Termites are known for their destructive feeding habits, particularly their appetite for wood. However, their dietary preferences extend beyond wood to include other materials such as paper, cardboard, drywall, and even certain types of insulation. Given their propensity to chew through various substances, can subterranean termites also consume plastic bags? While termites have been observed to damage plastics, it is important to distinguish between merely chewing through plastic and actually digesting it. Subterranean termites, such as Formosan termites, have been known to penetrate PVC plastic to reach food sources, but there is limited evidence to suggest that they can fully digest plastic.

| Can subterranean termites eat plastic bags? | No, subterranean termites cannot eat plastic bags but they can chew through thin plastic barriers to reach food sources. |
| Why do termites chew through plastic? | Termites are attracted to food sources that contain cellulose, which is predominantly found in plant matter. Plastic does not offer any nutritional value to termites, so it is unclear why they attack these materials. |
| Which termites can eat through plastic? | Formosan subterranean termites can easily penetrate PVC plastic to reach food sources. Coptotermes acinaciformis termites from Australia have also been found to attack plastics. |

Subterranean termites need moisture to survive
Termites are known to cause fear among homeowners due to their propensity for destroying wooden structures. While wood is their dietary staple, termites can eat a variety of other materials, including cardboard, paper, clothing made from natural fibres, and even carpets, particularly those made from natural materials.
Subterranean termites, in particular, can chew through a range of substances to reach a cellulose food source. They are attracted to materials with high cellulose content, such as paper, cardboard, and drywall. However, they cannot eat plastic and will only chew through thin plastic barriers to access their desired food source.
Subterranean termites require a source of moisture to survive. They dehydrate easily and, therefore, build mud tunnels from their ground nest to protect themselves from dry conditions as they commute into houses. Moisture is so essential to subterranean termites that they will not infest a building unless there is adequate moisture, adequate food, and adequate protection.
Homeowners can take several preventative measures to reduce the risk of termite invasion by addressing moisture issues. These include:
- Inspecting faucets, drain lines, and water lines for leaks and repairing them as needed.
- Installing adequate ventilation in attics and crawl spaces to control humidity.
- Checking cold water lines for condensation and using foam water line insulators if necessary.
- Ensuring that gutters are not leaking and that downspouts are flowing away from the building's foundation.
- Filling in low spots in the yard near the house and sloping the yard away from the building to ensure proper drainage.

They can chew through plastic to reach food
Termites are known for their destructive nature, with a particular appetite for wood. While wood is their staple food, subterranean termites have a more diverse palate. They can and will eat a variety of materials, including paper, cardboard, drywall, particle board, and even clothing made from natural fibres such as cotton or linen. This is because these materials contain cellulose, which is their primary food source.
Subterranean termites also need a source of moisture to survive, which is why they bring mud into the wood they infest. This helps them maintain their moisture requirements as they feed along the grain.
Now, can they chew through plastic bags? The answer is a little more complicated. While termites cannot digest plastic, they have been known to chew through thin plastic barriers to reach a food source. This is because they are opportunistic feeders and will go to great lengths to access cellulose-rich materials. Several reports and studies have shown that termites can cause substantial damage to plastics, especially in Australia, where they are considered the most destructive.
Formosan subterranean termites, in particular, have been known to penetrate PVC plastic and even destroy electrical wires within PVC pipes, resulting in power outages. This is because they secrete formic acid, which can corrode plastic and wiring. Additionally, some species of termites, such as Coptotermes acinaciformis, are more aggressive in attacking plastics.
So, while subterranean termites may not be able to digest plastic bags, they can certainly chew through them to reach food. This behaviour can have serious implications, especially when it comes to underground communication and power cables. Therefore, it is essential to take preventative measures to protect your home and belongings from termite infestations.

They cannot digest plastic
Termites primarily feed on materials high in cellulose, a component predominantly found in plant matter. Their diet is heavily inclined towards plant-based foods. However, termites are also opportunistic feeders and will eat a wide variety of cellulose-rich materials.
Subterranean termites, for instance, can chew through a variety of materials to reach a cellulose food source. They can even chew through thin plastic barriers to reach food. Formosan subterranean termites, for instance, can penetrate PVC plastic to reach food. They have been known to break underground plastic water pipes and destroy electrical wires within PVC pipes.
However, termites cannot digest plastic. They do not gain any nutritional value from it. They simply chew through plastic barriers to reach food sources. Therefore, it is recommended that items made of paper and cardboard be stored in sealed plastic containers to avoid attracting termites.

Formosan subterranean termites can penetrate PVC plastic
Termites are known for their cellulose-eating capabilities, which means they are attracted to paper, cardboard, drywall, particle board, and even clothing made from natural fibres such as cotton or linen. They can also tunnel through carpet fibres, insulation, and certain types of wood to reach a cellulose food source.
While termites do not actively consume plastic, they can chew through thin plastic barriers to reach food sources like wood or paper. This means that while termites cannot digest or target plastic as it contains no cellulose, they may use their serrated jaws to break through thin layers of plastic to reach cellulose-rich materials.
Formosan subterranean termites, for example, are known to traverse thin metal, mortar, PVC pipe, electric power lines, and communications lines to get to wood or cellulosic material. They can gnaw through PVC and other materials as they seek food sources, including wood, synthesized materials, and sometimes softer plastics.
Therefore, while Formosan subterranean termites can penetrate PVC plastic, they do not eat it as a food source. Instead, they chew through it to reach desirable food sources.

They are attracted to cellulose, found in plant matter
Termites cannot eat plastic, but they can chew through thin plastic barriers to reach a food source. Their primary food source is cellulose, which is found predominantly in plant matter. Consequently, their diet is largely plant-based.
Subterranean termites, for example, can chew through a variety of materials to reach a cellulose food source. They can even chew through carpet fibres, particularly if they are made from natural materials. They are also attracted to paper and cardboard because of their high cellulose content.
Certain types of insulation, such as cellulose insulation, can attract termites. They can tunnel through it to create pathways and can also consume it for its cellulose content.
Termites are also attracted to clothing made from natural fibres such as cotton or linen, which contain cellulose. Cotton materials left in damp conditions are particularly vulnerable to termites.
In addition to cellulose, termites require vitamins and nitrogenous foods, such as proteins, which are supplied by fungi normally present in the decayed wood diet common to most termites.
