What Causes Termites? What Granville Homeowners Should Know

A narrow mud tube on a foundation wall or a pile of shed wings near a window can be easy to overlook. For Granville homeowners, those small signs often raise a bigger question: what causes termites, and why would they choose one house over another?

The answer usually comes down to wood, moisture, soil access, and protected entry paths. What causes termites to become a problem is not one single issue, but the way those conditions line up around a home. Because eastern subterranean termites are the species Green Shield Pest Pros treats across Central Ohio, the focus here stays on conditions that help them reach structural wood.

This guide explains the attractants, entry points, and warning signs to check, plus when an inspection makes sense.

Key Takeaways

• Termites are drawn to accessible wood, excess moisture, and conditions that let them move from soil to structural wood.
• Subterranean termites use mud tubes to travel from the ground to protected feeding areas around a home’s foundation.
• Discarded wings, bubbled paint, hollow-sounding wood, frass, and mud tubes are warning signs worth checking.
• Green Shield Pest Pros inspects the interior and exterior of homes before recommending termite protection or treatment.

What Causes Termites Around Granville Homes

Termite pressure builds when the area around a home gives termites food, moisture, shelter, or a path into wood. The clearest attractants are usually close to the foundation, where small maintenance issues can create easy access.

Wood That Attracts Termites

Termites feed on wood and other cellulose material, so accessible wood is one of the main reasons they move toward a home. Untreated lumber, stored wood, wooden trim, framing, or other cellulose-based belongings can become attractive when termites can reach them from nearby soil or sheltered areas.

Excess Moisture Near the Foundation

Moisture is one of the strongest conditions that attracts termites. Oregon State University Solve Pest Problems notes that treatments for subterranean termites do not work as intended unless moisture sources are removed and damaged wood is repaired, so leaky faucets, poor drainage, and moisture-damaged wood deserve attention.

Wood-to-Soil Contact

Subterranean termites live in soil and forage outward in search of wood. When wooden parts of a home touch or sit close to the ground, termites have a shorter, more protected path from the colony to the material they consume, especially near siding, supports, or framing.

Mulch, Woodpiles, and Raised Soil

Homeowners may inadvertently hide early termite activity by placing woodpiles against exterior walls, using mulch beds directly against the foundation, or allowing soil to be graded high enough to touch siding. 

These factors create an environment where cellulose materials are dangerously close to the ground, providing termites with the ideal conditions to flourish unnoticed.

Dampwood and Drywood Termite Conditions

Different types of termites behave differently. Drywood termites do not need soil contact or liquid moisture and may affect wood items such as furniture and picture frames, while dampwood and subterranean termites generally call for professional control when they affect a home. In Central Ohio, Green Shield Pest Pros treats eastern subterranean termites.

How Termites Get Inside Granville Homes

Once termites find the right conditions near a house, they still need a protected route inside. For subterranean termites, those routes usually begin in the soil and continue toward wood that sits close to the home’s foundation.

Mud Tubes on Foundation Walls

Subterranean termites build mud tubes between soil and wooden structures to protect workers from open air. UC IPM describes these shelter tubes as a sign of termite activity, and they often appear on foundation walls, basement supports, porch supports, or other vertical surfaces.

Basement and Crawl Space Framing

Basement walls, crawl spaces, and areas where wooden framing contacts or sits close to soil can give termites a concealed route into a structure. These spaces often stay out of daily view, which makes them important areas during an interior and exterior termite inspection.

Porch Supports and Utility Penetrations

Exterior porch supports and utility penetrations can create narrow paths from soil to wood or sheltered wall areas. If termites build mud tubes around these spots, the activity may stay tucked along edges, corners, or service lines until someone checks the exterior closely.

Garage Slab-to-Wood Transitions

Garages with direct slab-to-wood transitions can be vulnerable because wood may sit close to the ground-level edge of the structure. Checking these transitions helps identify places where termites could move from soil-adjacent areas into framing without leaving obvious indoor signs right away.

Warning Signs Granville Homeowners Should Check

Termite warning signs are often small at first, and the damage can stay hidden inside wood or behind finished surfaces. Checking the right clues helps you decide when a closer inspection is needed.

Discarded Termite Wings

The University of Georgia termite guide describes swarmers as winged reproductive termites with two pairs of wings that are roughly equal in size. After a swarm, those wings can collect on floors, windowsills, or near light fixtures, making shed wings one of the easiest indoor signs to notice.

Mud Tubes Around the Home

Mud tubes along the foundation, basement supports, porch supports, or utility areas are a clear sign that subterranean termites may be moving between soil and wood. These tubes often look like narrow earthen lines and should be checked before the feeding area expands.

Bubbled Paint on Interior Walls

Paint that looks bubbled, uneven, or raised on interior walls can point to activity beneath the surface. This sign does not confirm a termite infestation by itself, but it gives a service professional a specific area to inspect alongside other evidence.

Hollow-Sounding Wood Trim

If trim, baseboards, or other wood sounds hollow when tapped, termites may have damaged the inside while leaving a thin surface behind. The University of Tennessee Extension notes that termite presence may go unnoticed until swarming, which is why hidden damage deserves attention.

Drywood Termite Frass

Drywood termite activity is often marked by uniform fecal pellets, called frass, beneath infested wood. These pellets are about the size of grains of sand and may appear on flat surfaces below the feeding site, including areas under furniture, frames, or trim.

Schedule a Granville Termite Inspection

If you find signs of termite activity, Green Shield Pest Pros starts with an inspection of both the interior and exterior of your home. The inspection looks for visible activity, moisture problems, vulnerable access points, and places where termites may already be reaching wood.

Green Shield Pest Pros performs 600 termite inspections per year for builders across new homes and neighborhoods, and that same inspection process is available for existing homes. The EPA termite resource can help with basic identification, but a professional inspection gives you a clearer plan for your specific property.

When the inspection reveals eastern subterranean termite activity, Green Shield Pest Pros uses the Sentricon inground baiting system around the home. The system uses termite worker behavior to share bait within the colony. If active interior damage is present, Green Shield Pest Pros can use a foaming product or above-ground station at the affected area.

Understanding what causes termites helps you catch the conditions before they get worse. Contact Green Shield Pest Pros to schedule a Granville termite inspection and talk through the next step for protecting your home.
