Cockroaches are among the most resilient and difficult pests to eliminate from a building. The two species most commonly encountered in French-speaking Switzerland are the German cockroach (Blattella germanica) and the Oriental cockroach (Blatta orientalis). Both species are nocturnal, reproduce rapidly, and can develop resistance to commonly used insecticides.
Beyond the obvious unpleasantness, cockroaches represent a genuine public health risk. They carry and transmit a range of bacteria including Salmonella, E. coli and Staphylococcus through their droppings, shed skins and saliva as they move across food preparation surfaces. Their shed skins and droppings also contain allergens that can trigger or worsen asthma and eczema, particularly in children.
For food businesses and restaurants, a cockroach infestation is a critical regulatory issue. Swiss cantonal health authorities take cockroach infestations in food premises very seriously, and businesses face potential closure orders if infestations are not properly managed.
Signs of a Cockroach Infestation
Sightings at night
Cockroaches are primarily nocturnal. Seeing one during the day often indicates a large, established infestation.
Droppings
Small, dark droppings resembling coffee grounds or black pepper, found in kitchen cabinets, behind appliances and in cracks.
Egg capsules (oothecae)
Brown, oval-shaped egg cases, roughly 8–10 mm long, hidden in cracks, behind appliances or glued to surfaces.
Shed skins
Translucent nymphal casings left behind as cockroaches moult through their 6–7 developmental stages.
Musty odour
A distinctive musty, oily smell produced by pheromones and droppings. Stronger infestations produce a very noticeable odour.
Smear marks
Brown smear marks along floor-wall junctions and near cracks where cockroaches shelter.
Our Cockroach Treatment Method
Modern professional cockroach treatment relies primarily on insecticidal gel baits rather than spray applications. Gel baits are far more effective because they are carried back to the harbourage and eaten by other cockroaches, including those that have never come into direct contact with the product. This transfer effect destroys the entire population, including hidden individuals and newly hatched nymphs.
Inspection and harbourage mapping
We inspect all potential harbourages systematically — behind refrigerators and cookers, inside cabinets, under sinks, around pipe penetrations and electrical wiring. Accurately identifying where cockroaches are sheltering is critical for effective bait placement.
Gel bait application
We apply small dots of gel bait in precise locations near harbourages. The gel formulation is highly palatable to cockroaches and contains an active ingredient that spreads through the colony via ingestion and contact. We also use insect growth regulators (IGRs) to prevent surviving nymphs from developing to reproductive adults.
Follow-up and crack-and-crevice treatment
We return for a follow-up visit after 2–3 weeks to assess activity levels and reapply bait where needed. For severe infestations, residual spray application into cracks and crevices may be used as a supplementary measure.
Our cockroach treatments are discreet, minimally disruptive and do not require you to vacate the premises. There is no requirement to bag food or remove belongings before treatment.
