Termite Season in Burlington County: Protect Your South Jersey Home

Termite Season Is Coming to Burlington County

Every spring in Burlington County, as soil temperatures rise above 50°F, Eastern Subterranean Termites begin their annual swarm. Winged reproductives — called alates — emerge from established colonies to launch new ones, and for Burlington County homeowners, seeing swarmers near a window or foundation is one of the most important pest warning signs of the year.

Swarm season in Burlington County runs from late March through May, with peak activity in April on warm, humid days after rain. If you've seen them inside your home, near your foundation, or emerging from the soil around your structure, an active colony is already present — and the damage clock has been running.

Why Burlington County Has High Termite Pressure

Eastern Subterranean Termites (Reticulitermes flavipes) thrive in the sandy, moisture-retaining soils found throughout Burlington County, especially in communities adjacent to the Pine Barrens. The foraging range of an established colony can extend 20+ feet underground, allowing workers to reach your foundation from surprising distances.

Several Burlington County communities face especially elevated termite risk:

• Burlington City and Mount Holly: Historic wood-frame homes dating to the 1700s and 1800s, many with crawl spaces and older wood framing that has never been treated, represent the highest-risk profile in the county. These homes were built before pre-construction termite treatment was standard practice, and many have had only sporadic or no professional treatment in their lifetime.
• Moorestown: The mature oak and maple canopy provides abundant natural wood food sources adjacent to residential foundations. Older homes near the historic district frequently have untreated crawl spaces with wood-to-soil contact.
• Marlton and Mount Laurel: Homes built in the 1990s and early 2000s often received pre-construction termite treatment — but that treatment has a lifespan of 10–15 years. Many of these homes are now in a window of expired protection that termites are ready to exploit.

Understanding the Annual Damage Equation

The average termite infestation in New Jersey causes $3,000 in structural damage before the homeowner notices a single sign. Colonies work silently inside walls, under flooring, and through crawl space framing. By the time floors sag, doors stick, or mud tubes appear on visible foundation walls, the colony has typically been active for 2–5 years.

The math is important: liquid termiticide treatment for a typical Burlington County home costs $800–$1,500. Structural repairs after significant termite damage cost $3,000–$15,000 or more. Annual termite inspections cost $150. The financial case for proactive treatment and inspection is overwhelming.

Treatment Options for Burlington County Homes

Liquid termiticide barrier ($800–$1,500): The most common treatment for Burlington County homes. Applied around the perimeter of the foundation and under slabs, it creates a continuous chemical zone that foraging workers contact and carry back to the colony. Results are rapid and long-lasting — most professional-grade products provide 5–10 years of protection.

Termite bait station systems ($1,200–$2,500 + annual monitoring): In-ground stations placed around the home attract foraging workers, who consume and distribute a slow-acting bait throughout the colony. Effective at eliminating entire colonies rather than just blocking foraging. Recommended for properties where soil treatment access is limited (concrete slabs, tight foundation conditions).

Combined liquid + bait approach: For active infestations in older homes, combining both provides immediate barrier protection plus colony elimination. Particularly recommended for Burlington City and Mount Holly's older structures where infestation risk is highest.

Signs Termites Are Already in Your Burlington County Home

• Mud tubes on foundation walls, crawl space piers, or along joists — pencil-width tunnels of soil that termites build to travel between ground and wood
• Discarded wings on windowsills after swarm season — equal-length, translucent wings shed immediately after landing
• Hollow-sounding wood when tapping baseboards, door frames, or sill plates
• Sagging floors or soft spots in areas above crawl spaces
• Buckling or blistering paint on wood surfaces with no moisture source
