Rats’ Heat Tolerance can’t tolerate high temperatures for a lengthy period, indoors or outside. When the air temperature is too high, they will swiftly overheat and perish within minutes of entering an indoor area, such as an attic.
According to some research, rats may leave if the attic becomes too hot during the day. However, these rodents can escape the extreme temperatures found up there as long as they have some access to the cold and fresh air.
Rats can withstand a wide range of temperatures, but the winter is when they are most likely to seek out the warmth of a house. It gets harder for them to regulate their body temperature and keep hydrated in the heat. As a result, the rat may find the high temperatures in a heated attic rather intolerable. In simple terms, rats can live in a hot attic.
Rats frequently migrate around in search of the finest possible mix of food and shelter. It implies that they will transfer to a location nearer the outdoors if they feel too warm.
They may spend a few days or even weeks in your attic as a result of this migration during the summer. When it’s hot somewhere else, they may keep cool there while looking for food when it’s chilly somewhere else.

Can Rats Live In Hot Attic? An Explanation
Rats are more likely to die from overheating in hot weather than in colder weather, especially if they are used to hiding in the attic.
If the temperature in your attic is too high for them during the hot summer, rats will often search for cooler areas as long as there are no restrictions on their movement. However, if they have ready access to water, they may be able to cool down and stay in the attic even if the attic becomes too hot.
Rats will do their best to stay outside the attic during the hot summer. That is because while the outside air is only 95–97 degrees Fahrenheit, the temperature in the attic can reach extremes of up to 150–160 degrees.
Rats will leave the attic in the summer heat. You can still see them racing around the yard early in the morning and late at night. Most of the time, they spend the day outside and come inside at night.
If they sense danger, rats will leave a place, especially if they know there is an exit. They risk dying if their departure is obstructed. These animals immediately grow anxious and overheat. Even if rats still have access to food, it’s unlikely that they will stay in the attic on a hot summer day.
If you think you have a rat problem, you should get rid of them as quickly as possible, fix any damage they’ve done, and take steps to prevent them from coming back into your attic.
What Temperatures Are Favourable For A Rat and How Can You Tell If A Rat Is Overheating?
Rats find temperatures between 60 and 72 degrees Fahrenheit favourable for them to grow. The rat must regulate temperature through its skin surface to maintain ideal body temperature, which fluctuates between 66 and 73 degrees Fahrenheit.
As a result, a rat is susceptible to heat stress, heatstroke, and even a heart attack when exposed to intense heat for an extended period.
The rat’s body temperature rises sharply if it’s thirsty and overheated. The rat may be hyperthermic when dehydration sets in, resulting in heatstroke. Low energy, diarrhea, lethargy, lack of appetite, difficulty breathing, red spots on the skin, convulsions, and death are some of the signs and symptoms of heat exhaustion.
The rat also requires access to water at all times and a place to hide or cover when the temperatures outside or indoors are extremely high.
Rats can’t sweat very well; therefore, they avoid being too hot by leaving hot locations or settling near water sources where they may cool down by splashing water over their bodies.
Can Rats Tolerate Heat?
Rats can’t tolerate heat well. Therefore prolonged exposure can be fatal. Rats are nocturnal. Thus they have not adapted to withstand extremely high temperatures and humidity.
The time it takes for the body to become extremely dehydrated and heated decreases as the temperature rises.
These animals will feel uncomfortable in temperatures exceeding 90 °F. When the temperature rises to about 98 degrees Fahrenheit, rats won’t’ survive for more than 30 minutes without exhibiting discomforts, such as heavy breathing, elevated pulse rates, trouble standing on wobbly legs, and lethargy.
These symptoms worsen after an hour of exposure and may cause convulsions, a coma, or even death. For them, temperatures exceeding 104 degrees Fahrenheit will cause death.
The good news is that these rats can stay in an attic for a shorter period when the temperature rises. Doing this may significantly lessen their time in your attic and the amount of harm they inflict on your home.
Can Heat in the Attic Kill Rats?
Even in the summer, attics rarely become hot enough to kill rats. On the other hand, rats demand temperatures of 65 to 80 degrees Fahrenheit. Anything higher than this will make them uncomfortable—the threats to their health increase as the temperature rises.
High attic temperatures could be useful for controlling rodents. However, you must make sure that it’s more than 90 to 100 degrees Fahrenheit. Remove any water sources, including leaks, from the attic to prevent rodents from rehydrating.
Final Verdict
Attics may get extremely hot during the summer. Rats always need to cool themselves off and avoid overheating. Thus they can withstand the heat. However, they begin to overheat if the temperature rises over 90 to 100 degrees. You could then question if using heat to manage pests is possible.
Since homes rarely reach temperatures high enough to drive rats outside, most rats can survive in a hot attic.
Rats also adjust by relocating to a cooler location until the temperature drops. They will lick themselves to cool themselves, consume less food, and drink more water. They will also let off more body heat through their tails.
Rats will return to their attic nest as soon as the temperature drops. Rats must be trapped inside if you don’t want them to live there. Eliminate all food and water sources, and seal any holes.
