WHAT MATTERS
What to know about american vs german cockroaches
Good pest decisions start with the right identification and an understanding of how the activity fits the property. These are the practical points we consider before recommending treatment or further investigation.
- German cockroaches are small and commonly cluster around kitchens and appliances.
- American cockroaches are much larger and may travel through drains, basements and service infrastructure.
- Correct species identification helps determine where inspection and treatment effort should be concentrated.
Goliath approach
We focus on the source of the activity, the property conditions and a treatment plan that matches the pest rather than relying on generic advice or unnecessary chemical use.

When professional help is useful
Unclear source
When the activity appears in several rooms or shared areas, inspection can help identify how the pest is moving through the property.
Higher-risk areas
Kitchens, commercial sites, roof voids, termite-risk areas and shared buildings often benefit from a structured professional plan.
