Protecting New Jersey Homes with Action Termite and Pest Control

Termites are one of the most destructive pests a homeowner can face, and one of the first signs of a potential infestation is a termite swarm. At Action Termite and Pest Control, we specialize in identifying and eliminating termites before they can cause serious damage to your home. Understanding why and when termites swarm can help you act fast and protect your investment.


Why Do Termites Swarm?

A termite swarm is a natural part of the reproductive cycle. When a termite colony reaches maturity, it produces “alates”—winged reproductive termites. These swarmers leave the colony in large groups to mate and establish new colonies.

Swarming is essentially termites’ way of expanding their territory. After pairing off, these alates shed their wings, find a place to nest, and begin the process of building a new colony. While the swarming termites themselves don’t cause damage, their presence is a strong indicator that a mature colony is nearby—often within or near your home.


When Do Termites Swarm in New Jersey?

In New Jersey, the Eastern Subterranean Termite is the most common species. Their swarming season typically begins:

  • Late March through early June

  • Most often after a warm rain, when the ground is moist and the air is humid

  • During the daytime, especially late morning to early afternoon

It’s important to note that swarm timing can vary slightly depending on weather patterns. A warmer-than-usual spring or early rainfall can trigger earlier activity.


Warning Signs of a Termite Swarm

  • Sudden appearance of winged insects indoors or around windows and doors

  • Discarded wings on windowsills, countertops, or floors

  • Mud tubes on foundations or basement walls

  • Hollow-sounding wood or visible damage to baseboards or trim

If you see any of these signs, it’s time to contact Action Termite and Pest Control immediately for a professional inspection.


What Should You Do if You See a Swarm?

Do not panic—but do not ignore it either. A swarm is your early warning system, and swift action can prevent thousands of dollars in structural damage.

  • Collect a sample or take a photo to confirm they are termites and not ants

  • Do not spray over-the-counter pesticides, which can scatter the swarm and mask the issue

  • Call Action Termite and Pest Control for a free termite inspection and evaluation
