Thanks to everyone for your responses. Glad to hear there are some fellow wasp haters here on PT.

Bearing in mind that I mean from a distance, I do like bees, spiders, beatles and a lot of other insects. However, I really dislike earwigs and flies, I am also none to keen on ants either, mostly because they invade my home in the warm weather!

Thanks for the good advice Tonya. I certainly will follow it if I can ever find a nest. Trouble is I have no idea where it could be, or even if there is one. The three places where I have seen them are not really close to each other. Living room window and the kitchen sink area, close to back window, are both downstairs, and are both warm areas, but have a hallway between, and the time difference between one being seen in November and one yesterday seems to question the connection. The one I saw in late December was upstairs in my non heated bedroom, and was fully awake! (I was so glad I got to it before Ebbs, she is the champion bug catcher around here!) Though that bedroom is located over the kitchen, maybe there is a connection there ....
Oh, I give up!
