I wanted to thank-you for your information on the internet regarding mud daubers. I installed a window air conditioning unit and did not cover the exterior area on either side of it allowing exposure to the area between the interior and exterior windows. The interior side in completely sealed. I noticed a nest about 2 weeks ago at the very top of the inside window area and identified it as a mud dauber nest, the insects are yellow and black. Since then 2 more tubes about 2 inches long each have been added and of the 3, 2 have been closed the 3rd remains open. I was going to try and knock them down but it meant removing my AC unit to get to them so I have since sealed up the outside so they cannot get in and continue building more nests. I realize that the 2 sealed nests will probably hatch sooner than later and whatever is inside will have no place to go as the area is now sealed. Is it better to just leave them now and after the nests hatch the new insects will die in this sealed area, then when I remove my AC unit in the fall I can get rid of anything that remains or is there any danger in not completely removing the 3 nests now?
