I opened a window in my house that had probably not been opened for 5 years. I slid down the screen, was enjoying the breeze, and then noticed that there was an active paper wasp nest up at the top, between the top sash and the outer storm window.
I closed the window again. I now have my very own ant-farm-like wasp nest under glass, with about 12-20 live wasps and a few filled-in hive cells (eggs? pupa?).
Two hot days later, they are still active, and none can leave the confines of the glass-and-screen sandwich. Without water or food (besides each other and perhaps a few very small insects that get around the ill-fitting screen), how long can I expect them to survive? If I had a clear shot at the nest, I’d just hose them with wasp spray, but the angle’s no good (and I’m not about to open the screen to get a better angle).
