2. Yellow flowers on the hummingbird feeders attract bees and wasps.

Hummingbird feeders are a great way to attract these little birds to your yard. Place them where you can see them and you'll be entertained by their antics. There's a variety of feeders on the market, some are red, or clear. Some feeders have little yellow "flowers' on them for feeding ports. The yellow color attracts bees and wasps so remove those or paint them red before putting your feeders out in the Spring to avoid getting lots of the bees in the feeders.
