The weather is getting cooler, which most of the time means fewer pests. But there are exceptions, and one exception that we’re seeing very often is the presence of rats.
As temperatures drop in Staten Island, rats start looking for warm, sheltered places to nest – and unfortunately, your home or business can be exactly what they’re looking for. Cooler weather drives rats indoors, and once they’ve found their way in, they can cause significant damage, spread disease, and reproduce quickly enough to turn a small problem into a major infestation.
Rat season typically peaks in fall and winter, which means now is the time to start monitoring your property for signs of rat activity. The earlier you catch an infestation, the easier and less expensive it is to address. Waiting until you see rats running across your kitchen floor means the problem has likely been building for weeks or months.
At Fillmore Termite and Pest Control, we help Staten Island homeowners and business owners identify, prevent, and eliminate rat infestations before they get out of control.
Why Rat Season Happens in Fall and Winter
Rats are active year-round, but their behavior changes with the seasons. During warmer months, rats can find food, water, and shelter outdoors relatively easily. They nest in gardens, woodpiles, garbage areas, and overgrown vegetation.
But as temperatures drop, outdoor food sources become scarce, and rats start seeking warmth and shelter. They’re drawn to buildings – homes, restaurants, warehouses, apartment buildings – where they can find consistent warmth, access to food, and safe places to nest.
Staten Island’s urban and suburban environment provides plenty of opportunities for rats. Older homes with gaps in foundations, commercial buildings with dumpsters and loading docks, and properties near parks or waterfront areas are all at higher risk during rat season.
The problem compounds because rats reproduce quickly. A single pair of rats can produce dozens of offspring in a year, and those offspring reach reproductive maturity in just a few months. What starts as one or two rats finding their way into your basement can become a full-blown infestation within weeks.
Signs of Rat Activity to Monitor For
Rats are nocturnal and tend to avoid humans, which means you might have a rat problem for weeks before you actually see one. That’s why monitoring for signs of rat activity is so important – you want to catch the problem before it becomes obvious.
Here’s what to look for:
Droppings
Rat droppings are one of the most common and reliable signs of activity. Fresh droppings are dark, moist, and shiny, while older droppings are dry and grayish. Norway rats (the most common species in Staten Island) leave droppings that are about ¾ inch long, blunt at both ends, and shaped like capsules.
Check areas where rats are likely to travel or nest: along baseboards, in cabinets, under sinks, in attics, basements, crawl spaces, and near food storage areas. If you find droppings, note how many there are and whether they appear fresh – this gives you a sense of how active the infestation is.
Gnaw Marks
Rats need to constantly gnaw to keep their teeth from growing too long, which means they’ll chew on just about anything – wood, plastic, electrical wiring, cardboard, and even metal pipes.
Look for gnaw marks on baseboards, door frames, food packaging, electrical cables, and structural wood. Fresh gnaw marks appear lighter in color (the exposed wood or material hasn’t darkened yet), while older marks are darker. If you’re seeing fresh gnaw marks, rats are actively present.
Grease Marks and Rub Marks
As rats travel along walls and through tight spaces, the oils in their fur leave dark, greasy smudge marks on surfaces. These marks, called “rub marks,” appear along baseboards, walls, beams, and pipes where rats repeatedly travel the same routes.
Check areas near walls and corners, especially in basements, attics, and behind appliances. If you see dark streaks or smudges at about floor level, rats may be using that path regularly.
Tracks and Footprints
In dusty or dirty areas, you may be able to see rat tracks or tail drag marks. Rats have small feet with distinct toe prints, and their tails often leave a thin line between footprints.
To test for rat activity, you can sprinkle a thin layer of flour or talcum powder in areas where you suspect rats are traveling (like along baseboards or near suspected entry points). Check the area the next morning for tracks.
Nesting Materials
Rats build nests out of shredded materials like paper, fabric, insulation, cardboard, and dried plant matter. These nests are typically hidden in dark, undisturbed areas like wall voids, attics, basements, behind appliances, or inside stored boxes.
If you notice shredded materials in unusual places, or if you find a concentrated pile of soft, shredded debris, you may have found a rat nest or nesting site.
Sounds
Rats are most active at night, and if you listen carefully, you may hear them moving around. Common sounds include scratching, scurrying, squeaking, or gnawing noises coming from walls, ceilings, attics, or crawl spaces.
If you consistently hear these sounds at night, especially in the same area, it’s a strong indicator of rat activity.
Burrows and Entry Points
Norway rats often burrow into soil near foundations, under porches, or along the edges of buildings. Look for fresh dirt mounds, holes about 2-4 inches in diameter, or disturbed soil near your home’s foundation.
Also inspect the exterior of your building for potential entry points. Rats can squeeze through openings as small as a quarter. Check for gaps around pipes, vents, utility lines, damaged screens, cracks in foundations, and gaps under doors.
Unusual Pet Behavior
If you have dogs or cats, pay attention to their behavior. Pets can often detect rats before you see any other signs. If your dog is suddenly fixated on a particular wall, baseboard, or area of the house, or if your cat is behaving unusually alert or agitated, it’s worth investigating.
What to Do If You Find Signs of Rats
If you’ve identified any of these signs, don’t wait to take action. Rat infestations grow quickly, and the longer you wait, the more difficult and expensive the problem becomes to solve. That is why you should do the following:
Contact a Professional Pest Control Company
Rats are difficult to eliminate on your own. Over-the-counter traps and poisons can help with very minor issues, but if you’re seeing multiple signs of activity, you need professional help. Fillmore Termite and Pest Control has the experience, tools, and knowledge to identify the extent of the infestation, locate entry points, and implement a comprehensive treatment plan.
Don’t Just Treat the Symptoms
Setting a few traps might catch a couple of rats, but if you don’t address the entry points and conditions that attracted them in the first place, more rats will keep coming. Professional pest control includes exclusion work – sealing entry points so rats can’t get back in – and sanitation recommendations to make your property less attractive to rodents.
Act Quickly
Rats reproduce rapidly. What seems like a small problem now can become a major infestation in a matter of weeks. Early intervention saves time, money, and stress.
Protect Your Home This Rat Season
Rat season is here, and the cooler weather means rats are actively looking for warm places to shelter. By monitoring your property for signs of activity and acting quickly when you find evidence of rats, you can protect your home or business from the damage, health risks, and stress of a rat infestation.
If you’ve noticed any signs of rat activity, or if you want to schedule a preventive inspection, contact Fillmore Termite and Pest Control today. We serve Staten Island and the surrounding areas, and we’re here to help you keep your property rat-free.
