How Hot Kills Fleas
Heat is an effective way to kill fleas, but it’s not the only way to get rid of fleas. You should also consider the humidity levels of the areas you want to treat. Fleas thrive in warm, moist places. In fact, they need a humidity level of at least 70% to die. Therefore, it’s important to understand where fleas are most likely to be present, and what kind of climatic conditions they prefer.
Adult fleas can survive for 100 days without a blood meal. Their larvae are less blood-hungry than adult fleas, and can survive off debris in the host’s environment. As adults, fleas lay dormant eggs and cocoons for up to five months, awaiting conditions that will allow them to hatch.
Fleas are a persistent pest, and they often stay on your clothing for a day or two before they go in search of another blood meal. Washing your clothing frequently is an important part of flea control. But if you don’t have time to wash all of your clothes every single day, you can wash them at high temperatures.
In addition to hot temperatures, fleas are more likely to live in a damp or shaded environment. Because of this, it’s important to keep pets indoors during the summer and in the shade if possible. Hotter temperatures will kill fleas, but you should check your pets for ticks as well.
