Are termites only a problem when you see damaged wood? Unfortunately, that’s not really how it works.

Once you see damage, it means termites have been there for a long time. They quietly live and develop inside wooden structures for years. By the time you notice tiny pellets or discarded wings, they’ve already settled in and built a colony.

And drywood termites make things even trickier. They fly in, move straight into wooden structures like your attic, crawl space, or exterior, and start eating from the inside.

What makes drywood termites in Southern California so prevalent? Well, let’s take a closer look.

Why Southern California is Ideal for Drywood Termites

Southern California provides conditions that make it especially favorable for drywood termite activity. This is due to a combination of environmental factors, as well as common construction materials found within the region.

Warm Climate Supports Year-Round Termite Activity

One of the main reasons why drywood termites are common within the region is due to the warm climate.

Southern California stays warm most of the year. The perfect climate for us, but unfortunately also for them. Without harsh winters or excessively dry climate, there aren’t many conditions to slow or stop their activity.

Swarming Season Brings New Termite Problems

How do termite issues spread so easily?

During early Spring or early Fall in Southern California, flying termites seek other areas to establish colonies. You might notice flying insects around light posts and porch lights and assume they’re flies or moths, but often they’re termites.

Once they land on your home, they drop their wings and try to burrow and start a new colony.

Even if your home has never had termites before, nearby colonies can quickly turn into a new problem.

Drywood Termites Live Entirely Inside the Wood They Infest

Once drywood termites are established, they continue to expand from a single entry point. And don’t leave any physical signs. Once you see them, they’re there. They’ve been there. And have been causing damage the whole time.

That’s why termite control is a continuous maintenance situation.

Some common entry points include:

  • Eaves and fascia boards
  • Roof trim and shingles
  • Attic vents
  • Wooden roof edges

Although not as common, drywood termites can come in through your furniture.
