The problem
German cockroach is the difficult one — it breeds fast indoors and is the most common reason a treatment has to be repeated.
How you know
Sightings in daylight, which usually means a large population, plus a distinctive musty smell.
What the work involves
Gel baiting with follow-up visits. A single spray treatment rarely clears an established German cockroach population.

The playbook

Cockroach extermination, done properly

Before anyone arrives

Deny them the night: dishes done, sink dry, bins closed, pet bowls up. Note where you saw them — under the fridge, in a cupboard hinge, behind the kettle — because German cockroaches live within a short crawl of warmth and moisture, and those sightings aim the treatment. Resist bug bombs; they scatter roaches deeper into the building and undo baiting.

Do it yourself, or call?

Quality gel baits, placed in cracks near activity rather than sprayed surfaces, can beat a light infestation if you also fix the moisture. Call a professional when you see roaches in daylight, find them in more than one room, or live attached to neighbours — in multi-unit buildings unilateral treatment mostly relocates the problem.

What a proper job looks like

Good roach work is baiting and crack-and-crevice treatment guided by an inspection, with monitors to confirm progress, and follow-up visits scheduled from the start because egg cases hatch after the first treatment. In apartments, a company that asks about adjoining units is one that understands the building, not just the kitchen.

Choosing the company

Roach mentions in reviews mark the companies doing this methodically. The follow-up visit is where cheap jobs fail, so a listing's reply rate and its one- and two-star share across many reviews are the practical signals to read here.
