German cockroach kitchens
Best roach bait
The best roach bait is a slow bait placed where German cockroaches already hide: hinges, cabinet corners, the motor well of a refrigerator. A smear on an open baseboard is wasted, and a fogger on top of gel scatters the population. Identify the cockroach in How to get rid of cockroaches first. American and oriental cockroaches are a sewer and moisture job, not the same dots.

Which one to buy
Labeled product
Combat Max cockroach gel bait (syringe)
Best overall gel — Many small dots, not a bead. Combat Max is the consumer gel in this catalog. Keep it out of food contact and off surfaces you wipe every day.
Labeled product
Advion cockroach gel bait
Best rotation gel — Indoxacarb is a different class from fipronil gels. Operators rotate for that reason. Pea-sized placements in voids. The label still decides food-area rules.
Labeled product
Hot Shot Ultra liquid roach bait
Best liquid station — Roaches need water. A liquid station helps in a dry, air-conditioned kitchen. Do not park a repellent spray beside it.
Labeled product
Harris boric acid roach tablets
Best dry bait for voids — Boric acid tablets for out-of-reach voids. They are not the first tool in a German kitchen, and they are a poison. Keep children and pets out.
Labeled product
Cockroach insect growth regulator discs
Best add-on, not a bait — An insect growth regulator does not replace gel. It sits beside a bait program. Read {best:cockroach-igr}.
Where the bait has to go
German cockroaches aggregate in cracks with food, water, and warmth. The dots belong in those cracks: the hinge of the under-sink door, the gap beside the dishwasher, the rear corners of a pantry shelf you do not wipe. A dozen dots the size of a pea beat one line along a toe-kick that the mop removes.
Sanitation decides whether they eat the bait. Grease and open trash are a better restaurant. Wipe the competing food. Do not wipe the dots. Monitors (Best cockroach traps) tell you if the next cabinet is still producing nymphs.
What ruins a bait job
- A total-release fogger. It misses harborages and flushes roaches into new rooms.
- A repellent spray on the same crack as the gel. Roaches stop feeding.
- Bait in the middle of a counter where you prepare food.
- One station for a whole apartment stack. Neighbors reseed your kitchen.
Common questions
What is the best roach bait for a bad infestation?
Gel in many harborages, plus sanitation, plus monitors. Add an IGR if nymphs keep appearing. A fogger is not the upgrade.
Gel or bait stations?
Gel reaches the crack a station cannot. Stations and liquid baits help in dry, open placements. Use gel first in a German kitchen.
How long until bait works?
You should see fewer adults in days if the dots are in the harborage and nothing repellent is beside them. A building-wide population takes longer because the adjacent unit is untreated.
