This feeder comes with six one-ounce dishwasher-safe plastic jars with lids to allow for easy changing of food.

1-3 hummingbirds will empty one jar of food in about 2 days (depending on the time of year, other available food sources, whether one bird is capable of defending the feeder from other birds, etc). However, it's best to change the food daily if you are truly worried about bees and wasps.

Instructions for use included.

Size approximately 10" x 3" x 10"
