Which Months Are Fleas Active?

While fleas are most active in warm weather, they can also be present year-round. During the cold months, flea eggs lay dormant. As the weather warms up, the eggs hatch and fleas start biting pets. This can make your pet itchy and uncomfortable.

In warm areas, fleas are most active between the months of March and December. As you move north, flea season gets shorter. However, you never know when fleas will attack. It’s best to be prepared with an insecticide spray during the warmer months. Whether it’s November or March, you’ll want to prevent your dog from coming into contact with fleas.

Fleas and ticks can cause problems for your pet year-round. During the cooler months, fleas find shelter indoors and become active again. However, in some areas of the United States, fleas can become active as early as March. Since fleas have such a long life cycle, it can be difficult to get rid of them completely.

Fleas and ticks are most active in warm climates, with humidity levels between 50 and 90 percent. In colder regions, fleas and ticks become dormant, but they can still be active during warm weather. Generally, however, the active season for fleas and ticks is spring and summer. They can survive temperatures of up to 70 degrees Fahrenheit.
