Rodenticides: A Tool, Not the Strategy
Understanding Rodenticides
Rodenticides are effective tools for reducing rodent populations.
They are not, however, a long-term solution when used without
a broader Integrated Pest Management strategy.
In New York City and Long Island, rodent pressure is persistent.
Properties that rely exclusively on bait station maintenance
without addressing entry points and harbourage tend to face
ongoing challenges regardless of product efficacy.
The Environmental Impact of SGARs
Second-generation anticoagulant rodenticides (SGARs) present
documented risks to non-target wildlife. Raptors, owls, and
foxes that consume poisoned rodents accumulate these compounds
in their systems. New York State has increasingly scrutinized
SGAR use in response to these concerns.
Graduate Pest Control uses SGARs only when warranted by
population pressure and in configurations that minimize
non-target exposure. First-generation anticoagulants and
non-anticoagulant alternatives are preferred where appropriate.
What an IPM Rodent Program Looks Like
A science-based rodent program begins with inspection and
ends with exclusion. The sequence matters:
- Identify entry points — every gap, penetration, and structural deficiency that permits rodent access
- Map harbourage — where are they living, nesting, traveling
- Seal entry points — this is the most important step and the one most often skipped
- Reduce harbourage — sanitation and structural recommendations
- Apply targeted population control — rodenticides or mechanical trapping as appropriate
- Monitor and adjust — ongoing surveillance ensures the program is working
Rodenticides accelerate population reduction. Exclusion prevents
reinfestation. Neither works well without the other.
