Beware of wasp traps, Valli
Those ones you see in garden centres let more wasps out than they trap. They then go and tell their mates where the food is. The best defence against wasps is a strong colony and you have just severely depleted yours.
Reduce the entrances down to two bee spaces. Have a look at a high efficiency trap such as the Waspbane. Placement is crucial, best located downwind of the hives. There is much good advice at http://www.waspbane.com. Just click on the beekeeping link there.
On another note, mentoring.
Never mind their standoffishness. Just ask. Admit you might be in trouble and are inexperienced and I'm sure somebody would step up.

Do look at the website.
Understanding how wasp colonies behave lets you tackle the problem most efficiently
