Cockroach
Baits
- New
baits are expensive but very effective -
|
Summary: New cockroach baits
can be very effective in multi-family dwellings,
food handling facilities, commercial buildings
and/or situations where sanitation and water sources
can not be controlled. Baits combine a highly
attractive food with a low toxicity insecticide.

Use
baits instead of sprays for roaches
Sometimes
sanitation and water source elimination alone
are not enough to control a stubborn cockroach
infestation and you have to bring out the "big
guns". In this case the big guns are baits
not insecticidal sprays. Sprays tend to
disperse roaches because these insects can detect
and avoid low concentrations of insecticide residue.
Plus, baits can be formulated so that when roaches
feed on a bait and return to their hiding places
they contaminate other roaches (see What
are Cockroaches?).
Inexpensive
bait products that are available from lawn and
garden stores and similar retail outlets are only
marginally effective even for light infestations in
single-family dwellings. For difficult infestations
in multi-family dwellings or commercial
buildings you'll need the baits that
professional exterminators use (see the list below).

Advance
Gel Bait (pdf)
- contains a new active ingredient
that is less likely to be affected by
pesticide resistance.
|
|
Advion
Gel Bait (pdf)
- contains one of the newest active
ingredients and is less likely to be
affected by pesticide resistance.
|
|
Avert
Dry Flowable (pdf)
- is the only dry flowable bait. Dry baits
last longer than gel baits and can be
"dusted" into areas that are not accessible to
gels.
|
|
Maxforce
Magnum (pdf)
- needs a separate applicator "gun" to apply
so is generally more expensive on a
per application basis than other baits.

Water
resistant baits for outdoor use
Most
baits are formulated to be used indoors where
it is dry. However, in warm, humid climates such as
the southeastern US cockroach baiting is frequently
deployed outdoors around the foundation of
homes and buildings. You'll need a weather-resistant
bait for this application. Niban Granular Bait (pdf) can be used outdoors for a
variety of pests including cockroaches.

Using
roach baits correctly
It
makes no sense to use these relatively expensive
products incorrectly. If you keep in mind the
following suggestions the baits will work better and
in the long run you'll use less of them. Use
baits only in situations where less expensive
methods don't seem to be working. For example,
in most cases you should start by eliminating
sources of food and water, applying borate
dust behind equipment and cabinets, and treating
cracks and crevices with a residual insecticide.
These
steps alone, however, may not always be enough for
some infestations and you'll need to deploy baits.
Baits should never be the only approach,
however. Don't place baits on surfaces where
pesticides have been recently applied because
pesticide residue may interfere with bait acceptance.
Finally, place baits exactly as directed by product
instructions and replace as necessary.
