Tyler Brooks: Welcome back to the Texas Current Podcast. I'm Tyler Brooks.

Maddie Lawson: And I'm Maddie Lawson. Great to be here for our final part, Tyler.

Tyler Brooks: It is so great to finally wrap this up! Because, yeah, today's Part 3. This is the final episode of our whole three-part series focusing on Central Texas property pests.

Maddie Lawson: We made it! And honestly, Tyler, I think this is the most critical episode for a lot of our listeners.

Tyler Brooks: Oh, completely. Because we are totally shifting the tone today, right? Like, Parts 1 and 2, we spent all our time talking about the physical injuries.

Maddie Lawson: Right. The biters, the stingers, the things that send you to urgent care.

Tyler Brooks: Exactly. But for you listening right now, the posture of this episode is completely different. Especially if you own a home, or you're trying to buy one, or, you know, you're just trying to maintain this property you've poured your life savings into.

Maddie Lawson: Right. The central question for you today isn't, "Will this hurt me?"

Tyler Brooks: No, not at all.

Maddie Lawson: The question is, "Will this cost me $30,000, and will the inspector find it?"

Tyler Brooks: Yeah, which is a terrifying question! But here's the good news, right out of the gate: Nothing in this episode will sting you. All of it can show up on an inspection report.

Maddie Lawson: Exactly.

Tyler Brooks: So we are moving immediately from the financial stakes of homeownership straight to the ultimate hidden cost. Maddie, tell us about the insect that is just, you know, responsible for billions in annual hidden damage.

Maddie Lawson: We are jumping right into subterranean termites.

Tyler Brooks: The big one.

Maddie Lawson: The absolute biggest one. And they lead this list for a very specific reason: because they are the most destructive insect pests of wood in the U.S.

Tyler Brooks: Just sweeping the whole country.

Maddie Lawson: Right. And it's all because of how they operate. They are a financial nightmare because they do all of this—this incredible damage—entirely out of sight.

Tyler Brooks: Which is so frustrating. Because as a homeowner, you want to see the problem.

Maddie Lawson: Right! You want a puddle on the floor so you know the pipe is broken.

Tyler Brooks: Exactly. But with these guys, the scariest thing in this whole series isn't 8 inches long with a red head—it's a quarter-inch long, it's already inside the wall, and you will never see it.

Maddie Lawson: And you have to understand why they're in your wall in the first place, Tyler.

Tyler Brooks: Right. They aren't just there to ruin my day.

Maddie Lawson: Exactly. In nature, subterranean termites are actually incredibly beneficial.

Tyler Brooks: Beneficial?

Maddie Lawson: Yeah! They are basically nature's ultimate recyclers. Their whole biological purpose is to find dead wood, break it down, and turn it into nutrient-rich humus for the soil.

Tyler Brooks: Okay, so they're just doing their job.

Maddie Lawson: Exactly. The problem is just that, well, we decided to build our homes out of their favorite food.

Tyler Brooks: Right! We took all this dead wood, framed up a house, and basically built a five-star restaurant right on top of their ecosystem.

Maddie Lawson: We absolutely did! But, for you listening, we should probably clarify the geography a bit, because not all termites are exactly the same.

Tyler Brooks: Good point. So what are we actually dealing with here in Central Texas?

Maddie Lawson: So, listeners in Central Texas primarily deal with native subterranean termites. The scientific name is Reticulitermes.

Tyler Brooks: Reticulitermes, got it.

Maddie Lawson: And they are naturally found all over the region. They are the baseline threat that everyone needs to understand.

Tyler Brooks: Okay, but what about the other one? 'Cause I always see those panic-inducing news reports about... the Formosan termite?

Maddie Lawson: Oh, Coptotermes formosanus.

Tyler Brooks: Yeah, they make it sound like this unstoppable superbug that's gonna eat your house in a week.

Maddie Lawson: Well, to be fair, they are incredibly aggressive. A single Formosan colony can become massive, you know, exceeding over a million insects.

Tyler Brooks: Over a million... in one colony.

Maddie Lawson: Yes. And unlike the native ones that stay mostly tied to the ground, Formosans will actually build these aerial nests directly inside the wall voids of a building.

Tyler Brooks: Oh, wow. That is terrifying.

Maddie Lawson: But here is the good news for Central Texas: Formosans are mostly concentrated near the coast.

Tyler Brooks: Okay, so like Houston.

Maddie Lawson: Right, Houston, Galveston, over to Beaumont. They need that high coastal humidity.

