Before you call

What to know about cockroaches

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.
