As Roseville transitions from our long, dry summer into cooler, wetter fall weather, homeowners start thinking about gutters, drainage, roof leaks and getting the yard ready for rain.
There is something else worth adding to that fall home-maintenance checklist: termites.
Subterranean termites are common throughout California and live primarily in the soil beneath and around structures. Because they depend on moisture, conditions around a home can play an important role in where they forage and how they reach structural wood.
For homeowners in Roseville, California, the beginning of the rainy season is a good time to check for moisture issues and signs of termite activity before small problems have a chance to become bigger ones.
Does Rain Cause Termites in Roseville?
Not exactly.
Rain does not suddenly create a termite infestation. A subterranean termite colony may already be living underground somewhere around a property without the homeowner ever knowing it.
What moisture can do is create conditions that are more favorable for subterranean termite activity.
According to UC Integrated Pest Management, subterranean termites require moist environments and typically maintain a connection with the soil. Warm temperatures combined with higher soil moisture can create favorable conditions for foraging.
Certain subterranean termite species may also produce visible swarms on clear days following a soaking fall or spring rain.
That is why the transition into Roseville's wetter months is a smart time to pay attention to what is happening around your foundation, crawlspace and exterior walls.
Why Roseville Homeowners Should Pay Attention Before the Rain
Homes throughout Roseville can have a mix of slab foundations, crawlspaces, landscaping, irrigation systems, patios, fences and other features that affect moisture around a structure.
A drainage issue that seems minor during summer can become much more noticeable once regular rain arrives.
Think about areas where water may collect:
- Along the foundation
- Beneath downspouts
- Around planter beds
- Near irrigation lines
- Under decks
- Inside crawlspaces
- Around exterior plumbing
- Near wood fencing or posts
- In areas where the yard slopes toward the home
Reducing unnecessary moisture does more than help maintain your property. It can also make conditions less favorable for subterranean termites.
What Are Subterranean Termites?
Subterranean termites live and establish their colonies in or near the soil.
Unlike drywood termites, which can live entirely inside wood, subterranean termites generally travel between their underground colony and a food source.
And unfortunately, that food source can be the wood in your home.
To travel above ground while maintaining the protected, humid environment they need, subterranean termites construct shelter tubes, commonly called mud tubes.
These tubes can extend from the soil across concrete, foundations or other surfaces until termites reach wood.
Because so much of their activity happens underground or inside structural components, termite damage can develop without obvious insects crawling around your home.
5 Things Roseville Homeowners Should Check Before Fall Rain
Before the wetter weather settles into Roseville, take a few minutes to walk around your property.
1. Clean Your Gutters
Leaves, dirt and other debris can keep gutters from draining properly.
When rainwater overflows, it may repeatedly saturate areas next to the structure.
Clean gutters and make sure water can move freely toward the downspouts.
2. Check Where Your Downspouts Drain
Look at where water goes after it leaves the roof.
Downspouts should direct water away from the foundation, rather than allowing it to collect against the home.
If you notice erosion, standing water or consistently wet soil next to the foundation after rain, the drainage should be evaluated.
3. Look for Standing Water
Walk your property after irrigation or rainfall and look for areas where water remains.
Pay particular attention to:
- Low spots next to the house
- Planter beds
- Crawlspace areas
- Leaking hose bibs
- Irrigation valves
- Sprinkler leaks
- Air-conditioning drainage areas
UC IPM recommends repairing plumbing leaks, correcting faulty grading and keeping substructures dry as part of termite prevention.
4. Reduce Wood-to-Soil Contact
Wood sitting directly against the soil can create favorable conditions for subterranean termite activity.
Look for:
- Firewood stacked against the house
- Scrap lumber
- Fence posts
- Landscape timbers
- Wood debris
- Tree stumps
- Other cellulose material near the structure
Whenever possible, keep stored wood away from the home and avoid unnecessary wood-to-soil contact.
5. Look for Mud Tubes
One of the most recognizable signs of subterranean termite activity is a mud or shelter tube.
These narrow, soil-like tubes may appear along:
- Foundation walls
- Concrete
- Crawlspace supports
- Plumbing penetrations
- Garage walls
- Areas where soil meets the structure
Subterranean termites construct these tubes to travel between the soil and wood while protecting themselves from dry conditions and predators.
If you find something that looks like a mud tube, it is worth having it professionally inspected.
What Do Termite Swarmers Mean?
Fall rain can also bring one of the most noticeable signs of termite activity: swarmers.
Swarmers are winged reproductive termites that leave established colonies to mate and potentially establish new colonies.
UC IPM notes that common California subterranean termites can swarm on clear days following soaking rain during the fall or spring.
You might notice:
- Groups of winged insects outside
- Termites emerging from the soil
- Discarded wings around windows or doors
- Wings near a foundation
- Winged insects appearing inside the home
Seeing termite swarmers outdoors does not automatically mean your home is infested. Colonies may be located in soil, tree stumps, buried wood or other cellulose sources nearby.
However, swarmers emerging from the structure or appearing repeatedly inside the home deserve professional attention.
And because flying ants and termite swarmers are commonly confused, proper identification matters.
What If You Don't See Any Termites?
That is normal.
Most homeowners with subterranean termite activity are not going to see termites walking around the house.
The insects can remain hidden:
- Underground
- Inside wood
- Behind walls
- Beneath flooring
- Inside crawlspaces
- Within shelter tubes
By the time obvious wood damage appears, activity may have been present for quite some time.
This is one reason UC IPM recommends professional inspections when termite activity is suspected.
Common Signs of Subterranean Termites in Roseville Homes
Keep an eye out for:
Mud tubes
Thin soil-like tunnels traveling from the ground toward structural wood.
Swarmers
Winged termites appearing around the property, particularly following rain.
Discarded wings
Small piles of wings near windows, doors or other areas where swarmers have emerged.
Damaged wood
Wood may appear blistered, darkened, hollow or weakened.
Termite activity in a crawlspace
Crawlspaces can provide termites with access to structural components while keeping activity largely out of sight.
None of these signs should be used alone to determine the extent of an infestation. A termite inspection can help determine what is actually happening.
Don't Wait for Visible Termite Damage
One of the biggest mistakes homeowners can make is assuming, "I don't see termites, so I don't have termites."
Subterranean termite colonies operate largely out of sight.
Preventive maintenance around your Roseville home can help reduce favorable conditions, but it cannot tell you whether termites are already present.
If you find mud tubes, swarmers, suspicious wood damage or unexplained insect activity around your foundation, having the property inspected is the next step.
