Wasps everywhere

My poor hives are taking a battering from the wasps, I have reduced down the entrances but still I can see the wasps taking out my bees. They are after both the honey and the young larvae, you can see the wasps flying out of the hive with a young bee.

I have made up some wasp traps that only catch wasps and not the bees, taking a water bottle you need the following:
- cup of water
- cup of sugar
- 1/4 cup of white wine vinegar
- 1/4 of an old banana peel
