Do Cold Weather Kill Roaches

Because this can’t always be avoided, it’s important to know how to identify, prevent, and kill roaches in case they do survive the cold winter months. Baby cockroaches look almost nothing like their adult counterparts; instead, their bodies appear white or gray until their exoskeleton begins to harden and gives them their recognizable dark brown or reddish tint.



Considering these young pests are born in groups of 10-20 at a time, spotting a baby cockroach in your home can mean you’re harboring a serious infestation. While their reproductive abilities may falter when temps reach below 45 degrees Fahrenheit, the adult cockroaches can still survive, which can then lead them toward the warm, heated rooms of your home.

While cockroaches can survive in the cold, these pests still prefer heat and humidity, and they are relentless when it comes to finding a way indoors. Because of their uncanny ability to hide within walls, pipes, and small, cluttered corners, it may take months for you to notice a serious cockroach infestation.

Spending time to fill every visible hole and crack in your walls and pipes will help you deter cockroaches from sneaking indoors in droves when the weather cools down. It is still recommended for homeowners to be mindful of the crumbs and residue they leave behind on kitchen countertops and floors, as these are easy targets for roaches searching for food at night.

It’s also important to take out the trash every few days and sweep and vacuum carpets multiple times a week, to remove any cockroach eggs that might be hiding on the surface. If you do find that your home has fallen victim to a cockroach infestation, the most important thing you can do is take action immediately.

Many DIY blogs and articles tout the benefits of using roach bombs and loggers to clear out an infestation, but the effectiveness of this treatment is questionable. These products make your home unusable for hours at a time while the chemicals settle, often coating floors and furniture with the sticky, smelly residue.

Not only are these products not effective at fully killing a roach infestation, but they also require hours of cleanup once the process has been completed. Because this substance is also toxic for humans and animals, homeowners with small children or pets running around may want to avoid using Boris acid within the home.

These pests are notoriously resistant to DIY treatments and can hide in impossibly small crevices throughout your home’s structure, thereby requiring professional extermination solutions. If you do find that the cold weather has brought an influx of roaches into your home, give your local Active Environmental branch a call to schedule an extermination with one of our pest control technicians.

I am thinking about moving out of my home for a month or two…… I want to know that if I leave my home with the windows open, water and gas turned off, cleaned very well, and with the windows open (It has been in the teens at night here), and unplugging everything for about a month or two will that get rid of the roaches. If you read through our ROACH CONTROL ARTICLE, you’ll learn they’re very tolerant of temperature extremes.

Considered cold-blooded”, insects merely go into a state of suspended animation. It’s this state that enables them to endure long periods of time with no food, water or even what we consider to be “warm” temps.

No one really knows for sure but based on observations both afield and in the lab, it’s thought at least one species (the German Roach) can last a year if not longer in this state. If anything, the cold would actually help them endure the same environment longer because it will slow their internal processes.

I also think that freezing the home could present a host of other problems that would prove costly. Birds, squirrels, rats, mice just to name a few would no doubt wander inside.

So during the Summer, when temperatures are soaring and humidity levels are high, they make the most of it and reproduce in large numbers. During the fall, when the air’s a bit dry and the temperature’s dipped to less than 50 degrees, most roach species die off.

You’ll need to take proactive measures by placing roach baits around your property, all year round, to halt their infestation. While these nasty suckers are known as being the most resilient bugs, they also have temperatures that they cannot tolerate.

It is possible to get rid of cockroaches without using chemicals, and one of the ways you can do that is by killing roaches with heat. According to research, they die within an hour when exposed to temperatures below 14 degrees Fahrenheit.

And within thirty minutes when exposed to temperatures below zero degrees Fahrenheit. It is next to impossible to use heat to kill cockroaches as you cannot set your house on fire.

Or you can set items you no longer wish to keep on fire to kill the cockroaches inhabiting them. Well, today we’ll discuss that, and what to do if it turns out that you’re out of luck and find yourself hosting a colony of disgusting ColdWeatherRoaches.

For example, when the temperature drops some species of roaches will actually spend their time huddled together for warmth. In the winter time, when it’s cold outside, many roaches enter a hibernation-like state of dormancy.

This is called disease, an inactive state that slows their metabolism and growth. But, most of this only applies to roaches that spend their lives outdoors.

American cockroaches may feed on anything from human food to feces. Since these roaches prefer areas where food and water are plentiful, they are most often found outdoors.

But once a colony is established, you almost certainly have to contact a pest control specialist. Try to contact a pro that uses green methods of pest control if you can as well since chemical pesticides have often had their safety called into question in recent years.

When the weather starts to cool down, many animals either hibernate or migrate to warmer climates. After all, when your lifespan is anywhere from six months to a year and a half, you don’t have much time for restorative sleeps or road trips.

Read on to learn how seasonal temperature variations can affect the behaviors of two of the most commonly found cockroaches in the United States. These roaches prefer to live outdoors in woodpiles, dead logs and trees; places like that are ideal cockroach habitats for this insect.

But they’d rather stay warm in the fall and winter months, meaning they’re happy to invite themselves into your home. They really enjoy indoor environments that are kept at about 70 degrees, which is likely very close to the temperature you set your thermostat to during the fall and winter.

Not to mention the fact that American cockroaches have been known to settle with family, meaning you may have multiple generations of these bugs in your house at any given time. And they’ll make their ways around many areas, from sink drains to kitchen counters.

Ideal German cockroach habitats maintain a temperature of about 90 degrees Fahrenheit. Even on the iciest day of winter, it’s unlikely that the inside of your home is heated to those high temps.

But that doesn’t matter to the German cockroach, as it prefers to live inside regardless of outdoor temperatures. One reason you may find cockroaches in your house in fall or winter is because of the temperature.

When you start thinking about how to kill cockroaches, the first thing you want to do is figure out ways in which you can make your home less appealing to these insects. Empty vacuum bags away from the house in case they contain cockroach egg sacks.

Eliminate possible water sources by wiping down tubs, shower walls and sinks and by repairing leaky fixtures. If you already have cockroaches in your house, it’s probably best to let a professional pest control service deal with them.

Our trained technicians can work with you to customize a pest control plan that fits your needs. Every house has insects crawling through its foundation, from the smallest termites to the largest cockroaches.

These insects can all be identified based on characteristic shapes, sizes and body coloring. Single queen mounds can number 30-100 per acre with up to 250,000 ants each.
