Pantry bugs are a common problem and can be a nuisance. They are attracted to food odours and will contaminate more food than they eat. While plastic itself doesn't attract bugs, the food stored inside plastic containers can be at risk of infestation. Some bugs are capable of chewing or biting through plastic bags, even freezer-weight ones, to reach their food source. This includes beetles, weevils, and cockroaches. To prevent this, it is recommended to double bag items or use heavy-duty plastic containers.

What You'll Learn
Pantry bugs can chew through plastic bags to reach food
Pantry bugs are a common problem and can be a nuisance. They are not a reflection of anyone's housekeeping skills, but rather a fact of life. These pests can infest stored food products at any point, from production to storage in your home. The good news is that they do not bite or sting people or pets and they do not damage buildings. However, they can indeed chew through plastic bags to reach food.
While plastic itself doesn't attract bugs, the food stored inside plastic containers certainly can. Insects are drawn to food odours and will chew through plastic to reach the source. Pantry pests are most likely to infest products that have been opened, but they can also get into unopened paper, thin cardboard, plastic, foil, or cellophane-wrapped packages. They may chew their way into these packages or crawl through folds and seams. Once they penetrate the outer wrap, they find their food source and proceed to consume it, contaminating more food than they eat.
To prevent pantry bugs from chewing through plastic bags and reaching food, it is recommended to use heavy-duty plastic bags or double bag items for added protection. Additionally, storing food in sealable glass, metal, or heavy plastic containers can help. Inspecting packages before buying and regularly cleaning your pantry and kitchen to eliminate food debris that attracts insects are also important measures to take.
If you already have a pantry bug infestation, removing and discarding infested food, packaging, and thoroughly cleaning the affected area are essential steps in eradication. Vacuuming and washing shelves can help, but be sure to discard the vacuum bag afterward to prevent re-infestation. Freezing items for several days at 0°F can also kill any larvae or adults that may be present.
In summary, pantry bugs can indeed chew through plastic bags to reach food. While it may be inconvenient and unpleasant, there are effective strategies to prevent and eradicate infestations.

Plastic bags can be double-bagged to prevent infestations
Pantry pests are insects that infest stored food products, and they are not a reflection of anyone's housekeeping skills. They do not bite or sting people or pets and they do not damage buildings. However, they contaminate more food than they eat. They can get into food anywhere along the food chain, from the growth stage to storage in a warehouse, store, or home. Pantry bugs can chew through plastic bags and wrapping and hide in the crevices of shelves and walls.
To prevent infestations, it is recommended to double-bag items for added protection. Plastic itself does not attract bugs, but the food stored inside plastic containers can. Insects are drawn to food odours and will chew through plastic to reach the source. Freezer-weight plastic bags can be used for double-bagging. It is also recommended to use tightly closed glass, metal, or heavy plastic containers, or store food in the freezer or refrigerator until you are sure the infestation is gone.
In addition to double-bagging, there are several other measures that can be taken to prevent infestations. Firstly, buy dried foods in small quantities that can be used up quickly, within two to four months. Use the oldest products first and always check the packaging date. Inspect packages before buying and look for evidence of insects, such as holes in the packaging. At home, regularly clean your pantry and kitchen to eliminate food debris that may attract insects.
If you discover an infestation, it is important to remove all infected food and thoroughly clean your pantry, shelves, and cabinets to prevent the bugs from returning. A vacuum cleaner can be used to pick up crawling insects and spilled or infested material. Empty the vacuum cleaner bag after use to prevent re-infestation.

Cockroaches can chew through thin plastic bags and wrappers
Cockroaches are a common pantry pest that can be difficult to eliminate. They are attracted to food and will eat almost anything, including faeces, decaying food scraps, and even plastic bags. Cockroaches have strong jaws with sharp mandibles, allowing them to chew through a variety of materials, including plastic.
While cockroaches can chew through plastic, the type and thickness of the plastic matter. Thinner plastics, such as single-use plastic bags, grocery bags, garbage bags, bread bags, and ziplock bags, are easy for cockroaches to gnaw through. These fragile plastics can tear easily and are no match for a hungry cockroach. On the other hand, thicker plastics, such as the polyethylene blends used for plastic jars, are more resistant to cockroach infestations.
To protect your food from cockroaches, it is recommended to use thicker plastic containers or containers made of glass, ceramic, or metal, which cockroaches cannot chew through. Additionally, ensure that your containers are air-tight and sealed properly, as cockroaches can squeeze through small gaps and are attracted by the smell of food.
It is also important to regularly clean your pantry and dispose of any contaminated food to prevent cockroach infestations. Vacuuming and discarding infested packaging can help eradicate the issue. Inspecting packages before purchasing and storing food in sealable containers can also help prevent infestations.
By taking these precautions and using the appropriate storage containers, you can effectively protect your food from cockroaches and reduce the risk of contamination.

Bed bugs cannot bite through plastic
While some insects can chew through plastic bags, bed bugs cannot. They lack the teeth or mandibles required to bite through even thin plastic. Bed bugs are blood-feeders and pierce the skin with their proboscis to feed.
Pantry pests, such as Indianmeal moths, grain weevils, and flour beetles, are a common problem. They infest stored grain and dried food products, contaminating more food than they eat. They can get into unopened paper, thin cardboard, plastic, foil, or cellophane-wrapped packages. They may chew their way into these packages or crawl through folds and seams.
To prevent pantry pest infestations, it is recommended to buy dried foods in small quantities and use them up within a few months. Inspect packages before buying, checking for holes or tears in the packaging. At home, store food in tightly closed glass, metal, or heavy plastic containers. You can also store food in the refrigerator or freezer, as the cold temperature kills larvae and adults.
If you discover an infestation, throw away contaminated food and thoroughly clean cupboards, shelves, and surfaces where the food was stored. Use a vacuum cleaner to pick up crawling insects and infested material, then discard the vacuum bag. While washing shelves with detergent or disinfectants will not keep pests from returning, sealing cracks and crevices can help prevent future infestations.

Freezing items can kill larvae and adults in infested food
Pantry pests such as Indianmeal moths, grain weevils, and beetles can infest stored food products. These insects do not bite or sting people or pets, but they do contaminate food. They can get into food anywhere along the food chain—during growth, harvest, storage in warehouses, grocery stores, or homes. They may chew their way into packages or crawl in through folds and seams.
Freezing items can effectively kill larvae and adults in infested food. Freezing infested food for at least 3–4 days will kill insects. The ideal temperature to ensure kill rates is minus 44 degrees F (minus 42 degrees C). However, a temperature of 0°F for 3–4 days is also sufficient. After removal from the freezer, objects should be allowed to return to room temperature gradually, preferably still wrapped, to minimize handling until they have adjusted to the new temperature. Freezing is generally considered safe for most object types, and some institutions even freeze collections preventatively to ensure there is no infestation.
To prevent pantry pest infestations, buy dried foods in small quantities and use them up within a short period (2–4 months). Inspect packages before buying and avoid broken or damaged packaging. Check the freshness packaging date. Store insect-free foods in tightly closed glass, metal, or heavy plastic containers. You can also store foods in the refrigerator or freezer.
