Anyone in Alpharetta 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. Average winter lows near 32°F slow termites near the surface around Alpharetta, 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.
- 1Dry hexagonal pellets under window frames or eaves.
- 2Mud in cracks of subfloor or joists.
- 3Doors and windows that suddenly stick.
- 4Crumbling baseboards behind furniture.
- 5Small kick-out holes in exposed wood.
- 6Discarded wings caught in spider webs.
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
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Instead of a chemical barrier, baiting in Alpharetta removes the colony itself. Stations are checked on a schedule, commonly quarterly, and refilled.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A soil barrier stops termites from reaching wood through the ground. For most Alpharetta homes with active subterranean termites, this is the fastest way to end feeding.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Annual Renewal and Monitoring
$150–$400 per year
Some Alpharetta homeowners drop the renewal after a quiet year or two. That usually voids the warranty and leaves the barrier untested.

Local termites conditions in Alpharetta.
An inspection in Alpharetta usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Alpharetta'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 Alpharetta and Georgia 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. Alpharetta 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. For Alpharetta 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 Alpharetta homes, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain.
Where to look around your house.
Check the piers, the sill plate and the floor joists. Standing water or a musty smell needs fixing either way. The same advice applies across the area, from Alpharetta out to Roswell and Johns Creek. A lot of houses around Alpharetta are built over crawl spaces, and that's usually where termites start. Take a flashlight underneath.
A year of termites in Alpharetta.
- Fall: with about 54 inches of rain a year in Alpharetta, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 89°F in Alpharetta, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Spring: swarm season. For Alpharetta homes, expect it from March through May. Check windowsills and light fixtures for wings. - Winter: a good time to book an inspection in Alpharetta, 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 also go into the crawl space.
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
- Number of bait stations required.
- Cubic footage under the tent for fumigation.
- Time of year and how booked up local companies are.
- Extent of existing damage needing repair.
- Slab, crawl space, or basement construction.
- Amount of drilling through concrete and patios.

What's your biggest concern about termites?
When to call for help
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. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
What you can do yourself
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. 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.

Questions people ask
Does fumigation kill subterranean termites too?
It doesn't reach a colony living in the soil. Tenting clears termites inside the house. Not reliably.
What does a WDI report include?
It only covers areas the inspector could reach. It also notes conditions that invite them, like wood touching soil. It lists any termites or damage found.
What time of year do termites swarm?
For Alpharetta homes, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain.
Will termites come back after treatment?
That's what yearly inspections and renewal plans are for. Treatments wear down and new colonies move in. They can.
Do I have to leave my house during termite treatment?
Everyone leaves for two to three days, pets and houseplants included. Fumigation is different. Not for a soil treatment or bait stations.
What are the signs of termites that homeowners miss?
For Alpharetta homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Alpharetta 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.
What is a termite renewal contract?
83% of locations in PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations) offered annual renewals.
Are termites common in Georgia?
Around Alpharetta, the usual culprit is the eastern subterranean termite.
