Cockroaches:
In badly infested apartments, tests have shown that more cock-
roaches were killed with the Sierra than were killed with a py-
rethrum fog. Cockroaches can instantly retreat into crack and
crevices or their lair where air currents do not deliver the fog. The
vacuum can pull them out along with the egg capsules, which are
not affected by the fog.
There are many advantages to removing the dead cockroaches.
Many studies have shown a serious problem with asthma exists in
low-income housing, caused by particulate from cockroach car-
casses.
There are alternatives to pesticides that can flush out cockroaches
so they can be picked up with the vacuum. These include hot air
from a hair dryer, a plain air aerosol can or air from a compressed
air sprayer. The Sierra must be ready to capture the cockroaches
when they flee their hiding places.
The initial and annual treatment should include the use of the
"down and under" long crevice tool to remove food particles, egg
cases, dead roaches, etc., in hard to reach areas under and behind
machinery. Doing this will make the bait more enticing.
A few cockroaches could survive the bumpy ride down the hose.
To keep them from escaping, leave the motor running when clos-
ing and removing the bag. Place the paper bag in a plastic bag
and seal it before discarding it.
Periodic removal of organic debris under and behind equipment
and appliances can easily be made with the Sierra "down and
under" long crevice tool. This accumulation of debris is rich with
allergens and roach-attracting body odors, inviting more roaches
to the site. Particles of this allergen saturated detritus become
airborne and contaminate the indoor air. Recycled in the air, these
particles can be life threatening to thousands of asthmatics. A
High-filtration Disc in the dome filter of the Sierra filters out over
99% of potentially harmful particulate in the air we breath.
