POINTS TO CONSIDER IN CONTROLLING
COCKROACHES

* Why Control Cockroaches
Cockroaches are pests throughout the United States. They are
annoying and when abundant they are also destructive. These
insects, also known as waterbugs, croton bugs or palmetto bugs,
destroy food and damage fabrics, bookbindings and other ma-
terials. When cockroaches run over food they leave filth and
may spread disease germs. They secrete an oily liquid from
their scent glands that is offensive and sickening. This odor may
ruin food and be imparted to dishes that are apparently clean.
Excrement in the form of pellets or an ink-like liquid also con-
tributes to this nauseating odor.

velop. Learn Where They Live, Crawl or Hide

BROWN AND AUSTRALIAN. BOTTOM: (LEFT TO RIGHT): GERMAN
AND BROWN-BANDED.








Kinds of Cockroaches.-The kinds of cockroaches most com-
monly found in and around Florida homes are shown in Figure 1.
The smallest cockroaches, the German and the brown-banded, are
close to the same size and the adults are seldom more than %"
long. The larger cockroaches, the American, Australian, brown,
and the smoky brown are 11/2" to 2" long. Though they are
generally found outdoors they can become an indoor problem
when they migrate or are carried indoors. The largest cockroach,
the Florida woods roach, will also enter dwellings from the out-
side or from beneath the house.
Development of the Cockroach.-The cockroach has three life
stages: the egg, nymph and adult. Cockroach eggs are deposited
in groups in a leathery case or capsule called an ootheca. This
capsule is usually dropped or glued to some surface by the female
as soon as it is formed, however, the female German cockroach
carries the capsule protruding from her body until the eggs are
ready to hatch. There may be from 30 to 48 eggs in the capsule
of the German cockroach but capsules of other cockroaches may
have only 10 to 28 eggs.
The newly hatched nymphs have no wings and they shed their
skins, or molt, several times before becoming winged adults.
Figure 2 shows the developmental stages of the German cock-
roach.
German and brown-banded cockroaches may have several
generations per year but others may require a year to develop
from egg to adult.

















FIGURE 2.-LIFE CYCLE OF THE GERMAN COCKROACH. ADULT
FEMALE AND MALE, NYMPHS AND EGG CAPSULE.








Where to Look for Cockroaches-Cockroaches hide in dark,
sheltered places during the day and come out and feed at night.
They may be found around the kitchen sink or drainboard; in
cracks around or underneath cupboards and cabinets or inside
them, especially in the upper corners; behind drawers; around
pipes or conduits, where they pass along the wall or go through
it; behind windows or door frames; behind loose baseboards or
molding strips; on the under side of tables and chairs; in the
bathroom; and in radio and TV cabinets.
The German cockroach is usually found in the kitchen and
bathroom, while the brown-banded roach may be found all over
the house. Look for brown-banded cockroaches in the upper part
of cabinets or closets and bookcases, behind mirrors, in drawers
or behind pictures and clocks, in radio and TV cabinets and other
similar places.
Other kinds of cockroaches prefer damp, warm places and
usually develop in basements, storerooms and similar locations.


Make It Difficult For Cockroaches to Become Estab-
lished
Prevent infestations.-Inspect all baskets, bags or boxes of
food, firewood and laundry brought into the house. Destroy any
cockroaches or egg capsules that are found. Make it difficult for
cockroaches to enter by filling with patching plaster, putty or
plastic wood all openings around pipes passing through floors or
walls, as well as cracks leading to spaces behind baseboards and
doorframes, particularly if cockroaches are coming in from ad-
joining apartments or from outside. Keep door and window
screens in good repair and make sure that there are no cracks
between them and the frames.

Sanitation Is Very Important
Sanitation or cleanup will aid considerably in cockroach con-
trol. Take away their food supply. Store food in tight containers
and avoid spilling flour, cereals and other dry materials in cup-
boards or on pantry shelves. Do not leave remnants of food on
tables or in kitchen sinks overnight. Sweep up any crumbs or
bits of food from the floors of kitchen, pantry and dining areas.
Put table scraps, vegetable parings and other waste materials in
tightly covered garbage cans.









