Homeowners, landlords and anyone buying or selling a house in Decatur, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 32°F slow termites near the surface around Decatur, but they move deeper and keep feeding under heated homes. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Sagging or spongy floors near exterior walls.
- 2Buckling laminate or warped hardwood flooring.
- 3Dry hexagonal pellets under window frames or eaves.
- 4Live pale insects inside a broken mud tube.
- 5Piles of identical shed wings on windowsills.
- 6Screwdriver sinks easily into sills or trim.
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.
- Formosan colonies are large and can do serious damage quickly.

Localized Wood, Foam, and Borate Treatment
$250–$1,500

- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
Where a slab or porch blocks the trench, the Decatur applicator drills holes and injects underneath. The goal is a continuous treated zone with no gaps.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)

Local termites conditions in Decatur.
A provider who works Decatur and Alabama 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. Knowing Decatur'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. An inspection in Decatur usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Decatur, 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. Decatur sits in a humid subtropical climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.Which termites live around Decatur.
They can do more damage, faster. Their colonies are much bigger than native ones. They arrived through Gulf Coast ports. Formosan termites are established in Alabama too. It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Decatur is the eastern subterranean termite.
When termites swarm here.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Look for them on warm, humid evenings around porch lights. Formosan termites in Alabama swarm later, from late April into June. Around Decatur, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain. Swarm season is when termites show themselves.
Where to look around your house.
The same advice applies across the area, from Decatur out to Madison and Huntsville. Standing water or a musty smell needs fixing either way. Check the piers, the sill plate and the floor joists. Take a flashlight underneath. A lot of houses around Decatur are built over crawl spaces, and that's usually where termites start.
A year of termites in Decatur.
- Spring: swarm season. Around Decatur, expect it from March through May. Check windowsills and light fixtures for wings. - Summer: with highs around 90°F in Decatur, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 53 inches of rain a year in Decatur, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Decatur, before swarm season starts.
Ways to keep the cost down.
- Book before swarm season, when schedules fill up. - If you already have a warranty, keep the renewal current. - Ask about both bait and liquid options for your house. - Fix leaks and drainage first. Moisture brings termites back. - Get two or three quotes, and compare what each one covers.
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. They'll also go into the crawl space. 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?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Prep is light for liquid treatments and bait stations. Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the Decatur crew applies the product, and ask how long to stay off treated soil. Alabama's climate lets termites be active year-round throughout most of the state (ACES); regional extension sources put native swarms in late winter–spring and Formosan swarms in evenings April–July. Drill holes in slabs or patios get patched afterward.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot, and with roughly 53 inches of rain a year in Decatur, keeping that strip dry takes real grading and gutter work. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- What do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot? - What product or system will you use? - Which termites did you find, and where?
What affects the price
- Time of year and how booked up local companies are.
- Whole-house fumigation versus spot treatment.
- Slab, crawl space, or basement construction.
- Annual renewal and monitoring fees.
- Liquid barrier versus bait station system.
- Wells, drains, or water features limiting chemical use.
- Number of bait stations required.
- Species: subterranean, drywood, or Formosan.

What's your biggest concern about termite control costs?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way.
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.
