COCKROACH EXTERMINATOR – TREATMENT METHOD
Cockroaches can remain hidden in kitchens, bathrooms, cabinets, wall voids and areas around appliances, so visible insects may represent only part of the activity. A professional cockroach exterminator first identifies the species and the main harbourage areas, then builds the cockroach treatment around inspection findings, targeted control, monitoring and follow-up.
This page explains how German, brown-banded, Oriental and American cockroaches differ, how treatment priorities change by species and what to expect from a professional approach. The objective is to control current activity while also reducing food, moisture and harbourage conditions that can support reinfestation.

IDENTIFYING DIFFERENT TYPES OF COCKROACHES
Cockroach species use buildings differently, so correct identification affects where inspection and treatment should focus. German cockroaches are strongly associated with warm, humid indoor areas and are a common indoor species in Quebec, while brown-banded cockroaches can also occupy drier and higher locations. Oriental and American cockroaches may require different inspection priorities because they are often associated with basements, drainage areas or other humid service spaces.
