If you’re a gardener and you’ve found composting difficult or frustrating, you’re not alone. LAist science reporter Jacob Margolis feels that way too. So, he’s been on a mission to figure out the easiest way to deal with his family’s food waste. The catch: maggots.
Why? Black soldier fly larvae are used around the world to process food waste quickly. And most importantly for gardeners, they leave behind frass: bits and pieces of their exoskeletons and poop. The material has fertilizer profile that's similar to chicken manure.
How? Margolis has set up a home for the larvae in his yard, but there are simpler solutions that involve a bucket and patience.
Read on ... to learn how to start composting with maggots.
Do you hate composting as much as I do?
Even though I know it has benefits for both my garden and the environment, I hate turning the pile and worrying about the right ratio of greens to browns and whether it’s too wet or too dry. And it’s always dispiriting to check for loamy, wonderful compost at the bottom only to pull up chunks of vegetables from two months ago.
And before you ask about worm farms, I’ve tried them too. Let’s just say that at some point, I expect to be held accountable for my crimes against worm-kind.
But for the compost- and time-challenged like me, I think I may have found a solution that allows me to simply toss my kitchen scraps into a bin and have it turned into fertilizer in about a month.
The catch: It involves thousands of maggots.
Don’t bail just yet. I think I can convert you into a larvae lover.
Black soldier flies, a composting powerhouse
Black soldier flies are dark blue and shiny, less than an inch long and don’t buzz around your head or bother you like a house fly might. They also live a handful of days, with their entire existence oriented around laying hundreds of eggs on organic waste so their larvae can go to town and start the cycle of reproduction all over again.
It’s those millimeters-long larvae that are going to speed up the composting process for us.
This is what you'll be dealing with: tiny larvae that turn darker when they're about to become flies.

“Unlike earthworms, [they’re] much more tolerant of a wider range of conditions and food sources. It will eat any organic waste in the larval form,” said Kerry Mauck, associate professor of entomology at UC Riverside.
She and her colleagues recently wrote a paper that describes a food waste processing system driven by black soldier fly larvae that was largely self-sustaining for about two years. Similar systems have been used to process food waste around the world.
The larvae will eat paper, vegetables and fruits, as well as meats and animal fats (two things you're often discouraged from adding to traditional compost), breaking them down into smaller bits that can be further processed by microbes in the soil. Adding organic matter like frass to the soil can help improve soil health.
Importantly, the insect frass that’s left behind — maggot poop, as well as the bits and pieces of exoskeleton they shed as they grow — is an organic fertilizer that has a nutrient profile similar to chicken manure, she said.
The exoskeletons contain chitin — a type of sugar molecule found in the shells of crabs and lobsters that breaks down into tiny pieces over time. When detected by plants, it can prompt them to boost their immune systems in anticipation of insect attacks, making them more resilient, Mauck said.
Composting with the help of black soldier fly larvae may just change your relationship with maggots.

How to build your own black soldier fly system
You’ve got a lot of flexibility, depending on the size of your space and how much food waste you create.
“You don't have to make it complicated at all. It can be set-it-and-forget-it if you want it to be,” said Laura Ingwell, an associate professor of entomology at Purdue University who’s been working with black soldier flies for about a decade.
Her system is quite simple.

She fills a 50-gallon barrel with food waste, lets the soldier flies continuously go through their life cycles over the course of a year and harvests their frass when they die during the winter.
Here in Southern California, we don’t need to worry about extreme cold killing off our larvae, so we can keep our systems rolling year-round.
Simple systems and where to get flies
Your system can be as simple as a bucket or black plastic tote that you toss food waste into. Unlike a traditional compost bin, the containers need only be about a foot deep or so, as the larvae don’t travel far.
Order some black soldier fly larvae from an online store like Symton or Fluker Farms, drop them in and just keep piling more food waste on top over time.
If you don’t want to spend money on black soldier flies, you can also attract your own. Dump citrus and coffee grounds in a bucket, cover it with a screen and place a stack of cardboard pieces on top. Every few days, check the fluting on the cardboard for tiny soldier fly eggs. Once you’ve got a few, drop the cardboard into the food waste and let them eat.
Check inside the cardboard for fly eggs.

My system
My system’s going to be a bit more complicated, as I want to harvest frass repeatedly throughout the year. I’ll have three totes inside a screened-in platform. That should keep the black soldier flies in and other bugs and critters out.
My screened black soldier fly house prevents other bugs from getting in and keeps the black soldier flies from escaping. This should encourage them to keep laying eggs in the containers I'll place inside.

