Pest Control Experts in Lynn.

May is peak termite swarm season for the North Shore and Greater Boston area. These swarms occur when underground colonies release winged reproductives to start new nests, often after a spring rain. Homeowners in coastal towns like Salem, Marblehead, and Beverly should watch for discarded wings on windowsills or mud tubes near foundations. You can distinguish termites from flying ants by their straight waists, beaded antennae, and equal-length wings. Because the North Shore's high water table and historic sill plates increase the risk of structural damage, professional inspection is recommended over DIY sprays to eliminate the colony at its source. Preventing May Termite Swarms in Greater Boston It’s termite season. As soil temperatures rise in coastal towns like Salem and Marblehead, Eastern Subterranean termites begin their annual reproductive cycle. This shift often leads to the sudden appearance of winged insects inside the home, a sight that serves as an early warning for potential structural threats. If you live in a historic New England home, you are likely already aware of the challenges our coastal environment presents. High humidity and aging wooden structures make Greater Boston a primary target for wood-destroying pests. Recognizing the signs of activity this month is the best way to protect your property from long-term damage. Why May is the Month of the Swarm A termite swarm is essentially a colonial expansion. When an underground colony becomes crowded, it produces winged reproductives, often called swarmers. Their only job is to leave the nest, find a mate, and start a new colony. On the North Shore, these swarms are most frequent in May because the soil has finally reached a consistent temperature that signals it is safe to emerge. Usually occurring on a humid afternoon following a spring rain, these swarms can involve hundreds of insects. While the winged termites themselves don't eat wood, their presence inside your home or near your foundation is a clear warning that an active worker colony is nearby, and they have likely been there for some time. Identifying the Intruder: Termite or Flying Ant? In May, we see a significant overlap between termite swarms and the emergence of flying ants. In communities like Swampscott and Lynn, homeowners often struggle to tell them apart. Since the treatment for each is entirely different, identification is the first step. Look for these three physical traits: The Body Shape: Termites have a thick, straight waist. Ants have a very distinct, pinched waist that separates their body segments. The Wing Proportions: A termite has four wings that are all exactly the same length and twice as long as its body. An ant has two large front wings and two smaller hind wings. The Antennae: Termite antennae are straight and look like tiny beads. Ant antennae are elbowed, meaning they have a sharp bend. If you find piles of discarded wings on your windowsills or near door frames this month, pay close attention. Termites shed their wings almost immediately after landing, while ants typically keep theirs longer. The Coastal Risk Factor Our North Shore towns are particularly vulnerable to subterranean termites due to the high water table and the salt-rich soil that retains moisture. In places like Beverly and Peabody, many historic homes feature sill plates—the wooden base of the frame—that sit dangerously close to the soil. Over years of spring landscaping, the addition of new mulch or soil can accidentally create a bridge over your foundation. This allows termites to enter your home undetected. Because they require moisture to survive, they stay hidden within the wood or inside mud tubes, eating away at the structure while leaving the exterior paint or finish looking perfectly normal. Taking Action This Spring Finding a swarm in your kitchen or basement can be overwhelming, but it is a call to action rather than a reason to panic. The most important thing you can do is avoid disturbing the area with household cleaners or bug sprays, which can cause the colony to retreat deeper into the structure, making them harder to track. At Beantown Pest Control, we specialize in the specific architectural needs of Massachusetts homes. Our May inspections focus on identifying active entry points and assessing the moisture levels that attract these pests in the first place. Early intervention this month can save you from the massive headache of structural repairs down the road. If you’ve spotted winged insects or mysterious wings around your home this season, reach out to us for a professional evaluation. We’ll help you determine exactly what you’re dealing with and ensure your home stays protected well beyond the spring.

Spring on the North Shore is a season of transformation. As the ground thaws in towns like Salem and Marblehead, the local landscape comes back to life. Unfortunately, this transition also triggers one of the most stressful events a homeowner can witness: the termite swarm.  If you have lived in a historic New England home for any length of time, you know that our coastal environment—with its high humidity and older wooden structures—is a prime target for Eastern Subterranean termites. As we move into the 2026 season, understanding the difference between a minor nuisance and a structural threat is essential for protecting your investment. What Is a Termite Swarm? A termite swarm occurs when an established underground colony reaches a certain size and sends out "reproductives" to start new colonies. These winged termites, often called swarmers, are frequently the first and only sign a homeowner gets that a massive colony is living beneath their foundation. On the North Shore, these swarms typically happen on warm, humid days following a spring rain. You might find hundreds of discarded wings on your windowsills or see a cloud of insects emerging from a crack in your patio or basement floor. While the swarmers themselves don’t eat wood, their presence means a "worker" colony is nearby, and they are definitely eating. Termite or Flying Ant? How to Tell the Difference In areas like Swampscott and Lynn, we often get panicked calls from residents who aren't sure what they are looking at. Flying ants and termites look remarkably similar to the untrained eye, but there are three clear ways to tell them apart: The Waist: Termites have a thick, straight waist. Ants have a pinched, narrow waist that gives them a "segmented" look. The Wings: A termite has four wings that are all the exact same length. A flying ant has two large front wings and two smaller back wings. The Antennae: Termites have straight, beaded antennae. Ants have elbowed or bent antennae. If you find discarded wings that are all identical in shape and size, you are likely looking at a termite issue. Why Coastal Towns Are at Higher Risk Our North Shore communities are beautiful, but our proximity to the ocean and our abundance of historic architecture create a perfect storm for wood-destroying Raleigh. Salt air and high water tables keep the soil moist, which subterranean termites require to survive. Furthermore, many homes in the Greater Boston area were built with "sill plates" (the wooden beam that sits directly on the foundation) very close to the soil line. Over decades, mulch piles, flower beds, and settling soil can create a direct bridge from the earth to your home’s wooden skeleton. Once termites find that bridge, they can work silently for years before any visible damage appears. Prevention and Modern Solutions Protecting a North Shore home requires a shift in mindset from "reaction" to "prevention." While the sight of a swarm is alarming, the real damage is done by the millions of workers you never see. Modern termite management has moved away from the heavy liquid barriers of the past toward more intelligent, bait-based systems. These systems are strategically placed around the perimeter of your home in towns like Peabody or Danvers. The termites find the bait, share it with the colony, and the entire population is eliminated at the source. This method is especially effective for the rocky, uneven terrain often found along our coastline where liquid treatments may not distribute evenly. Taking Action This Season If you see a swarm, do not spray them with a household aerosol and assume the problem is solved. You have only killed the "messengers," not the colony. At Beantown Pest Control, we provide comprehensive termite inspections that look beyond the surface. We examine the foundation, check for mud tubes, and assess moisture levels in your crawl space or basement. Early detection is the difference between a simple preventative treatment and thousands of dollars in structural repairs. The 2026 swarm season is already underway. If you are concerned about the integrity of your North Shore home, our team is ready to provide a localized, expert assessment to keep your property standing strong for another century.
