Insects that can eat through plastic bags
Plastic waste is a major environmental concern, and while insects may not be a complete solution, they could be part of the answer.
The Galleria Mellonella, or greater wax moth caterpillar, has been found to be able to munch through plastic bags. In a 2017 study, these larvae were left with a commercial shopping bag and were observed breaking it down faster than the well-known plastic-eating bacteria Ideonella sakaiensis. The wax worm larvae were able to break down the plastic into smaller molecules, and they did this at room temperature. It is important to note that the wax worms were not eating and deriving energy from the plastic, but rather, enzymes in their saliva can oxidize plastic polymers.
Other plastic-eating insects include the Indian mealmoth, superworms, yellow mealworms, and crickets. These insects have been found to eat different types of plastics, including polyurethane, polyethylene, polystyrene, and polyvinyl chloride. However, the amount of plastic they can consume is small, and it is not yet known if the insects fully digest the plastic or if it remains as microplastics within their bodies.
While insects may not be the sole solution to plastic waste, they could be part of a larger strategy. Insect-assisted biodegradation of plastics is environmentally sustainable and cost-effective, as it does not require any special conditions. Additionally, the larvae's excrement (Frass) does not contain any plastic or harmful materials, so it can be used as organic compost. Furthermore, the larvae themselves are a good source of protein and can be used as animal feed.
It is worth noting that some sources suggest that insects may not be able to chew through thicker plastic bags, and the thickness of the bag may be a determining factor.

Insects that cannot eat through plastic bags
Plastic waste is an ever-increasing burden on the environment, and insects have been found to be able to biodegrade plastics in a environmentally sustainable and cost-effective way. Mealworm larvae (lat. Tenebrio molitor), for example, can degrade several types of plastic such as Styrofoam, polyethylene, polyvinyl chloride, and polyurethane. However, not all insects can eat through plastic bags.
Bed bugs, for instance, cannot eat through plastic bags, although they can fit through holes the size of a pinprick. Plastic bags are often used as a method to contain and control bed bug infestations. By sealing infested items in plastic bags, the bugs are isolated and will eventually starve, as they can survive without drinking blood for only two to three months. However, it is important to note that this method may not be effective if the bags are not properly sealed, as bed bugs can still find their way out and spread the infestation to other locations.
Another way to use plastic bags to combat bed bugs is in conjunction with heat treatment. Some sources suggest placing well-sealed plastic bags containing infested items in a hot car, as temperatures above 119 degrees Fahrenheit are required to kill bed bugs. However, this method may not be practical or accessible for everyone.
While insects like mealworm larvae are being explored for their ability to biodegrade plastics, it is important to note that not all insects possess this capability. Bed bugs, in particular, cannot eat through plastic bags, making plastic an effective barrier and tool in managing infestations when used correctly.

Thickness of plastic and ease of chewing
The thickness of plastic plays a crucial role in determining its resistance to chewing and other forms of physical stress. Thicker plastics generally offer greater durability and are more challenging to chew through compared to thinner variants.
In the context of plastic bags, their thickness can vary depending on the intended use and manufacturing processes. Common plastic bags, such as those used for grocery shopping or trash disposal, typically fall within a specific thickness range. This thickness is designed to balance durability and ease of use while minimizing production costs.
While the specific thickness of these plastic bags may differ, they generally fall within the range of 0.04 mm to 0.15 mm. This thickness is relatively thin compared to other plastic products like water bottles or storage containers. As a result, plastic bags may be more susceptible to tearing or puncturing, including from chewing by insects or animals.
Wasps, for example, are known to be able to chew through thin plastics. According to wasp control sources, wasps have the ability to damage phone lines and penetrate thin plastic materials. This suggests that insects with strong mandibles or chewing capabilities can potentially chew through plastic bags, especially if the plastic thickness is on the lower end of the typical range.
Additionally, it is worth noting that the ease of chewing through plastic can also depend on other factors beyond thickness. The type of plastic, the presence of additives or fillers, and the temperature can all influence how easily a plastic material can be chewed or punctured. In the case of chewing gum, for instance, studies have shown that chewing releases microplastics into the saliva, indicating that the plastic is being broken down to some extent during the chewing process. However, the overall ease of chewing gum is influenced by its specific formulation, which includes plasticizers and other additives to create the desired texture and elasticity.

Plastic types insects can eat through
It is not clear whether insects can eat through plastic bags. However, there are some insects that can chew through thin plastics. For example, wasps can chew through thin plastics and even plasterboard.
In 2017, molecular biologist Federica Bertocchini discovered that another insect, the waxworm, can eat through plastic. Waxworms are the larval form of wax moths. They are usually considered pests by beekeepers as they feed on the wax that bees use to make their honeycomb. However, when placed in a plastic bag, Bertocchini observed that the worms started producing small holes in the plastic, which began degrading as soon as it touched the worms' mouths. This is because the waxworms' saliva contains two enzymes, Ceres and Demeter, which can break down polyethylene in plastic.
Another invertebrate that can eat plastic is the "superworm" Zophobas morio, which can gain weight from a diet of polystyrene. Mealworm larvae can also digest Styrofoam and are being bred in small areas with readily accessible food to encourage their growth and biodegrade as much plastic as possible. The Tenebrio molitor larvae, which are rich in protein and fats, are also being used to consume plastics with other food and completely process them with the aid of microorganisms in their digestive tracts.

Safe storage from insects
It is important to note that insects can chew through a variety of materials, including thin plastics. Wasps, for example, can chew through plasterboard and thin plastics. Therefore, it is crucial to take precautions to ensure safe storage from insects. Here are some detailed and instructive tips to protect your belongings from insects:
Firstly, it is recommended to use plastic bins with tight-sealing lids as they provide the best protection against insects. Plastic bins are ideal for storing items that are particularly vulnerable to insect damage, such as delicate papers, books, blankets, clothing, and pillows. Plastic bags and cardboard boxes are more susceptible to insect infestations, so it is advisable to avoid relying solely on them for storage.
Secondly, if you are storing perishable food items, it is important to monitor and cycle them regularly. Even a small amount of food can attract insects and put other nearby storage containers at risk. Rice, beans, and sugar can be stored for extended periods, but it is crucial to prevent infestations by insects like weevils and ants.
Thirdly, cloth materials, such as mattresses, couches, pillows, and clothing, are susceptible to moth infestations. To protect these items, consider wrapping them tightly in plastic bags or plastic wrap before placing them in storage containers. Additionally, ensure that the storage area is humidity-controlled, as high humidity can attract moths and other insects.
Another tip is to store the least damageable containers on the bottom. Keep plastic bins on the bottom row, followed by cardboard boxes, and then bags. This arrangement helps protect items that are more challenging to store, such as frames, lamps, and tools, from insect damage.
Finally, it is advisable to inspect your storage area occasionally. Regular checks can help identify any potential insect infestations and allow you to take prompt action. Additionally, consider natural pest control methods by allowing spiders and centipedes to remain in the storage area, as they can help control other pests.
