Wonder if anyone can help. I have had some insects identified as Gall wasps/ Gall midges and Chalcids. This has been by an environmental service. It is difficult to get pictures as they are only about 1mm or less. IF you have any idea about life span or where they are likely to be breeding I would be grateful as they have taken over the house! I have a very large oak outside and had gall apples. Have tried just about everything to get rid of but to no avail. They are very noisy in the a.m and I permernanly feel itchy.
