Most people think of spring as termite season, but in Sacramento, termites can also be a major concern during the fall. Subterranean termites (the most common species in Northern California) often swarm when temperatures drop and conditions are right. For homeowners, this can be confusing and even alarming, especially if winged termites suddenly appear inside or around the house.
At Pest Pros Pest Solutions, we know how destructive termites can be. Our Sacramento team helps homeowners understand the habits of these pests, why swarm season matters, and how to protect homes from costly structural damage.
What Is a Termite Swarm?
A swarm is how termites reproduce and spread. Winged termites, known as alates, leave their colonies in large groups to mate and establish new nests. During fall swarm season in Sacramento, you may notice clouds of flying insects near windows, doors, or outdoor lights.
It’s easy to mistake them for flying ants, but termites can be identified by:
Straight antennae (ants have bent antennae)
Equal-sized wings that are longer than their bodies
Straight, uniform waists (ants have pinched waists)
Spotting swarmers doesn’t necessarily mean your house is being eaten yet, but it does indicate termite activity nearby.
Why Does Swarm Season Happen in the Fall?
Termites are sensitive to temperature and moisture. While spring is a common swarm time in many parts of the country, Sacramento’s climate allows termites to swarm again in the fall when cooler nights and occasional rains provide ideal conditions.
This means Sacramento homeowners face a longer risk period than in many other regions. A fall swarm may indicate a colony that has been active all summer and is looking to expand before winter sets in.
Why Are Termites So Destructive?
Unlike nuisance pests such as ants or spiders, termites feed on cellulose — the material found in wood and other plant matter.
In homes, this translates to damage to:
Wooden framing and support beams
Flooring and subflooring
Window and door frames
Drywall and trim
Because termites eat from the inside out, damage is often hidden until it becomes severe. By the time homeowners notice hollow-sounding wood or buckling floors, thousands of termites may already be at work.
Signs of Termite Activity in Sacramento Homes
Catching termite activity early is key to limiting damage. If you see winged insects indoors during the fall, it’s a strong indication that termites may already be nesting in your home.
Some common warning signs include:
Discarded wings near windowsills or entryways after a swarm
Mud tubes on foundation walls or crawlspaces
Hollow-sounding wood when tapped
Frass (termite droppings) that look like sawdust
Sagging floors or ceilings from weakened structural support
How Can You Prevent Termite Infestations?
While you can’t stop termites from existing in Sacramento’s soil, you can make your property less vulnerable to infestation.
Preventive steps include:
Reduce Moisture – Fix leaks, maintain gutters, and ensure crawlspaces are well-ventilated.
Store Firewood Away from the House – Keep it elevated and at least 20 feet from the foundation.
Seal Entry Points – Caulk gaps around plumbing, vents, and wiring.
Schedule Inspections – Professional termite checks help detect activity early before serious damage occurs.
When to Call for Help
DIY treatments rarely work against termites because colonies can contain hundreds of thousands of insects spread deep underground. Spot-treating a visible swarm won’t eliminate the source of the problem.
That’s why many Sacramento homeowners turn to Pest Pros Pest Solutions during fall swarm season. Our team has the tools to identify termite species, locate colonies, and apply proven treatments that stop infestations at the source. Regular monitoring and preventive services can also help protect your home year-round.
