How Termites Damage Drywall

Drywall or sheetrock is a material that is used to cover the walls and ceilings of a building. It consists of plaster panels that are covered with a thick sheet of paperboard. Since the drywall contains cellulose, it is a prime target for termites.

Signs that your drywall has a termite infestation

When termites infest drywall, or wood in general, they eat the material from the inside out, so there are very few outward signs that the drywall has termites inside it. A professional will be able to use tools in order to detect termite activity in certain materials, along with some inspection methods that identify telltale signs of an infestation. As a homeowner, it can be hard to tell if you have termite infestation anywhere in the home, so the best option for early detection is to set a yearly termite inspection with a professional pest control company.

Dealing with termites that are infesting drywall

If a termite infestation has been detected in your drywall, the control approach taken will depend on the species responsible. For example, drywood termites require different control methods than subterranean termites.

Drywood termites will build their colonies inside of the cellulose that they feed on. This influences the treatment methods that are available for this species. Small drywood termite infestations are contained inside of a single piece of cellulose, so using localized treatments that destroy the colony where it is can be very effective. However, as drywood termite colonies spread around the home, the true extent of the infestation can be unknown, which means that a different approach needs to be taken. In this situation, fumigation may be necessary. Fumigation is a whole house treatment that requires tenting and the evacuation of the building for a few days.

Subterranean termites on the other hand will not be able to build their colonies inside the drywall. They build their colonies underground, which makes chemical barriers and baiting stations much more effective control methods. Chemical barriers consist of termiticide that is injected in the ground surrounding the home, and baiting stations are small plastic containers filled with a slow acting termiticide that are installed all over the property. Chemical barriers will stop an infestation in its tracks while baiting stations are used to kill off entire colonies.
