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 wet, 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.
