Termite Swarm Season in Virginia Beach: What Every Homeowner Needs to Know

Every spring in Hampton Roads, a natural event occurs that strikes fear into the hearts of homeowners: termite swarm season. As temperatures climb above 70 degrees Fahrenheit and the days lengthen, mature subterranean termite colonies send out thousands of winged “swarmers” to establish new colonies. If you see a swarm near your home, it is a serious warning sign that requires immediate attention.

What Is a Termite Swarm?

A termite swarm is a reproductive event. Winged termites, called alates or swarmers, emerge from an established colony in large numbers, typically after a warm rain in the spring. Their goal is to mate and start new colonies. The swarm itself is brief, usually lasting less than 30 minutes, but the sight of hundreds or thousands of winged insects emerging from the ground or from wood near your home is unmistakable.

When Does Swarm Season Happen in Hampton Roads?

In Virginia Beach, Norfolk, and Chesapeake, subterranean termite swarm season typically runs from late February through May, with peak activity in March and April. The exact timing depends on temperature and rainfall. Swarms most commonly occur in the morning or early afternoon, often on the day after a significant rain event.

How to Tell Termite Swarmers from Flying Ants

This is one of the most common questions we receive. Both termites and ants have winged reproductive forms, and they can look similar at a glance.

Here is how to tell them apart: Termite swarmers have straight, bead-like antennae; a thick, uniform waist with no pinch; and two pairs of wings that are equal in length, both extending well beyond the body. Flying ants have elbowed or bent antennae; a clearly pinched waist; and two pairs of wings where the front pair is noticeably larger than the back pair.

If you are not sure what you are seeing, collect a few specimens in a sealed plastic bag and call us. We will identify them for free.

What to Do If You See a Swarm

First, do not panic. The swarmers themselves are not damaging your home; they are simply looking for a place to start a new colony. However, their presence near your home strongly suggests that there is an established colony nearby, potentially inside your home’s structure.

Second, do not spray the swarmers with insecticide. This will kill the swarmers but will not affect the colony, and it will destroy the evidence that an inspector needs to assess the situation.

Third, call a licensed pest control company immediately. A thorough inspection will determine whether the colony is inside your home, in the soil near your foundation, or in a neighboring structure. Early detection and treatment is far less expensive than repairing termite damage.
