How do you find where rodents are entering if the entry points aren't visible?

Our specialists use behavioral evidence — grease marks, travel patterns, droppings, and gnaw points — to trace activity back to its source. We open wall voids, pipe chases, and utility penetrations that standard inspections skip. K9 detection teams help confirm activity in areas that are structurally inaccessible. Entry point mapping is always the foundation before any exclusion work begins.

What materials do you use to seal entry points, and are they permanent?

We seal entry points using galvanized metal mesh as a structural backer, followed by mortar or professional-grade sealants appropriate to the surface. We do not use foam — it compresses, degrades, and rodents chew through it. Our exclusion work is designed to be permanent, though we recommend periodic structural monitoring because buildings shift and new vulnerabilities develop over time.

How long does it take to resolve a rodent problem?

It depends on the extent of entry points, the size of the population, and how long the problem has been active. Most situations see meaningful reduction in pest activity within the first two to three service visits. Full resolution — including completed exclusion work and confirmed absence of activity — typically takes four to eight weeks depending on the complexity of the structure.

Rodent Control in Greenlawn

Greenlawn's pre-1940 Victorian and farmhouse properties, with their original timber framing and field stone foundations, create ideal harborage for rodent populations migrating seasonally from the surrounding wooded areas and creek systems. Graduate Pest Control is a second-generation rodent control specialist serving Long Island and New York City since 1983.

The structural settling and aged construction typical of these homes produce numerous hidden entry points and passages that standard treatment approaches fail to address. Graduate Pest Control provides comprehensive Norway Rat Control and House Mouse Control services that prioritize identifying and sealing these vulnerabilities before pest activity becomes established, rather than responding only after entry has occurred. Graduate's rodent control methodology begins with detailed structural assessment and behavioral analysis specific to your property's construction and seasonal patterns, allowing our technicians to design exclusion and monitoring protocols tailored to Greenlawn's unique environmental conditions and your home's architectural characteristics.
