tages over other fumigants. The de-

Insect Fumigant," and points out that
the compound, although deadly to in

as do many insecticides.
Directions for Using.
Para dichlorobenzene is applied in
most instances in the same manner as
ccamphor and naPthalene. 1t is not,
however, necessary to sprinkle it
around in corners or over rugs and
other material. as is often the case
with camphor and naphthalene, but
merely to expose a sufficient quantity
in one or two open or partially open
recePtacles placed over or higher than
the infested cases, goods, and material
which require fumigation.
How Put Up, and Cost.
Observation-Disclosures at the present
time is sold in 5, 10, rs, So and 100
pound and barrel lots, the prices for
which are as follows:
e cents h. in 5. TO- and 25-lb lots.
Is cents per lb. in 50-lb lots.
II Gets per lib. in l00-lb. lots.
- cents per ID. in barrel lots.
1t any considerable quantity is to
be used, it is much better to purchase
OF some wholesale druggist or direct
from the manufacturers.
Applicability to Various Insects.
observation-disclosures is applicable
to many insect pests living under
various conditions and environment
and therefore, requires specific meth
DDS OF application and, unlike carbon
bisulphld, is at the present time used
only indoors and in other places where
ITS Vapors can be closely confined. AS
there is great variation in the ten
aaclty of life among insects. the ex-
istlng conditions should be carefully
noted before a-dichlorobenzene
is applied.
Beetles, such as the rice weevil
granary weevil, the confused -four
beetle. the cadelle, the yellow meal
worm, and few others less common
are particularly hard to kill when in
the adult stage. The larvae of certain
other meal worms are likewise found
by experiment to possess great ten
acity OF life. 1t is therefore recon-
mended that proPortionately larger
amount OF Observation-Disclosures be
used when combating these species,
Moths, flies, reaches, ants. and an
hides are readily killed by para-dich-
torobenZene when used in the ordin-
airy. strength as previously recommen-
ded. y
The action of ara-dichlorobenzen
on insects is primarily upon their
nervous systems. This property is
readily manifested when moth is
exposed to the vaporS for n few sec
ondS. 1t first displays great excite
ment and uneasineSs. followed CLOSELY
by SpaSmodic commissions, and finally
turns over on its back. While in this
position violent nervous and muscu-
lar reflex action is noticed until life
is extinct.
Para dichlorobenze is colorless
crystalline substance which eyaDor-
ateS very quickly as a vapor, if ex-
posed.
1t is not advisable for sensitive per-
sons to remain for a long time in a
closed room where paradichloro-
benzene is freely exposed, as the ordor
may cause annoyance On the other
hand it can be used in closed or oc-
cas1onally opened cupboards and even
IN sitting rooms without causing any
inconvenience whatsoever.
