Some roaches will die off the colder it gets while others will stop breeding or a combination of both. As a home owner or landlord, keeping things cold can help you keep these pests out. The exact temperature you need varies from each species of cockroach, but in many cases keeping it below 70 degrees can help.
Do Cockroaches Like the Cold? Generally, cockroaches don't like the cold one bit. They are cold-blooded arthropods that don't survive very well in either extremely cold or hot circumstances. They're always at whatever temperature their environment is and generally slow down with cooler temperatures.
Cockroaches dislike air-conditioning. They are uncomfortable with cool weather for example, if you set below 25⁰C. They will move to a warmer part of your home. So, keep your home cool!
To answer the question above, roaches don't necessarily die off in the winter. As long as they can find a warm place to shelter with a food source they can survive and reproduce year-round.
No, keeping your house cold doesn't keep bugs out.

Research published in the Journal of Economic Entomology found that some bed bugs survived short exposure to temperatures as low as -13 degrees F. However, if they're exposed to extreme cold (below 0° F) for several days, they will die.
Peppermint oil, cedarwood oil, and cypress oil are essential oils that effectively keep cockroaches at bay. Additionally, these insects hate the smell of crushed bay leaves and steer clear of coffee grounds. If you want to try a natural way to kill them, combine powdered sugar and boric acid.
Leaving the light on doesn't deter cockroaches effectively because they can navigate in low-light conditions. While they're mostly active at night, they may still come out in search of food or water. During the day, cockroaches hide in dark areas not directly exposed to light.
Your Best Bet for Deterring Cockroaches is a Clean Home
Take that away from them and their days are numbered, as long as you maintain it. Cockroaches can live up to three months without food, so they hide in dark corners of a property while they wait to go hunting at night.
Don't: Flush cockroaches down the toilet. Cockroaches can hold their breath for 30 to 40 minutes and will survive being submerged in water. You could be spreading cockroaches, or possibly giving someone an unpleasant toilet surprise. Do: Clean your home completely.
Flies, cockroaches and other pests are attracted to the warmth and food smells of kitchens. In these environments, ceiling fans and air curtains can help keep insects away.
Cockroach season can vary depending on the region. For instance, in Texas and Florida, where the climate is generally warmer and more humid, roaches can be a year-round problem. In other parts of the US, roaches come out during the hottest months, usually from June through September.
Cockroach Behavior
Most don't like it one bit. That's why they tend to scatter when you walk in a room and flick that switch. And it's not just artificial light that cockroaches dislike. They're not fond of natural light either.
American cockroach
Their egg capsules are roughly ⅓” long and are dark reddish or blackish brown in color. Each ootheca holds about 16 eggs.
What smells are cockroaches afraid of? Cockroaches are repelled by the smells of peppermint, eucalyptus, lavender, citronella, and cedarwood oils. These scents can be used as natural deterrents to keep them away from your home.
Seasons come and go, bringing with them a variety of changes. But did you know that these shifts also influence the activity levels of cockroaches? As temperatures drop, roach populations noticeably reduce - it's no secret that cockroaches hate cold temperatures.
Insects and Arachnids
Strangely enough, one of the most prevalent kind of predator that cockroaches face are fellow insects! The emerald cockroach wasp, Ampulex compressa, for example, has an unusual way of preying upon cockroaches. The wasp stings the cockroach's brain, which paralyzes the cockroach.
Pine Sol can kill roaches on contact, though it's not a practical solution for a wide-scale infestation.
Ultrasonic Cockroach Repellents
There are electronic devices that emit high-frequency sound waves that act as cockroach repellents. These devices emit sound in the 22-65 Khz range which is inaudible to humans but can be detected by certain pests, including cockroaches.
Your home provides warmth and shelter that attracts bugs during the cold winter. Keeping your house at a low temperature might attract fewer bugs, but it's an impractical and unnecessary solution to the problem.
