Homeowners, landlords and anyone buying or selling a house in St. Petersburg, 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. Winters around St. Petersburg stay mild, with average lows near 53°F, so colonies keep feeding all year. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.

Why it’s worth acting soon

Annual Renewal and Monitoring
$150–$400 per year
Termites do not stop foraging after a treatment, so monitoring matters. Yearly visits to a St. Petersburg home catch new tubes before they reach framing.

Liquid Soil Termiticide Barrier

Drywood termites swarm on spring and summer evenings, often near lights. Look for them on warm, humid evenings around porch lights. Formosan termites in Florida swarm later, from late April into June. Petersburg, eastern subterranean termites usually swarm from February through April, typically on a warm, sunny day after rain. Around St. Swarm season is when termites show themselves.
Where to look around your house.
Petersburg out to Clearwater and Tampa. The same advice applies across the area, from St. Keep soil and mulch below the slab edge. Outside, watch for mud tubes behind shrubs.

Around St. Petersburg, expect it from February through April. Check windowsills and light fixtures for wings.
What happens at an inspection.
Photos help. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. On a slab, they focus on joints, cracks and pipe gaps. 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.
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.
Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the St. Petersburg crew applies the product, and ask how long to stay off treated soil. In Florida, formosan swarms early April–late June shortly after sunset, peaking in May (UF/IFAS); FDACS gives evenings April–July. Asian subterranean swarms have been recorded in March. Drywood swarmers fly in daytime in summer and fall. In Florida, formosan swarms early April–late June shortly after sunset, peaking in May (UF/IFAS); FDACS gives evenings April–July. Asian subterranean swarms have been recorded in March. Drywood swarmers fly in daytime in summer and fall. Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations.
Mulch and termites.
Wood chips touching the siding trap the moisture termites are after. A dry gap along the house makes mud tubes easier to spot; in St. Petersburg that means extending downspouts and pulling mulch back from the slab. Pull mulch back from the foundation and keep the layer thin.
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
- Linear feet of foundation to be treated.
- Slab, crawl space, or basement construction.
- Extent of existing damage needing repair.
- Number of bait stations required.
- Annual renewal and monitoring fees.
- Access to crawl spaces and attics.

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.

- Keep the termite renewal contract current after treatment.
- Set deck and porch posts on concrete, not soil.
- Never leave form boards or scrap lumber in the soil.
- Caulk gaps around plumbing and utility penetrations.
- Use borate-treated or pressure-treated lumber for repairs.

Questions people ask
Does fumigation kill subterranean termites too?
Not reliably. Tenting clears termites inside the house. It doesn't reach a colony living in the soil.
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
What does a WDI report include?
It lists any termites or damage found. It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach.
How long do termite bait stations take to work?
Usually several weeks to a few months. Termites have to find the stations first. Then the bait spreads through the colony.
What is the difference between subterranean and drywood termites?
Subterranean termites live in soil and build mud tubes. Drywood termites live inside the wood and leave tiny pellets. Both turn up around St. Petersburg.
Is termite prevention cheaper than repairing termite damage?
Around St. Petersburg, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around St. Petersburg, 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 Florida?
Around St. Petersburg, the usual culprit is the eastern subterranean termite.
