Spring is the best time to spruce up the yard - plant flowers, build birdhouses, hang a new set of wind chimes, and do some thorough cleaning of your bird feeders. Dirty and dilapidated feeders can be harmful to our bird friends. Bacteria, mold, mildew, broken plastic, jagged wood pieces...all need to go. If your feeder is just dirty, a little elbow grease and a bottle brush goes a long way. Scoot Bird Feeder Cleaner is our favorite enzyme action product. It works all types of feeders and is not harmful to birds or the environment. For your hummingbird feeders, we recommend a 10 parts water to 1 part plain bleach mixture instead of soap, which can leave a residue. Have a problem with yucky, black stuff on your hummer feeders? Change the nectar more often (at least twice weekly) so mold and mildew won't have a chance to grow.
