Subterranean termites are the most destructive wood pest in Florida — causing an estimated $1+ billion annually in US damage. Native subterranean termites are widespread; Formosan termites cause even more rapid damage. Here is the Florida guide.
How to identify subterranean termites
- 1/8 to 3/8 inch long depending on caste.
- Workers: cream-colored, soft-bodied.
- Soldiers: tan head with large brown jaws.
- Reproductive swarmers: dark with two pairs of equal-length wings.
- Often confused with flying ants — termites have straight antennae and equal wings; ants have elbowed antennae and unequal wings.
Signs of subterranean termite infestation
- Mud tubes on foundations, walls, or pipes (most common indicator).
- Discarded wings near windowsills or light fixtures after spring swarm.
- Soft, hollow-sounding wood when tapped.
- Damaged wood with mud or soil packed inside galleries.
- Sagging floors or ceilings in advanced infestations.
Florida termite season
Spring (March-May) is peak swarming season. Native subterranean termites swarm during day; Formosan termites swarm at dusk near lights.
DIY vs Professional decision
DIY makes sense if
- You see active termites in a small area only.
- Damage is limited to one localized spot.
- You can apply Taurus SC or Termidor SC perimeter treatment yourself.
Hire a pro if
- Mud tubes are throughout the structure.
- You suspect Formosan termites (faster damage).
- Damage is structural (floor joists, wall studs).
- You want a transferable warranty for home sale.
- Your home requires bait stations or fumigation.
DIY treatment with Taurus SC
Trench around foundation 4-6 inches deep, mix Taurus SC with water, pour into trench, backfill. Creates a treatment zone that worker termites traffic through and carry back to colony.
Cost reality
- DIY perimeter treatment: $200-$500 in materials.
- Professional liquid treatment: $1,200-$2,500.
- Sentricon bait system: $1,500-$3,000 install + annual monitoring fee.
- Tenting/fumigation (drywood termites only): $2,500-$5,000.
Verdict
For minor subterranean termite activity, DIY Taurus SC perimeter treatment is reasonable. For widespread infestation, suspected Formosan termites, or any structural damage, hire a Florida-licensed pest control company with termite warranty.
Reminder: Always read product labels and follow manufacturer safety instructions. For dangerous pests or large infestations, hire a licensed professional.
Keeping subterranean termites out of your Panhandle home
In the Florida Panhandle, a warm, humid climate keeps pests like subterranean termites active for much of the year, so prevention is your best defense. A few habits stop most problems before they start:
- Seal entry points — close cracks around the foundation, gaps where pipes enter, and replace worn weatherstripping and door sweeps.
- Cut the moisture — fix leaks, clear gutters, and address AC condensate; humidity draws the majority of Florida pests indoors.
- Remove food sources — store pantry items in sealed containers, wipe up crumbs, and keep trash covered.
- Trim back the yard — keep shrubs, tree limbs, and mulch pulled away from the foundation so pests can’t bridge inside.
- Eliminate standing water — a must in our climate, especially for mosquitoes and other biters.
When to call a professional
DIY prevention handles most everyday issues, but call a licensed Florida pest control pro for a true infestation, structural pests like termites or carpenter ants, stinging-insect nests near the home, or anything that keeps returning after you’ve sealed and cleaned. In our climate, termites in particular are worth a professional inspection rather than a wait-and-see approach.
Frequently asked questions
How do I keep pests out year-round in Florida? Seal entry points, control moisture, remove food and water sources, and keep vegetation back from the house. Consistency matters more than any single treatment in our climate.
Can I handle this myself or do I need a pro? Prevention and minor problems are very DIY-friendly. Infestations, structural pests, and stinging-insect nests near the home are safer left to a licensed professional.
Why are pests so persistent in the Panhandle? The warm, humid, subtropical climate lets many species stay active nearly all year, so ongoing prevention beats one-time treatment.
