Termite Control – A Recent Job & Some Homeowner Tips
By David, Owner, Guardian Pest & Termite Services
What I Walked Into
September is a month when I still pay close attention to termite activity around homes in the Greater Charlotte metropolitan area. Summer may be winding down, but the warm ground and moisture we get around this time of year can still give subterranean termites good conditions to stay active.
Earlier this month, I got a call from a homeowner who had noticed something unusual near the back corner of their garage. They were cleaning along the wall when they found a thin line of dried mud running up from the concrete near the foundation.
When I arrived, I started with the area they had found in the garage. The mud line definitely needed a closer look, but with termites, I never want to stop at the first visible sign. What you can see is often only a small part of what's happening.
The Problem
The first thing I confirmed was that the material along the garage foundation was a termite mud tube.
Subterranean termites build these tubes so they can travel between the soil and the wood in a structure while staying protected. Finding one doesn't automatically tell you how much activity is present, so the next step was figuring out where else they had been moving.
I checked the garage wall, foundation, crawl space, and accessible wood around that side of the house. In the crawl space, I found additional activity around one section of the floor system. Some of the wood showed early signs of termite feeding.
Fortunately, we weren't looking at major structural damage. The homeowner had noticed the warning sign early enough that the activity was still fairly localized.
Outside, there were also a couple of conditions worth addressing. Mulch was sitting heavily against parts of the foundation, and one downspout was leaving the soil noticeably damp near the same side of the house where we found the activity.
Neither of those things means termites will automatically show up, but moisture and easy access to cellulose materials can make conditions around a home more favorable for them.
That was the main concern in this case. The tube in the garage was only what the homeowner could see. The activity underneath the home was what actually needed attention.
The Process
I started with a complete termite inspection so I could get a better idea of how far the activity extended.
I checked the foundation carefully for additional mud tubes and then worked through the crawl space, paying particular attention to sill plates, floor joists, support areas, plumbing penetrations, and places where wood was close to the soil.
Once I had a clear picture of the active areas, we could put together the treatment based on what was actually happening rather than treating blindly.
The affected areas were treated to address the existing termite activity, and the foundation was protected to help stop termites moving from the soil into the structure.
The crawl space was another important part of the conversation. I explained which areas should stay accessible so they could be checked again and what warning signs were worth watching for in the future.
With termites, I don't want to simply make the visible tube disappear. I want to understand where they're coming from, address the active problem, and reduce the conditions that can make future activity easier.
The Outcome
After the treatment, we kept an eye on the areas where termite activity had been confirmed.
There were no new mud tubes developing around the garage foundation, and the previously active areas in the crawl space showed no new signs of movement during follow-up.
The homeowner also made the changes we had discussed outside. They pulled the mulch back from the foundation and adjusted the drainage near the downspout so that section of soil wasn't staying as wet after rain.
What they appreciated most was finally understanding what they had found. Before the inspection, they knew the mud line might be termites, but they had no idea whether it meant a small problem or serious damage somewhere inside the house.
Once we had inspected everything and dealt with the active areas, they knew exactly where things stood.
In this case, catching that one small sign in the garage helped us deal with the problem before there was much more damage to repair.
DIY Advice
Before I left, I gave the homeowner a few things they could keep an eye on themselves.
Look for narrow mud tubes running from the soil onto concrete, brick, block, or other parts of the structure.
A thick layer of mulch directly against the house can hold moisture and make the foundation harder to inspect.
Make sure gutters and downspouts aren't leaving consistently wet soil beside the foundation.
Firewood, scrap lumber, cardboard, and other cellulose materials should be kept away from the structure whenever possible.
Wood that sounds hollow, feels unusually soft, or appears damaged without an obvious reason is worth checking.
These checks don't replace a termite inspection, but they can help homeowners notice changes around the property before a problem has more time to develop.
Professional Insight
One of the difficult things about termites is that you can have activity without seeing termites walking around your home.
They spend most of their time in places homeowners don't regularly see. They may be moving from the soil into a crawl space, feeding inside wood, or traveling through areas hidden behind finished surfaces.
That's why I don't judge a termite problem only by the amount of visible damage.
A single mud tube can be worth investigating because it tells us termites have found a route to the structure. On the other hand, breaking the tube or spraying the area yourself doesn't tell you whether the colony or another access point is still active.
The earlier those pieces are identified, the easier it usually is to get ahead of the problem.
Closing
This job started with one small mud tube that could easily have been cleaned away and forgotten about.
Instead, the homeowner questioned it and had it checked. That gave us the chance to find the additional activity underneath the home before there was more extensive damage.
If you're in the Greater Charlotte metropolitan area and you notice mud tubes, discarded wings, unusual wood damage, or anything else around your home that makes you wonder about termites, don't ignore it just because the sign looks small.
It's better to know what you're dealing with early.
