A premium hot blend designed for birds only. Industry studies show that squirrels are listed as the reason for people leaving the bird feeding category. Squirrels dominate feeders, create a mess and eat much of the seeds, nuts and fruits. After much development and product testing, we created Sizzle N' Heat, a squirrel-deterrent product. While this is not a squirrel-proof product, our studies showed it to be a very effective squirrel deterrent. While squirrels may still visit and feed at feeders, once they get a taste of the hot seeds, most will look for other sources of food. Attracts Cardinals, Chickadees, Finches, Grosbeaks, Jays, Nuthatches, Titmice. As with any Wild Delight product, ensuring the best bird feeding experience is the goal. So Sizzle N' Heat is filled with the same highly desired ingredients birds love with none of the filler ingredients. Made with chili peppers, a strong irritant.
