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.

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.
