Termites eat wood to derive the cellulose and nutrients they need to live. Cornelius is now with the Invasive Insect Biocontrol and Behavior Laboratory in Beltsville, Maryland, and Osbrink is with the Tick and Biting Fly Research Unit in Kerrville, Texas. So Peruvian walnut caused high mortality, but also sustained a high rate of feeding damage; in the rest of the woods, low termite survivability went hand in hand with low consumption rates. They feed on products, which contain cellulose. Termites have protozoa and bacteria in their gut that allow them to break down the cellulose fibers in wood, which is difficult for other creatures to digest. “Our ranking could be a guideline when it comes to a choice of lumber in major termite-ridden areas,” Cornelius adds. When termites were given no choice but to consume just one variety of wood for 6 weeks, six of the woods—redwood, Brazilian jatoba, Peruvian walnut, Honduran mahogany, Alaska yellow cedar, and teak—showed some level of natural resistance and caused an average of better than 75 percent termite mortality. Subterranean termites will happily feed on any of the common woods used for structural lumber in homes.

While this is a good idea, in theory, the fact of the matter is that termites feed specifically on cellulose, means they have the ability to feed on essentially any plant matter. They do not eat wood, bite, or sting, they are simply a nuisance. Termites had significantly lower survival on a diet of teak compared to a group not fed at all—called a starvation control.

Termites actual diet is based upon consuming cellulose. Like most termites, drywood termites eat structural wood from the inside out, leaving a brittle shell. In a number of cases, termite invasions in homes go unnoticed for long periods of time. But today’s growing concerns about the environmental impact of preservative chemicals, such as chromated copper arsenate, used to treat wood against insects got Agricultural Research Service entomologists Mary L. Cornelius and Weste L. Osbrink looking for a better way to build structures with resistance to termites. With the exception of certain termite species that require moisture or soil to survive, the pests only need wood. Should you find termites swarming indoors after the termiticide barrier is applied, do not feel that the treatment was unsuccessful.

The study also provided the first evidence that termites will eat, damage, and survive to some extent on Peruvian walnut. Broadly speaking, termites dislike heartwood. These pests live in colonies under the soil and feed on the cellulose material that is found in plant cells as well as wood. | It’s this movement that causes squeaking, as the hardwood floor boards rub against one another. Termites live on the cellulose found in wood or certain other plant materials, such as cotton. Do termites eat pressure treated wood?

Kim Kaplan, Agricultural Research Service Information Staff. Cedar, however, is considered to be a naturally durable and termite-resistant wood. Habitual impacts of termites are really bad. Therefore, homes are vulnerable to damage caused by termite feeding. A Better Business Bureau Accredited Business. This makes finding food sources easier for the pests. Average termite survival on Peruvian walnut was only 16.4 percent after the 6-week diet, but the amount of Peruvian walnut destroyed was similar to the amount of birch and red oak damaged, both of which are termite-susceptible woods. Subterranean termites … Their disadvantage is that they are extremely harmful to the household. The question was whether or not boards of lumber contain enough of these chemicals to have a real impact against termites.
