Have you ever pondered the question, What is a rainbow trout’s favorite food? If you’re an angler aiming to catch this vibrant species, understanding their diet can significantly improve your success. Rainbow trout are opportunistic feeders with a diet that ranges from insects to minnows, fish eggs, and earthworms. Their dietary preferences evolve as they grow, starting with water fleas in their youth and gradually incorporating larger prey as they mature.
Aquatic Insects: A Trout’s Delight
Aquatic insects form the primary diet of rainbow trout in freshwater environments. However, not all insects make the perfect lure. The key is to identify the insects that rainbow trout find irresistible, such as mayflies, midges, or caddisflies. These preferences can vary depending on the season and weather conditions. Remember, rainbow trout typically avoid insects that are too large. So, ensure your chosen insect is small enough to attract a rainbow trout. For instance, larger trout are particularly fond of smaller caddisflies in their pre-adult stages.
Larvae: A Seasonal Favorite
Larvae, the young form of several insects, are another favorite food of rainbow trout. The types of larvae available as potential bait can depend on your region and the time of year. To increase your chances of a successful catch on your next fishing trip, consider using colorful larvae readily available at stores like Walmart.
Small Minnows: The Chase for Easy Food
Small minnows, found in various water bodies across the US, are another food source for rainbow trout. Larger rainbow trout relish the chase of these small fish, especially if they appear wounded and thus an easy meal. Using a small minnow as bait on your next trip could be an effective strategy to attract bigger rainbow trout.
Worms: The Classic Bait

Rainbow trout have a particular fondness for worms, a common bait available in most local markets and abundant in their natural habitats. Various types of worms can be used as bait for rainbow trout, with nightcrawlers being one of the most popular choices. Using nightcrawlers as bait is almost a guaranteed way to catch a rainbow trout on your next fishing trip. If you’re looking for a cost-effective way to fish with worms, consider searching for earthworms in your yard. Alternatively, your local fishing store or Walmart should have a stock of worms. The key to using worms as bait is ensuring they don’t fall off the hook when you cast your line. For a comprehensive tutorial on setting up with worms, watch this video.
