Does Hot Pepper Bird Seed Prevent Squirrels and Raccoons? 

In this video we do a little test to see if hot pepper bird seed really works at preventing squirrels and raccoons from eating your seed. We tried two different varieties of Mammal Mayhem Hot Pepper seed cylinders. They were hung in areas that were highly populated with squirrels and raccoons. Over 2.5 days, we didn't see a single squirrel or raccoon take a bite of seed. Typically, we get about a day of feeding time with a cylinder, so far there is plenty of seed left after three days of use.
