european hornets

Postby Grammyx4 » Tue Jun 14, 2011 5:29 pm

I have european hornets chewing up my lilac tree. Is there something I can do to persuade them to go bother someone else. There is a fish pond about 15 to 20ft away and flowers planted under the tree. I would prefer to use something organic, but at this point, will take any suggestions. Those things are scary, big!!

These hornets are stripping bark from the lilac for nest building material. You can spray the lilac trunks with liquid Sevin to keep them from chewing on the bark and damaging the lilac. If you are careful to just keep the spray on the tree trunk, there shouldn't be any problem with the pond. As far as an organic product, pyrethrin based pesticides may work but they are also toxic to fish and aquatic insects so you need to be careful about spray runoff getting into waterways as well.
If you are able to locate the nest, you can spray the opening at night with a wasp and hornet spray. Always read and follow the label directions when spraying pesticides.

Is there a time of day that is better to spray the trunks of my lilac. Can I go ahead and spray now even though they haven't appeared yet on the tree. Usually it is in July when they show up. I have noticed that they stay on the tree during the night, instead of going back to their nest.
