Rodent Proofing
Preventive protection for vulnerable areas.
Prevention is mostly about food, shelter and access.
Short answerPrevention means taking away what rodents need: food, water, shelter and ways in. Seal garbage, clear clutter, close gaps and inspect often. Prevention lowers the odds but does not remove rodents already inside.
Use hard containers with tight lids, put garbage out close to pickup time and store food in sealed containers. Food businesses should manage waste and deliveries carefully.
Move boxes and stored materials off floors and away from walls. Trim planting near buildings.
Inspect doors, vents, pipe openings and foundations regularly. See rodent proofing.
Note signs early and report them. If you rent, tell the owner in writing.
Not sure what you are dealing with? An inspection finds the source and sets the scope.
Food, water, shelter and safe ways to move around. In practice that means garbage that is not in sealed containers, clutter and stored materials against walls, overgrown planting, and cracks or holes in foundations, sidewalks and doors. Removing those conditions makes a property less attractive, but rats already present still need to be dealt with.
Store food, pet food and dry goods in sealed hard containers. Keep garbage in sealed bins and take it out close to pickup time. Clear clutter and boxes off floors and away from walls. Note where you see droppings, gnaw marks or hear noise, and photograph them. Avoid blocking runways or sealing holes you have not inspected, because that can trap animals inside.
Rodents are active all year in New York. Many people notice more indoor activity as temperatures drop, because animals look for warmth, food and shelter inside buildings. Warm months bring more rat activity outdoors, with garbage and outdoor dining in the mix. Treat the season as context, not as a reason to wait on an inspection.

Finding and closing the openings rodents use.
Activity that keeps coming back usually means the source or the entry route is still open. More traps do not fix that. An inspection looks for where they are getting in and what is drawing them.
