Will Fleas Die in a Hot Car?

Fleas will often enter your vehicle through the fur of your pets, or even by simply being on your lap. This can make killing them a very difficult process. Some people believe that turning up the temperature in their car will kill fleas. While this is true, it is important to know that the temperature must be over 95 degrees Fahrenheit for four to six hours to kill fleas. The temperature must also stay over that level for at least two days.

While adult fleas cannot survive high temperatures, fleas that lay eggs or larvae in your car can be killed by the heat. A hot car can kill larvae and adult fleas in as little as four to eight hours. Make sure that you have plenty of space inside your car and remove any fabric from your car.

The temperature of your car is crucial in killing fleas. They can live for up to a month inside your car, but they will not survive if it is too warm. If you have pets, or even just have an empty car, leaving the car in a hot environment will ensure that the fleas won’t survive.

Hot water is also helpful to kill fleas. You can also use diatomaceous earth, a powder that can kill fleas and egg-laying parasites. But it is important to use diatomaceous earth sparingly because it can cause allergic reactions if inhaled. When you use diatomaceous earth, be sure to use a food-grade version.
