What is the difference?
The terms “cockroach” and “kakerlake” are often used synonymously – and that is basically correct. Both belong to the family of cockroaches (Blattodea). The difference usually lies in the species and habitat.
Cockroaches (e.g., German cockroach, Oriental cockroach) are hygienic pests that prefer to stay in warm, humid indoor areas. They especially thrive in kitchens, pantries, hotels, and food businesses.
These insects are nocturnal, hide during the day in crevices or behind appliances, and can transmit pathogens such as salmonella or mold spores.
Wood cockroaches, on the other hand, are harmless. They live in nature – for example under leaves, stones, or tree bark – and only occasionally wander into apartments. Unlike cockroaches, they do not survive permanently there and do not reproduce.
Difference between cockroach and wood cockroach: The most important features
| Characteristic | Cockroach / German cockroach | Wood cockroach |
| Habitat | Indoors (kitchen, bathroom, basement) | Outdoor areas (leaves, garden, forest) |
| Behavior | active at night, light-shy | active during the day, moves toward light |
| Danger | transmits germs, hygienic pest | harmless |
| Survival indoors | permanently possible | not possible |
| Reproduction indoors | yes, under suitable conditions | usually no |
| Typical locations | Kitchen, pantry, dishwashing area, appliances, cracks | Windows, walls, balcony, terrace, entrance area |
| Appearance | light brown to brown, often with dark longitudinal stripes on the pronotum | usually amber-colored to light brown, often without distinct dark longitudinal stripes |
Tip: If you see a cockroach during the day that actively reacts to light, it is likely a wood cockroach. If it flees and hides in dark crevices, it is more likely a cockroach – and that is a warning sign.
Why cockroaches are dangerous
Cockroaches are considered hygienic pests. They can transmit pathogens, contaminate food, and trigger allergies.
An infestation often remains hidden for a long time. Visible insects during the day can indicate that the infestation is already more severe or that the hiding places are overcrowded. In addition to live cockroaches, droppings, shed skins, egg cases, or an unpleasant odor can also indicate cockroaches.
Common mistakes in cockroach control
A common mistake is incorrect species identification. If a cockroach is mistaken for a wood cockroach, an infestation can spread. If a wood cockroach is mistaken for a cockroach, unnecessary measures are taken.
Removing individual visible cockroaches is not enough. The insects live hidden and often only become visible when the infestation is already more severe.
Unfocused sprays are also problematic. They can scatter cockroaches and make control more difficult. A structured approach with identification, monitoring, hygiene, sealing, and appropriate control measures is more effective.
What helps against wood cockroaches?
With wood cockroaches, prevention is usually the priority. Since they come from outside, possible entry points should be reduced. These include open windows, door gaps, ventilation openings, and cracks.
Insect screens are a simple and effective measure. Outdoor areas directly adjacent to the building should also be kept free of leaves, wood debris, and dense vegetation.
Individual wood cockroaches indoors usually do not need to be treated like a German cockroach infestation. However, correct identification remains crucial.
Effective control with Advion Cockroach Gel
If you have discovered roaches or German cockroaches, quick action is important. Home remedies or sprays rarely help because they only repel the insects – they do not eliminate them.
A targeted, professional method is the use of a bait gel.
We recommend the Advion Cockroach Gel – a highly effective gel with the active ingredient Indoxacarb, specially developed against cockroaches.
Advantages of Advion Cockroach Gel:
- Works directly in the nests: cockroaches take up the gel and carry it into the colony.
- Simple, discreet application – ideal for kitchen, bathroom, basement, and workplace.
- Odorless, long-lasting, and effective even with heavy infestations.
- Suitable for professional and private use.
Application:
- Apply small gel dots (about every 30 cm) along pathways, behind appliances, or in dark hiding spots.
- Places near heat sources (e.g., stove, refrigerator, heater) are especially effective.
- Do not use other insecticides at the same time – this can repel the insects and reduce the bait’s effectiveness.
- The effect appears within a few days, and complete eradication usually takes a few weeks.
Tip: Even after visible success, you should continue to use the gel as a precaution to prevent re-infestation.
Conclusion
Not every cockroach is equally dangerous – but every sighting should be taken seriously. While wood cockroaches are harmless, German cockroaches and roaches can pose health risks.
With the Advion Cockroach Gel, you have a proven professional product at hand that works specifically in hiding places and effectively and sustainably eliminates infestations.
This way, you can quickly restore hygiene, safety, and a good feeling in your rooms.
