Said to be the BEST Hummingbird Feeder EVER!! Introducing the new solution for cleaner feeders. Dishwasher safe (place all parts of the feeder in the top rack of the dishwasher). When using soap to hand wash the feeder, or when using a dishwasher, always follow up by rinsing with a mild bleach and water solution to rinse the parts before re-filling with sugar and water. Unique 2 piece base. Innovative flow-control design. High-quality removable parts. Bee resistant inner base. Finally you can clean the inside of a hummingbird feeder. Wide mouth jar for easy cleaning and no mess when adding sugar and water. No drip design even in highwinds! Replacement petals available in yellow and red. "This is the best new feeder to hit the market in years! Having been fortunate enough to test the feeder during the design stage, I consider it a huge success! In my opinion, it may just be the last hummingbird feeder that hummer lovers will ever have to purchase. It is worth every penny of the cost. It is a rugged beauty that the hummers love! I have 40 of your feeders hanging in my yard NOW!" - Bob Sargent (President, Hummer/Bird Study Group, Inc., and Master Bander), Trussville, Alabama. Regarding Bee/Wasp question on the SE6002
