What You Need to Know

Fleas are known to be resilient pests that can be difficult to eliminate. Many people wonder if leaving fleas in a hot car will result in their death. A recently conducted study aimed to answer this question and provide valuable insights on the topic.

Fleas and their Resilience

Fleas are capable of surviving in various environments, including hot temperatures. These miniature pests are known to live and lay eggs in cars, especially in regulated temperatures. While adult fleas have a lower tolerance for heat, flea eggs can withstand even higher temperatures.

Surviving in Hot Temperatures

Fleas have some resilience when it comes to hot temperatures. Most adult fleas will not survive temperatures above 85°F. However, they need to be exposed to the heat for at least one hour in order to ensure their death.

Heat Needed to Kill Adult Fleas

To kill adult fleas effectively, a hot car must reach a temperature of more than 100°F. This can be achieved by parking the car in direct sunlight with all the windows closed. When the car reaches this temperature, the fleas will be eliminated. It is important to note that it may take some time for the car to heat up, so patience is required.

Heat Needed to Kill Flea Eggs

Flea eggs, on the other hand, require even higher temperatures to be killed. Exposure to approximately 100°F for at least 30 minutes can lead to the death of flea eggs. It is recommended to use a higher temperature if possible to ensure complete elimination.

Methods to Kill Fleas Inside a Car

Park in Direct Sunlight

One method to kill fleas inside a car is to park the vehicle in direct sunlight on a hot day. Close all the windows and doors, and leave the car parked for at least one hour. Keeping the engine running with the air-conditioning turned off will help in heating up the car to a temperature that can kill the fleas. However, it is essential to ensure that nobody else is in the car, as it can become extremely hot.

Vacuum Your Car

In some cases, heat alone may not be sufficient to eradicate fleas. Vacuuming all upholstered surfaces and carpets within the car is crucial. Special attention should be paid to cracks and crevices where fleas might be hiding. After vacuuming, using a handheld steamer can kill any remaining fleas and their eggs.

Use a Flea Bomb

For severe flea infestations, the use of a flea bomb may be necessary. A flea bomb is a device that releases insecticide into the air, effectively killing fleas. It is important to carefully follow the instructions and evacuate the area for the specified duration mentioned on the product. After the use of a flea bomb, vacuuming the car again is essential to eliminate any dead fleas. However, it is worth noting that using a flea bomb too frequently can damage the car’s interior.

Causes of Fleas Inside a Car

Pets

One of the most common ways fleas find their way into cars is through pets. If you frequently travel with your pet in the car, it is likely that they may bring fleas with them at some point. Regularly treating pets for fleas and keeping them clean can help prevent this.

Clothes & Shoes

Another way fleas can enter a car is by hitchhiking on clothes or shoes. If you have been in an area where fleas are present, they can easily jump onto your clothes and be transported into your car. Taking precautions like shaking off clothes and checking for fleas can be helpful in preventing their entry.

Passengers

If you have passengers in your car, they may unknowingly bring fleas with them. This is particularly true if they have been around animals or areas where fleas are prevalent. Keeping the car clean and regularly inspecting for fleas can help prevent infestations.

Conclusion

While it is technically possible for fleas to die in a hot car, achieving the necessary high temperatures, around 100°F to 120°F, would require parking the car in direct sunlight with all windows closed for an extended period of time. In general, fleas will not survive in a car for more than one week if the area is clean and there are no pets present to provide them with a food source. Regular cleaning, using a vacuum cleaner, and employing a flea bomb when necessary are additional methods that can be used to kill fleas. It is important to remain diligent and consistent in efforts to eliminate these pests to prevent future infestations.
