Not All Effective Pest Control Looks Like Spray and Pray
The Problem With Traditional Pest Control
Most property owners and managers have experienced the standard
pest control visit: a technician arrives, applies product throughout
the space, and leaves. Two weeks later, the same issues return.
This approach — applying pesticides broadly and repeatedly without
addressing root causes — is both less effective and more disruptive
than it needs to be.
A Restaurant Case Study
A midtown Manhattan restaurant contacted Graduate Pest Control
following a Department of Health inspection that cited rodent
activity and evidence of German cockroach presence. Previous
pest control visits had not resolved the underlying issues.
Our specialists conducted a comprehensive inspection before
any treatment was applied. The findings:
- Three rodent entry points through utility penetrations in the basement — previously unidentified and unsealed
- German cockroach harbourage in dish machine motor housing and behind refrigeration units
- Conducive conditions: a floor drain with inadequate trapping and excessive grease accumulation along the cookline
The IPM Response
Rather than blanket product application, we implemented a
targeted program:
Structural exclusion first. All three rodent entry points
were sealed with appropriate materials. This single step
eliminated the ongoing rodent pressure.
Targeted cockroach treatment. Gel bait applications in
harbourage areas, combined with insect growth regulator
application, addressed the German cockroach population without
disrupting kitchen operations.
Sanitation recommendations. Written recommendations for
the floor drain and cookline grease management were provided
to the client.
The Result
A follow-up DOH inspection found no evidence of pest activity.
The restaurant has maintained compliance for eighteen months
on a quarterly monitoring program.
Effective pest management is diagnostic before it is chemical.
