Turning ?rst to FIG. 1 of the drawing, a metal strip
or angle iron 7 has been welded to two metal rings 8 and
9. These rings 8 and 9 are made out of heavy gauge
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

it should be understood that the above description is -
meant for purposes of describing and illustrating the in

What we claim is:
1. In combination, an insecticide applicator comprised
of the other end, a sealed insecticide cartridge for in
sertion into said hollow cylinder and having means for
unse‘aling said cartridge when inserted, said cartridge hav
ing an enlarged portion at its outer endcooperating with
the adjacent absorbent material inside said hollow cyl

4. An insecticide applicator comprised of a hollow cyl
inder having absorptive material ‘about its outer surface
and one end portion of its upper surface, wire mesh
wrapped around said outer absorptive material, weep
holes located about the surface of said hollow cylinder,
a sealed container insertable into said hollow cylinder,
