Start with what you know
Cockroaches in a flat may use warm appliances, pipe routes and shared service voids. Cleaning helps, but treatment usually fails if the connected route is ignored.
Why this problem happens
German cockroaches often gather near warmth, moisture and food. They can move between flats through service routes. Seeing small cockroaches in daytime may suggest that hidden harbourage is crowded.
What you can do now
- Store food securely and remove cardboard or clutter from warm kitchen areas.
- Dry sinks overnight and repair simple leaks where possible.
- Photograph insects and note the exact room and time seen.
- Keep aerosols away from suspected routes because they can scatter activity and interfere with bait.
What not to do
Do not rely on supermarket spray alone. It may kill exposed insects without reaching harbourage or egg cases, and it can push cockroaches deeper into connected spaces.
When to call a professional
Arrange treatment promptly if you see young cockroaches, find droppings near appliances, or activity appears in several flats or rooms. Coordinated access may be important in shared buildings.
A useful visit should end with a clear explanation of what was found, what was treated, any limits on access, and the next review point. Ask for the total scope and price before authorising work.
Common questions
Are cockroaches caused by poor hygiene?
No. Hygiene affects available food, but cockroaches can arrive in goods or move through connected buildings.
Why are they near the fridge?
The motor area can provide warmth, shelter and nearby moisture.
