How Seasonal Changes Affect Termites

Termite Infestations Change With The Seasons

When it comes to destroying homes and businesses in the U.S., no other pest can compete with subterranean termites. As we discuss the effect of seasonal changes on termites, we will be focusing on this specific type of termite. Let's take a look.

During the cold winter, when there are a few feet of snow on the ground, termites are less active, or completely inactive, depending on how cold the ground gets and how available food is. But, when they establish a nest under a man-made structure, it may be warm enough for them to continue to be active all winter long and they may feed on that structure even when there is still snow on the ground outside. Temperature is the deciding factor. But, while the cold works against termites in the winter, this season does do something to inspire termites. All of that snow accumulating outside is going to be turned into moisture in the spring, and termites love moisture.


In the spring, most termite nests release swarmers into the air. Swarmers are male and female alates created for the purposes of mating and establishing new nests. They prefer to do this in areas that are moist. If your property has lots of moisture, it will be more interesting to these moisture-seeking pests; while swarmers do not feed on wood, they will look for a food-rich location to create their home. If you have lots of sticks in your yard, or a wood source that has been dampened by the excessive moisture of spring, you'll have the conditions to draw swarmers in.


The ideal temperature for termites is between 75°F and 95°F. This is the condition in summer that will affect termites most. Termites are cold-blooded creatures. That means they are the same temperature as the soil or wood they are crawling around in. If the temperature cools down, termites slow down. It the temperature warms up, termites speed up. No piece of property benefits from "sped up" termites. When termite activity increases, more termites are produced and more damage is done to wooden structures.


In the fall, the temperatures begin to drop, and moisture is not generally an attractant to termites because it is usually too cold. So you wouldn't think that fall would be a time to worry about termites. But, an unnaturally warm fall day can inspire a nest to release termite swarmers early or cause a large nest to split. This split is called budding. When either of these happen, termites can spread from property to property. It is also important to point out that fall is not nearly as cold as winter and, if termites can damage a structure in winter, they can damage it in fall. It all depends on the warmth of soil and wood.

Threat Levels

While summer is the time of year when you can expect termites to do the most damage to your property, it isn't the only time of year these wood-eating organisms can eat away at your equity. That is why termite protection should be year-round.

Termite Control

The experts at Moyer trust Termidor® termiticide/insecticide, America’s #1 termite defense product, to protect homes and businesses in Pennsylvania from termite damage. A liquid barrier treatment creates a complete wall of protection that works to not only eliminate termite workers, but it also eliminates the colony that sent them. When termite workers pass through the barrier, which is undetectable to them, they pick up the termiticide and share it with other termites as they groom each other. Termidor calls this their patented "transfer effect." This transfer effect allows the product to not only take down termites that have touched the termiticide barrier, but any termite that has picked it up from another termite. This works its way back to the colony and takes that colony out. It does this in winter, spring, summer, and fall.

To ensure a constant barrier, and make sure those persistent insects don't find a "hole" in your barrier, we also install GreenEye Alert, which provides an easy visual alert when termites come to feed. You'll never have to wonder if termites are silently, and secretly, consuming your property.
