Termite Swarming Season Timeline 2025: Glendale & Burbank

SEO Next Mile

4 min read

When is peak swarming?

Late July–October on hot, sunny afternoons—often after light rain or heat spikes.

What do swarmers mean?

Reproductive termites (alates) are starting new colonies; visible swarmers = hidden wood damage nearby.

Top signs: Discarded wings on windowsills, pin-sized kick-out holes, frass (pellet-like droppings), and (for subterranean species) mud tubes.

What to do first?

Why this guide (and why now)

You might be wondering why every summer you suddenly see flying bugs near porch lights or along your sliding doors. That’s termite swarming, and in Southern California it tracks with heat, humidity, and seasonal weather patterns. Knowing the termite season Glendale Burbank timeline helps you act before small signals turn into serious structural repairs.

Science corner: Learn how termite biology and weather trigger swarms from UC IPM and product-safety guidance from California DPR. For public-health best practices in LA County facilities, see LA County Vector Control.

2025 Month-by-Month Timeline (Glendale & Burbank)

July – “Wake-Up” Month

First neighborhood reports of winged termites after hot, calm afternoons.

Start baseline monitoring: sticky cards in garages, flashlight checks in crawlspaces, and a tap-test on baseboards for hollow sounds.

Pro move: schedule a pre-swarm inspection with Termike to map risk areas.

August – Peak Flight Activity

Most alates take flight now.

Common homeowner sightings: discarded wings near door tracks and frass beneath picture frames or beams (drywood), or mud tubes on stem walls (subterranean).

This is the core of termite season Glendale Burbank—don’t DIY spray swarmers; that ignores the colony.

September – Quiet… but Not Safe

Flights taper, but colonies expand in wood members.

Targeted eco-friendly treatments and sealing entry points now prevent winter spread.

If you’re seeing blistered paint or sagging trim, add a damaged wood repair estimate to your plan.

October – Lock-In & Long-Term Protection

Finish exclusion and preventative coatings before cooler nights set in.

Confirm there’s no activity in the attic, subfloor, or fence lines.

End-of-season report from Termike documents any hotspots to watch during the next termite season Glendale Burbank cycle.

Spot the Swarm Early: 6 Visual Cues

Discarded, equal-length wings (termite wings match; ant forewings are longer).

Frass (drywood pellets) that look like tiny, ridged coffee grounds.

Mud tubes (subterranean) running up foundation or garage walls.

Pin-sized kick-out holes in drywall or trim, sometimes with frass beneath.

Hollow-sounding wood when tapped with a screwdriver handle.

Short-lived flights indoors clustered around windows and lights.

Need help confirming species? Compare anatomy and gallery damage using UC IPM photos, then visit Drywood Termites or Subterranean Termites for treatment paths.

Glendale vs. Burbank: Same Region, Slightly Different Risks

Glendale: More hillside homes and vintage wood framing can conceal drywood colonies in rafters and fascia. Regular attic checks are critical.

Burbank: Hotter valley temps push intense afternoon flights; irrigated landscapes can elevate subterranean pressure along foundations.

Either way, a consistent playbook during termite season Glendale Burbank pays off.

Termike’s Inspection Methodology (What We Actually Do)

Interview & history – recent renovations, leaks, or fence replacements.
FLIR thermal scan – finds moisture gradients that attract termites.
UV tracking dust – non-staining tracer to map active foraging.
Entry-point audit & sealing – eaves, utility penetrations, subfloor vents.
Species-specific plan – drywood vs. subterranean protocols.
Report + prevention calendar – so you know exactly what happens next.

Eco-Friendly Options (When Chemistry Isn’t Your First Choice)

Localized orange-oil injections for accessible drywood galleries.

Heat treatments for discrete areas—no residuals, fast turnaround.

Low-impact baiting & reduced-risk products approved by California DPR.

See our Eco-Friendly page for solutions suited to kids, pets, and sensitive environments.

Prevent Before (and During) Swarm Season

Before July

Fix moisture: gutters, downspouts, grade slope.

Store firewood 20+ feet from the house.

Paint/seal exposed fascia and trim (drywood hate sealed entry).

July–October (active months)

Weekly visual checks of sills, window tracks, and exterior lights.

Don’t vacuum frass without snapping a quick photo for your inspector.

If you see mud tubes, do not break them—that erases useful diagnostic clues.

After October

Request a post-season scan to verify no residual activity.

FAQs: Glendale & Burbank Termite Season

When does termite swarming start?

Late July most years, then peaks in August.

Do flying termites bite?

No. The danger is structural—swarmers indicate a mature colony nearby (see About Termites).

Can I handle this with store spray?

Sprays kill visible swarmers but not the colony. Book a professional inspection.

What’s the difference between drywood and subterranean?

Drywood live inside wood and expel frass; subterranean rely on soil contact and build mud tubes. See Drywood vs Subterranean guides.