As they close in on three weeks of life, I should see the pupae turn from creamy white to dark gray, and their eating will slow down. At that stage, I’ll start dropping food waste into a new container, so when the first black soldier flies emerge, they’ll mate and lay eggs on the fresh food, keeping the cycle going.
I’ll then be able to drop the first bucket of frass on my veggie garden and fruit trees.
At least, that’s how I’m hoping it’ll work.
Follow along
I'll be documenting my experiment composting with black soldier fly larvae here at LAist and on our social channels. Join me!
Ingwell said they’ll eat pretty much any type of organic waste, including manure, pizza crusts and noodles or even those questionably compostable cardboard takeout containers and light green produce bags. It may take the maggots a bit longer to get through those, Ingwell said. It’s also worth experimenting on your own to see what they consume.
“ I've put a whole pack of hot dogs in there once,” Ingwell said. “ They ate it, and they got really big, but it smelled so bad. My students forbid me from ever putting hot dogs in there again because they hated dealing with the colony when they were on their hot dog diet.”

Larvae from one gram of eggs can eat approximately two pounds of food in a week and a half.
Troubleshooting
Search the internet and you’ll find all sorts of black soldier fly contraptions, like this one, which has ramps for the larvae to march up before they pupate. Ingwell said these systems often don’t work well, and she wouldn’t bother.
If the system is too wet, it may smell rancid and the larvae may try to leave. In that case, throw in some dry wood chips or paper or drain the liquid. When I first started my bin, it took the larvae a bit to get adjusted, and some fled in the process.
If you’re considering using the frass in your garden but you’re disposing of meats, you may be concerned about E. coli. To reduce the presence of microbes in the frass, you can age it for a few weeks, though contamination is an area that needs more research, Mauck said.

Why bother composting at all?
Methane, the second-most-abundant greenhouse gas in our atmosphere, supercharges global warming, as it’s 28 times as potent as carbon dioxide when it comes to trapping heat. In the U.S., our landfills are the third-largest source of methane emissions, according to data from the Environmental Protection Agency. In California, they’re the second-largest source, according to the state Air Resources Board, and food waste is a big part of that.
As organic matter breaks down in oxygen-free environments — the anaerobic, stinky smell swampy waste can generate — the gas gets released. Methane emissions can be mitigated through an aerobic composting process, which is what we’re trying to do when we turn organic matter in a compost pile to make the environment more friendly to oxygen-loving microbes.
It’s one of the reasons why California has taken steps to keep 75% of food waste out of landfills.
So you can throw your green waste into your city's approved bin and have it hauled away every week. But composting effectively in your backyard has environmental benefits: The scraps don’t need to be hauled away and processed.
Of course, the biggest benefit for gardeners is that composting can help feed your plants and improve your soil.

With KNX's shift last month back to AM radio only, we asked Southern Californians to share their memories of listening to the radio.
Why now: Back in April, broadcast company Audacy announced it was moving KNX News — one of the last-remaining all-news FM stations — off 97.1 FM, but keeping the long-running news format on 1070 AM where it's been for more than 100 years. The move officially happened in May to make way for a new sports talk station.
A radio time capsule: AirTalk, LAist's flagship daily news show which airs on 89.3 FM, asked listeners to share their favorite memories of listening to the radio.
Continue reading... for vintage photos from The Los Angeles Public Library's digital archive collections highlighting Southern California's rich radio history.
Southern California was built on radio.
"I can still hear the jingle KFWB News 98,” wrote Taline in Los Feliz, during a recent conversation on LAist's daily news show, AirTalk, which airs on 89.3 FM. “I grew up hearing that in my dad's minivan on the way to and from school. It has a special place in my heart.”
Back in April, broadcast company Audacy announced KNX News — one of the last-remaining all-news FM stations — was leaving the FM dial where it had simulcast on 97.1 FM since 2021. The station, which is also one of the oldest in L.A., is not budging from 1070 AM where it has been on the air for more than 100 years. The move away from FM officially happened in May to make way for a new sports talk station, which Audacy officials called an area of growth for advertisers in today’s media landscape.
The move is one in a long line of changes for radio and a reminder that before podcasts, playlists and algorithms, many Southern Californians built their days around radio broadcasts.

