Termite treatment in Pittsburgh usually relies on one of two proven methods. A liquid termiticide applied to the soil around your foundation blocks termites from reaching the house. In-ground bait stations get termites to carry a slow-acting bait back to the colony and eliminate it. Many homes do best with a combination of both, chosen based on the structure and how active the infestation is.
If you’ve found mud tubes on your basement wall or seen winged insects swarming near a window in spring, you’re probably weighing your options and wondering what a professional will do. This guide explains how each method works, why Western Pennsylvania homes present particular challenges, and what to ask before you hire someone.

Why Are Termites a Concern for Pittsburgh Homes?
The species that damages homes in our region is the eastern subterranean termite. It lives in colonies in the soil and travels into houses through cracks, gaps, and wood that touches the ground. These termites don’t need to see daylight to do serious damage. They build mud tubes along foundation walls and sill plates and feed on wood from the inside out, so most homeowners only find out when they notice a swarm, a sagging floor, or hollow-sounding trim.
Pittsburgh’s housing stock makes the problem worse. Many homes here are 70 to 100 years old or older, with stone or block foundations, crawlspaces, wood porches, and decades of settling. Hillside lots, clay soil, and drainage problems keep the soil around foundations damp, and subterranean termites thrive in damp soil. On top of that, freeze-thaw cycles open small cracks in concrete every winter, giving termites new hidden ways into a house.
How Does Liquid Termite Treatment Work?
Liquid treatment creates a continuous treated zone in the soil around and under your home. Termites have to pass through that soil to reach the structure, so a properly applied treatment cuts off their access. It is the most direct way to protect a home that has an active infestation.
What Happens on Treatment Day?
A technician digs a narrow trench along the outside of the foundation and applies termiticide to the soil as it’s backfilled. Where concrete covers the soil, such as at a porch, garage slab, patio, or basement floor along the walls, they drill small holes and inject the treatment beneath the concrete, then patch the holes. Crawlspaces, block wall voids, and plumbing penetrations may also be treated, because termites commonly use them to get in. The exact plan depends on how your home was built, so you should expect a thorough look before anyone starts drilling. Our post on what happens during a termite inspection walks through that first step.
Why Do Modern Liquid Treatments Work So Well?
Most professional termiticides used today are non-repellent, which means termites can’t detect them. Instead of avoiding the treated soil, they tunnel straight through it and pick up the active ingredient. Because termites groom and feed one another, exposed workers spread it to other members of the colony. That transfer effect is a big reason liquid treatments can reduce activity fairly quickly while also protecting the structure going forward.
How Do Termite Bait Stations Work?
Bait stations attack the colony itself rather than building a barrier. Small stations are placed in the ground at intervals around the outside of the home, each holding a cellulose material that termites want to eat. Once termites find a station, the bait is laced with an insect growth regulator that stops them from molting properly.
How Does the Bait Reach the Colony?
Worker termites eat the bait and share it with the rest of the colony as they feed others. Because the bait acts slowly, the workers don’t die before spreading it, which lets it move through the whole population. As termites fail to molt, the colony declines and eventually collapses. This process takes longer than liquid treatment, usually weeks to months, but it targets the source.
Why Does Monitoring Matter?
Bait stations only work if someone checks them and keeps the bait fresh. A station that termites have emptied or abandoned does nothing to protect your home. When you compare contractors, ask how often the stations will be inspected and what happens when activity shows up.
Liquid Treatment vs. Bait Stations: Which Is Right for Your Home?
There isn’t a single correct answer for every house, which is why Stewart uses both methods. Liquid treatment is usually the go-to when termites are already active inside the structure and you need protection right away. Bait stations work well around homes where drilling or trenching is difficult, near wells or sensitive areas, or as ongoing monitoring once an infestation is under control. Many Pittsburgh homes benefit from both: liquid treatment to stop the current problem and bait stations to catch new activity early.
Your foundation type, the location of the activity, landscaping, nearby water sources, and whether there are finished basement walls all affect the recommendation. A good contractor will explain why they’re suggesting one approach over the other instead of offering one package to everyone.
How Do Pittsburgh’s Climate and Older Homes Affect Treatment?
Local conditions shape how well any treatment holds up. Freeze-thaw cycles can crack slabs and open gaps around foundations over time, so a technician should look for new entry points when inspecting a previously treated home. Wet basements, clogged gutters, and downspouts that empty against the foundation keep soil moist and attract termites, so fixing drainage helps whatever treatment you choose. Stone and hollow-block foundations, common in older Pittsburgh neighborhoods, have voids that termites can travel through unseen and often need extra attention.
Season matters too. Termites swarm here on warm days in spring, often after rain, which is when most homeowners first notice them. Activity near the surface slows in winter as the ground cools, but colonies don’t die off. They move deeper and stay active. That means it’s worth treating whenever you find a problem rather than waiting for warmer weather.
What Affects the Cost of Termite Treatment?
Every home is different, so the cost of termite treatment in Pittsburgh depends on several factors. These include the size and perimeter of the foundation, the amount of concrete that needs drilling, whether there’s a crawlspace or block wall voids, how widespread the activity is, and whether you choose liquid treatment, bait stations, or both. Accessibility also counts, since finished basements, attached porches, and tight hillside lots can add time and labor. A professional inspection is the only reliable way to get an accurate quote for your specific home.
What Should You Ask Before Hiring a Termite Company?
Before you sign anything, ask which treatment method they recommend and why it fits your house. Find out which areas will be treated, whether they’ll drill through slabs or porches, and how long the work will take. Ask what the guarantee covers and how long it lasts. Stewart backs its termite treatments with a one-year guarantee, so be sure to ask what that covers for your home. Finally, ask about follow-up inspections, especially if bait stations are part of the plan.
On your end, a few simple steps help: clear access to basement walls and crawlspace entrances, move firewood and stored items away from the foundation, and point out any spots where you’ve seen mud tubes, damaged wood, or swarmers.
Frequently Asked Questions About Termite Treatment
Is liquid termite treatment safe for my family and pets?
When licensed professionals apply it according to label directions, liquid treatment goes into the soil and beneath concrete, not into living spaces. Your technician will let you know about any precautions, such as keeping pets away from treated soil until it dries.
How long does it take for bait stations to work?
Bait stations act slowly on purpose so termites can spread the bait through the colony. Depending on colony size and the season, elimination can take weeks to several months, with regular monitoring the whole time.
Can I treat termites myself?
Store-bought products rarely reach the hidden areas where subterranean termites travel, such as wall voids and the soil beneath slabs. Professional treatment uses specialized equipment and products designed to protect the entire structure.
