Can Maggots Munch through Plastic Garbage Bags?

As humans become more concerned about the environment, we are continuously looking for ways to reduce pollution, protect our planet, and find ways to live greener lives. One significant environmental issue is the disposal of plastic waste, which affects our ocean wildlife and ecosystems negatively. In recent times, people have asked whether maggots can eat through plastic garbage bags in the quest to reduce plastic pollution. This article delves into this topic to provide you with accurate information.

What are Maggots and Plastic Garbage Bags?

Before discussing whether maggots can eat through plastic garbage bags, let’s define what each term means.


Maggots are the larvae of flies, and they’re essential decomposers in the ecosystem. They feed on infected or decomposing material, mainly animal remains, and are useful in medicine for their ability to remove dead tissue without harming healthy tissue. Many people use maggots in the process of wound care, especially diabetic ulcers and bed sores.

Plastic Garbage Bags

A plastic garbage bag is a plastic-made bag used for the disposal of waste, usually household waste in a bin or bin liner. They’re made of various types of plastic, such as low-density polyethylene (LDPE) and high-density polyethylene (HDPE).

Can Maggots Eat through Plastic Garbage Bags?

The simple answer is no, maggots can’t eat through plastic garbage bags because they don’t have teeth. The maggots’ digestive system and mouthpart anatomy are not designed to penetrate plastics. However, some factors might make it seem like the maggots ate through the plastic material. Maggots consume organic materials, and depending on the garbage you dispose of, they might be attracted to it and begin to break it down.

Why Are Maggots Attracted to Garbage?

Maggots are attracted to decomposing meat or plant material, and thus they’re drawn to garbage. The reason is simple; garbage contains organic waste material, and it’s the ideal breeding ground for the maggots. As the organic matter decomposes, it creates an odor that attracts adult flies to lay their eggs in the garbage.

What Is the Life Cycle of Maggots?

Understanding the life cycle of maggots helps us appreciate their role as decomposers. Maggots undergo complete metamorphosis, involving four developmental stages: egg, larva, pupa, and adult. Once the adult flies lay their eggs on organic material like garbage, the eggs hatch into maggots within 24-48 hours. Maggots feed for three to five days and then move to a dry location, where they pupate. During the pupal stage, the maggot morphs into an adult fly after about ten days.

How Do Maggots Break Down Garbage?

Maggots break down garbage in two ways. Firstly, they mechanically break down larger items by crawling and tunneling through the material. Secondly, they secrete digestive enzymes that break down compounds in the garbage into smaller pieces, which they can ingest easily. After the maggots have broken down the material, bacteria take over, further decomposing the waste, and producing food for the maggots.

Can Maggots Make Garbage Bags Smaller?

No, maggots can’t shrink the size of plastic garbage bags. As already mentioned, they consume organic material only, and once they have eaten all that they can, the remaining material, such as plastics, remains unchanged. It’s easy to mistake smaller garbage bags to be the result of maggots, but it’s due to the compression of the garbage, either by you or the garbage truck during disposal.

How Can You Keep Maggots From Garbage Bags?

To keep away maggots from your garbage, you need to discourage adult flies from laying their eggs on it. Here are some tips:

  • Never leave your garbage outside overnight. Flies are most active at night, and they will deposit their eggs on your garbage bag if they can.
  • Tie your garbage tightly, so flies don’t have access to it.
  • Keep your garbage in a sealed can instead of a bag. This prevents flies from depositing their eggs on it.
  • Use a garbage can with a tight-fitting lid to keep out flies and other pests.
  • Dispose of your garbage frequently, preferably every one to two days.

What Happens to Plastic Garbage Bags in Landfills?

Landfills are the most common methods of garbage disposal. As such, when we dispose of plastic garbage bags in landfills, they have the potential to cause environmental problems. One problem is the slow rate at which plastics break down, which means that they accumulate in the environment over time. Over hundreds of years, the plastic decomposes into tiny microplastics, which can enter water systems, harming aquatic life and organisms. Additionally, animals can swallow or get entangled up in plastic, leading to harm and even death.

What Are the Alternatives to Plastic Garbage Bags?

The good news is that there are eco-friendly alternatives to plastic garbage bags, including:

  • Biodegradable plastic bags: These bags are made of plant-based materials that decompose easily in the environment.
  • Paper bags: Paper bags are a compostable and recyclable option to plastic.
  • Reusable bags: Reusable bags made of materials like canvas and jute are durable and environmentally friendly.
  • The zero-waste approach: This involves reducing the amount of waste you generate at your home or business. It means using fewer disposable items like plastic water bottles and opting for reusable options.


The bottom line is that maggots can’t eat through plastic garbage bags, which means that you can trust them to keep your garbage bag free of holes. However, having maggots in your garbage bag is never a good sign since it indicates that the garbage bag contains organic waste material that can attract pests and generate an unpleasant odor.
