Let’s be real, there’s something super charming about an older Phoenix home. The original tile, the mid-century details, maybe a creaky wood floor that somehow adds personality instead of just making noise. Whether you’re living in an Arcadia ranch or eyeing a gem in the Garfield Historic District, these homes have character. That’s right, pest risks in older Phoenix homes are real.
But, they also have cracks. And not just the “cute vintage charm” kind. I’m talking about cracks that let in termites, scorpions, roof rats, and a whole squad of desert critters who’d love to move in with you.
Let’s discuss what you need to watch out for, how to tell if your place has a problem, and what to do before those tiny invaders cause expensive damage.
Why Older Homes in Phoenix Attract More Pests
If your home was built before 1990, chances are it’s got a few quirks—and, unfortunately, a few pest magnets.
Here’s why older homes in Phoenix are more likely to have pest issues:
- Aging materials: Older wood structures are more vulnerable to termites. Some building materials used decades ago are now considered pest-friendly, especially if they’ve never been treated.
- Cracks and gaps: Time causes shifting foundations, weathered seals, and tiny openings in the walls, eaves, and baseboards—perfect for insects and rodents to slip through.
- Vintage plumbing: Older pipes and drainage systems create hidden moisture that attracts pests like termites, ants, and cockroaches.
- Mature landscaping: Those tall trees and dense bushes around the house? Roof rats and scorpions love them.
Basically, your home’s age might make it charming, but it also makes it prime real estate for pests.
Common Pests Found in Older Phoenix Homes
Let’s break down the usual suspects and what they’re after in your charming old house.
Termites
If you’ve lived in Phoenix for more than five minutes, you’ve probably heard the word termite. And for good reason.
These guys are silent destroyers. They love older, untreated wood and can go undetected for years while quietly munching away at your home’s structure.
What makes it worse?
In older homes, signs like warped wood or flaking paint often get chalked up to age, not pests, until it’s too late.
Scorpions
Look, we don’t want to freak you out, but Phoenix is basically Scorpion Central. Older homes with cool, dark crawl spaces or garages are prime hiding spots for bark scorpions, especially if your home backs up to desert areas or has overgrown landscaping.
Fun fact: Scorpions can squeeze through cracks as small as a credit card’s thickness.
Yikes, right?
Roof Rats
They sound cute. They’re not.
Roof rats often climb onto roofs via overhanging trees (classic in older neighborhoods) and enter attics through vents or tiny gaps in the eaves. Once inside, they chew wiring, nest in insulation, and generally wreak havoc.
Cockroaches and Ants
Classic home invaders. In older Phoenix homes, they often enter through:
- Unsealed plumbing gaps
- Cracked grout in the kitchen or bathrooms
- Floorboards that don’t quite meet anymore
Cockroaches especially love older sewer systems and pipes. If you’ve got plumbing from the ‘70s, be warned.
Signs Your Older Home Has a Pest Problem
A lot of pests don’t make themselves known until they’ve already done damage. But there are some early signs to keep an eye (and ear) out for:
- Hollow-sounding walls or wood
- Droppings or strange odors (rat urine has a musky smell that’s hard to miss)
- Mud tubes along baseboards or foundation (hello termites)
- Scratchy sounds at night (rats and mice in the attic)
- Live pest sightings, especially during the day
If you’re seeing one pest, there’s probably more where that came from.
Why DIY Isn’t Enough for Older Homes
I get it. DIY pest sprays are easy to grab at the store. But for older Phoenix homes, that’s just not gonna cut it.
Here’s why:
- Pests in old homes often hide in places you can’t reach: inside walls, under floors, or behind vintage built-ins.
- DIY sprays don’t stop infestations. They might kill a few bugs but not the nest.
- You could miss structural damage caused by termites or rats.
You need an experienced eye. A licensed Phoenix pest control pro can detect problems you’d never notice until it’s too late.
What to Do If You Suspect an Infestation
First things first—don’t panic. These issues are super common in Phoenix, especially in historic homes. But do act fast.
- Call a licensed pest control company. Ask specifically for experience with older homes and desert pests.
- Get a full inspection. They’ll check the attic, foundation, crawl spaces, walls, you name it.
- Request a treatment plan. Make sure it includes monitoring and follow-up visits.
- Ask about damage repair. Some companies handle this or partner with contractors.
The longer you wait, the more damage those pests can do.

How One Couple Saved Their Arcadia Home from Termites
Let’s call them Mike and Jenny. They bought a 1950s ranch in Arcadia and loved it: big yard, exposed beams, and that cool retro kitchen. A month after moving in, they noticed a weird pile of sawdust in the laundry room.
Turns out, termites had eaten through part of a support beam under the floor. Repairs cost over $6,000, and it could’ve been way worse if they’d waited.
Now? They swear by annual inspections.
Moral of the story: Don’t skip the check just because you love the house.

Frequently Asked Questions
1. Why are older homes in Phoenix more vulnerable to pests?
Older homes often have aging materials, cracks, and outdated construction techniques that make it easier for pests to sneak in. Plus, time causes natural wear and tear, like foundation shifts and worn-out seals—that create entry points for bugs and rodents.
2. What types of pests should I worry about in an older Phoenix home?
The most common offenders include:
- Termites (especially subterranean)
- Scorpions
- Roof rats
- Cockroaches
- Carpenter ants
- These pests are especially active in homes with wood structures, hidden crawl spaces, and older plumbing systems.
3. How can I tell if my home has termites?
Watch for:
- Mud tubes near the foundation
- Hollow-sounding wood
- Peeling paint that resembles water damage
- Tiny piles of sawdust or frass
- Swarms of winged insects, especially after rain
- If you see any of these signs, it’s time to call in a pest control pro.
4. Are scorpions really a problem in older houses?
Yes, especially bark scorpions, which are common in Phoenix. They love older homes with cracks in walls, crawl spaces, and overgrown landscaping. And yep, they can fit through an opening the width of a credit card.
5. Can pests cause actual damage to my home?
Absolutely. Termites can weaken wooden beams, roof rats chew electrical wiring and insulation, and cockroaches can contribute to health issues. Over time, these infestations can cause thousands of dollars in damage.
6. I haven’t seen pests, so I’m probably good, right?
Not necessarily. Many pests, especially termites and rats, do their dirty work quietly and out of sight. You might not see obvious signs until the damage is already done. That’s why yearly inspections are key, especially in older homes.
7. What’s the best way to pest-proof an older home?
Start with the basics:
- Seal gaps and cracks
- Install weatherstripping
- Repair leaky plumbing
- Trim trees and plants away from the house
- Schedule regular pest inspections
- Don’t rely on store-bought sprays alone, older homes need a more strategic approach.
8. Should I get a pest inspection before buying an older home in Phoenix?
Yes, 100%. Always ask for a Wood-Destroying Insect Inspection Report (WDIIR), and consider getting your own independent pest inspection. It can uncover hidden infestations or past damage that might affect your buying decision.
9. How often should I have my older home inspected for pests?
Ideally, once a year. If your home has a history of pest problems or you’re in a high-risk area (like near washes or older neighborhoods), you might even want to do it twice a year.
10. What should I do if I suspect a pest infestation?
Don’t wait. Contact a licensed pest control company in Phoenix that specializes in older homes. They can assess the situation, provide a detailed inspection, and create a custom treatment plan to stop pests in their tracks.
