How to Keep Cockroaches Out of the Kitchen This Winter
Quick Summary / TL;DR
Winter pushes cockroaches toward warm, moist kitchens. Small food + water habits make it easy for them to hide, multiply, and spread quietly.
Why winter spikes
Indoor heat + closed-up homes give roaches stable shelter when outdoor temps drop.
Where they hide
Behind appliances, under sinks, inside low cabinets, pantry corners, and cardboard clutter.
Fast prevention
Wipe crumbs nightly, seal gaps near plumbing, fix leaks, and store food in tight containers.
Pro tip: Focus on “warm + dark + damp” zones first — that’s where winter kitchens quietly feed infestations.
Cold weather tends to push a lot of bugs into hiding, but cockroaches are a different story. In fact, we see more signs of roaches indoors during the winter than at any other time. Warm kitchens become the perfect spot for them to settle in, especially during the cold January stretch. In places with chilly winters like Mount Joy, Pennsylvania, it’s not unusual for cockroach activity to pick up just as we’re spending more time indoors. As a local, family-owned company, we regularly treat winter roach problems in homes throughout Lancaster County and the surrounding communities.
This is where a cockroach exterminator often becomes necessary. Roaches don’t freeze outside if they get in first. They sneak into small spaces, follow pipes, and find places to live without being detected. But once they're in, they multiply quickly. A few missed signs early in the season can turn into a full infestation not long after.
Why Cockroaches Take Over Kitchens in Winter
Kitchens stay warm year-round. Between appliances, cooking, heating systems, and water pipes, the temperature tends to stay comfortable for roaches even when the outdoor air drops below freezing. All that warmth and moisture creates a hiding spot they don’t want to leave.
In neighborhoods across Lancaster County and similar areas, cold weather drives roaches to search for shelter indoors. Once inside, they go straight for places that give them easy access to food and water. Kitchens offer both. Cockroaches are one of the pests we regularly include in our interior winter services, so kitchen activity can be addressed as part of broader home protection.
To make matters worse, cluttered corners and low activity during the winter months make these areas even more appealing. We’re often not pulling out the fridge or deep-cleaning cabinets in January. That quiet makes it easier for roaches to spread unnoticed.
Common Cold-Weather Hiding Spots to Watch For
There are a handful of places inside winter kitchens where cockroaches love to hide. The darker, the better. Moisture helps, but warmth and quiet areas are what really matter. When we check homes in January, we make sure to look carefully around:
- The backs and bottoms of large appliances, like the refrigerator or stove
- Under kitchen sinks near water pipes, especially if there’s a leak or leftover moisture
- Inside lower cabinets that don’t get opened often
- Pantry corners or shelves, especially where boxed goods are stored
- Old cardboard boxes or bags left near walls or on the floor
Most of these hiding places are easy to overlook. They're spots that don’t get cleaned often or aren’t in our regular paths. Roaches know that, and they take full advantage during the quiet weeks after the holidays.
Habits That Invite Cockroaches Into Your Kitchen
Roaches don’t just wander in. They follow signs that food or water is close, and small habits around the kitchen can make a big difference.
A few common things we do without thinking can make it easier for an infestation to grow:
- Leaving food or dirty dishes sitting in the sink overnight
- Letting crumbs build up under toasters, countertop edges, or kitchen rugs
- Keeping pet food in open bags on the floor
- Waiting too long to take out trash or recycling, especially if it's full of food scraps
- Skipping regular wipe-downs around the back corners of counters or floors
Winter makes us want to stay warm and cozy, but it’s also a time when our homes are more closed up and leftovers hang around longer. We’re not airing things out or sweeping behind appliances every day. These little habits can slowly create the perfect welcome sign for roaches.
Small winter habits that quietly invite roaches
Roaches follow food + water signals. These quick swaps reduce the “welcome signs” without a major lifestyle change.
- Dishes or food left overnight in the sink.
- Crumbs under toaster, rugs, and counter edges.
- Pet food stored open on the floor.
- Trash/recycling left full of food scraps.
- Skipping back-corner wipe-downs in winter.
- Nightly 3-minute reset: sink empty + counters wiped.
- Weekly crumb sweep: toaster area + rug edges + baseboards.
- Pet food in sealed bin (off the floor when possible).
- Trash out on schedule; rinse recyclables quickly.
- Monthly pull-out: quick vacuum behind fridge/stove.
Dry the sink area at night + remove food residue. Moisture + crumbs are the combo that keeps kitchens “livable” for roaches.
Practical Prevention Measures That Make a Big Difference
Stopping roaches from settling in usually starts with cleaning, organizing, and sealing the spots where they try to come through. These steps don’t need to be complicated, but sticking with them through winter makes a real impact.
Here are a few things we suggest to keep cockroaches out of your kitchen during the cold months:
- Sweep and vacuum under appliances and cabinets every couple of weeks
- Wipe down counters, including the edges near backsplashes and appliances
- Seal small gaps around doors, windows, cabinets, baseboards, or plumbing lines
- Close off or fix leaking pipes under the sink or in nearby cabinets
- Store food in tightly sealed containers, not open boxes or cracked packages
If cockroaches have already gotten inside, removing the ones you can see doesn't solve the real problem. Roaches lay eggs and travel through hidden cracks. This is where a cockroach exterminator becomes especially helpful. They know how to locate nests, track hidden routes, and treat the areas you can’t easily reach.

Stay Ahead of Winter Infestations with Smart Habits
Roaches don’t care if it’s January. All they need is a warm, quiet spot with a little food and water. Our kitchens give them a cozy place to wait out the cold, and before long, that small problem can become a serious one.
We may not think about pest control during the middle of winter, but that’s when prevention matters most. Keeping the kitchen clean, sealed, and free of little invitations goes a long way. A few small habits now can help keep things quiet when spring arrives. When the temperature outside drops, our attention inside is what makes the difference.
Unwanted roaches in your kitchen need action to prevent them from spreading. We inspect hard-to-see hiding spots, follow their tracks through walls and pipes, and spot signs many overlook. A small issue left unchecked means they have settled in longer than expected. If you're noticing these signs, it might be time for a
cockroach exterminator. Keystone Pest Solutions is here to help,
give us a call and we'll take care of it.
Winter Kitchen Roach Prevention Checklist
These are the highest-impact habits for keeping roaches from settling in and multiplying during cold months.
Clean Remove food signals
Dry Reduce moisture
Seal Block entry & hiding
When DIY isn’t enough: If you’re seeing repeat activity, eggs/nests may be in hidden voids. That’s where a professional inspection and targeted treatment plan helps most.
Why do roaches show up more in winter kitchens?
Kitchens stay warm and often moist around pipes and appliances. Cold weather outside pushes roaches toward stable indoor shelter.
What are the first signs I should watch for?
Activity is often near sinks and appliances: nighttime sightings, small dark specks, or a persistent “musty” odor in low cabinets or corners.
When should I call a cockroach exterminator?
If sightings repeat, activity spreads beyond one area, or you suspect hidden nesting routes through walls and plumbing lines, it’s time to bring in a pro.
