3B Protector cleans and removes dirt, soil, inanimate nutrients, and organic particles that contaminate birdfeeders, birdseed, and birdhouses. Our product is gentle and safe because it is made from all-natural ingredients which imitate natural cleaning processes that occur in nature. Aspergillus Havus (fungus aflatoxin) and Aspergillus Parasiticus are fungi that harm bird's immune systems. Birdhouses, birdseed and feeders can become infected with fungi, parasites and mold. 3-B Protector is exclusively designed to clean away these unwanted pests safely and effectively while not harming birds.
