We’ve been using Mr Bird for several years and have been completely satisfied with the hot pepper squirrel repellent. That said, the consistency of their cylinders and cakes has been declining over the past year — cylinders arriving in pieces, crumbling within a day on the feeders, and generally not exhibiting the “cohesiveness” in their habanero resin. We tried the JCS Wildlife brand as an alternative and were immediately impressed with the tight, solid cylinders. Squirrels haven’t appeared either, so right now we’re going to ride with this product.
