Maggots in compost are a common source of concern. They believe their composting went awry, and that pouring it over their garden soil may damage their plants or attract vermin and other animals in the long run.

What is the truth? Maggots in compost indicate a healthy environment. 

These larvae contribute to the success of your compost by speeding up the decomposition process and providing additional nutrients to the mix.

We’ll explain what maggots in your compost indicate, how they may help you, and more in the sections below. So continue reading!

Maggots in Compost: What Are They?

Maggots come in a variety of shapes and sizes, and they might show up in your compost. 

The most common one, though, is known as the European fly soldier (Hermetia ilucens). This fly is endemic to Europe, as its name suggests. Nowadays, you can find it all over the world, from the United States to Latin America and even Asia.

The larvae are dropped in the decaying materials by the fly when it is ready to give birth. Anything from rubbish to diapers might fall into this category. For their grubs, anything that is decaying (soft and easy to eat) is ideal nourishment. 

They sometimes opt to bury their maggots in compost. This is when your bin begins to move and you get concerned (or disgusted). 

What Do Compost Maggots Look Like?

The soldier fly larvae, which are gray-white in color, are the most frequent. The body of this maggot is often segmented. In terms of size, they may grow up to one inch long.

They have a cylindrical form, like other maggots. These fly larvae, on the other hand, are a little flattened, particularly at the head. You could notice small hairs, spines, and even pores on the rest of the body (they use for breathing). The skin seems tough and has a leather-like texture. 

You’ll know they are soldier fly larvae if you see the black half-inch adult flies scurrying about. Their wings have a smokey black color with long legs. When these flies are flying about, they generate a lot of noise (an annoying buzzing).

What Causes Compost Maggots?

What makes you think the larvae ended up in your compost? This may be perplexing, especially if you’ve been composting your wastes for a long time and haven’t seen anything like it before.

But don’t be concerned. It’s perfectly natural.

Composting material is a favorite of flies. Anything that is deteriorating would seem to be the ideal location for the flies to lay their eggs.

Why? Because their larvae are unable to breakdown food on their own. They will struggle unless it is fruit or something simple to digest.

However, this is not the case with decaying food. It is easy for them to eat, giving it an excellent environment for them to develop and eventually become flies. 

Furthermore, the decaying material in compost is almost ideal for them. They become the optimal habitat if you only keep organic plants like clippings, vegetable cuttings, and leftovers from grains or fruits. 

This occurs often when there is no humidity present. Compost bins become the most humid site, so flies quickly discover that it is the only place where they can lay their larvae. Organic compounds are simpler to break down because of their high water content.

In a nutshell, compost provides an ideal environment for maggots to consume and thrive. That’s why flies like to deposit them in your trash can or tumbler. 

Are Maggots in Compost Beneficial or Harmful?

Maggots in your compost are a common occurrence, as you are aware. Is this a good thing or a negative thing?

To be honest, it mostly depends. Maggots in compost, on the other hand, are typically a favorable indication. 

Why would they be beneficial? There are several explanations for this. Maggots, for example, decompose organic matter. They leave traces of processed food behind when they consume it, which helps it breakdown quicker. 

Another argument is that maggots do not harm plants or animals in any way. Despite the fact that flies are often associated with illnesses, their larvae are not always disease carriers. They’re probably harmless, especially if they’re growing in very nutritious organic stuff.

Maggots may also help you improve the quantity of compost you make. Yes, if you kill maggots inside before they turn into flies, they may generate fantastic organic material. 

Most of the time, it’s a win-win scenario.

Is there a disadvantage to allowing maggots to thrive in your compost?

There are a couple of them. They are, however, insignificant.

Maggots in the compost, for example, indicate more flies. It may be aggravating when this occurs, particularly in a kitchen or other confined space. Flies aren’t the most enjoyable insects to have around.

Aside from that, larvae consume organic matter. If you’re not cautious, a swarm of maggots might completely deplete your compost container. Fortunately, if you catch maggots early enough, this is unlikely to happen. In fact, unless you leave the compost alone for many months, it’s almost difficult. 

What Should You Do If You Find Maggots in Your Compost?

So, what are your options? Is it safe to let those maggots alone?

Yes, of course.

It’s a good idea to let the larvae alone for a few days or weeks before releasing them into the wild. If you live in a cold climate, it might take anything from 1 to 8 weeks for the larvae to hatch and become flies. They may hatch in as little as three days in warm regions.

So be cautious. Later on, you don’t want to be overrun by flies. This might also imply more maggots, which will eat away at your compost (which you don’t want).

There’s nothing to be concerned about. Give the maggots some time to aid the decomposition process along, then kill them. 

How Do I Keep Maggots Out of My Compost Bin?

Assume you hate maggots. They disgust you and make you vomit at times. You don’t want any of these in your compost pile. 

In that scenario, how can you prevent them? Here are a few pointers to keep in mind:

Set up a Screen

Installing a screen on open compost bins and tumblers will be quite beneficial. Something with tiny enough holes that flies won’t be able to get through.

However, you are not need to install a permanent screen. Adapt it so that it may be removed anytime you need to add additional residues or remove the compost. A piece of cloth or plastic might also be used. 

Close the bin/tumbler while not in use.

Isn’t it self-evident? You’d be amazed how many folks are unaware of this. Allowing flies inside the compost bin or tumbler is a sure-fire technique to attract them. And when that occurs, the obvious result is a maggot-infested party inside. You may avoid this by keeping everything closed. 

Increase the amount of dry material

Flies love decomposing material that’s also humid. To keep them from even trying to fly around, you can always Increase the amount of dry material into the bin or tumbler. This includes dry clippings, leaves, and general residues. Any organic that’s brown and dry will make for an excellent addition. 

Dispose of the Scraps 

Assume you added some dry stuff, but it was insufficient. In that scenario, you’d be better off purchasing the remaining scraps, which are organic. Keep the humidity low by covering them completely with dry material. This will lessen the odor that escapes and deter flies from attempting to enter.

Pour a Lime Juice 

Finally, lime juice may be poured over the remnants to keep flies from leaving the maggots behind. Lime not only decomposes with the rest of the elements, but it also repulses the insects. The lime’s acidity acts as a natural insecticide.

Overly much lime might raise the pH of the compost, making it too alkaline. This might have an impact on how effectively it functions. Pour just 1 cup of lime juice per gallon of compost to avoid this. 

How Can I Get Rid of Maggots in My Compost Bin?

What if you want the larvae but don’t need all of them? In such situation, how can you get rid of maggots in compost?

Once again, there are several options. The following are the most common:

Remove them by hand

This might be a fantastic option for anyone bold enough to stick their hand into the compost and pick out the maggots one by one.

You may either thrash them out of the compost, feed them to farm animals, or just kill and bury them. In any case, you’d be minimizing the number of living maggots in the trash or tumbler.

Every several days, kill the maggots.

You can always destroy the maggots if you aren’t frightened of it. This is a simple task. It’s as easy as using a mortar or scraper to compress the compost. After a few minutes, you should be able to destroy some of the larvae within. It’s not the most hygienic or convenient method, but it gets the job done without spilling anything.

Allow other animals to consume them.

If you don’t want to come into touch with the compost or the worms, keep in mind that many animals like eating them. Wild birds and hens are included in this category. Maggots may be appealing to certain dogs and cats. Finally, they may be eaten by mice and rats. What is the advantage? Maggots are high in protein.
