Homeowners, landlords and anyone buying or selling a house in Norman, whether you've spotted something or just want to know what to watch for.
What to look for
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 28°F slow termites near the surface around Norman, but they move deeper and keep feeding under heated homes.

Crawl spaces are where termites usually get in. Joists, piers and the sill plate should all get a close look.How treatment works on a typical Norman home.
Under patios and garage floors, they drill small holes. Treatment goes in through the holes, which get patched afterward. Bait stations are the other main option. They're spaced every 10 to 20 feet. Termites carry the bait back to the colony. The stations are checked on a schedule, often every few months. For Norman homes, on a slab, the crew treats the soil along the outside walls.
Which termites live around Norman.
It needs steady moisture. The termite you're most likely to meet in Norman is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.When termites swarm here.
Swarm season is when termites show themselves. For Norman homes, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house. Save a few in a bag, or snap a clear photo.
Where to look around your house.
Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge. The same advice applies across the area, from Norman out to Moore and Midwest City. Many homes in Norman sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks. Check the garage edges and behind baseboards. Look where pipes come through the floor.
A year of termites in Norman.
- Fall: with about 38 inches of rain a year in Norman, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Norman, before swarm season starts. - Spring: swarm season. For Norman homes, expect it from March through May. Check windowsills and light fixtures for wings. - Summer: with highs around 93°F in Norman, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
What happens at an inspection.
Most inspections take an hour or two. The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic. On a slab, they focus on joints, cracks and pipe gaps. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help.
Termites or ants?
- Debris: termites leave mud. Carpenter ants leave sawdust. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t. - Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow.
Getting ready for treatment day.
Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched. Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls. Mark sprinkler heads and any buried lines.
Mulch and termites.
Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- What does the warranty cover, and for how long? - What does the yearly renewal cost? - What do I need to do before and after treatment? - Which termites did you find, and where? - What product or system will you use? - Is the whole foundation treated, or just one spot?
What affects the price
- Amount of drilling through concrete and patios.
- Warranty type: retreatment only or damage repair.
- Annual renewal and monitoring fees.
- Number of bait stations required.
- Attached garages, decks, and additions.
- Local labor rates and licensing requirements.

What's your biggest concern about termites?
When to call for help
Termites leave mud. Carpenter ants leave clean tunnels and sawdust. It's also the cheapest termite service. Lenders often ask for one. Get a wood-destroying insect (WDI) report either way. Buying or selling? Hollow-sounding wood is another clue. Call if you see mud tubes, pellets or an indoor swarm.
What you can do yourself
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.
Termites in Norman
A typical home in Norman is worth around $240k, which puts a few hundred dollars for an inspection and prevention in perspective. Norman has a humid subtropical climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. For Norman homes, most of the housing is urban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. For Norman homes, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Norman and Oklahoma can point out the specific conditions that matter most here before you commit to a plan. About 38 inches of rain a year in Norman is plenty for subterranean termites, especially on any side of the house kept damp by gutters or sprinklers. Termite activity in Oklahoma is above average. Most houses will see termites at some point. With summer highs around 93°F, Norman's humid subtropical climate decides when local termites are busiest.

When termites are busiest around Norman
February–June (eastern subterranean, daytime after rain). Penn State: 'In Pennsylvania, swarms of winged termites usually emerge between February and June'. NC State: native species 'begin swarming in late winter and continue into September or October', and 'Swarming usually occurs during the day, particularly on warm days following rain'. Kentucky: 'Spring typically is when large numbers of winged termites... emerge inside homes'. Ohio: 'Eastern subterranean termites swarm over spring and early summer'. Missouri: swarms 'during the spring months, usually on a warm, sunny day following rain'.

Simple ways to keep termites away
- Address wood-to-soil contact at steps, fences, and trellises.
- Caulk gaps around plumbing and utility penetrations.
- Ventilate crawl spaces and control humidity.
- Install a vapor barrier over crawl space soil.
- Extend downspouts so water drains away from walls.
- Repair rotting trim, fascia, and window frames.
In an apartment building, termites travel through shared walls and slab joints, so one unit's problem is the whole building's problem.Did you know?
Some African termite mounds stand more than 25 feet tall.
For Norman homes, termites are closer cousins to cockroaches than to ants, despite the old nickname white ants.
Questions people ask
Is termite treatment safe for kids and pets?
Bait stations are locked and buried. Ask for the label and follow any re-entry times. Used according to the label, yes. Soil treatments stay in the ground.
Do I have to leave my house during termite treatment?
Fumigation is different. Everyone leaves for two to three days, pets and houseplants included. Not for a soil treatment or bait stations.
How long does termite treatment take?
Bait stations take a few hours to install. Fumigation takes two to three days. A liquid barrier takes half a day to a day.
What is the difference between subterranean and drywood termites?
Drywood termites live inside the wood and leave tiny pellets. Around Norman, the subterranean kind causes most problems. Subterranean termites live in soil and build mud tubes.
How do I choose a termite company?
Ask what the warranty covers. Compare the proposals, not just the totals. Make sure they're licensed in Oklahoma. Ask which termites they found and what product they'll use.
How do I know if I have termites or ants?
For Norman homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Norman homes, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Can you treat for termites before building a house?
Yes, and most termite companies offer it. For Norman homes, anyone planning a build can usually find a termite pre-treatment locally: 79% of locations responding to PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations) offered it.
Are termites common in Oklahoma?
Around Norman, the usual culprit is the eastern subterranean termite.
