Black solider fly pupae

Black soldier fly pupae were robust and alive upon arrival. I tried to use them to start a black solider fly farm and unfortunate failed. They died night number 1. Probably something I messed

10,000 bsfl prepupae.

What can I say other than the team over at Symtonbsf.com has been a fantastic supplier of staple feeders for us and this is just another one of their products that does not disappoint.

Always the best

I recently switched to pre-pupae because my pets also like eating the adult flies and I’m very happy I did. Flies within a week of arriving to my house. The chameleons and geckos go crazy for them.

Good product.

These pre-pupae arrived in good condition, many were already morphed to pupae which I expected; good high protein content for my 6 month old beardie. Honest feedback: I was rather unimpressed by the substrate; it was a mixture of dirt, which is good, and lots of 3cm fibers/hairs, which is not. I now have to spend a lot of time cleaning all the hairs off before I can feed them to my beardie. The sandy substrate used for the smaller BSFL was much easier to work with and I would recommend packing the prepupae with that instead - or at least don't include the fibers/hairs.

Great product, better company

I placed an order for black soldier flies larvae for composting purposes. When trouble with shipment meant that the box arrived heavily damaged and the larvae had escaped, the company was quick to rectify the situation. It's been a few weeks and the BSFL are doing well. I've already recommended them to family and friends, and will continue to do so in the future.

Excellent customer service

My package arrived with significant damage obtained during transport. Many of the prepupae had been able to escape out of the box (I wonder what the UPS driver thought). The remaining were all healthy. Symton immediately sent me a new shipment, even though it was no fault of their own.

Arrived one day early and very healthy

I would definitely order again from Symton.
I wanted these prepupae for starting a BSF compost and insect rearing experiment.
So far going well, but I'm not seeing any eggs from the BSF. Hope to get reproduction going here so I can keep the effort going.

Thanks for the review Penny! I hope all goes well with your experiment :)

Late- But fantastic!

The order shipped late but it didn't appear that there was a single dead maggot in the entirety of the two cups. The flies hatched out healthy and my chameleons loved them.

Very good

Thanks for insulating it, all of them arrived alive and wriggling

Excellent quality, fast shipping

Has lasted my baby bearded dragon over 20 days now; these are his staple, supplemented with other insects and veggies. He has been growing an inch a week and gaining 6-10 grams a week.
He eats these things like dragon popcorn. Happily snaps them up. Fully recommended.

Awesome!

My breaded dragon LOVES this BSF feed! We've tried others and have not had the same response from our baby. Our dragon is growing so fast since we started! Happy dragon makes a happy life!

Good quality for the price

Great feeder insect for the price. About 500 for ~20 including shipping, feeds our juvenile bearded dragon for a a few weeks mixing it up with other feeders. Hint: Order the sifter and scooper accessory with your *first* order, it really helps out a lot.

These folks went way above and beyond to get my order of BSFL to me. They guarantee their shipments and stand behind that guarantee! I am extremely happy with their level of service, and my dragon is extremely happy with their product.

Great company

After no fault of the company my packages arrived busted, and most the BSFL squashed or MIA due to the delivery driver. Symton was quick to respond to my email and sent me more to make it right!

Amazing Product, Amazing Company

Living in Florida it's often difficult to get insects mailed here in the summer months and expect them to be alive. Symton truly stands behind their guarantee and replaces anything that didn't live thru the summer heat. The product is always nicely packed, clean and my bearded dragon LOVES them (he eats 1000 per week)

Michael Jacobson
Very happy new customer :)

Just got my super fast 1st shipment of 500 large BSFL & I couldn't be more pleased. They were fat & active which had my veiled chameleon & bearded dragon gobbling them up! There were no dead ones that I saw & the price is a great deal. These were WAY better than I've gotten from other sellers by a long shot. You just have to see them to appreciate what you're getting. I'm gonna see how long these last & then get a regular delivery set up. So glad I happened to hear about this company. I'll be spreading the word!

Customer for life.

Ive been ordering from Symton for months now, with an order every week to every 2 weeks. Its heating up now and making it harder to ship these feeders out. I received my order of 1200 bsfl, and unfortunately they were all dead from the heat. I contacted Symton via email, and they immediately shipped out another same day. I got my order fast as always and they were alive. The fact that a company cares about their customers like this goes a long way for me. It wasnt their fault, (temps are different throughout the country) I know this, i didnt gripe, or complain. All i did was let them know, they didnt require me to send them pictures or any questions. They just shipped out another order for me. These guys are great, and their quality of BSFL is spot on. Its my beardie's main staple (with a variety of supers and hornworms) with the exception since he gets tired of them quickly lol. But i know their the best feeder for him so ol' Yondu will have to get over it.
Keep up the great work Symton!!

Best Black Soldier Fly Larvae around

My order was received in a timely matter as promised. The BSFL were loved and very much enjoyed by all my reptiles. I would highly recommend them.
Will definitely be ordering again in the near future.
