While these insecticide-containing guards protect against ants and wasps, they also kill honeybees and bumblebees (as well as other native bees) which might visit the feeder -- & all of these bees are in big trouble! So no sure if this is really a environmentally-sound solution.

We have had little trouble with our two feeders this year since we also have a lot of flowers in bloom as well as fallen fruit from apples and cherries -- maybe the wasps prefer these?

Our major hassle is a sudden increase in hummingbirds (which are starting to migrate) and one-two very aggressive individuals which try and dominate the whole area. "Share" is NOT a word in the hummer vocabulary!
