If you have a dog or cat, you probably know it’s important to administer flea prevention medicine. However, you may wonder if it’s necessary during the fall and winter when fleas become less active. Here’s a closer look at the dangers of fleas and how the colder months may still require the vigilance of pet owners. 

What Problems Can Fleas Cause? 

Fleas are tiny, wingless insects that feed on the blood of humans and animals. Dogs and cats that have been bitten by fleas may experience severe itching, particularly if they’re allergic to flea saliva. In addition, fleas often carry tapeworm larvae. If your pet eats a flea, they may contract tapeworms, which can spread to humans and cause symptoms like nausea, diarrhea, and abdominal pain. 

Since fleas feed on blood, they can also cause anemia—a lack of healthy red blood cells—in dogs and cats. This condition may induce lethargy, loss of appetite, and yellow gums. If not treated promptly, anemia can lead to serious complications, including death. 

Flea bites can also lead to a Bartonella infection. This bacteria can spread to humans and cause several diseases. For example, a condition known as cat scratch disease produces symptoms like fever, vomiting, and swollen lymph nodes. 

Does Your Pet Need Flea Prevention Medicine When It’s Cold? 

Contrary to popular belief, not all fleas die during winter. They can survive temperatures in the low 30s for up to five days, which gives them plenty of time to cling to your pet and enter your home. Once inside, fleas can comfortably spend the winter on your pet’s warm skin.

In addition, any flea eggs that end up in your home during the warmer months could mature into adult fleas during the winter. That’s why it’s important to give your pet flea prevention medicine all year long.
