Hi We are having quite a season for yellow jackets this year . They are everywhere . This is my first year beekeeping , I have a weak hive , only about six frames built out . Today I saw a yellow jacket walking around on the landing , then he walked in the hive without any objections . Both of my hives have been very busy bringing in pollen and nectar lately , goldenrod I guess . I opened the weak hive to see good brood pattern , but very little pollen and what little honey present was uncapped . About a month ago , this hive had some capped honey . Could the yellow jackets be robbing , or have they just used there stores . I began feeding today , because they have no stores .