* Know What Insecticides to Use. The Manner of Ap-
plication Is As Important As What to Use
What to use.-Sprays and dusts properly applied will control
cockroaches. German cockroaches, however, are often resistant
to chlordane, dieldrin, lindane and malathion. Baygon, diazinon
and ronnel (Korlan) will control resistant cockroaches.
Sprays and dusts can be purchased ready-prepared, however,
sprays can be prepared according to directions on the label. Be
sure sprays mixed with water are used the same day otherwise
they will lose their effectiveness.
Baits are currently available but are not as fast acting as
sprays or dusts. When dealing with heavy infestations baits
should not be expected to control cockroaches, however, they can
be used in addition to residual sprays. At present, a bait con-
taining Kepone would be the most effective for a homeowner to
use.
(1) Baygon.-Commercially prepared 1% oil solution; con-
trols German cockroaches as well as other kinds.
(2) Chlordane-2% oil solution or water emulsion; or 5%
dust-German cockroaches have developed resistance; controls
other kinds.
(3) Diazinon.-O.5% oil solution or water emulsion; or 1%
dust-controls German cockroaches as well as other kinds.
(4) Dieldrin.-0.5% oil solution or water emulsion; or 1%
dust-German cockroaches have developed resistance; controls
other kinds.
(5) Lindane.-0.5% oil solution or water emulsion; or 1%
dust-German cockroaches have developed resistance; controls
other kinds, but duration of effectiveness is shorter than that of
chlordane and dieldrin.
(6) Malathion.-2 to 3% oil solution or water emulsion; or
5% dust; controls German cockroaches as well as other kinds,
however, German cockroaches have shown resistance in some
areas.
(7) Ronnel (Korlan).-2% oil solution or water emulsion-
controls German cockroaches as well as other kinds.
Application of insecticides.-Be sure you understand where to
look for cockroaches before applying insecticides. Sprays are
generally more suitable than dusts and do not leave visible re-
sidues. Liquids may be applied with any of the applicators shown
in Figure 3 or a more expensive compressed air sprayer similar
to the one shown in Figure 4.




























FIGURE 3.-SOME TYPES OF HOUSEHOLD APPLICATORS. PAINT
BRUSH, COMMON BOTTLE TYPE, PUFF DUSTER, AND PUMP OIL
CANS (COURTESY OF FRANK MEAD, DIVISION OF PLANT INDUS-
TRY, FLORIDA DEPARTMENT OF AGRICULTURE).
Apply sprays along baseboards, back of the stove and refrig-
erator, around pipes and under sinks, on exposed surfaces where
roaches crawl, on the under side of objects and other places
where cockroaches may crawl or hide. Hold sprayers about 6
inches from the surface being treated and apply a fairly coarse
spray so that the surface will be wet, but so that it does not form
droplets and puddles on the floor.
A paint brush is excellent for applying liquid insecticides to
baseboards, the inside of cabinets, the bottom and outside of
drawers and similar locations. Remove drawers before treating
thoroughly the inside of cabinets, desks and similar furniture.
Allow time for cabinet shelves and drawers to dry and then re-
place shelf paper before replacing contents of shelves and
drawers.
A small duster similar to the one shown in Figure 3 is excellent
for applying dusts to the edges of baseboards, in corners, in and
around cupboards and similar hard-to-reach places.
Cockroach control outdoors.-To reduce the number of cock-
roaches going indoors, it is suggested that dusts containing 5 or
10% chlordane, or 1 to 2% diazinon or dieldrin be applied under
the house, porches, etc. and to mulches in and around flower
beds, shrubs, etc. If the house is on a concrete slab, a barrier can






























FIGURE 4.-ONE GALLON COMPRESSED AIR SPRAYER.
be made by applying the dust in a band 1 or 2 feet wide on the
ground around the house. Other outside places where cock-
roaches are commonly found should also be treated. If sprays
are applied, use those to be mixed in water and applied to plants
(not household spray mixtures containing oil). Follow mixing
directions on the manufacturer's label.
Commercial products and services.-Ready-prepared sprays
containing one or more recommended insecticides and equipment
for applying them are available in local stores. They are sold
under various trade names with the active ingredient given on
the label. Read the label to make certain that you get the chem-
ical you want in the amount you need.
The Structural Pest Control Industry offers professional ser-
vices in the control of cockroaches and other household pests.
Florida law requires these businesses to be certified and licensed
to perform these services. They have the equipment and training
to do a thorough job, therefore, many people prefer to use this
service rather than try to control these pests.

* Be Thorough Practice Pesticide Safety
Avoid contaminating food, water, cooking utensils and dishes
with cockroach-control chemicals. Cover exposed food or cook-








ing and eating utensils in a room that is being treated to protect
them from spray. Remove fish bowls, pets, etc. from the room
or protect them while insecticides are being applied. Have ade-
quate ventilation in rooms being treated. If the insecticide is
spilled on the skin, wash immediately with soap and water.
Oil solutions should not be used near an open flame. Oil solu-
tions that get on asphalt tile floors should be removed immedi-
ately, as they will damage them. Store insecticides out of reach
of children, pets and irresponsible persons. Do not store cock-
roach-control chemicals where they may be mistaken for a food
product or medicine. Dispose of empty containers promptly and
safely.
