Are termites active year-round?

Yes. Subterranean termites work year-round underground. Cold weather does not stop their activity—it just pushes it deeper into the soil and closer to your home.

Why This Happens

Subterranean termites live below the frost line, where temperatures stay stable even in winter. While you may not see surface activity, the colony keeps feeding as long as it has access to wood and moisture.

In Northern Virginia and Southern Maryland, our winters are cold enough to slow insects above ground—but not cold enough to shut termites down. Foundations, crawlspaces, basements, and slab edges provide warmth, moisture, and food all year.

That’s why termite damage is often discovered in winter or early spring. The activity didn’t “start” then—it was already happening out of sight.

What This Means for Your Home

A common myth is that termites die off or leave in winter. They don’t. They simply stay hidden and keep working.

This matters because damage doesn’t pause with the seasons. Even slow, steady feeding adds up over time. By the time visible signs show up, termites may have been active for months—or years.

For homeowners, this can feel unsettling. The good news is termites aren’t a direct danger to people or pets. The real risk is structural damage and repair costs if activity goes unnoticed too long.

How Professionals Address It

A proper termite plan isn’t seasonal—it’s year-round protection.

Professionals start with a careful inspection to:

• Confirm termite activity and type

• Identify moisture and access points

• Understand how the structure is being affected

From there, the focus is on cutting off access, protecting the home from the outside in, and correcting the conditions that let termites stay active. Interior work is only used when inspection shows it’s truly needed.

This approach recognizes one key fact: termites don’t take the winter off, so protection shouldn’t either.

What Homeowners Can Do Now

Safe, smart steps you can take at any time of year:

• Keep soil, mulch, and wood from touching siding or trim

• Fix moisture issues near foundations, crawlspaces, and basements

• Store cardboard and paper items off floors and away from walls

• Watch for signs like mud tubes, wings near windows, or soft wood

• Make a note of where and when you notice anything unusual

Avoid seasonal “wait and see” thinking. Termites don’t operate on a calendar.

When to Call a Professional

If you suspect termites—or if your home hasn’t been inspected in several years—there’s no wrong season to call a professional. Winter inspections are just as valuable as spring ones, and often more revealing.

An inspection gives you clarity, not pressure. It helps you understand whether termites are active now, what conditions are contributing, and how to protect the home long-term.

If you’re in Northern Virginia or Southern Maryland and want an inspection-first, outside-focused approach, Planet Friendly Pest Control can walk you through your options calmly and clearly.

Damage can happen in any season. The risk depends on how long activity goes untreated, not the weather.