Tyler Brooks: So if I'm sitting in Austin or San Antonio, I don't need to panic about Formosans.

Maddie Lawson: Usually no. They only really reach Central Texas if they hitch a ride.

Tyler Brooks: Hitch a ride on what? Like people's cars?

Maddie Lawson: No, usually in transported landscaping lumber—like reclaimed railroad ties or heavy retaining wall wood that gets trucked in from the coast.

Tyler Brooks: Okay, so if I'm bringing in a bunch of old coastal wood for my garden, I need to be careful.

Maddie Lawson: Exactly.

Tyler Brooks: Okay, so let's get into the teachable moment here. Because you mentioned they stay hidden, but people do see them sometimes, right? Like in the spring?

Maddie Lawson: Yes! The swarmers. This is the classic homeowner panic moment.

Tyler Brooks: Oh, yeah. It rains in April, you walk out to the kitchen, and there's just a cloud of winged bugs around the window.

Maddie Lawson: And everybody instantly tells themselves, "Oh, it's fine, those are just flying ants."

Tyler Brooks: Denial is a powerful thing, Maddie.

Maddie Lawson: It really is. But for you listening, we need to break down the 60-second identification rule. Because knowing the difference between a flying ant and a termite swarmer is critical.

Tyler Brooks: Okay, walk me through it. I'm staring at this bug on my window sill. What's the first thing I look at?

Maddie Lawson: You look at the antennae. A termite's antennae are perfectly straight—they look like a tiny little string of beads.

Tyler Brooks: Straight beads. Okay. And an ant?

Maddie Lawson: An ant's antennae are elbowed. They have a very sharp, distinct bend in them.

Tyler Brooks: Okay, so straight versus bent. What's next?

Maddie Lawson: Next is the waist. Termites have a very broad waist. Their body is basically one thick, continuous segment.

Tyler Brooks: Like a little tube.

Maddie Lawson: Yeah. But ants have that classic, sharply pinched waist.

Tyler Brooks: Right, they look like they're wearing a little corset.

Maddie Lawson: Exactly. And the third thing—and this is the absolute giveaway—is the wings.

Tyler Brooks: Okay, both of them have wings, right?

Maddie Lawson: Both have four wings. But a termite's wings are all four the exact same length. They stack perfectly on top of each other.

Tyler Brooks: And the ant?

Maddie Lawson: An ant's forewings—the front ones—are noticeably longer than the hind wings.

Tyler Brooks: So if I'm looking at a bug with, like, straight antennae, a thick waist, and equal-length wings...

Maddie Lawson: You have termites, Tyler!

Tyler Brooks: Yeah, that's what I was afraid of. But what if I just find the wings? Because I've seen that before—just a pile of clear wings on the window sill.

Maddie Lawson: That is actually the most classic first warning sign. When they swarm, they drop their wings almost immediately to mate and try to start a new colony.

Tyler Brooks: So a pile of wings means they're already moving in.

Maddie Lawson: Yes. And here is a pro-tip for you: If you find swarmers, don't just smash them or put them in a dry plastic bag.

Tyler Brooks: Why?

Maddie Lawson: Because they dry out and shatter. If you want a pest identifier to confirm what they are, you need to preserve the swarmers in 70% alcohol.

Tyler Brooks: Wait, really? Like rubbing alcohol?

Maddie Lawson: Yes! It keeps their tissues intact and prevents those fragile wings from breaking off.

Tyler Brooks: That makes total sense. So, okay, I find the wings, I put the bug in alcohol, and I call the inspector. What is the inspector actually looking for when they show up?

Maddie Lawson: They are looking for how the termites are getting from the dirt into your house. So they look for foundation shelter tubes.

Tyler Brooks: Like mud tubes.

Maddie Lawson: Exactly. They build these little dirt highways up the side of your concrete foundation so they don't dry out in the air.

Tyler Brooks: Okay, so they check the outside. What about the inside? They can't see through drywall.

Maddie Lawson: No, but they use moisture meters. Termites bring a lot of moisture up from the soil into the walls.

Tyler Brooks: Oh, so the meter can just scan the wall and find a wet spot.

Maddie Lawson: Right. It flags hidden nests inside the house. They also aggressively check for any wood-to-soil contact around the exterior.

Tyler Brooks: Which we will definitely get into. But Maddie, I want to ask you a pointed question here about treatments.

Maddie Lawson: Okay, go for it.

