- Look for mud tubes, shed wings and hollow-sounding wood.
- Swarms usually show up in spring and early summer.
- The usual fix is a soil barrier or bait stations.

- Insurance usually doesn’t cover termite damage.
Anyone in Casper who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winter lows around Casper average near 14°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Damage found during a remodel or repair.
- 2Mud in cracks of subfloor or joists.
- 3Mud tubes running up foundation walls or piers.
- 4Layered, honeycombed wood packed with soil.
- 5Live pale insects inside a broken mud tube.
- 6Dry hexagonal pellets under window frames or eaves.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.
Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
The inspector checks the foundation, garage, attic and damp spots. Bring up anything you’ve noticed.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Localized Wood, Foam, and Borate Treatment
$250–$1,500
When termites are limited to one wall or window frame, a technician can treat that wood directly, which is common when Casper subterranean termites reach a damp sill plate. Foam expands into voids, and borate soaks into bare lumber.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Annual Renewal and Monitoring
$150–$400 per year
Termites do not stop foraging after a treatment, so monitoring matters. Yearly visits to a Casper home catch new tubes before they reach framing.
- Time
- 30–60 minutes per visit
- Best for
- Keeping a treated home protected after the initial job
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)
Tenting is mainly for drywood termites. Most homes here never need it.
- Time
- 2–3 days including tenting and aeration
- Best for
- Widespread drywood termites throughout a structure

Local termites conditions in Casper.
An inspection in Casper usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Casper's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Casper and Wyoming every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Casper sits in a semi-arid continental climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. For Casper homes, the area is mostly suburban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by.
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.
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. Swarm season is when termites show themselves. For Casper homes, arid-land subterranean termites usually swarm in spring and early summer, often on a warm day after rain.
Where to look around your house.
Outside, check porches, steps and decks that touch soil. Wood should stay several inches above the ground. Plenty of homes in Casper have basements, so check where the wood framing sits on top of the foundation wall. Look around window wells and unfinished walls.
A year of termites in Casper.
- Fall: with about 12 inches of rain a year in Casper, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 88°F in Casper, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Spring: swarm season in Casper, often on a warm day after rain. Check windowsills for wings. - Winter: a good time to book an inspection in Casper, before swarm season starts.
What happens at an inspection.
Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two. Photos help. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. They'll check the basement walls and sill plate.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - 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.
Getting ready for treatment day.
Mark sprinkler heads and any buried lines. Move stored boxes away from garage walls. Clear a path along the outside walls. Soil treatments and bait stations need little prep. Any drill holes in a slab or patio get patched. Ask how long to stay off treated soil. Keep pets and kids inside while the crew works outside.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- What product or system will you use? - Is the whole foundation treated, or just one spot? - 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 affects the price
- Annual renewal and monitoring fees.
- Number of bait stations required.
- Liquid barrier versus bait station system.
- Whole-house fumigation versus spot treatment.
- Warranty type: retreatment only or damage repair.
- Attached garages, decks, and additions.

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
Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see. Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house.

For Casper 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. For Casper homes, most of the housing is suburban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Casper has a semi-arid continental climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. A typical home in Casper is worth around $275k, which puts a few hundred dollars for an inspection and prevention in perspective. With summer highs around 88°F, Casper's semi-arid continental climate decides when local termites are busiest. Low isn't zero, though. Wyoming is on the low end for termites.

Questions people ask
Are mud tubes always a sign of active termites?
If it's rebuilt, they're active. Break off a piece and check back in a week. Old tubes can stay on a wall for years. Not always.
How do I know if I have termites or flying ants?
Save one in a bag for the inspector. Ants have a pinched waist; termites don't. Termite wings are all the same length. Check the wings and the waist.
How do I choose a termite company?
Compare the proposals, not just the totals. Ask what the warranty covers. Ask which termites they found and what product they'll use. Make sure they're licensed in Wyoming.
What is the difference between subterranean and drywood termites?
Around Casper, the subterranean kind causes most problems. Drywood termites live inside the wood and leave tiny pellets. Subterranean termites live in soil and build mud tubes.
How long does termite treatment take?
Fumigation takes two to three days. Bait stations take a few hours to install. A liquid barrier takes half a day to a day.
When is termite swarming season?
For Casper homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Casper 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.
Are termites common in Wyoming?
Low isn't zero, though. Around Casper, the usual culprit is the arid-land subterranean termite.
