Our Red Giants are fed an oil based vegetable dye to give them a pink color that is more visible to fish in the water. Our dyes are certified for use in foods, drugs, and cosmetics (FD&C Red #4). While the dye isn't harmful to your reptiles, we prefer that you feed them our all natural Golden Giant mealworms.

Most customers who choose Rainbow Mealworms do so because our regular mealworms are all natural, and so feeding a naturally raised giant mealworm is a perfect choice.


Our founder Fred Rhyme discovered the secret to growing the Giant Mealworm in the 1950s, then went on to develop the Reds in the 70s!


These Reds are thicker and longer than ordinary mealworms measuring 1.25" with a reddish color.  They are used primarily for fishing as the red color is more visible to fish giving you strike after strike.  We impart the red color with a vegetable based dye.


Trout, Bass, Crappie, Perch, Bluegill and other panfish devour these brilliant Red Giant Mealworms!