Larry Mantle, now in his 41st year hosting AirTalk, remembers being a kid and dreaming of what it might be like to be behind the mic at one of these radio stations.
“ I grew up with KNX," he said. “My dream job as a kid was to be an anchor on KNX or KFWB, the two local all-news radio stations, 'cause there was nothing like hosting AirTalk that even existed at that point.”
Mantle opened up the phone lines on a recent show to hear from his fellow SoCal radio lovers about the shows they miss and the memories they have. Here's what they had to say:

“When you'd walk down Hollywood Boulevard where the station was, you could hear it playing as you went down the street,” said Olivia in Glendale about KLAC 570 with Al Jarvis.
Larry in Yorba Linda shouted out KBCA Jazz for its 24-hour jazz, saying “When I first moved out here in '68 from Phoenix, which had like an hour a week, it was a real wonder.”
Mark in Glassell Park emailed that he loves KCRW’s Henry Rollins, writing, “I used to bristle at his unique DJ persona, but over time, I came to love him and his crazy eclectic playlists. I find his knowledge in history and punk rock fascinating. He's a gem and a legend."
"I'd like to give a shout-out to all the DJs working at KXLU, the college station at Loyola Marymount University, said Jeremy in Culver City in an email. “That station's been on the air for nearly 60 years. I believe it's one of the best examples of what's possible with radio."
"KFWB and KRLA back in the day when they were rock music stations — Dr. Demento, one of my favorite on-air personalities, also had eclectic music taste," said Carrie in Desert Edge.
“ Dr. Demento was must listening when I was a kid in junior high school at Le Conte Junior High in Hollywood,” Mantle added. “Every Sunday night on KMET, we would make sure we were listening to Dr. Demento and his funny records.”
The question remains…

Listener support is vital to any radio station, and it’s clear KNX has many lifelong fans. AirTalk listeners highlighted their support for household KNX names over the decades like Bill Keene, Melinda Lee, Mike Roy and Jackie Olden.
As KNX makes changes, many are watching closely and thinking about the future of radio.
Listeners like Tommy in La Quinta are left wondering if the radio dial will be the same…
“I’m a hardcore listener, but I don't know about casual listeners [and] if they'll tune to AM,” he said.

After months of hand-wringing, Los Angeles and LA28 have come to a tentative agreement on how Olympics organizers will reimburse the city for its expenses for the 2028 Summer Games.
What's in the deal? The private Olympic organizing committee will pay upfront for the estimated cost of services that are not eligible for federal reimbursement, like trash pick-up and traffic control. Under another proposal, the city would also be able to tap an LA28 contingency fund if it isn't fully repaid by the federal government for policing costs at Olympic venues.
What happens now: The agreement is nearly nine months overdue and still needs approval by Mayor Karen Bass and the city council. The City Council's ad-hoc committee on the 2028 Games will meet Tuesday afternoon to vote on the agreement.

After months of hand-wringing, Los Angeles and LA28 have come to a tentative agreement on how Olympics organizers will reimburse the city for its expenses for the 2028 Summer Games.
According to the deal, the private Olympic organizing committee will pay upfront for the estimated cost of services that are not eligible for federal reimbursement, like trash pick-up and traffic control. Under another proposal, the city would also be able to tap an LA28 contingency fund if it isn't fully repaid by the federal government for policing costs at Olympic venues.
The agreement is nearly nine months overdue and still needs approval by Mayor Karen Bass and the City Council.
The 2028 Olympics are intended to be privately financed, and an existing city agreement with LA28 states that the Olympics organizers, not L.A., will pay for extra costs for public services in support of the Games. But L.A. is the financial back-stop for the Olympics, meaning if LA28 goes in the red, taxpayers will pick up the bill.
Beyond that, the city services agreement presents another area where L.A. could incur additional unexpected expenses for hosting the Games. L.A. City Councilmember Monica Rodriguez warned LA28 CEO Reynold Hoover earlier this year that a bad deal could "bankrupt" the city.
Jacie Prieto Lopez, an LA28 spokesperson, and Paul Krekorian, who leads the city's office of major events, said in statements that the freshly inked agreement would help deliver a fiscally responsible Games.
"Mayor Bass’ priority is that the 2028 Olympic and Paralympic Games be fiscally responsible, protect taxpayers, and benefit Angelenos for decades to come. This agreement helps deliver that commitment," Krekorian said.
But the contract between the two parties doesn't fully resolve one of the biggest areas of financial risk for the city: the enormous cost of security for an event as extensive and high-profile as the summer Olympics and Paralympics.
The federal government has so far allocated $1 billion for security costs for the Olympics. Exactly where those federal funds will go has not yet been determined, and there's no guarantee they will cover all of L.A.'s policing costs.
To address this, city officials have also proposed an amendment to a 2021 agreement between the city and LA28. That amendment would establish that if L.A. is not reimbursed by the federal government for all its eligible expenses, it could dip into LA28's contingency fund of $270 million before the private organizing committee could use those funds for any legacy projects.
But that bucket of money will first be used for any costs that Olympics organizers still owe if they run out of revenue — meaning if the Olympics don't turn a profit, the city's access to that money will depend on how much is left for the taking.
Civil rights attorney Connie Rice, who has been tracking the city's negotiations with LA28, told LAist the agreement was a "PR document" not a deal. She pointed out that if the federal government does not pay up for security spending as expected, L.A. could be in trouble.
" It leaves the taxpayers with a GoFundMe strategy," she said.
The city services agreement lays the groundwork for more negotiations between LA28 and the city. Each venue will require its own agreement, to be negotiated by July 1, 2027. Venues in the city of L.A. include Dodger Stadium, the L.A. Convention Center, L.A. Memorial Coliseum and the Venice Beach Boardwalk.
The City Council's ad-hoc committee on the 2028 Games will meet Tuesday afternoon to vote on the agreement.

