    Subterranean Termites Swarm in Fall Reproduce in Homes

    A termite swarm may be the most evident indicator of a termite infestation for many households. Termites swarm only when the colony has reached a specific size, and the meteorological conditions are favorable for flight. If you notice a swarm of termites surrounding your home, fixed colonies of termites likely live in or near your home.


    Swarms of termites are a regular and required event for termite survival and dissemination. Swarming termites, or alates, will try to enter through small gaps in the walls and base to access free air for the first time when they leave the nest within a home. In addition, because swarming termites are drawn to light, they are frequently seen near windows or light fixtures.

    Subterranean Termite Swarm

    Termites swarm when their initial colony has achieved a critical mass and is ready to expand. This occurs once a year for most colonies. Hundreds, if not thousands, of swarmers known as alates are generated for the sole aim of reproduction and expansion. Swarmers contain both males and females, and the amount of swarmers produced each year varies according to colony size and termite subtype. They reside in the soil closer to the surface of their home until the weather circumstances are favorable for flight. These swarming measures are undertaken at around the same time in all colonies in the vicinity.


    The swarmers take to the air and couple off when the circumstances allow. Once partnered, the couples lose their wings, mate, and look for a new location to establish a nest and populate if one is available. This happens even though there are no neighboring colonies to trade alates. The launches are usually stretched out across a few weeks, with one big one the day before and the lesser ones on the following days.

    Why Does it Happen?

    Subterranean termites frequently swarm in the springtime as well as during daylight hours, whereas dry wood termites wait until late summer or early fall, and termites swarm in the summertime.


    Most genera, regardless of breed, wait until the day after a rainstorm whenever the weather is cloudy, and winds are less than 6 mph. Damp soil promotes the roosting process for newly coupled partners, and higher humidity increases survival rates. On the other hand, Termites do not need to be outside to swarm. They can occasionally overestimate their launching location and swarm inside.


    Look for Infestation

    Because termite swarms signal that a current colony is prospering nearby, investigate your house and property if you observe a swarm near your place. If you suspect termite activity, contact an Orange Country Pest Control professional as soon as possible for a free examination.