Tyler Brooks: Because I've looked at the regulations. If I have termites, and I hire a company, they always call it a "partial treatment" on the paperwork.

Maddie Lawson: Yes, they do.

Tyler Brooks: If I am paying thousands of dollars, I don't want a partial anything! Is this just a pest control ripoff? Why won't they just do a full treatment?

Maddie Lawson: It's not a ripoff, Tyler. It's actually an unavoidable structural reality.

Tyler Brooks: How so?

Maddie Lawson: In Texas, doing a perimeter treatment around the outside of your foundation, or foaming the plumbing penetrations—that is legally defined as a partial treatment.

Tyler Brooks: Even if they do it perfectly?

Maddie Lawson: Even if it's flawless! Because the only true full treatment happens pre-construction, before the foundation is even poured, when they can spray the entire footprint of bare dirt.

Tyler Brooks: Oh, right! Because once the concrete slab is poured, you can't get to the dirt underneath the middle of my living room.

Maddie Lawson: Exactly—unless they drill holes through all your flooring, which nobody wants.

Tyler Brooks: Right, so it's always partial. Wow. Okay, so that is the pest you never see doing all this invisible damage. Let's pivot to a pest you wish you couldn't see, but you absolutely do: the transplant panic.

Maddie Lawson: It really is a rite of passage!

Tyler Brooks: It is! I mean, every person who moves here from Ohio has the exact same August.

Maddie Lawson: They really do.

Tyler Brooks: They're standing in the kitchen at midnight, getting a glass of water, and suddenly something the size of an AA battery flies past their face, and they just immediately call their mother.

Maddie Lawson: It's terrifying if you aren't used to it! We are talking about tree roaches—specifically the American cockroach and the Smoky Brown cockroach.

Tyler Brooks: They are huge!

Maddie Lawson: They are. The American roach is about an inch and a half to 2 inches long, reddish-brown. Smoky Browns are a glossy mahogany color, and they are incredibly strong fliers.

Tyler Brooks: And they just show up inside to ruin my night.

Maddie Lawson: Well, let's reframe this for the listeners. Because these two species... they actually live outdoors!

Tyler Brooks: Wait, they don't live in the walls?

Maddie Lawson: No! They live in your mulch, in the gutters, up in the trees. They usually only wander inside because it's super hot and dry outside, and they are desperately looking for water.

Tyler Brooks: Okay, we have to firmly distinguish this, though. Because if I see a giant roach, my first instinct is that my house is infested and I need an exterminator immediately.

Maddie Lawson: And that is the crucial contrast here. You are thinking of German cockroaches.

Tyler Brooks: Right, the little ones.

Maddie Lawson: Yes. German cockroaches are small, tan, and have two dark stripes. They breed entirely indoors. If you have German roaches, you absolutely need professional extermination.

Tyler Brooks: But the big, flying tree roaches...

Maddie Lawson: The big ones are an entirely different thing. I want to explicitly reassure you listening right now: A massive tree roach flying at your porch light and getting inside is not a reflection of poor housekeeping.

Tyler Brooks: So wait, if I see one of these monsters, I shouldn't go buy a bunch of toxic roach bombs and set them off in the kitchen?

Maddie Lawson: Please do not do that!

Tyler Brooks: I just need to go to the hardware store and buy some door weatherstripping?

Maddie Lawson: Yes! It is almost always a weatherstripping or a door gap issue. They just squeeze their way in under the door or through a loose window screen.

Tyler Brooks: That makes me feel so much better. It's just a mechanical failure of the house, not a permanent infestation.

Maddie Lawson: Exactly! Which, honestly, leads perfectly into what we really need to talk about next.

Tyler Brooks: The prevention checklist.

Maddie Lawson: Right! Because knowing these bugs exist is completely useless unless you know how to block them from entering your home.

Tyler Brooks: And how to spot them if you're in the middle of a real estate transaction. So let's run through these structural rules. For the listeners maintaining their homes, what's Step 1?

Maddie Lawson: Step 1—and this is non-negotiable—break all wood-to-soil contact.

Tyler Brooks: So no wood touching the dirt.

Maddie Lawson: Zero. Whether it's your deck framing, landscaping timbers, or a pile of firewood. If it touches the ground, it's a direct bridge for termites to enter your house without building those mud tubes.

Tyler Brooks: Got it. Keep the wood off the dirt. What's next?

Maddie Lawson: You have to grade the soil away from your foundation.

