Key Takeaways

  • In San Diego, flea season peaks from spring to fall due to warm, humid weather, though fleas remain active year-round, given the mild climate.
  • The area hosts several flea species, including the cat and dog flea, which can affect you and your pets.

Understanding Flea Season in San Diego

Flea season in San Diego typically spans from the warm spring months to early fall. With the region’s generally mild climate, fleas can remain active year-round.

Factors That Impact Flea Activity

  • Weather: Fleas thrive in warm, humid environments. San Diego’s weather is conducive to fleas being active year-round.
  • Temperature: Fleas are most active when temperatures are between 65°F and 80°F. In Southern California, such temperatures are commonplace in the coastal zones.
  • Climate: The mild, temperate climate of San Diego does not experience the extreme cold that typically suppresses flea populations, potentially leading to extended flea and tick seasons.

While traditional flea season peaks during the warmer months, you should remain vigilant against fleas even during the winter.

Flea Life Cycle

To effectively prevent and control flea infestations in San Diego, it’s crucial to understand the stages of the flea life cycle. Here’s a breakdown:

  1. Adult Fleas: The cycle begins with adult fleas, which feed on blood before laying eggs on their host.
  2. Flea Eggs: These eggs are laid on the host but often fall off into the surrounding environment.
  3. Larvae: The eggs hatch into larvae, which feed on organic debris in their surroundings.
  4. Pupae: Larvae then spin silk-like cocoons, entering the pupae stage and developing into adult fleas.
  5. Emergence: Given the right conditions, new adult fleas emerge from the cocoons, ready to find a host and start the cycle anew.

Impact on Pets and Humans

San Diego’s flea season notably affects both pets and their owners. Here are ways fleas can impact you and your pets:

  • Fleas can transmit diseases. While rare, they can carry pathogens infecting you and your pets.
