Pest Control Products for Clean Out
The pesticides used in a German cockroach clean-out will also exterminate
many other pests in homes, restaurants or other businesses.
Basically, the clean-out procedure involves a 3 step operation that targets
large infestations of German
cockroaches with the goal of exterminating or cleaning out the majority of
the roach population at one time. Before beginning this pest elimination
job, make sure that areas are cleaned with no grease or oily residue on surfaces
about to be treated. Inspection and sanitation are the first two steps in
any pest management program.
Leave no foods or utensils out in the open during this procedure. Put away
or cover utensils, food stuffs and food preparation areas.
The first step in a clean-out involves spraying a
residual product that kills roaches as they forage. The second step is
crack and crevice work. This C&C work will kill
roaches where they hide and will flush them out into the open. Once they
have been flushed out, they are more likely to get into your residual
spray. The final step in a cockroach clean-out is to fog
the entire area. This final step is an option as you will see later on.
Now, to the first step.
1) Residual pesticides:
Spraying baseboards, underneath and behind appliances and in other areas where
roaches frequent gives you the long term control that you need. Suggested
products include Cynoff EC, Demon
EC, Cypermethrin 4 ounce or Acephate
Pro PCO. For heavy infestations, use the clean out rate suggested on
the pesticide label. This rate usually uses twice the amount of
concentrated material than that used in maintenance spraying programs.
If you are spraying a restaurant or other commercial
food handling establishment, you must use Acephate
Pro PCO, Tempo SC, or Tempo
2) Crack & crevice work:
When dealing with a severe infestation, a residual pesticide alone will not
exterminate the entire roach population. Using professional aerosols
and/or dusts enables you to inject pesticides into the tiny areas where your
target pests are hiding. This also helps to "flush out" pests,
forcing them to enter areas you have treated with residual products. For flushing action without a residual (for more sensitive areas, food handling
appliances, etc.,) Pyrethrin Aerosols are
3) Once you have finished
spraying your long term insecticide (step 1) and you have done all of your crack
and crevice work (step 2), you might want to fog. This step is not always
necessary. People doing pest control in restaurants, warehouses or rental
property where there is an enormous German cockroach problem prefer to finish
the job by fogging the entire area with a pyrethrin fog material. The
fogging procedure will give a tremendous knock down on all insects or bugs that
have been flushed out into the open.
The first two steps of a clean out agitates the roaches in what we call a
flushing action. Have you ever overheard an uneducated person say that
their pest control technician only "fed" their roaches? They are
reacting to the tremendous increase in roach activity that occurs following a
roach clean out job. Fogging the area will vastly reduce visible roaches
if you have followed the first two steps in a roach clean out procedure.
When fogging indoors, use a cold
fogger instead of a thermal fogger. A cold fog is safer and
cleaner. The most economical material to use in a cold fogger is a pyrethrin
concentrate. (You can also add an ounce or two of pyrethrin
concentrate to your residual pesticide for a quick
knock-down of bugs.)
Only two to four ounces of concentrated pyrethrins is needed to make a gallon of
fogging solution. This is a great deal of material! Only 1 ounce of
solution is needed per 1,000 cubic feet of space to be fogged. More is not