Tyler Brooks: So the ground slopes away from the house.

Maddie Lawson: Right. Because if water pools against your foundation, you're just creating a permanent hydration station for termites.

Tyler Brooks: And probably a nice, humid spa for those tree roaches, too.

Maddie Lawson: Oh, absolutely! Which brings us to the next point: Watch your mulch lines.

Tyler Brooks: People love their mulch.

Maddie Lawson: They do, but deep mulch piled right against the brick is a huge harborage area for roaches, and it holds so much moisture. Keep it pulled back a bit.

Tyler Brooks: Okay, so keep the mulch thin and away from the brick. What else?

Maddie Lawson: Clean your gutters!

Tyler Brooks: Really? For bugs?

Maddie Lawson: Smoky Brown roaches love living in wet, rotting leaf litter. If your gutters are clogged, you essentially have a roach motel attached to your roof.

Tyler Brooks: Oh, that's disgusting. Okay, clean the gutters.

Maddie Lawson: Next, seal your door gaps and check the weep holes in your brick siding.

Tyler Brooks: Just to mechanically keep the wanderers out.

Maddie Lawson: Exactly. And the last one is a really simple trick: Switch your exterior lighting to warm bulbs.

Tyler Brooks: Oh, like the yellow-looking ones? Why does that work?

Maddie Lawson: Because nocturnal insects—including termite swarmers and flying tree roaches—are highly attracted to the UV spectrum in bright white or blue lights. Warm bulbs emit way less UV, so you avoid attracting them to your porch in the first place.

Tyler Brooks: That is brilliant! Just change a lightbulb. Okay, so that's the homeowner maintenance side. But Maddie, what about the WDI reports?

Maddie Lawson: The Wood-Destroying Insect report. This is critical for anyone buying a home.

Tyler Brooks: Okay, let me ask a practical, skeptical question here on behalf of basically every homebuyer ever.

Maddie Lawson: Let's hear it.

Tyler Brooks: If I am buying a house, right, and I'm already paying a premium for a top-tier general home inspector—he's up in the attic, he's checking the breaker box—why do I need to shell out extra money for a totally separate WDI report? Can't the regular guy just tell me if the house is being eaten?

Maddie Lawson: It's a fair question, but no, he cannot. A general home inspection is entirely separate from a WDI inspection. Because a general inspector is looking at mechanical and safety issues. They aren't trained, and often aren't legally allowed, to probe for the specific signs of a Section 1 pest infestation.

Tyler Brooks: What is Section 1?

Maddie Lawson: That's the category for active wood-destroying insects like termites. Only a licensed WDI inspector is going to use the specialized moisture meters, check the hidden mud tubes, and definitively tell you if the structural framing is compromised.

Tyler Brooks: So the regular guy might see a water stain and say, "Hey, your window leaked," but the WDI guy says, "No, that's a termite nest."

Maddie Lawson: Exactly! Only the WDI catches these pests before they cause a structural collapse. You cannot skip it.

Tyler Brooks: Wow. Okay, message received. Well, Maddie, this has been an incredible series.

Maddie Lawson: It really has. And, you know, Tyler, I want to leave the listener with a broader, philosophical takeaway here.

Tyler Brooks: Oh, getting deep! Let's do it.

Maddie Lawson: It's just about our relationship with nature. We spend so much time fighting these pests, but think about it: Termites have been flawlessly executing their job—recycling dead wood into nutrient-rich soil—for a hundred million years.

Tyler Brooks: They're just doing what they've always done.

Maddie Lawson: Right! They aren't villains. It's just a wild thought that we simply decided to build our most expensive assets out of their natural food source.

Tyler Brooks: Yeah, we literally build houses out of termite food!

Maddie Lawson: Exactly! And then we plop those assets right down into their ecosystem. The pests aren't really invading our space—we built a buffet in theirs.

Tyler Brooks: We built a buffet in theirs! That is such a profound way to look at it. We really did just set up an all-you-can-eat wood buffet in the middle of the forest.

Maddie Lawson: We did!

Tyler Brooks: Well, before we wrap up completely, I want to give a very warm thank you to our generous sponsors who make this show possible. We couldn't do this without your support.

Maddie Lawson: Absolutely. Thank you to our sponsors.

Tyler Brooks: And thank you, the listener, for tuning in to the three-part series of the Texas Current Podcast. We really hope this information helps you protect your home and, honestly, just sleep a little better at night.

Maddie Lawson: Yes! Thank you all so much for listening.
