fact that the insecticide during the
cold season has a high viscosity and the ?ow will be
somewhat impeded.
In order to permit the insecticide cartridge to be port
able without danger of leaking, these holes have been
covered by a blister-like covering 10, which may be of
