Grub Love 101:
3 Tips to Judge a Grub


After learning how black soldier grubs naturally range in appearance, you know that color doesn't tell the full story.

In fact, it’s impossible to tell where the grubs are grown or even how healthy they are simply by looking at them.

So how do you know which batch of grubs is the best choice for your pets?

Instead of "judging a grub by its cover," the only way to evaluate the health and safety of your flock’s food is by checking the label.

In order to discover what truly matters to you and your flock, you can check for these 3 items before making a choice.

1. How are the grubs harvested?

What do the grubs eat? Anything funky? Whether grubs are grown in the USA or around the world, The FDA requires that grubs eat feed grade material. This can mean a lot of things.

Pre-consumer food waste is the best form of feed for grubs. This is food that hasn’t been touched by the end consumer, like veggies at a grocery store or bananas from a smoothie shop.

*All Grubblies are naturally harvested on a diet of pre-consumer food waste using fruits, vegetables and grains.


How are they dried?  Instead of choosing grubs based on color, you can check to see how they’re dried (oven-dried, freeze-dried, or microwaved) to judge what's important to you.

*All Grubblies are dried in a variety of oven-dryers. Whether they "tumble dry" or lay flat, the grubs will appear yellow, brown or black and have the same nutrient levels.

2. Where are the grubs grown?

Are they safely harvested? Most grubs and mealworms come from China where food safety is a concern due to its history of pet food scandals.

Given China’s track record, it’s difficult for the FDA to confirm what the grubs actually eat, and if anything was transmitted to the grubs.

In order to avoid grubs from China, carefully check the labels. Although you’ll find misleading phrases on products (like "Packaged in the USA"), you can learn a few easy tricks to avoid pet food from China.

At Grubbly Farms, you can find locally grown grubs (from $16.99), as well as grubs harvested around the world (from $12.99).

*Regardless of where they are grown, all Grubblies are safely and sustainably harvested on FDA-approved grub farms with uncompromising standards. You will never find hidden labels that say “Product of China.”

Are the grubs tested for potential contaminants and pathogens?

*This is a requirement by the FDA and a guarantee for all Grubblies. Every batch is meticulously tested for any pathogens or contaminants to ensure the highest levels of food safety for your flock.

3. What are the health benefits?

How will grubs improve the health of my flock?

As you know by now, color is not indicative of how healthy the grubs are. Just like coffee beans also vary in color and shape, you’ll still get the benefit of all that lovely caffeine to jumpstart your day.

Whether they are dark brown or yellow, black soldier fly grubs are inherently packed with nutrients to benefit your flock. Every peck of grubs is packed with protein and calcium for strong, protective feathers and higher quality eggs.