Topline:
Los Angeles Mayor Karen Bass signed a pair of executive orders Monday to ramp up efforts to clean the mess left by the fire that burned for a week at a Boyle Heights warehouse.
Why now: Since the warehouse fire was put out, the 85 million pounds of frozen food stored inside is now rotting, spreading foul smells throughout surrounding neighborhoods and raising concerns about an influx of pests. Residents have also been left with worries about air and water contamination after the fire and possible long-term public health effects.
Spoiled food removal: Bass and city officials said Monday the warehouse owner, Lineage, began moving food debris on Sunday to landfills in Ventura and Riverside counties. The company predicts it will take 5,000 truckloads to remove it all.
Reducing odors: Lineage plans to apply a chemical deodorizer, likely chlorine dioxide, to the food, debris and trucks leaving the warehouse. It’s also installing devices within the warehouse that will spray mist over the food inside until it is moved.
Pest control: Lineage is responsible for pest management inside the warehouse, while the city of Los Angeles is responsible for it outside the warehouse. Both have hired private contractors to manage pest control.
Air and water testing: The South Coast Air Quality Management District is overseeing efforts to measure harmful material in the air and posting data to its online air quality map. Lineage also hired private contractor Onterris to monitor air quality in the community surrounding the warehouse, with South Coast AQMD’s oversight. The Los Angeles Department of Sanitation has been monitoring water flowing from the site since firefighting operations began. It’s using a variety of methods, including containment tanks and catch basins, to divert the runoff into the sewer and prevent it from flowing into the L.A. River.
What’s next: Bass’ two executive orders are intended to accelerate cleanup efforts, protect residents and hold accountable the companies responsible for the facility and its safety. One order directs the Fire Department to report on its investigation into the cause of the fire within 90 days. The orders also include a number of provisions to help Boyle Heights residents and businesses, including free public transit, financial assistance and expanded public health resources.
Why it matters: Officials and advocates have called for transparency around the cleanup, especially because they say the neighborhood has been historically under-resourced and disproportionately subjected to environmental burdens. One of the orders signed Monday directs city officials to compile a report within 45 days on industrial areas across Los Angeles that sit close to homes and schools. The report also must include possible zoning and land use changes that would reduce negative health effects from existing and future industrial facilities.

L.A.’s lead homelessness agency, LAHSA, filed a lawsuit against the U.S. Department of Housing and Urban Development on Monday, asking a judge for relief from a federal funding suspension it calls unjustified.
How we got here: On June 11, HUD suspended the Los Angeles Homeless Services Authority from federal grant activity pending an investigation into alleged mismanagement. The federal agency said the suspension means LAHSA cannot fulfill its role as collaborative applicant for the entire region’s application for federal homelessness dollars for the upcoming fiscal year. In its lawsuit, LAHSA says the suspension is the Trump administration’s back door attempt to eliminate the Continuum of Care program in L.A., which gives local officials discretion over homelessness projects submitted for federal funding.
LAHSA’s challenge: LAHSA says HUD has failed to identify any public agreement or transaction that LAHSA has violated or cite proper evidence of mismanagement. LAHSA also claims several inaccuracies and misrepresentations in HUD’s original suspension letter, including relying on reviews that LAHSA says were irrelevant to federal funding. “HUD supports its position with an amalgamation of uncorroborated hearsay information apparently cherry-picked from the internet,” the complaint states.
Legal argument: LAHSA's attorneys contend that HUD unlawfully suspended funding, arguing that the action violates the Administrative Procedure Act, the Constitution's separation of powers principle, and the Tenth Amendment. LAHSA is asking for a stay of the HUD suspension pending judicial review and a permanent injunction barring head from suspending LAHSA or blocking the work of the Los Angeles Continuum of Care.
Why it matters: The deadline for the L.A. region to submit its application to HUD for regional homelessness grants is Aug. 26. LAHSA says the suspension jeopardizes $241 million in federal funding that supports more than 11,000 people across L.A. County. LAHSA says the HUD suspension could prevent the agency from other activities, including releasing the findings of its 2026 homeless count conducted in January.
