Main reasons for crickets to die is low temperature and shortage of food and water. Crickets die when temperature drops below 18°F (-8°C) for 24 hours or longer. Crickets usually die during fall season before winter starts. Temperature above 90°F (32°C) will increase cricket’s metabolism which will result in speed up lifecycle and faster death. Without food crickets will die within few weeks due to lack of nutritious food and water. Crickets can also die faster when humidity is above 50% and big concentration of crickets can result in deadly diseases.
At What Temperature Do Crickets Die?
How much cold can a cricket take? Crickets usually die when temperature drops below 18°F (-8°C) for 24 hours or longer.
Crickets are Poikilotherms, so they don’t keep body warmth. Crickets’ bodies contain mainly of water, so if temperature drops below 32°F (0°C), then water freezes, so as cricket’s body. Then crickets are in hibernation mode. It’s hard to say how long it takes for a cricket to die at subzero. Though, it’s known that too long in water freezing temperature kills crickets.
From my experience as a crickets’ farmer I noticed that crickets go into hibernation phase and die without recovery when temperature drops below 18°F (-8°C) for at least 24 hours. I go in more detail about cold temperature and its impact on crickets – you can read it here.
There is not much research done to exactly evaluate how different cricket species react to cold temperatures. Though, some laboratory tests were done specifically for a House cricket (Acheta Domesticus). The test showed that a House cricket dies without capability to recover when temperature drops below -6°F (-21°C) for a longer than 36 hours.
What Do Crickets Do In Winter?
Crickets die each year and usually don’t live longer than several months. Lifespan per cricket species varies. Read more about it in my other article here.
Crickets die before winter comes and temperature drops. When temperature drops below 59°F (15°C), then crickets stop chirping. By then crickets are still alive, but moving slower and look like being dizzy.
Before finter, during fall months temperature decreases each day significantly. Usually around end of September and start of October you will no longer hear the chirping of crickets.
Though, there could be days when temperature increases during day time. Then it’s not unusual to hear crickets chirping during the day.
One time in my crickets’ farm there was an electricity outage in December. The farm is based in north Europe. I use electrical elements to warm up the farm. Outside the temperature was -50°F (-10°C). Within couple hours temperature dropped inside to 53°F (12°C). Crickets became more silent each minute. After some time it was dead silence.
After 3 hours electricity came back up crickets started chirping again shortly after.
Same happens in nature. In the fall during the nights, crickets stop chirping due to cold weather. Next day, if it’s warm enough you can still hear them.
Temperature in fall and winter differs, depending on geographical location. Though, in average latitude in the late fall during day time thermometers don’t show above 59°F (15°C). In such period you will not hear crickets anywhere. At this time crickets are entering hibernation phase. Crickets can still slowly move, but when weather comes closer to water freezing temperature, then a cricket dies.
If temperature stays 18°F (-8°C) or lower for at least 24 hours, then crickets can be considered dead.
Before dying, crickets lay their eggs in humid area. Eggs make through the winter. When winter ends and new warm season starts, then eggs hatch and new cycle begins.
What Season Do Crickets Go Away?
Crickets usually die off in fall. Different temperature levels impact crickets’ behavior differently.
- Crickets stop chirping when temperature drops below 59°F (15°C).
- Crickets go into hibernation phase when temperature drops below 32°F (0°C).
So, if you hear a cricket in your house and cannot get rid of it yourself – you just need to wait for temperature to drop below mentioned thresholds for chirping to stop and for cricket to die. Crickets don’t live in colonies, so there’s a little chance that at the same time more than one cricket is inside your home.
Each geographical area reach mentioned temperatures at different months. Here’s the summary chart with temperature averages per month in North America:
In the chart red line shows the temperature when crickets stop chirping. Below chirping temperature 59°F (15°C) transitions to crickets’ hibernation phase. When chirping stops crickets try to hide in dark cracks where direct sunlight is not reaching.
So, we can consider that crickets go away for the season when they stop chirping and are no longer noticeable.
In North America crickets usually go away in fall. Though, when crickets stop chirping and start hibernate differ per location.
- In Alaska there’s no suitable season for crickets to survive to reach chirping temperatures. It means crickets don’t live in Alaska.
- In Canada crickets go away in fall season. September’s average temperature drops below 59°F (15°C), so crickets stop chirping around start or mid of fall. November and December crickets start hibernating and die until spring.
- In Florida crickets don’t go away any season. All seasons are warm enough for crickets survive at all times. So, crickets don’t die off due to low temperatures, but due to end of a lifespan cycle.
- In New York (NY) crickets go away in fall season. October’s average temperature drops below 59°F (15°C), so crickets stop chirping. During end of fall and start of Winter crickets start hibernating and die until spring.
- In California crickets go away in fall season. California has different climate areas, so crickets’ activity varies. Though, on average only in November average temperature drops below 59°F (15°C) when crickets stop chirping. All seasons are warm enough for crickets to have high enough metabolism and mate. So, crickets don’t die off due to low temperatures, but due to end of a lifespan cycle.
Can Crickets Die From Heat?
There are no studies made to evaluate how high temperature kills a cricket.
Though, what is known that crickets’ metabolism increases with high temperatures. The higher temperature, the faster metabolism.
For example, crickets start to chirp more actively (only males chirp) when temperature increases. Increased metabolism shortens crickets’ living period. Usually crickets live several months if conditions are proper (life span depends on crickets’ species).
So, there are no studies about what temperature is too hot for crickets, but it’s well known that high temperatures increases crickets’ metabolism which results in shorter lifespan.
Perfect temperature for crickets to live is 80-90°F (27-32°C), so everything above such temperatures should decrease cricket’s lifespan.
Do Crickets Die Without Food?
How long can crickets live without food? Without food crickets may stay alive for weeks. Though, the answer to such question is debatable. No research has been done on this topic.
Generally, if crickets in captivity are bred for human consumption or pet food, then before harvesting crickets are left in breeding tanks without water and food for around 2 days. This is needed for crickets to clear their digestion system.
In my crickets farm keeping crickets without food for 2 days I didn’t see any noticeable changes in behavior. They are chirping and moving around as actively as with food.
Of course, 2 days is not enough to evaluate crickets’ capabilities of how long they could live without food.
In nature crickets eat grass, leaves, seedlings, meat, fruits. Basically anything organic. You shouldn’t expect for cricket to die quickly if it’s stuck somewhere inside your home.
In my another article you can read more about what do crickets eat.
Crickets will keep themselves alive by finding insects/ants inside the walls/floor/ceiling, crumbs or other organic material.
How Come My Crickets Keep Dying?
In my farm I keep 200 containers (19 gallon / 70 liters) with live crickets. I understand that farming commercially is different from keeping 1 colony of crickets on your shelf for your bearded dragon to feed.
Though, fundamentally crickets’ dying reasons usually are very similar. From my experience, these are the main reasons why your crickets keep dying:
- Wrong temperature
- Wrong humidity with bad ventilation
- Unsanitary container
- Not enough of nutritious food
- Insufficient water supply

Do Dead Crickets Attract More?
No, dead crickets do no attract more crickets.
If you heard a cricket chirping inside your house and after a while you don’t hear it anymore, there’s a good chance the cricket died inside your house.
If it’s only one cricket’s body there’s not issue – you will not smell it. Especially if the area is kept dry, cricket’s body will just dry and nothing will happen. Though, it can attract other home invaders, such as mice. So, if you can reach it, remove a dead cricket from your home.
In nature crickets don’t live in colonies, so to get multiple crickets inside your house at once is barely possible. So, there’s 0 chance that a dead cricket would attract more crickets.
