Choosing Small, Medium or Large BSFL

  • Small: approximately 0.25 inches (6 mm), for hatchlings and very small pets.
  • Medium: approximately 0.5 inches (13 mm), for young and small-sized reptiles.
  • Large: approximately 0.75 inches (19 mm), for most adult reptiles.

Choose by your pet's size and feeding ability. As a general guide, choose larvae no larger than the space between your pet's eyes.

Storing live black soldier fly larvae

Keep your live BSFL in the cups they come in, with the lids on, at room temperature for use within about two weeks. For longer storage, keep them at around 55°F (13°C) for up to four weeks. This is warmer than a typical household refrigerator.

See our Live Feeder Care Guide for the full instructions.

Great BSF

I’ve been buying BSF for my chameleon’s and geckos for years. Symton BSF are always plump and lively, and the best prices. I’ll let them grow out into flies and my reptiles love to hunt them. Their customer service is also great. I live in Vegas and always do hold for pickup. My post office accidentally left them on my porch and they all cooked. Symton was awesome in replacing me everything immediately.
I will put bananas, squash, apple pieces or any old scraps of veggies/fruits and these guys devour them.

Amazing!

Great packaging, all were alive and incredibly active.
No mites, no gnats, no pests, just BSF Larvae.
Very good genetics/quality and zero complaints/suggestions.
They were small when I got them, but they are growing fast (I consider them both pets and feeders. I love watching them eat and grow).

My picture and picture isn't great, but I wanted to share some pictures anyway, to make the review section a little more fun.
The portrait picture is the day I got them and put in some food. The landscape picture is 5 days later with other food.

Great first experience!

I am a new beardie owner and researched many sites before I decided where to order bugs for Zulu. I am so glad I did because when I was quarantined with a new baby beardie I had to order quickly. Customer service was great, my order arrived quickly, all alive and very healthy, and better price points than others. Zulu has enjoyed the bsfl and is ready to try some dubias so I already placed my second order! Thank you!

So impressed!

First time ordering and it got lost in the mail but Symton shipped out a replacement right away! Top notch customer service and for once I don’t feel like I’m being ripped off buying feeders. Huge fan of the quality and quantity as well. Keep up the great work Symton!

My beardie wont eat them

I thought the shipment was all dead but give it about 2 days and they revive. You def get a lot but for me it was unnecessary to have that many since she won’t eat them except in salads chopped up

We love symton! We are definitely a customer for life! All of my Bearded Dragons love them and my chicken breast loves to chase them once they have turned into flies! Thank you guys for everything!!

Beardie loves it

Finally! I've tried crickets and dubias as his meal staple, yet he never ate enough in a day. He loves BSFL and I've finally started seeing him get bigger. Will order again.

High quality feeders!

I am very happy with my purchase for my baby bearded dragon. The bugs are super lively, healthy, and attractive to the dragon. The substrate is very very easy to separate with a strainer. Customer service was extremely responsive with all the questions I had. I am a customer for the life of my dragon!

Amazing as Always!

I always have troubles ordering insects during the winter. I don't even bother trying to order crickets at this point. But I have 4 adult chameleons and 7 babies to feed. I ordered large for my breeders and smalls for the babies and they love them! They also love the flies when they hatch out. They are the easiest feeders to keep happy and they last a long time unlike many others.

1st order for my new Bearded Dragon

My Spyro loved them! I'd had him over a week and he had no interest in greens, he'd eat some crickets but didn't like them dusted in calcium. I read great reviews about Symton BSFL. Ive already upped my order and put it on autoship! Super fast shipping also.

Small BSFL

I purchased the small BSFL for my 1 month old ambilobe panther chameleon. They arrived within two days and they were exactly the size described. My baby chameleon immediately noticed them and has been eating them daily. They are now a staple feeder for all of my chameleons.

Small Black soldier fly larvae

I got these for an anole lizard who had hitchhiked in someone's plant from Florida to Ohio. Since they aren't native here the person didn't want to throw it outside so I took it in. I got these to see if I could get the little guy to eat them. He wouldn't. But that could be because he's stuck in captivity- so I can't hold that against Sympton. I have a bearded dragon who will absolutely devour them, so i have been trying to feed them to keep them alive so I can pass them on to the dragon when I am sure the anole won't try them.

My mistake

Unfortunately most of the bsfl in my shipment were dead. I forgot to purchase a heat pack with my order and didn't realize my mistake until after it had shipped. By the following morning the few bsfl that had survived through shipping were all dead.
I also should have requested medium bsfl instead of small ones. They were much smaller than I thought they would be.
I'm a bit of a scatterbrain due to mild Parkinsons, so it was my goof up.
Anyway, I'll order another shipment when I'm not flat broke.

They are all good and alive

The BSFL are all good, alive. But unfortunately my bearded dragon refused to eat them. My beardie only eats dubias.
