COCKROACH

Cockroach control involves reducing food and water, checking cracks and monitoring hiding places. Choose a surface treatment suited to the pest. An insect repellent or plug-in liquid for mosquitoes is not a substitute.

WHY DOES IT MATTER FOR HEALTH?

Cockroach droppings, body fragments and secretions can contain allergens that trigger allergy and asthma symptoms in susceptible people. Movement between waste and food areas also matters for hygiene and contamination. Manage hiding places, food and water together without assuming every encounter causes illness.

Yes. Cockroaches can reach clean homes through belongings, packaging or routes within a building. Food, water and sheltered gaps help them establish themselves. Blaming cleanliness alone can overlook entry points and sources around the building.

Kitchens, bathrooms, pipe openings, cupboard joints and warm, narrow gaps can provide shelter. Many species are active mainly at night. Looking only in open areas may miss hidden cockroaches.

Why do water sources matter?

Leaking pipes, damp areas and water left accessible overnight can support cockroaches. Fix leaks, cover food and reduce narrow hiding places together. One measure does not replace the others.

Is dealing with one visible cockroach enough?

Unseen cockroaches and immature stages may remain in hiding places. One sighting does not reveal the full extent. For recurring or widespread problems, combine monitoring and competent pest-control support to assess sources and shelter.

HOW DO YOU CHOOSE THE RIGHT PRODUCT?

  1. 01

    Check the target pest

    Check that the label specifically lists cockroaches. A general reference to pests does not establish suitability for this target.

  2. 02

    Identify the application area

    For this target, choose only surfaces permitted by the label. Do not treat people, animals, food or textiles that directly contact the skin as application areas.

  3. 03

    Read the application method and any stated duration

    Compare the target-specific application method and any stated duration. Do not transfer instructions between products or assume unverified durations.

  4. 04

    Check the authorisation details

    Especially when buying online, check the biocidal authorisation number and date, active ingredient and instructions on the back label.
