Anyone in Port St. Lucie 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. Winters around Port St. Lucie stay mild, with average lows near 54°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

A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.How treatment works on a typical Port St. Lucie home.
Lucie, on a slab, the crew treats the soil along the outside walls. 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. Across Port St.
Which termites live around Port St. Lucie.
Look for tiny piles of pellets that look like coarse sand. The termite you're most likely to meet in Port St. Lucie is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Formosan termites are established in Florida too. They arrived through Gulf Coast ports. Their colonies are much bigger than native ones. They can do more damage, faster. Drywood termites are common around Port St. Lucie as well, flying straight into attic framing, eaves and furniture without any soil contact.
Sealing the gap where pipes enter the house takes away one of the easiest routes in. It won't replace treatment, but it helps.When termites swarm here.
Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves. Across Port St. Lucie, eastern subterranean termites usually swarm from February through April, typically on a warm, sunny day after rain. Formosan termites in Florida swarm later, from late April into June. Look for them on warm, humid evenings around porch lights. Drywood termites swarm on spring and summer evenings, often near lights. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house.
Where to look around your house.
Lucie 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. Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge. The same advice applies across the area, from Port St. Lucie out to West Palm Beach. Many homes in Port St.

What happens at an inspection.
A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. 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.
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.
Keep kids and pets inside while the Port St. Lucie 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. Drill holes in slabs or patios get patched afterward. 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.
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 55 inches of rain a year in Port St. Lucie, keeping that strip dry takes real grading and gutter work. Wood chips touching the siding trap the moisture termites are after.

- 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
- Extent of existing damage needing repair.
- Wells, drains, or water features limiting chemical use.
- Liquid barrier versus bait station system.
- Warranty type: retreatment only or damage repair.
- Cubic footage under the tent for fumigation.
- Amount of drilling through concrete and patios.

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
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.
