Why Are Fleas More Active at Night?

Fleas are active primarily at night. They are less active during the day and more active during the night when they are searching for food or a sexual partner. This means that fleas are less likely to be disturbed and can be easier to kill. Because of this, it is important to treat your pet for flea infestation as soon as possible.

Flea activity is largely dependent on temperature. If the temperatures are too cold, fleas are less active. The temperature needs to be around 35degC with a relative humidity of 70 percent. This combination of temperatures is ideal for flea populations. Fleas can be detected with the help of a light trap. These devices are used to detect fleas in the home.

In warmer months, fleas are more active. This is because they can survive in cooler temperatures, while they prefer a damp, warm environment (70-85 degrees F). Fleas also transmit parasites and bacteria. The bacteria responsible for cat scratch disease, Bartonella henselae, is transferred to humans through flea bites.

Another factor contributing to flea activity at night is the presence of long grass. Long grasses are a favorite host of fleas. It is important to cut the grass to prevent this flea infestation.
