What is a Termite Swarm?

Before we delve deeper into the intricacies of termite behavior, let's first establish what a termite swarm is. It's not just a random gathering of flying insects; it's a critical event in the termite life cycle that has significant implications for homeowners.

A termite swarm is essentially a mating flight where the reproductive termites, also known as "swarmers," leave their colony to find a mate and establish new colonies. It's nature's way of expanding the termite population. So, if you see large swarms of termites flying about, be wary because that means these insects are looking for new territory, which could happen to be yours.

A termite swarm is usually a brief event, often lasting less than an hour. However, the aftermath can be long-lasting if these termites find a suitable place to establish a new colony.

Termite swarming season typically occurs during warm, humid weather. But in Florida where warm and humid conditions are the norm, termite swarming season can extend practically year-round, although they are most often observed during the spring and summer months.

Termite Swarm Season in Florida by Species

Now that we know what termite swarms are, let's look at when different termite species swarm in Florida.

Eastern subterranean termite

The Eastern subterranean termite, scientific name Reticulitermes flavipes, is Florida's most common termite invader. Swarming usually occurs from late winter to early spring, often during daytime hours.

These termites are small, brown, and easy to miss, which makes them particularly dangerous. They have a voracious appetite for wood and can cause significant structural damage if not dealt with promptly. Their colonies are usually built underground, and they use mud tubes to reach their above-ground food sources.

Dark southeastern subterranean termite

The Dark southeastern subterranean termite, with scientific name reticulitermes hageni, prefers to make its appearance in the late afternoon or early evening, usually after a warm rain shower. They are darker in color and less common than the Eastern subterranean termite. However, their rarity doesn't make them any less of a threat. These termites can cause considerable damage to wooden structures, often going unnoticed until it's too late.

Formosan subterranean termite

The coptotermes formosanus, or Formosan subterranean termites, are known for their aggressive nature and usually swarm in the late spring. What sets them apart is their large colony sizes, which can house millions of termites.

These termites can cause extensive damage in a short period due to their aggressive nature. They are also known for their architectural prowess, building intricate carton nests that can even infest living trees.

Light southeastern subterranean termite

The light southeastern subterranean termite typically swarms in the early evening or after summer rains. They are lighter in color and less aggressive than other subterranean species. However, their less aggressive nature doesn't mean they are less destructive over time, especially if their presence goes undetected.

Asian subterranean termite

Asian subterranean termites, or coptotermes gestroi, swarm as the sun sets, usually in late spring. They are similar in appearance to Formosan termites but are slightly smaller and less aggressive. However, they still pose a significant threat to wooden structures and prefer Florida's tropical, humid environments.

West Indian drywood termite

The cryptotermes brevis, or West Indian drywood termite, swarms in the fall and is less dependent on moisture, making it capable of infesting furniture and other wooden items. Unlike subterranean termites, these termites live within the wood they consume, adding a unique challenge to their control.

Southeastern drywood termite

Swarming in the late spring, the Southeastern drywood termite, also known as the incisitermes snyderiin scientific circles, is similar to its West Indian counterpart but has its own unique swarming season. These termites are also less dependent on soil moisture and can infest both structural timbers and furniture, making them a unique challenge to deal with.

What Attracts Termites to Homes or Properties?

Knowing what lures these wood-destroying pests to your property is the first step in termite prevention. Let's break down the main attractions.

Food sources

When it comes to food, termites aren't picky eaters. They're primarily attracted to cellulose, a key component found in wood, paper, and cardboard. If your property has stacks of firewood, old tree stumps, or even wooden furniture, you're essentially setting up a termite buffet.

But it's not just the obvious wood sources because termites can also feast on less noticeable items like newspapers, cardboard boxes, and even the paper backing of drywall.


Termites, particularly subterranean termites, are suckers for damp environments. Leaky pipes, poor drainage, and standing water around your home's foundation can create the perfect breeding ground for these pests.

In Florida's humid climate, managing moisture becomes even more critical. Make sure to fix any leaks promptly and consider installing a dehumidifier in particularly damp areas of your home.

Exterior lighting

You might enjoy a well-lit exterior for security or aesthetics, but you're also rolling out the welcome mat for termites. These insects are attracted to light, and exterior lighting can draw them toward your home like moths to a flame. Consider using yellow "bug lights" or sodium vapor lamps, which are less attractive to termites and other flying insects.

Plant debris

Your garden might be your pride and joy, but it could also be a haven for termites. Leaves, wood chips, and other plant debris serve as a food source and nesting ground for these pests. Regularly clear your garden of such debris, especially if it's close to your home's structure.

Preparing the Home for Swarming Season

When it comes to termites, an ounce of prevention is worth a pound of cure. Here are some actionable steps to fortify your home against these wood-destroying invaders.

Window screens

One of the simplest yet most effective ways to keep flying termites at bay is by installing fine-mesh window screens. These screens act as a physical barrier, preventing termites from entering your home during their swarming flights.

Make sure to check the screens regularly for any signs of wear and tear that could let termites sneak through.

Seal cracks and openings

Termites are crafty creatures that can enter your home through the tiniest of openings. Inspect your home's foundation, walls, and windows for any cracks or gaps and seal them promptly. Silicone-based sealants are often recommended for their durability and effectiveness.

Regular inspections

Don't underestimate the power of a thorough home inspection, especially during peak termite season. Pest control companies in Delray Beach and Port St. Lucie provide termite inspections along with control services, providing you with an invaluable opportunity to catch early signs of infestation.

These inspections often include checking for termite droppings, mud tubes, and any visible termite damage, and advice on the next steps to take.

The Sentricon Solution: Your Ultimate Defense Against Termites

After you've done all you can to make your home less inviting to termites, it's time to bring in the big guns. That's where Sentricon comes in. This advanced termite baiting system is a game-changer in termite control. Unlike traditional methods that only target individual termites, Sentricon wipes out the entire colony, from the worker termites to the queen.

How does it work? Sentricon stations are strategically placed around your property, luring termites with a cellulose bait. But this isn't just any snack—it's laced with an active ingredient that disrupts the termite's ability to eat, breed, and even survive. As termites feed on the bait and return to the colony, they share it with others, leading to the collapse of the entire colony.

Choosing Sentricon means you're not just treating a termite problem; you're ending it. And the best part? It's an eco-friendly solution that poses no hazard to your family, pets, or the environment.

So, if you're serious about protecting your Florida home from the menace of swarming termites, Sentricon is the way to go.
