Learn Termite Warning Signs

Charles Andrews, Regional Extension Agent

If you own a home, it was probably inspected for termites when you purchased it. But just because there weren't termites found then, that doesn't mean you can forget about them. Learn the signs that indicate these pests have moved into the area and you will be able to handle the situation before it becomes a significant problem. When structural damage becomes visible, it's usually the result of years of termite infestation.

There are generally two types of termites which are of concern to homeowners: subterranean and non-subterranean (drywood and powderpost)termites. Non-subterranean termites such as powderpost or drywood termites are generally confined to one structural member of a building or piece of furniture, where as
subterranean termites usually nest in the soil and are the termites homeowners fear most.

Subterranean termites swarming indoors is one sign of infestation and this usually happens in the spring. Winged reproductives, one of the three castes of termites, leave their old colonies and fly in swarms to form new colonies. These winged reproductives will shed both of their pairs of wings shortly after they swarm.

Don't confuse winged termites with winged ants. Ants have narrow, wasp-like waists, while termites have broad waists. An ant's wings are about the same length as its body, but a termite's wings are about twice the length of the body. Bring the insect to the Extension office if you need help identifying it.

Subterranean termite tubes are another sign of infestation. Subterranean termites like dark, moist conditions and will make earth-colored tubes from the ground to the wood they're feeding on. Look for these tubes on basement walls, wooden posts and door and window trim.

Any wood in contact with the ground is especially susceptible. You can make some modifications to your home to help control termites. First, remove all wood debris from around your home. Replace wood posts and steps that contact the soil with pressure-treated lumber or some other non-wood based building material.

Replace any termite-damaged timbers with new pressure-treated timbers. If possible, keep wood 18 inches away from the soil. Make sure basements and crawl spaces are both well drained and well ventilated. Fill any cracks in the foundation with concrete or caulk. The Extension office has two excellent termite publications that can help you identify and manage this pest.

Direct run-off water away from the foundation and make sure that your gutter system is working correctly. This will help reduce soil moisture around your home.

If you suspect that you have a problem or if you find termites, call a reputable pest control professional to inspect your home and property. You may want to get several estimates. Call your local County Extension office for information about termites and other homeowner pests.
