Subterranean Termites in the Florida Keys
Why Subterranean Termites Are a Serious Threat
Subterranean termites are among the most destructive pests in the Florida Keys, causing millions of dollars in structural damage each year. Living in the soil, they build hidden mud tubes to reach wood structures and often remain undetected until significant damage has occurred. Our warm, humid climate allows them to stay active year-round, making professional inspections and treatment one of the best ways to protect your home.
Signs of Subterranean Termites in the Florida Keys
• Mud tubes along foundations, walls or piers
• Hollow-sounding wood
• Swarming termites, especially after rain
• Discarded wings near windows or doors
• Bubbling or blistered paint
• Visible wood damage

Subterranean Termite Treatment
Subterranean Soil Treatment
Our treatment begins with a thorough inspection to locate active termite activity, including mud tubes, damaged wood, and other signs of infestation. We treat active areas and create a protective barrier around your home by applying professional termite products to the soil surrounding the foundation.
When necessary, we drill through concrete slabs, patios, walkways, or other inaccessible areas to ensure the treatment reaches the soil where subterranean termites live and travel. By treating termites at both the source and along their travel routes, we help eliminate active infestations while protecting your home from future termite activity.
Subterranean Termite Bait Stations
Termite bait stations are installed around the perimeter of your home to monitor for termite activity and help eliminate entire colonies. The stations contain a monitoring material that termites naturally feed on. When activity is detected, the monitoring material is replaced with a specialized bait that worker termites carry back to the colony, helping eliminate it over time.
Our technicians inspect each bait station quarterly, replacing bait and monitoring for new termite activity to provide continuous protection year-round.

Frequently Asked Questions
-
Common signs include mud tubes on walls or foundations, swarming, termites, discarded wings near windows, or doors, hollow, sounding wood, bubbling paint, or wood that appears soft or damaged. Because termites often remain hidden for months or even years, many infestations aren't discovered until significant damage has occurred.
-
Subterranean termites, live underground and travel through mud tubes to reach wood. They require contact with soil or moisture to survive. Dry wood termites, live entirely inside dry wood, and do not need contact with the soil. Because they behave differently, each species requires a different treatment approach
-
Yes. Subterranean termites are one of the most destructive structural pest in the Florida Keys. Our warm, human climate allows them to remain active year-round, and older homes, elevated homes, and buildings with wood to soil contacts are especially vulnerable.
-
Yes. Although termites cannot eat concrete, they can travel through cracks and slabs, expansion joints, plumbing, penetrations, and other openings to reach wood framing inside a home.
-
Treatment options typically include a professional soil treatment, a termite bait station system, or a combination of both. After inspecting your property, we recommend the treatment that best fits your homes, construction and level of termite activity.
-
Neither method is automatically better – they serve different purposes. Soil treatments provide an immediate protective barrier around the structure, while bait stations monitor for activity and help eliminate termite colonies over time. In some situations, using both methods provides the best long-term protection.
-
Williams Pest Control inspect termite bait stations every quarter. During each visit, we check for termite activity and replace monitoring cartridges or bait as needed,.
-
In most cases, no. Most sub training, termite treatments can be completed without requiring homeowners to leave the property. Your technician will explain any special instructions before treatment begins.
-
Store-bought products rarely eliminate an established subterranean termite colony. Because termites often enter through hidden areas beneath the home, professional treatment is usually needed to reach the colony and protect the structure effectively.
-
Williams Pest Control provide sub training, termite inspections and treatments throughout the Florida Keys, from Key Largo to Key West.
-
No. Tenting (fumigation) is designed to eliminate dry wood termites – not subterranean termites. Because subterranean termites live in the soil beneath your home, they are generally unaffected by fumigation and can continue entering the structure after the tent is removed. Proper treatment typically involve soil treatments, termite bait stations, or a combination of both.
