Cockroaches
Blattodea
Cockroaches are insects that carry bacteria and trigger allergies. They hide in warm, humid places, then contaminate food and kitchenware.
Common cockroaches in Indonesia
German Cockroach (Blattella germanica)
The most common small cockroach in kitchens and F&B areas. The fastest breeder and the hardest to remove without baiting.
American Cockroach (Periplaneta americana)
A large cockroach of drains and sewers; often enters from outside through floor drains.
Signs of Cockroaches
- Small pepper-like droppings in kitchen corners.
- A musty odour in infested areas.
- Roaches seen when lights turn on at night.
Why Cockroaches are dangerous
Cockroaches carry bacteria like Salmonella and E. coli that cause diarrhoea, food poisoning, and typhoid. Their droppings and body fragments are also allergens that trigger asthma, especially in children.
Cockroaches behaviour & life cycle
Cockroaches are nocturnal and hide in warm crevices near water and food. They breed extremely fast — a single ootheca (egg capsule) holds dozens of eggs, and roaches can survive weeks without food. Spreading through drains and carried goods, even a clean home can still become infested.
How to prevent Cockroaches
- Clean crumbs and dry sinks at night.
- Cover drains and seal kitchen cabinet gaps.
- Store food tightly and manage waste well.
Frequently asked questions
Why are there cockroaches even in a clean home?
Cockroaches enter from drains and building gaps, then hide in hard-to-reach spots. Gel baiting control targets the whole population.
Can cockroaches fly?
Some species like the American cockroach can glide or fly short distances, especially in hot weather. This helps them move between rooms and buildings.
Why don't ordinary sprays finish off cockroaches?
Sprays only kill visible roaches, not the eggs and hidden colony. Targeted gel baiting is carried back to the nest, breaking the life cycle down to the eggs.
