Questions & Answers

9 Customer Questions

Where are these sourced from?
Answer by ChewyJan 06, 2020
This product was sourced in China.

How are the FlyGrubs (both the black soldier fly larvae and the mealworms) dried? Are they microwaved or freeze dried? Are they hollow inside? Thanks
Answer by ChewyFeb 02, 2021
When the grubs are fully grown, they are collected, oven dried then boxed. They are not hollowed out. FLYGRUBS are nutrient dense and contain, on average, 85x more calcium than mealworms, about 40% crude protein and about 27% crude fat.

How long does this box of worms last once opened? We want to get the 10lb version, but don't want it to go bad before we use it all.
Answer by ChewyApr 27, 2020
The shelf life for FLYGRUBS is 1 year from that date they were packed.

How much should I feed daily per bird?
Answer by ChewyMar 12, 2020
The recommended feeding is to give to chicken by the handful, scatter them on the ground, mix in with feeds or place in dish. A couple handfuls is recommended.

no 1 will eat this

My ducks, moor hens, and birds were all eating meal worms by the lb. 2 x a day. Until I ordered this kind. Not 1 of them will touch it after first taste, which they slung out of their beaks. The contents smell AWFUL. If these things are sewer worms, or cocered w pesticides, that could explain a lot. I have tried wasing the worms, and soaking in water first then rinsing. Nothing has worked. My poor feathered babies are eating bird seed to stay alive. Box is still full.

Chicken Party!

Our girls go wild for these! We love to sprinkle a scoop around their yard to encourage activity and give them something fun to do. The entire crew gets stirred up and excited to find them - it's like an Easter egg hunt. Love that they're more affordable than meal worms and that the smell is mild (I even kind of like it!).

These have been a hit!!!!

We don't have chickens, but we had a nest of four baby robins under our eves, and a family of sparrows in our front birdhouse. Thought it would be nice to help out the bird parents. Feeder regularly gets wiped out. I was worried I'd bought too large a box. Nope. Down to our last few. Highly recommend!

Wild birds don’t seem to like it

I have bought a different brand of dried larvae to use in my wild bird feeders before and the birds loved it. This brand not so much, like not at all. Now I don’t know what to do with an almost full box.

Wild birds love them

I mix these in with wild bird seed and put it in a platform feeder. The grubs are usually the first thing eaten and I'm seeing a lot more birds at the feeder: cardinals, catbirds, starlings (because of course starlings), mourning doves, robins, mocking birds, etc. This also encourages the larger birds to leave other feeders alone. So, I'm getting more finches and smaller birds at the other feeders.

Chicken treats

You probably think this product is a bit expensive, but it's a good protein for your birds, they love it, and it goes a long way. Your hens will love you for it.

Chicken candy

My girls are absolutely obsessed. The sound of me getting that big box out and they are going nuts. It is so funny. They gobble them down so quickly it is definitely something we will keep on hand. They love it so much.

MyDucks & Chickens LOVE these plump grubs

These are a great value. They arrived nicely packaged and the grubs are plump and full. Our chicken and duck hens come to the front of our house quacking and clucking for these treats.

Chickens and Ducks Love them

Been using the BSF as a more cost effective alternative to meal worms for over a year now. Getting the large box is an efficient means to maintain and monitor supply, and the BSF is a great treat and protein supplement for my chickens and ducks. The quality is very good and the BSF largely whole, the resealable bag keeps them fresh and easy to scoop out for dispensing. My ducks love this treat and come running with anticipation each morning.

Flygrubs soldier flies

I’ve bought these straight from the maker, but this time bought them from chewy because the price was good and free shipping. Clearly they are seconds because they are half the size of mealworms from the same company. First time I’m disappointed with chewy, they are usually outstanding.
