Norah,
A travel trailer? Love it!!!!!!!!!!! I was hoping this year I could get a room done for a sewing room. I have a spare room but I have these visitors that come every fall and stay until spring. And they are not human. We call them Lady Bug but in truth they are a Japnese Beetle. And altho the rest of the house has problems with them too. This room is unundated with them. I thought we had them licked this year. But alas to no avail. The only option you have is to close the door on the room until spring and then go in and clean up when they leave. I run in their and try vacumning them up everyonce in a while but it is hopeless to use as a sewing room. Oh well woe is me. lol.
I envy you. My luck they would probably envade it too. lol
