The HummZinger, HummZinger Excel and the Hummerfest feeders are inherently bee and wasp-proof because the syrup level is too low for insects to reach, but easily in range of the shortest hummingbird tongue. They may never find it in its new location, while the hummingbirds will barely notice that it was moved. If that doesn't work, take the feeder down for a day, or until you stop seeing wasps looking for it. You'll see hummingbirds looking for it, too, but they won't give up nearly as soon as the wasps. Contrary to popular belief, leaving your hummingbird feeders up will not interfere with hummingbird migration.
All birds migrate based on hormonal changes brought on by changing daylight hours.
In fact, hummingbirds can readily use the energy found at backyard hummingbird feeders as they begin their long migration journeys. We advise taking your feeder down when you feel comfortable or wait until you no longer see hummingbirds feeding for several weeks. Usually, its safe to take your feeder down after the first frost, but use your own good judgement. Try to keep your birdbath in the shade. This will cut down on the growth of algae.
