Termite Control in Media and Delaware County, PA

What are the signs of subterranean termites?

Eastern subterranean termites live in the soil and reach wood through mud tubes about the width of a pencil. Most homeowners never see a worker termite. They notice what the colony leaves behind:

Timing helps you read the signs. Around here, swarms usually come on warm spring days after rain, most often from March into May, and winged termites coming out of a basement wall mean the colony is feeding in or under the house, not just somewhere in the yard.

• Mud tubes running up foundation walls, piers, sill plates or the underside of porch steps
• Small dark insects with long, pale wings swarming near basement windows or doors on a warm spring day
• Piles of shed wings on windowsills, in cobwebs or on the basement floor
• Wood that sounds hollow or crumbles under a screwdriver, with layered galleries packed with soil
• Rippled paint or baseboards that look water-damaged even though they're dry
• A soft spot where the wooden sill rests on an old stone foundation

Why termites are a real risk for Delaware County homes

Southeastern Pennsylvania lies in a moderate-to-heavy subterranean termite zone, and local housing gives colonies plenty of ways in. In eastern Delaware County, Census (ACS) estimates put the median home in Lansdowne at 1943 and in Upper Darby at 1948. Many of those twins sit on fieldstone foundations whose mortar has softened with age, and termites tunnel through those joints without leaving a tube you can see.

Front porches on pre-war twins are often concrete slabs poured over fill soil that touches the house framing, a classic hidden entry. Wooden cellar window frames and firewood stacked against the wall add more chances.

Newer homes are not exempt. In the 1990s subdivisions of Concord and Bethel townships and across Chester County, the weak spots shift to slab garages, plumbing penetrations through the slab, foam insulation below grade and deep mulch beds piled against the siding. Termites can travel behind foam board and siding where nobody looks.

How we inspect before recommending termite treatment

A termite inspection comes first because the treatment has to match what's actually there. We walk the outside of the foundation, check porches, stoops and garage slabs, then work through the basement or crawl space looking at sills, rim joists and any wood touching soil. Suspect wood gets sounded and probed, and moisture is checked where the job calls for it.

Ruling out look-alikes is part of the job. Large black ants trailing out of a window frame point toward carpenter ant control, while pinhole exits and flour-fine powder under old beams suggest the need for powderpost beetle treatment. Buying or selling a house? A WDI inspection report is a separate document with its own form and rules.

Termite treatment options in PA: liquid barrier or bait stations?

Existing houses are usually protected one of two ways, and some properties use both. A liquid termite treatment places a non-repellent termiticide in the soil along the foundation so foraging termites pick it up and spread it. Termite bait stations go into the ground around the house and hold bait that workers carry back to the colony.

Building an addition or a new house? Pre-construction termite treatment protects the soil before the slab is poured. Not every method is offered on every property, so ask us on the call which options are available for yours.

What a termite control visit looks like

1. 1

   Tell us what you saw

   Call and describe where the swarmers, tubes or damage showed up. A photo or an insect saved in a sealed bag helps with identification.

2. 2

   Free inspection

   Thom or one of his team checks the foundation, basement or crawl space, porches and yard edge, and confirms which insect is involved.

3. 3

   Written quote

   You receive a written quote naming the recommended method, the areas involved and any prep, before work begins.

4. 4

   Prep the house

   Pull stored boxes about two feet back from basement walls, clear porch slabs and let us know about any well, sump pit or buried utility lines.

5. 5

   Treatment

   The work follows the plan in your quote, whether that means soil treatment, station installation or targeted work on a look-alike pest.

6. 6

   Follow-up plan

   We explain the monitoring or re-inspection your method calls for and what to watch for when the next swarm season arrives.

How long until the termites are gone, and what happens after?

A soil treatment starts working as soon as termites move through the treated zone, though a few workers or even a swarm can still appear for some weeks while the colony declines. Baiting is slower: termites first have to find the stations, then feed long enough to carry bait home, which can take months and slows in cold weather.

Expect small patches where slabs were drilled, and plan to watch the house through the next spring. Damaged framing doesn't recover on its own; once activity is under control, a carpenter can sister or replace joists and sills that lost strength.

Pennsylvania rules behind termite treatment and home-sale reports

Termiticides are controlled by their labels and by state law. In Pennsylvania, soil treatment for hire falls under the Pesticide Control Act of 1973, enforced by the Pennsylvania Department of Agriculture (PDA), which licenses pest control businesses and certifies applicators, and 7 Pa. Code § 128.31 puts the business license number on company vehicles. Labels also set distances from wells and cisterns and limit treatment near water, which is why we ask about a well or sump before quoting.

Home sales add a separate paper trail. Lenders, often on FHA or VA loans, may require a wood-destroying insect report, commonly written on the NPMA-33 form, and that report has to come from a properly licensed inspector.

What shapes termite treatment cost

We don't price termite work over the phone because every house is different. Your written quote reflects:

Older eastern Delaware County houses usually take more labor per foot. A fieldstone foundation under a Lansdowne twin or a hollow-block wall in a 1950s Ridley Township home may need drilling and void treatment on top of trenching, while poured concrete in a newer Edgmont subdivision is simpler to treat from the outside.

Attached homes add one more variable. A barrier around your half of a twin protects your side, so the quote notes whether the shared foundation line can be reached from your property or needs the neighbor's cooperation.

• Linear feet of foundation, plus the number of porches, stoops and attached garages
• Foundation type: fieldstone, hollow block, poured concrete or slab
• How much drilling a finished basement, patio or garage slab requires
• Soil treatment, bait stations or a combination
• Wells, cisterns, creeks or drainage that limit where soil can be treated
• Any ongoing monitoring the method requires
• Whether carpenter ants or wood-boring beetles also need attention

Preventing termites from coming back

Keep mulch thin and pulled several inches back from the foundation, and leave a visible band of concrete or stone between soil and siding. Store firewood and scrap lumber off the ground and away from the house. Correct downspouts and grading that send water toward the walls, and make sure air conditioner condensate drains away from the foundation.

Look over basement walls and porch steps each spring when swarms begin. Termites are only one part of keeping a house pest-free; for mice, ants and seasonal invaders, see our general pest control services and insect control.
