Take a bucket of warm water and disolve four or five teaspoons of dish detergent like dawn. Put in a sprayer or spray bottle and douse the tree limbs with the solution.

Hornets don't attack trees. Sawflies-- plant-eating relatives-- do. If you see waspish forms, they may be wood-boring (hard to treat). Look for caterpillar-like larve on foliage. You can spray those.
